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 in colder months.
Reduced bills: Sunlight is free, so once you've paid for the initial installation your hot water costs will be reduced.
Reduced carbon footprint: Solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions.
