Ed Miliband announces "green loan energy plan"

2010-03-08T09:18:00.002Z

Energy and Climate Secretary Ed Miliband has announced a "green loan" energy plan for homes, to help people pay for improvements to their homes to make them more energy efficient. Home owners can borrow up to £10,000 to make improvements to their home.

Consumers will be offered long-term loans to install insulation, solar panels or other green technologies, which they can repay through energy bills, spreading the upfront cost over a number of years. The loan remains attached to the property where the technology was installed, allowing the resident to move house, knowing the new owner has taken over the repayment for the technological system.

The Pay As You Save (PAYS) scheme, which was first announced last year, has already been trialled by around 500 homes. Loans are expected to be available from 2012.

Renewable Heat Incentive (RHI) for Solar Thermal Panels

2010-02-28T22:06:00.002Z

The government has announced a new feed in tariff for low carbon heating technologies. This is planned to come into effect in April 2011 and will guarantee payments for those who install solar thermal systems.
Under the proposed tariffs the installation of a solar thermal system will provide an income of 18p per kwh of heat produced.The installation of solar thermal panels in an average semi-detached house with adequate insulation levels could be rewarded with £250 a year plus an additional saving on fuel.

This makes already solar thermals even more attractive from a financial and environmental point of view.

Economy 7 - Is it worth it?

2010-02-26T11:18:00.003Z

Many of our customers have historically been signed up to an economy 7 package.

Given the name I can understand how people would assume that it must be good value. Consumers often forget that to receive a very attractive night rate you must pay more for electricity during the day.

This means that the savings are not always there. To prove the point I have done few basic calculations.

Is 40% of your total electricity usage at night?
Typically economy 7 rates are presently in the region of 15p/kWh during the day and 5p/kWh at night. A typical standard rate is 11p/kWh for any time usage.

This means that for Economy 7 tariff to save the home owner money they must use around 40% of their electricity at night. For homes that are heated with storage heaters this is easily achieved but for home that use gas or even a heat pump this is often not the case.

For most people even putting the washing machine and an hot water cylinder immersion heater on at night will not increase night usage to 40% of their total.

I am not saying that Economy 7 is a waste of time but it is important to realise that it is not always the cheapest option.

Renewable Heat Incentive (RHI) for Heat Pumps

2010-02-22T23:37:00.006Z

The government has announced a world first in a feed in tariff for low carbon heating technologies. This will come into effect in April 2011 and guarantee payments for those who install ground source heat pumps and air source heat pumps.
Under the proposed tariffs the installation of a heat pump will provide an income of 7.5p per kwh of heat produced for air source heat pumps and 7p/kWh for ground source heat pumps.
The installation of an air source heat pump in an average semi-detached house with adequate insulation levels could be rewarded with £1,000 a year and lead to savings of £200 per year if used instead of a conventional fossil fuel system. This means that the payback for a heat pump is under six years, and if you are replacing a boiler anyway, then the payback is only 3.5 years.

So these systems are now enormously attractive from a financial and environmental point of view.

Ed Miliband, secretary of state for Energy and Climate Change said "The guarantee of getting an income on top of saving on energy bills will be an incentive to householders and communities wanting to make a move to low carbon living. The feed-in tariff will change the way householders and communities think about their future energy needs, making the payback for investment far shorter than in the past."

Leicestershire Community Climate Change Grants

2010-02-18T23:32:00.002Z

Community Climate Change Grants can provide up to £5,000 towards community projects in Leicestershire. If you are a registered charity, village/community building, community group, religious organisation or parish town council you could be eligible for the grants. As long as your project helps to improve energy efficiency and reduce the impacts of climate change it will be worth contacting Leicestershire County Council.

Intelligent Energy Solutions are MCS approved installers which is a requirement for all government grant schemes and incentives.

Solar PhotoVoltaic (PV) and Wind Turbine Feed In Tariffs (FIT)

2010-02-15T23:21:00.001Z

The government has confirmed new feed in tariffs for electricity generating microgeneration systems.

From 1st April 2010 41.3p can be claimed for every kwh that is generated from solar PV panels, as well as this, the rate is guaranteed for 25 years and linked to inflation. Add to this the saving made for not purchasing the electricity and again the money received for exporting, means there has never been a better time to install a solar microgeneration system in the UK.

The table below shows the new tariffs available, if you would like more information then please visit: http://www.lowcarbonbuildings.org.uk/

- Solar PV new build (< 4 kW) 36.1p
- Solar PV retrofit (< 4 kW) 41.3p
- Solar PV retrofit (4-10kW) 36.1p
- Wind turbine (1.5-15 kW) 26.7p
- Wind turbine (15-100 kW) 24.1p

This is only available to customers who have systems installed by an MCS approved installer such as Intelligent Energy Solutions.

Government Announces Details of April 2010 Feed in Tariff

2009-08-10T11:05:00.002+01:00

The Government has announced the details of the proposed feed-in tariff for microgeneration systems. Small wind turbines and solar photovoltaic systems will now carry the following benefits:

- 36.5p/kWh for small solar photovoltaic systems up to 4kW and 28p/kWh for systems up to 10kW.
- 23.0p/kWh for small wind turbines between 1.5kW and 15kW.
- Replaces the current ROC system which pays 10p/kWh.
- Effective as of the 1st April 2010, but all systems commissioned from now on will qualify.
- Systems installed from now until April 2010 will be eligible for both LCBP grants AND the new tariff.

Double your ROC's

2009-04-27T16:35:00.004+01:00

All electricity companies in the UK have an obligation to generate a proportion of their supplied electricity from renewable sources. They achieve their targets partly by buying Renewable Obligation Certificates (ROCs) from the private microgenerators. A member of the public can become a microgenerator by having a wind turbine or PV system installed.

Recent changes have seem the amount of ROC's awarded to microgenerators double so now a householder will be awarded 2 ROC's rather than 1 for every 1000kWh they produce.

We Support Solar Campaign

2009-04-16T21:25:00.003+01:00

Intelligent Energy Solutions has joined the 'We support Solar' campaign. This campaign is designed to unite support for an attractive feed in tariff for solar PV installations. As things currently stand feed in tariffs are improving and energy companies such as Good Energy offer 16p for every kWh generated by the PV system. However, some energy companies still offer extremely low feed in tariffs. There is lots of room for improvement!

The government has put the feed in tariff on the agenda in 2010. The campaign wants to ensure that this opportunity is not missed and that the government responds to public demand. This will involve setting the feed in tariff at a level which will encourage large numbers of the general public to invest in this Co2 busting technology.

Leicester Solar Grant Scheme

2009-03-25T13:05:00.005Z

Leicester City Council in conjunction with Groundwork has launched a new grant scheme targeted at solar installations.

The grant allows a household to claim £2250 against a solar thermal (water heating) or a solar PV installation. The householder would also be eligible for an additional grant from the Low Carbon Buildings Program. This means that a house holder could claim £4750 against a solar PV installation or £2650 against a solar thermal installation. Depending on the size of the system would be more than half the installation cost.

Intelligent Energy Solutions is an approved installer on the scheme, please contact us for further details.
Click here for the Leicester Solar Grant Scheme details.

MCS Approved Installer

2009-02-01T21:37:00.000Z

Intelligent Energy Solutions have received MCS accreditation for the installation of Solar PhotoVoltaic Panels, Ground and Air Source Heat Pumps and Solar Thermal Water Heating systems.
The approval means that customers now have access to a whole range of government and local council grants. It also gives customers piece of mind that installations will be to the highest quality using approved methods and materials.

