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.
