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.

Costs, savings and earnings

The cost of installing a typical solar water heating system is around £4,800 (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.

Maintenance

Maintenance costs are very low. Most solar water heating systems come with a five-year or ten-year warranty and require little maintenance. You should take a look at your panels every year and have them checked more thoroughly by an accredited installer every 3-5 years, or as specified by your installer.

Savings

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 £55 per year when replacing gas heating and £80 per year when replacing electric immersion heating; however, savings will vary from user to user.

Typical carbon savings are around 230kgCO2/year when replacing gas and 510kgCO2/year when replacing electric immersion heating.

Earnings

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. This scheme should be launched in October 2012.

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.

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.

Wind Turbines

If you have the space to install. It makes sense to harness the full potential of wind power. Wind power is free and the feed in tariff means the cost is soon recovered as these systems can run 24hrs a day.