The approval process was long and involved with the Buildings Research Establishment inspecting previous installations and making sure that the whole process from customer enquiry to commissioning of the system meets the required standards.

Solar, Heat Pump, Wind & Rainwater Harvesting Self Survey Forms

2009-01-23T11:49:00.004Z

For anyone who is keen on renewable energy, but at a loss where to start, Intelligent Energy Solutions has the answer. It has launched a series of easy to complete self survey forms for all of the technologies they offer.

The purpose of the self survey forms is to enable the customer to understand the important factors when asking for a quotation for a renewable energy installation. The information provided can be used to generate a detailed quotation from IES without the need for a site visit. This means that IES can keep the installation costs down, and the customer has a better understanding of what's involved. If a price is quoted that later (due to a site visit) cannot be honoured, the customer will have the option of having their deposit refunded.

The forms are in PDF format with interactive form features. As such, the form can be filled out and returned on line or the customer can print and complete the form manually.

The forms are accessed by the Intelligent Energy Solutions VIP area. Fill out the enquiry form or pick up the phone to obtain login details. This area of the site also contains pricing and lots of other useful information.

Solar Thermal Panels and Water Storage Cylinder

2009-01-05T10:23:00.005Z

To be able to install a solar thermal water heating panel system you need a store of water in your property. I am often asked...

Can I keep my existing Hot Water Storage Cylinder/Tank?

Many companies offer customers the option of keeping their existing hot water storage tank. This reduces the cost of installation significantly. However, is this the right thing to do?

To determine whether this is a good idea we should look at why the cylinder is normally replaced. For this article I will use the word tank and cylinder interchangeably.

Normal hot water tanks only have a single heating coil that comes from a boiler. This heating coil enables the boiler to heat up the tank. A new tank is normally required so that the tank has a second heating coil. This coil can be connected to the solar panels.

Hot water rises so in a normal tank the hot water is at the top and the cold (inlet) is at the bottom. This means that it is best to position the second heating coil at the bottom of the cylinder. This enable the solar panels to heat up the coolest part of the tank. It is not uncommon for the top of the tank to be very hot but the bottom to be at the mains water inlet temperature of about 10 degrees. If configured in this way, on a cloudy day, when the panels are only at about 25 degrees they can still make a significant impact on your heating bills. This is because the 25 degree water can be used to heat the 10 degree bottom of the tank to 25 degrees. The final heating can then be done by your boiler.

Systems that utilise the existing tank normally operate in one of two ways. Take a look at the diagrams below.

Immersion Heater Solar Coil

This device screws into the hole in your cylinder usually dedicated to an immersion heater. This consists of a small pipe that is coiled. Apart from being a poor design for a heating coil (due to the restriction of the immersion hole), Sadly most immersion fittings are at the top of a water tank (usually designed to boost the top of the cylinder). So if the top of the tank is at 50 degrees the solar panels will need to be significantly higher than this before the system will operate.

This heavily compromised configuration mean that the output from the panels is enormously reduced. This reduction in performance would certainly outweigh the cost of replacing the water cylinder for the twin coil variety.

Direct Solar Water Heating

The other method of retaining the original cylinder is to pump the actual water you use through the solar panel. This type of system pumps water from the bottom of the cylinder through the solar panel and then back into the top of the cylinder. This method completely upsets the natural way in which the hot water rises to the top of the cylinder. This type of system would not operate if the top of the tank is hotter than the panel. Unless the tank is cold or the the sun is shining brightly the system will remain switched off.

These types of system give the user the sense of having a solar heating system without many of the benefits. This is no good for either the environment or your bank balance.

As a result Intelligent Energy Solutions only fit twin coil systems for this type of application. We always make sure that what we are fitting will give you highest performance and the best return.

Ecodan Heat Pump Intelligent Controls

2008-12-12T13:41:00.005Z

Intelligent Energy Solutions have launched their brand new 'Intelligent Control Package'.

The control is designed specifically for the Mitsubishi Ecodan Heat Pump and separates Intelligent Energy Solutions from their competitors who may simply install an Ecodan system with a conventional boiler control system.

The new control system introduces cost saving and comfort improving features such as:-
- Heating Optimisation - the control system decides when the system should switch on so that the property is to temperature for the target time.
- Three home temperature settings, On target temperature, Off minimum temperature and frost protection (holiday mode).

The heating optimisation feature enables money to be saved in the milder months because the system will automatically switch on later at times when the property will heat up faster.
The Off minimum temperature setting enables the heat pump to control the temperature at night as well as during the day. This means that the system will not allow the home to drop below a certain temperature, perhaps 15 degrees. This means that the system will be able to heat up the home rapidly when morning comes.

This control system integrates seamlessly with the Ecodan flow temperature controller which has cost saving features such as Ecoheating mode. This mode uses weather compensation programs to determine the radiator/underfloor heating flow temperatures. This means that in milder weather the system will run the heating system at a lower temperature. Lower temperatures will dramatically improve the system efficiency and will help the 'Intelligent Control Package' to control the room temperatures more accurately.

The control system is simple to operate and requires minimal (if any) intervention from the owner.

The Intelligent Controls for the Ecodan are packaged with a high performance unvented copper water cylinder that will out perform stainless steel cylinders. Copper conducts heat better than stainless steel. This means that water can be heated more quickly and efficiently with the copper cylinder used by Intelligent Energy Solutions.

For more information or a discussion about how our systems can benefit you please call 01509 891256 or email sales@iesolutions.co.uk.

Ground Source Heat Pump - Lake Installation

2008-11-14T19:40:00.001Z

Lake Loop!

Ground source heat pumps operate by upgrading low grade heat to higher temperatures suitable for heating homes and hot water.

This normally means installing a number of pipework loops in the ground next to a property. This was not the case for the latest project for Intelligent Energy Solutions in Leicestershire.
This customer has a large man made lake at the back of their house.

"This is ideal to use as a heat source as water conducts heat so well." said Intelligent Energy Solutions Managing Director, Peter Searancke. "The lake will be relitively warm all year round".

This means that large amounts of heat can be extracted from the lake to heat an over 700m2 property and in door swimming pool. With expected efficiencies in excess of 450% the running costs will be extremely low for such a large property.

The photo shows the finished result. As you can see there is no sign of the 3000m of pipe that will provide over 50kW of heat for the property.

Intelligent Energy Solutions install ground source and air source heat pumps for domestic and commerical properties.
Please contact them for further details.

OWL Wireless Energy Monitor

2008-11-07T11:55:00.005Z

Wireless Energy / Electricity Monitor
Intelligent Energy solutions have recently started supplying the OWL wireless energy monitor.

This clever little gadget monitors your electricity usage in real time and displays the usage on a neat wireless portable display.

Easy to Install
The unit is easy to install. You simply fit the batteries (included) and clip a large peg over one of your meter cables by your electricity meter. This unit then automatcially transmits wirelessly to the display.

Save 25% off your electricity bill
The system makes you more aware of where your electricity is being used and this enables you to make better decisions as to how you use your electricity. For instance, if you switch on a 100W light bulb the system tells you that you are using 100W more than you were. It will also tell you the cost of doing this. What surprises most people is that when they switch 'everything' off they are still using 100 - 300 Watts. The challenge is then to work out which 'hidden' appliances are still drawing electricity.

The manufacture says that it will save you 25% off your electricity bill.

The system tells you:-

1. The rate at which you are using electricity in Kilowatts.
2. The cost of the electricity you are currently using
3. The Co2 emmissions of the electricity you are using
4. Temperature of your home
5. Humidity of your home

Intelligent Energy Solutions are selling this neat device for £39.95 (inc VAT & P+P), while stocks last. Call us now to get yours, while stocks last.

