How does a solar thermal hot water system work?
A solar thermal hot water system collects heat from the sun and uses it to heat the hot water in your hot water storage tank. This hot water is then supplied to the taps and showers in your existing hot water system.
The main parts of a solar thermal system are the collector, made up of either evacuated tubes or flat panels which go on your roof, and a twin-coil hot water tank.
As the water heated by the solar thermal panels needs to be stored, you’ll need a heating system with a hot water tank.
