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.