To order a unit either pick up the phone or enter "Energy Monitor" with £39.95 as the sum in our payments page. When diverted to our card payment page include your address and contact details. We aim to dispatch within 24hours by 1st class.

Surge of interest in heat pumps for winter

2008-10-20T11:44:00.000+01:00

With the days drawing in and the heating being switched back on for the winter many people of remembering the nigglings doubts that they have over their existing old boiler.

It's easy to forget how your boiler struggles when it's summer time and it's switched off.

This fact has lead to a surge of interest in ground and air source heat pumps at Intelligent Energy Solutions. Remeber that your boiler only has a life span of about 10 -15 years so if you are approaching this milestone don't wait for your boiler to fail. Call Intelligent Energy Solutions now so that you can have the work done at your own conveinience.

Remember that heat pumps can reduce your heating and hot water bill by upto 75%.

Mitsubishi Ecodan Flow Temperature Controller Launch

2008-10-10T11:31:00.000+01:00

Mitsubishi has recently launched their new flow temperature controller. This useful box of tricks enables the Ecodan air source heat pump to be used with other water storage cylinders other than the Boilermate from Gledhill.

Previously Ecodan installations were restricted for use with a Gledhill package. While being an excellent package this reduced the flexability as to what Intelligent Energy Solutions could specify for their customers.

With the new flow temperature controller, the options for the Mitsuibishi Ecodan system have increased significantly. The system can be installed with any size storage cylinder and with any programmable controller and thermostat.

For more information on the Mitsubishi Ecodan air source heat pump have a look through the heat pump product category in this product journal or contact Intelligent Energy Solutions on the details above.

Leicester Mercury - Big Green Switch

2008-09-25T16:20:00.006+01:00

The Leceister Mercury have just published a feature about Intelligent Energy Solutions' heat pump installations.
The article, written by Adam Wakelin, likened the heat pumps to the energy equivilent of alchemy. The air source heat pumps extract heat from thin air!

The article talked about how the air source heat pumps were effective down to sub zero temperature of -20 degrees. The system are able to heat domestic homes and hot water and make a saving of around 30% when compared to mains gas. The savings are even greater when compared to oil.

Intelligent Energy Solutions use the Mitsubishi Ecodan heat pumps. For further information about this particular product call IES now on 01509 891256 or download the brochure by clicking on the Ecodan link.

Underfloor Heating - Luxury or Necessity?

2008-09-17T09:29:00.005+01:00

Why do renewable energy companies recommend underfloor heating for heat pump installations?

The answer is simple. Underfloor heating runs at lower temperatures than conventional radiators. Heat pumps prefer to output lower temperatures as this makes them more efficient.

Is underfloor heating a necessity?

This depends on the heat pump used, some high quality heat pumps (used by Intelligent Energy Solutions) can output temperatures up to around 55 degrees. This is a scolding temperature and most radiators will give the required output at this temperature. The reason that the radiator will function at a lower temperature is because most radiators are oversized by the installing plumber anyway.
The efficiency of the heat pump can lead to massive savings when compared to both gas and oil fossil fuel boilers.

However, in an ideal world the heat pump will run most effectively with underfloor heating.

Ice Energy Heat Pumps Installer Partnership

2008-09-17T09:15:00.004+01:00

Intelligent Energy Solutions has agreed to a partnership with ground source heat pump, market leaders, Ice Energy.

Intelligent Energy Solutions have been using Ice Energy heat pumps for some time. Managing Director, Peter Searancke said "We shopped around before deciding to use the services of Ice Energy for our ground source heat pumps. They offer a great package including quality equipment, accessible grants, excellent technical backup and a 5 year parts and labour warranty".

In conjunction with Ice Energy, Intelligent Energy Solutions feel that they offer an excellent product that can be designed and installed to cost effectively heat many different types of property.

The Rich Get Richer With Renewable Energy

2008-08-31T16:41:00.000+01:00

We have often thought about fuel poverty and other political issues of the day.

This seems to be a major problem with modern renewable energy technologies.

The investment cost is relatively high, and to make this investment the owner needs to take long term strategic view. This type of approach unfortunately is often not available to the poorest members of society.

The problem, is that the members of the public who could benefit most from renewable energy cannot afford the upfront capital cost.
Inevitably this is another example of how the rich get richer and the poor get poorer. The rich have spare funds that they can invest in a solar panel, wind turbine or heat pump installation. This investment then goes onto reduce the fuel cost outgoings for the owner.

Progress should be made where this type of technology has a greater level of government funding for those who really need it.

Solar and Wind Feed in Tarrifs Improve

2008-08-24T16:28:00.000+01:00

Electricity prices are through the roof so the time has never been better to start generating your own electricity.

Better Feed in Tariffs

Tariffs have slowly been improving over the past couple of years. However, 'Good Energy' and 'Ecotricity' have just lifted the bar!
They offer a tariff where they will pay you for everything that you generate and not simply the spare electricity. The rate they offer is 9p per unit. This means that you save twice, you save the money from buying the electricity in the first place but you also get paid for generating it. This could equate to more than 20p per unit.

People often take about how far ahead Germany are in respect to microgeneration tariffs but the UK is genuinely catching up.

Are Air Source Heat Pumps Effective?

2008-08-16T16:11:00.000+01:00

Air source heat pumps work in a similar way to ground source heat pumps but extract heat from the air outside rather than the ground.
They upgrade this heat using a compressor circuit (similar to that found in a fridge).

Suitable for domestic home heating

The system does not generate it's own heat it simply moves the heat from one place to another. This means that it can have an efficiency that is greater than 100%.
Typically over a year an air source heat pump could have an efficiency of around 330% when heating a domestic home (including domestic hot water). This means that for every unit of electricity that it uses it generates 3.3 units of heat.

A modern high efficiency gas boiler has an efficiency of around 90%. This massive efficiency advantage means that the system will save you money off your fuel bills.

Comparing the system to a gas boiler you should save around 30%. Given the cost of oil, when replacing an oil boiler the savings can be up to 60%.

There are some design considerations when retrofitting a heat pump, these have been discussed in previous posts.

This type of heat pump can also be used for heating swimming pools.

Renewables - Enhanced Captial Allowances

2008-08-07T18:41:00.001+01:00

Why should businesses invest in renewable energy?

The government introduce the enhanced capital allowances scheme in 2001 to encourage businesses to invest in low carbon technologies.

In essence the scheme means that companies who invest in certain energy saving technologies can claim 100% of the cost against your profit for that year.

Capital allowance for plant and machinery is normally only 20% each year. So if you were considering buying a conventional boiler and choose to buy an energy efficient heat pump instead you would save a considerably amount in tax. This could equate to over 30% of the value of the heat pump.

If this sounds interesting you should talk to your accountant for further advice.

British Gas increase gas price by 35%

2008-08-01T08:02:00.002+01:00

British Gas owner Centrica says it is raising gas prices by a record 35% and electricity prices by 9%.

The UK's biggest domestic energy supplier said that the price hikes would take place with immediate effect, it blamed "soaring wholesale energy prices".

Biggest Single Increase

Watchdog Energywatch said it believed the 35% gas bill rise was the biggest single increase in the price of a utility seen to date.

A report prepared for Centrica earlier this month warned that annual average gas bills could rise from £600 to more than £1,000 early in the next decade.
Centrica said that wholesale gas prices in the coming winter would be up 89% on the previous winter.

