Heat water for your home using energy from the sun
Solar water heating systems use free heat from the sun to warm domestic hot water. A conventional boiler or immersion heater can be used to make the water hotter, or to provide hot water when solar energy is unavailable.
The benefits of solar water heating
- Hot water throughout the year: the system works all year round, though you’ll need to heat the water further with a boiler or immersion heater during the winter months.
- Cut your bills: sunlight is free, so once you’ve paid for the initial installation your hot water costs will be reduced.
- Cut your carbon footprint: solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions.
How do solar water heating systems work?
Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to heat up water which is stored in a hot water cylinder. A boiler or immersion heater can be used as a back up to heat the water further to reach the temperature you want.
There are two types of solar water heating panels:
- evacuated tubes
- flat plate collectors, which can be fixed on the roof tiles or integrated into the roof.
Larger solar panels can also be arranged to provide some contribution to heating your home as well. However, the amount of heat provided is generally very small and it is not normally considered worth while.
The cost of installing a typical solar water heating system is around £3,000 to £5,000 (including VAT at 5%). Savings are moderate – the system could provide most of your hot water in the summer, but much less during colder weather.
Solar water heating systems can achieve savings on your energy bills. Based on the results of our recent field trial, typical savings from a well-installed and properly used system are £60 per year when replacing gas heating and £70 per year when replacing electric immersion heating; however, savings will vary from user to user.
You may be able to receive payments for the heat you generate from a solar water heating system through the government’s Renewable Heat Incentive.
From August 2011, you may be able to get help with the installation costs of a new solar water heating system through the Renewable Heat Premium Payment scheme, payments will vary according to the number of people living in the property.
Green Deal finance and renewables
This technology is an eligible measure under the UK government’s Green Deal which is a financing mechanism that lets people pay for energy-efficiency improvements through savings on their energy bills. Call us about solar panels Wigan and surrounding area enquiries.
