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.