Diminishing Gas Reserves

It added that the UK was suffering from diminishing gas reserves, and estimated that the UK would import 40% of its gas this year compared with 27% last year.

Mitsubishi EcoDan Air Source Heat Pump

2008-08-01T00:00:00.003+01:00

Intelligent Energy Solutions Ltd has become an approved EcoDan Air Source Heat Pump installer. The EcoDan product introduction presents an exciting time for Intelligent Energy Solutions and Mitsubishi.

The EcoDan heat pumps works like a normal air source heat pump but has been specifically designed for the domestic new-build AND retrofit market.

Mitsubishi have been very much focused on the requirements of the domestic home owner when designing the EcoDan system. This careful product design is evident in a number of ways from quiet running to coefficients of performance that means air source heat pumps can now compete with high efficiency gas boilers.
When compared with a modern gas boiler the EcoDan Heat Pump can not only saves up to 50% of the Co2 output it can also save up to 30% of the running costs.

When comparing the EcoDan heat pump with a modern oil boiler the savings could be up to 60%.

Fossil fuel costs are rising faster than electricity

2008-07-28T08:37:00.005+01:00

Following the recent energy price rises it is worth looking at any trends that are developing.

Recent trends show that while electricity prices are increasing, they are rising at a slower rate than fossil fuels such as gas and oil.
We believe that long term there will be many more sources of electricity than fossil fuels. These include wind farms and solar photovoltaics. Therefore we expect this trend to continue.

Gas is no longer a cheap fuel

This means that heat pump technology is set to become more and more popular as it runs on electricity and heat from the sun.
Historically mains gas was a very cheap fuel vs electricity. However gas prices are rising faster than electricity and heat pumps have efficiencies in excess of 400%, gas is no longer a cheap fuel.

EDF Energy Price Rise

2008-07-25T08:22:00.003+01:00

EDF have announced price rises for gas and electricity.

Gas prices will rise by 22% and electricity by 17%. They blame the increase on record wholesale energy prices.

This rise comes after a 12.9% and 7.9% price increase on gas and electricity respectively in January of this year.

Heating Oil Doubles in Price over last 12 months

2008-07-15T12:53:00.005+01:00

We all know that fuel prices are rising but sometimes we forget just by how much they have risen.

With regard to heating oil the prices have doubled in 1 year. See graph below.

This graph shows the average price of kerosene 28 over the past 12 months. This dramatic increase paves the way for more fuel efficient alternatives such as solar water heating and ground & air source heat pumps. Please click the links to read how these technologies could reduce your fuel bill.

World's Largest Solar PhotoVoltaic System

2008-07-08T12:57:00.004+01:00

The world's largest rooftop solar power station is being built in Spain. The 12 megawatts of power covers an area of around 2 million square feet. The roof space is owned by General Motors but is being leased out to Veolia Envirnoment and Clairvoyant Energy.

The £40 million investment will see an output of more than 15 million kilowatt hours.

This shows that PV is a very viable prospect for commercial investment. Obviously smaller systems are available for domestic and commerical premises. Typical installations range from 1kW to 20kW peak power. Installation costs are typically around £5500 per kW. In a good position each kW of peak power should generate around 800kWh per year.

Wind Turbines - Bigger is better?

2008-06-30T16:28:00.000+01:00

Many people wonder about how quickly wind turbines pay back.

Obviously it is crucial that the position is good and doesn't suffer from turbulant air. Once this is sorted one question people ask is "How big should I go?".

In very general terms, the larger the turbine the faster the payback. Normally speaking the output increases significantly with the larger output turbines but the £ per kW cost is quite linear.

We offer three sizes of turbine, 2.5kW, 6kW and 15kW. The 6kW turbine will delivery around 3 times more power than the 2.5kw system. and in turn the 15kW turbine will delivery around 3 times more power than the 6kW.

So the more you spend the faster your return should be.

Solar PV Panels - Off Grid or On Grid

2008-06-24T16:11:00.000+01:00

Off Grid On Grid - What does it all mean?

The first thing worth saying is that we are talking about solar photovoltaic (PV) panels and not solar water heating panels.

The term grid refers to the national electricity grid. On grid means that your solar electricity system is connected to the national grid. Off grid means that the national electricity grid is not connected to your solar panel system.

Most people, both commerical and domestic, would talk primerily about on grid applications. The grid is a wonderful thing and there is not usually any sense in disconnecing yourself from it.

However in some cases the grid is not available. This is usually a remote location such as a field with a building in it. In many cases the cost of running the cable from the nearest grid transformer is enormous and the power requirements can be met with an off grid solar photovoltaic electricity system.

This system comprises a set of solar panels, battery conditioner, battery bank and invertor. The batteries give you power when the sun is not shining and the invertor gives you 240V mains electricity.

Roof Integrated solar PV Panels

2008-06-13T14:46:00.000+01:00

Solar Electricity Panels

Solar Electricity (or PhotoVoltaic) panels generate electricity for domestic and commercial use. Panels come in a variety of different shapes and sizes but one question that people have to decide is whether to have the panels mounted on the roof or in the roof.

On Roof Solar Panels

The easier way of retrofitting solar panels is to mount them on top of the existing roof covering. this means that the existing tiles remain in place and the panels sits directly on top. The panels are fixed to the roof joists via special brackets.

Roof integrated Panels (In Roof)

As an alternative to on roof panels the existing tiles can be removed and the panel can be fitted into the roof structure. This leaves the panels almost flush with the existing tiles.

When making a decision as to which is best there are a number of factors to consider. On roof solar panels are easier and quicker to fit. Hence the installation costs are less. However, on roof panels will add additional loading to the roof structure.

Roof integrated panels require the existing roof covering to be removed, this may raise questions with the condition of the felt and battens beneath the tiles, if it is poor it will need rectifying. In roof panels also require expensive flashing sets to make the roof water tight. However, in roof panels aesthetically look better than on roof systems.

Of course if you have a house that has not yet had the roof fitted (new build or new extension) then roof integrated panels are almost certainly the way to go. You will also save some money as less tiles will need to purchased.

Solar Panels - South, East, West or North roof?

2008-06-07T14:43:00.000+01:00

Many people believe that solar panels can only be positioned facing south. This isn't true.

Which direction is best?

South facing at an angle of 35degrees will maximise the output from a solar panel and give all year round best performance.
If the system is to optimised for winter performance then a steeper angle of upto 75 degrees will improve performance. This is because the sun is lower in the sky during winter.

What if I don't have a south facing roof?

If your roof faces roughly south, anywhere between South West to South East at between 30-40 degree will reduce output by a maximum of 10%.

My roof faces East-West?

A 35 degree roof that faces east or west can be utilises but with a couple of system modifications. This type of roof will normally have a reduced output of about 20%, with this knowledge we can oversize the panels to compensate for this reduction in performance.

If roof space is lmited then panels can be fitted on both the east and west roofs. This needs a more sophisticaled pumping station but can have an output similar to a south facing roof without a massive increase in installation cost.

Solar Panels vs Heat Pumps

2008-05-29T14:23:00.004+01:00

Many people don't know which renewable technology is right for them.

In some respects, experts like ourselves can make the decision easier but we thought it would be useful to cover a commonly asked question.

Which is best, Solar Panels or Heat pumps?

Unfortunately it isn't that simple. Solar panels and heat pumps perform different tasks. Solar (water heating) panels use the suns energy to contribute to the heating of your hot water storage cylinder. They cannot however be relied upon to deliver hot water everyday all year round.

