How does Solar Thermal Heating work?
Solar thermal works in a similar way to leaving a hosepipe out in the sun. It generates renewable heated water using a flat plate solar panel called a collector that is fitted to the side of your roof. Inside the collectors are coils of copper pipe which, when you add sunshine, heat up the water that is slowly moving inside them.
There is a transfer fluid that we push through the pipes and once this reaches the required temperature it is pumped into a heat exchanger within a large storage tank (we call this a thermal store). This ‘transfer fluid’ then literally transfers its heat into the hot water through the heat exchanger and the hot water that we all know and love stays in the thermal store ready for whenever you need it.
When the water within the thermal store falls below a set temperature the pump simply starts up and the process is repeated again.
