Solar Water Heating

Solar water heating systems, or 'solar thermal' systems, use free heat from the sun to warm domestic hot water using a solar thermal collector.


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

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.

Types of solar heater

FPC (Flat plate collector)

The solar radiation is absorbed by Flat Plate Collectors which consist of an insulated outer metallic box covered on the top with glass sheet. Inside there are blackened metallic absorber (selectively coated) sheets with built in channels or riser tubes to carry water. The absorber absorbs the solar radiation and transfers the heat to the flowing water.