Ground source heat pumps on the other hand, extract heat from the ground and use this heat to heat both domestic hot water and your central heating system.

So heat pumps offer a total solution that does not need a backup. They run cost effectively vs most traditional fuels and remove the need for oil tanks or a gas connection.

Solar panels cannot provide this level of reliability.

Solar panels and heat pumps can also be installed to work together. This type of system uses the solar panels to heat your domestic hot water but utilises the heat pump as a back up. This should cut the running costs of the heat pump for domestic hot water by 50-70 per cent.

In roof vs on roof Solar Water Heating Panels

2008-05-17T10:05:00.002+01:00

Solar Water Heating Panels

Solar Water heating panels heat water for domestic and commercial use. Panels come in a variety of different shapes and sizes but one question that people have to decide is whether to have the panels mounted on the roof or in the roof.

On Roof Solar Panels

Roof integrated Panels (In Roof)

As an alternative to on roof panels the existing tiles can be removed and the panel can be fitted into the roof structure. This leaves the panels almost flush with the existing tiles.

Roof integrated panels require the existing roof covering to be removed, this may raise questions with the condition of the felt beneath the tiles, if it is poor it will need rectifying. In roof panels also require expensive flashing sets to make the roof water tight. However, in roof panels aesthetically look better than on roof systems.

It is also worth mentioned evacuated tube solar collectors. This type of solar collector is made up of a number of tubes. Evacuated tubes are almost certainly fitted over the existing roof covering as they are more difficult to make water tight.

£1000 per year for being green

2008-05-15T10:55:00.006+01:00

Save Money and the Planet

Going greener in the High Street and when choosing services and providers could save shoppers anything up to £1,000 a year claims Together. Together is the UK's biggest climate campaign.

The group have published a Savers' Guide, which aims to show how consumers can cut carbon emissions and shave their household bills by thinking more about the environment.

The guide details how an average UK household could cut up to up to three tonnes of CO2 going into their atmosphere.

The simplest of actions are suggested, such as switching to low energy light-bulbs, washing at 30 degrees, installing home insulation, switching to green energy tariffs and not upgrading mobile phones.

For more information contact together.com.

For householders wanting to go a little further they should consider solar water heating, solar electricity panels, ground source heat pumps and wind turbines.

Guaranteed Feed in Tariff on the agenda

2008-04-29T22:21:00.002+01:00

Engineers, trade unions, farmers and house builders today backed a campaign by Friends of the Earth and the Renewable Energy Association to introduce a "feed-in tariff" system that would improve Britain's take-up of renewable energy.

Ahead of a crucial House of Commons vote on Wednesday, which aims to add a feed-in tariff to the energy bill currently going through parliament, organisations such as the Institution of Mechanical Engineers, the House Builders Federation , the TUC and the National Farmer's Union said they wanted to see a feed-in tariff (FIT).

FITs have been introduced in nearly 50 countries around the world, starting with Germany which has massively increased the roll-out of technologies such as solar panels, wind turbines, ground-source heat pumps both at the domestic and industrial levels.

FITs work by setting a guaranteed price for renewable electricity fed into the national grid that is above the market price. The countries which have adopted one have made big carbon savings and created thousands of new jobs. Britain, though, lags behind almost every EU country in its use of renewables, producing just 2% of its energy in this way.

Pop star Lily Allen and her solar-power recording studio, the Premises, have emailed MPs urging them to vote for the measure on Wednesday.

Wind Turbine Electricity and ROCs

2008-04-21T16:00:00.007+01:00

Exported Wind Electricity

Wind Turbines generate electricity that can used in your home or premises.

Excess electricity can be exported back onto the grid and most electricity suppliers will buy this electricity from you.

The rates that are being paid are improving all the time. Many supplier will now a similar amount to the import rate for the electricity you export, currently around 10p/kWhr.

What many people don't know is that in 2002 another parallel scheme was launched that will encourage suppliers to pay an additional amount of money for this electricity.

ROCs

A Renewables Obligation Certificate (ROC) is a green certificate issued to an accredited generator (the home or business owner) for renewable electricity generated. One ROC is issued for each megawatt hour (MWh) of eligible renewable output generated. This means that you get one ROC for each 1000kWhrs of electricity generated.

The scheme is designed to incentivise renewable energy generation in the UK. When the scheme was formulated an obligation was placed on the electricity suppliers to obtain an proportion of their energy from renewable sources. In 2005-06 this target was 5.5 per cent and in 2006-07 the obligation was set at 6.7 per cent.

If the electricity companies do not have enough ROCs they have to pay the other suppliers who do have enough. This means that the suppliers want to buy your ROCs to avoid being penalised.

The payment depends on the supplier but they typically pay around £30-£40 per ROC. This means that every unit of electricity generated is worth about 30-40 per cent more.

The scheme is planned to run until 2027.

This means that Wind Turbines may payback quicker than you think!

The Key to a successful Heat Pump Installation

2008-04-14T09:51:00.003+01:00

Ground Source Heat Pumps

There are many applications for heat pumps, this article is concerned with ground source (geothermal) heat pumps for heating homes and commercial premises.
The primary difference between a ground source heat pump and a conventional boiler is that a conventional boiler is usually designed to heat the property between certain hours. It achieves this by outputting an enormous amount of heat over a short space in time. The property heats up, the boiler switches off and the house goes cold again.

A ground source heat pump works differently to this. The ground source heat pumps does not like producing very hot water. A conventional boiler might out put water to your radiators at a temperature in excess of 70 degrees C. A heat pumps can achieve this but it would be inefficient in doing so.

Therefore the style of heating needs to be changed to accommodate lower temperature heat output.

In general this means using underfloor heating (running at a low temperature, perhaps 38 degrees C) or radiators that are oversized so that they can run at a lower temperature than normal (perhaps 50-55 degrees C).

When the output temperature of the system is lowered it is vital that this heat is retained as the time taken to heat the whole building will increase

The key to a good ground source heat pump installation is insulation. Great insulation will benefit any home, what ever the type of heat system. However, due to the drip feed effect of heating a building more slowly with a heat pump it is even more important that the building retains this heat.

Sadly this means that ground source heat pumps tend not to be the best solution for heating old drafty homes. Having said this barn conversion are often ideal candidates as during the renovation is an ideal time to improve the insulation in the building.

Planning Restrictions on Renewable Energy Installations Loosened

2008-04-05T10:43:00.003+01:00

As of 6th April 2008 the government has amended the planning requirements on a number of renewable energy technologies.

In the future home owners will not need planning permission for renewable technologies such as solar hot water panels, solar electricity panels and ground source heat pumps.

Planners have always looked favorably on renewable technology but these procedures have now been formalised. This will make the decision to purchase environmentally friendly products much easier for home owners.

Note: There are some additional guidelines that can be obtained from your planning authority.

UK Domestic Energy Usage - Hot Water vs Space Heating

2008-04-02T08:57:00.006+01:00

Where does the energy used in our homes go?

This is a useful question when trying to determine payback on technology such as solar water heating panels.

Electricity generated by Solar PhotoVoltaic Panels is fairly simple to determine as this is metered and exported to the national grid at an agreed price. However, when looking at solar water heating panels this calculation becomes more complicated.

Solar water heating panels contribute to your gas or oil bill and it is not immediately obvious how much of your oil or gas is used to heat your hot water vs heating your home.

For this information there is a study that took place in 2005 by the ECI. See graph below.

This graph shows that the vast majority of energy used in our homes is for space heating. However it also shows that, of all the gas used, 31% of it is used to heat hot water. So if you install solar hot water panels and expect to save 50-70% of your hot water heating bill then you can determine that this is likely to reduce your gas bill by between 16 and 22%.

The UK's Going Green

2008-03-29T10:08:00.006Z

Going Green

New research from the Co-op Bank shows that the British public plans to spend more than £13bn to make their homes greener in 2008. Two-thirds claimed they have already taken steps to reduce their carbon footprint in the past year.

The average UK household expects to spend £551.75 on environmentally friendly home improvements. These range from switching to energy-saving light bulbs (60% of those questioned by the bank's researchers), adding loft and cavity wall insulation (40%) and installing double glazing (25%).

The research also shows that householders are even turning to less conventional measures. Green products that used to be rare are becoming the norm, with 11% intending to install rainwater capture systems. 7% are considering the installation of solar panels.

73% of people surveyed in the East Midlands have already taken steps towards having a greener home.

UK Sunlight & Solar Panels

2008-03-27T16:09:00.002Z

Solar Panels

Solar Panels collect the radiation from the sun and convert it into useful Energy such as heat or electricity.

Many people ask us if the UK has enough solar radiation to warrant the installation of solar panels.

The simple answer to this is a resounding yes.

UK Solar Radiation vs The Equator

It surprises many people that in the UK we received around 60% of the solar energy received at the equator. This means that solar panels can make an excellent contribution to heating your hot water or generating your electricity.

The major factor that determines the effectiveness of solar panels is their position. If the panels are facing anywhere between south-west to south-east at any angle between 10 and 50 degrees the panel will achieve over 90% of their potential.
Unfortunately north facing panels are not particularly effective.

More information can be found here about solar water heat panels and further information can be found here about Solar Electricity Panels.

Solar Collectors - Heat Pipe vs Direct Flow

2008-03-19T10:35:00.003Z

Solar Collectors

Solar Collector is the term generally used to describe a device that converts the suns radiation into something more useful, such as heat or electricity. This article concentrates on the solar collectors designed for converting the suns energy into heat which in turn heats your domestic and commercial hot water. Also for this article we are going to ignore flat plate solar panels which you can read about in my other posts. If you are initially researching solar panels you should start by reading the earlier posts in this blog about solar water heating panels.

There are two types of solar collector commonly used in the UK.

- Direct Flow Solar Collectors
- Heat Pipe Solar Collectors

Both systems usually utilise an evacuated tube. This works in a similar way to your double glazing at home. It forms a vacuum barrier that stops heat transferring away from the collector and it stops the cold air cooling the heated liquid down. While this barrier is an effective heat insulator it allows most of the suns radiation to pass through into the absorber surface of the collector.

The difference between direct flow and heat pipe collectors comes when we look at how the heat is transfered from the collector to your hot water cylinder.

Direct Flow Solar Collector

These systems have a loop of pipe that runs through the evacuated tubes. The water that heats your cylinder comes into direct contact with the absorbing surface in each evacuated tube. As this water is heated by the sun it is pumped around the collector tubes and eventually passes through the secondary coil in your hot water cylinder. This secondary coil heats your hot water cylinder.

Heat Pipe Solar Collector

In this system the water does not pass through the evacuated tube, it runs in a manifold at the top of the panel. The evacuated tube contains a rod with a liquid that evaporates at a low temperature. As the liquid evaporates from the suns energy the heat rises to the top of the tube. The top of the pipe connects to a heat exchanger that heats the water in the manifold. The water in the manifold is then pumped through a coil in your storage tank and heats your hot water.

Direct Flow vs Heat Pipe Solar Collectors

Direct Flow is a very simple system that works in a similar fashion to a conventional flat plate collector but with the benefit of vacuum insulation. Some maintenance difficulties may arise if there is a problem with one of the tubes. Removing a single tube can be more demanding as the water pipes are running directly through the tube. However some of the new systems do allow the tube to be slid over the water pipes and removed fairly easily.
Heat pipes on the other hand can be easily disconnected from the manifold and replaced or maintained without fear of damaging water pipes. Heat pipe systems do tend to cost a little more than direct flow systems. Another disadvantage of heat pipes is that they rely on gravity to move the heat to the top of the pipe. This means that they always have to be installed at an angle and cannot be positioned flat against a flat roof. Putting aside the practical installation and maintenance issues the heat pipe collector will function better at lower levels of solar radiation. This is because the heat transfer fluid conducts heat much fast than the directly flowing water system.

Well Water Source vs Ground Source Heat Pump

2008-03-12T19:11:00.006Z

Geothermal Heat Pumps

Geothermal heat pumps, also know as ground source heat pumps, extract heat from the ground using a loop of pipe that runs in the ground outside your property. By reducing the temperature of the ground by a few degrees you can heat your whole house and domestic hot water.

The required heat source can take the form of a closed ground loop or an open water loop.

Closed Ground Loop vs Open Water Loop

In general the most popular form of ground source heat pump arrangement is to have a closed ground loop. However many people in old large houses have access to wells or even lakes.

Water gives up it's heat at a faster rate than the ground because it conducts heat more effectively that soil. This is beneficial to the heat pump system.
Another plus point is that water temperature in wells tends to be fairly consistent, this has a disadvantage in the summer as the ground is often warming than well water but in the winter, when most heat is required, the water is warmer than the ground. This means that the system can run more efficiently in the winter.
Extracting heat from a well also means that there is no ground works are kept to a minimum and the required are of land is drastically reduced.

However, there are also some disadvantages to consider. Extracting water from the ground, in some cases, will need a license. This can be checked with your local council. There is also a significant amount of energy required to pump water from a deep well to the heat exchanger in the heat pump.

One other precaution is that the well needs to have a rapid replenishment rate. This will need to be tested.

If you want to look more into ground/water source heat pumps you can have a survey conducted on your home that will determine it's suitability for you.

Call Intelligent Energy Solutions to discuss your requirements.

Do Wind Turbines payback?

2008-03-06T16:58:00.003Z

Wind Turbines

Wind Turbines utilise the natural wind power to generate electricity. Many size wind turbines are available from a few watts to multi megawatt systems.

At Intelligent Energy Solutions we are interested in micro generation wind turbines for domestic and commercial use. These tend to range in power from 500W up to 50,000W.

Wind Turbine Position

Everyone knows that the windier the position the more electricity is likely to be generated. However not all wind is the same!
The wind that will generate most electricity is 'clean' and free from turbulence. This wind is most likely to occur in open spaces with minimal obstructions.
The wind that blows through our cities is quite different, this tends to disrupted by chimneys, trees and tall buildings.

A good spot for a turbine will be primarily free of obstructions to the South West of the turbine. In the UK the prevailing wind usually comes from this direction.

Wind Turbine Payback

Apart from the siting the turbine in good location, the other important factor is the average wind speed. There is a wind speed database that is free to access and a link to this database can be found at the link, wind speed database.

If the position is free from obstruction to the South-West direction and the average wind speed is in excess of 5m/s then the wind turbine is likely to payback within 10 years.

Solar Water Heating Panels - Flat Plate vs Evacuated Tube

2008-02-29T10:47:00.004Z

Solar Water Heating Panels

Solar water heating panels use the sun's energy to heat hot water for your home. When the water in your roof is hotter than the water in your storage tank a pump is activated and this heat is transferred into your water tank. This type of panel does not generate electricity, click this link to read more about Solar PhotoVoltaic Electricity Panels.

There are two common types of solar collector used in the UK.
- Flat plate collectors
- Evacuated tube collectors

At Intelligent Energy Solutions we offer both types of panel depending on the customers requirements.

Flat plate vs Evacuated tube solar collectors/panels

Evacuated tube solar collectors are typically more efficient than flat plate collectors. This does not necessarily mean that evacuated tubes can produce more hot water just that the panel area can be reduced. Typically you will find that for a flat plate collector area of 4m2, evacuated tubes need approximately 3m2 for the same size hot water tank. With this in mind, the amount of hot water generated throughout the year will be very similar.

An independent study by the DTI compared a number of different types of system and the panel that produced the most hot water was of the flat plate variety.

The cost of the panels are now fairly similar, but some people believe that flat plate solar collectors are more aesthetically pleasing. However, technically the evacuated tubes should perform better than flat plate systems when the ambient temperature is low, i.e. in winter.

So in summary, where roof area is an issue evacuated tubes are the best option. Otherwise, you should consider both evacuated tubes and flat plate collectors.

Intelligent Energy Solutions are happy to fit either type of system as both work very well.

Supermarket Rainwater Harvesting

2008-02-20T21:41:00.004Z

Asda Embrace Rainwater Harvesting

A leading supermarket has announced that it intends on creating more than 9000 jobs through new stores openings and business expansions. Fortunately, they also have an eye on the environment.

This year we will see the opening of ASDA's newest high efficiency store in Merseyside. The town centre store has 40,000 sq ft of space and has cost approximately £16m. The store is built around a timber frame with recycled bricks, recycled aluminium roof and even utilises a rainwater harvesting system. This represents a 50% increase in energy efficiency compared to their typical stores.

For more information about rainwater harvesting systems contact Intelligent Energy Solutions We are based in the East Midlands covering Central England including Nottinghamshire, Derbyshire and Leicestershire.

UK Renewable Energy Success?

2008-02-18T15:50:00.003Z

Government and EU Energy Targets

As we all aware there are many targets set for the UK to reduce our dependency on fossil fuels. Britain has a target to reach 15% of it's energy from renewable sources by 2020. This is provingto be a difficult target seeing as Britain currently generates approximately 2% of it's electricity from renewable sources.

During 2007, Britain installed 270 Solar PhotoVoltaic (PV) systems which is very low when compared to other EU countries such as Germany. In the same year Germany installed around 130,000 systems. This means that Germany currently have more than 200 times more capacity than Britain for generating electricity from solar PV.

I am sure this will all change in the near future as people become more aware of the free energy around their homes and how they can reduce their ever rising fuel bills. Solar Water Heating, Ground Source Heat Pumps and Wind Turbines can all make a big difference. Britain is a fantastic place to live with regard to renewable energy, for example, we have around 40% of Europe's wind!

We also hear rumors of new policies from the government (BERR) that will pave the way for above market payments for electricity exported back onto the grid. These payments will be paid for by other electricity users as this low carbon output of electricity generation will benefit us all.

Roof Mounted Wind Turbines - Is it a good idea?

2008-02-15T16:36:00.006Z

Wind Turbine Installations

Wind turbines have been about for a long time but are only just now becoming accepted by the masses. This has been helped in some way by companies like B&Q stocking them in their store for all to see.
Now they are becoming accepted one question we get asked quite often is...

"Can I mount it on my roof?"

This question isn't as easy to answer as it sounds. In principle the idea of using the height already offered by your property sounds sensible and possibly even cheaper than using a standalone mast.
However in our experience the opposite is true. Using your home to support the turbine poses many complex engineering problems. These problems are not insurmountable but do pose significant difficulties.

Where is the best place for the wind turbine?

In general the installation will not only be cheaper and simpler to use a mast but the system can be more easily positioned away from buildings allowing the system to generate even more electricity. Let's not forget that is supposed to be the whole idea!
Open spaces with minimal obstructions are also a must for the turbine to generate enough electricity to pay for it's self in a reasonable time frame. We simply would not recommend installing a system in a city centre or anywhere with large buildings, tall trees and a generally iratic landscape. While the roof of your inner city home may seem windy this is often turbulent wind that causes a turbine to be confused and unable to establish a good constant speed.

Who should I contact for advice?

Intelligent Energy Solutions are happy to discuss the suitability of your home or premises for a wind turbine. Please feel free to call for a chat about your requirements.

What is Rainwater Harvesting? Domestic vs Commercial Installations

2008-02-06T22:25:00.002Z

What is rainwater harvesting?

Rainwater harvesting is a water conservation system designed to store the rainwater that falls on your roof. The system works by transferring the rain water that is collected by your guttering through a filter and then into to a large storage tank. This storage tank is often buried in the ground next to the property.
This tank typically has an electric pump that pumps the water into your domestic home or commercial premises to be used for your toilets, washing machines and even drinking water.

When the system is correctly specified it can provide around 50% of the annual water requirement for a domestic home.
The benefit of using the rainwater that falls on your roof is that it enables you to reduce your metered water bill and save the energy involved with purifying and pumping of the water delivered by your mains connection.
The code for sustainable homes is also adding additional pressure on developers to utilise this type of equipment.

Who should be interested in rainwater harvesting systems?

The most common use of the stored rainwater is for toilets and washing machines this means that a typical property has a separate cold water system for drinking water and for rainwater. This inevitably means that retrofitting existing properties is often not viable.
On the other hand, self builders and developers are best positioned to utilise this technology as excavation and plumbing works can be integrated into an existing project extremely cost effectively.
Obviously retrofits are still very viable when the property is having it's complete plumbing system replaced or perhaps the conversion of an old barn.

Avid gardeners should also benefit from a rainwater harvesting system as this can help them to keep there garden green all year round, even during a hose pipe ban!

Does rainwater harvesting make sense more for commercial or domestic premises?

Both domestic and commercial properties can benefit from rainwater harvesting systems. However commercial properties often have large roof areas and a high demand for toilet flushing, fleet vehicle washing and site irrigation.
This means that while a domestic installation can provide up to 50% of the water requirements, a commercial property could utilise considerably more rainwater.

Who can supply and/or install a rainwater harvesting system?

Intelligent Energy Solutions can supply and/or install rainwater harvesting systems in domestic and commercial properties.

Why is my Carbon Footprint Important? Can I reduce it and save money?

2008-01-30T22:23:00.003Z

Carbon Crazy?

The words 'Carbon Footprint' seem to have been on everything in 2007. In 2008 it's set to get even bigger.

But, ever wondered exactly what it means for you?

What is a carbon footprint?

A carbon footprint refers to the amount of carbon that a person, company or household produces in a year. Your home is usually the largest contributor to your carbon footprint, on average it is responsible for over 6 tonnes of Co2 emissions each year.

What are Co2 emissions?

Co2 is a gas called carbon dioxide. It is a green house gas that contributes to global warming and defines your carbon footprint. We are all responsible for Co2 emissions in a number of ways, from the exhaust of your car to the coal power station that generates your electricity.

How can I reduce my Carbon footprint?

There are many things we can all do to minimise our personal impact on the environment. This could be as simple as avoiding long haul flights or improving the insulation in your home. Intelligent Energy Solutions install a range of household Co2 reducing technologies, making it as easy as possible for you to make a big difference.
These systems include
- Solar Panels Water Heating and Solar PhotoVoltaic
- Wind Turbines
- Heat Pumps

I've heard these systems are expensive?

No, the benefits outweigh the cost significantly. Fully installed systems start from around £3000. Grants are also available that will cover up to 50% of the installation cost. Not only will such a system reduce your carbon footprint but it will also cut the cost of your energy bills year after year.

Will the installation create a lot of mess?

Many installations will create no mess and no fuss. The installer often only requires access to your property for a day or two.

Why should I bother?

Energy bills are increasing. By installing a system you can significantly reduce your monthly outgoings. Everyday that passes you waste money by not harnessing the free energy that is around us all.
Global warming is not going to go away. Saving the planet is a key government priority. Environmental taxes are already in place, with more to come.

Who should I contact for advice?

Intelligent Energy Solutions is based in the heart of the Charnwood Forest, Leicestershire. From the East Midlands we cover the whole of central England. We are happy to offer free advice and no obligations quotations. Please Call or e-mail for a chat about your needs.

The truth about Geothermal (Ground Source) Heat Pumps - How do they work? Who can install one?

2008-01-24T22:22:00.002Z

Geothermal (Ground Source) Heat Pumps, How do they work?

Ground source heat pumps can be used for central heating and hot water in domestic and commercial premises. The system can completely replace your existing boiler and does not normally need any kind of 3rd party back up system.
Among other things, the system uses a compressor, heat exchanger and ground loop to extract heat from the ground around your house. This heat is then transfered around your house using conventional radiators or underfloor heating etc.

Do I need my own natural hot spring!?

One of the many misunderstandings is that the type of system used in the UK does not need the heat that is stored deep inside the earth. The word Geothermal simple mean earth heat. The systems typically used in the UK extract the heat that is collected by the ground from the sun. It utilises the fact the the earth is one large solar collector.

The clever part is that the heat pump is capable of extracting heat that is perhaps 10 degrees C and 'focusing' it to heat water up to 60 degrees C.

The way this works can be described as being the opposite of a fridge, your fridge extracts heat from a box (or your garden) and emits it using a radiator (your home) on the back of the fridge.

How does it do this?

Well, the ground loop contains a glycol solution that is pumped around your garden and slowly increases it's temperature to that of the ground (this is usually between 7 and 12 degrees C all year round). So, the approximately 10 degree C solution then transfers it's heat to a low pressure refrigerant, once the refrigerant has taken on the relatively small temperature increase, the refrigerant is compressed. At this point the amount the refrigerant is compressed dictates how much heat is emitted. The refrigerant is then de-pressurised and pumped back to the heat exchanger to take the 10 degree heat from the ground loop.

If this doesn't make sense, then don't worry. The system is very reliable, needs very little intervention and will last in excess of 20 years, far longer than a conventional boiler.

Who can install a ground source heat pump for me?

Intelligent Energy Solutions are based in Loughborough, Leicestershire and we are happy to discuss your heat pump requirements. If we think that a heat pump is suitable for you then we will be only too pleased to quote for the supply and/or installation.
Please feel free to call on 01509 891256 or e-mail us to discuss your needs.

Ground Source Heat Pump vs Air Source Heat Pump, which is right for me?

Obviously I have talked only about ground source heat pumps but it is also worth mentioning air source heat pumps.
The difference between these systems is that Air Source Heat pumps do not need a ground loop , they extract heat from the air around us. The disadvantage with an air heat pump is that as the ambient temperature outside decreases the air heat pump struggles to extract heat easily. This means that the efficiency decreases.
One other fact of central heating systems is that you need them most when the outside temperature is at it's lowest. This means that Air heat pumps are useful for heating properties that don't have the room or funds for a ground loop or need heat when the ambient temperature is generally higher. This means that air heat pumps along with unglazed solar water panels are very useful for heating swimming pool water.
In summary if you want to heat your home efficiently with electricity, consider a heat pump. If you have a ground source heat pump you will benefit from good efficiency all year round, where the air heat pump will be significantly less efficient in winter.

What are Solar PhotoVoltaic (PV) Panels? How long to payback?

2008-01-16T22:20:00.010Z

What are Solar PhotoVoltaic Panels?

These panels cleverly convert the suns light into electricity. The cells are usually made up of layers of a semiconductor called Silicon. When exposed to light a DC electrical charge is generated. When numerous cells are banked together they can produce serious amounts of electricity. These cells can be used to power many electrical devices from calculators to your home appliances. The sunnier the position the more electricity that can be generated.

This often, but not always, means positioning the panels on a south facing roof. If the roof is flat the panels can be mounted on frames that hold the panels at the optimum angle.

When connected to the national grid a property can benefit from reduced electricity bills and can even export electricity to the national grid.

The panels tend to cost somewhere between £5k to £7k per kW.

Are Solar PV panels right for my property?

If specified properly, installing Solar PV WILL reduce your electricty bills. For roof mounted panels, having a south facing roof is useful. However, depending on the roof angle panels can function properly facing South West to South East. They still benefit from 95% of the suns radiation.

The panels can be sized in a number of ways, one method is to geat the capacity to the minimum load on the property, so if the property typically uses 1kW, install 1kW of panels. This means that on the sunniest day every bit of electricity being generated is being used. Alternatively, you can install a much larger capacity and sell the excess electricity back to the national grid. The rates the electricity companies will pay for this electricity is now starting to become more competitive.

Will this type of solar panel pay for itself?

This answer to this question depends heavily on way you measure payback. The environmental payback is extremely quick, perhaps even 6 months? With regard to financial payback the calculation becomes more complex, let's assume the following:-

- Electricity prices continues to rise as they have over recent years.

- The system adds 50% of it's installation cost to your homes value.

- You take a rebate from the electricity company for exporting spare electricity

Given these, not unreasonable, assumptions, a system could payback within 12 years. After 20 years the system would have paid for it's self twice over.

Some companies offer incredibly sort payback periods, be wary of this as their maths is often questionable.

Who will install Solar Panels for me?

Please contact Intelligent Energy Solutions, we will be happy to discuss your requirements in an open and honest manor. Given the fact that we also offer geothermal (ground source) heat pumps, wind turbines and solar water heating panels, we will recommend the most appropriate technology for you.

What are Solar Water Heating Panels? Where can I get them?

2008-01-09T22:18:00.001Z

Confused about Solar?
Many people who call me seem to be a little confused as to how solar panels actually work. My view is that the misunderstanding is perfectly reasonable and stems from the general acceptance of solar panels on things like calculators or garden lamps.
These types of solar panels are called photovoltaic solar panels or PV Solar Panels and I will talk about these in more detail another week.
For now I think I should explain about the panels that people are less familiar with but give the greatest opportunity to reduce household fuel costs. These panels are called Solar Water Heating Panels.

Solar Water Heating Panels
Solar Water Heating Panels use the suns radiation to heat water in panels. This panel is connected to your hot water storage tank. When the temperature in your tank is lower than that of the panel on your roof the water is pumped out of the roof panel through a heating coil in your hot water tank. This heats the water in your storage tank. When is is cold and dull outside the pumps leaves the cold water in the roof panel and your storage tank is heating with your conventional boiler.
This simple but effective system is typically capable of heating up to 70% of your annual requirement for domestic hot water.
Given this fact it is probably the most cost effective and way of installing a renewable energy system in your home.

Where do I get this type of Solar Panels?

Well, thats the easy bit. Contact Intelligent Energy Solutions by phone or e-mail and we will be happy to discuss your requirements and if required arrange a meeting.

I hope you find this blog useful.

NPower Gas and Electricity Price Rise

2008-01-04T21:42:00.000Z

Npower has announced that electricity prices for its domestic customers will rise by 12.7%, while gas bills will see a 17.2% increase.
Npower, the UK's fourth-largest energy provider, said it had been "forced to put up prices" because of soaring wholesale energy costs. It said it expected rival energy providers to follow suit with their own price rises "very shortly".
