Solar Thermal Heating

Solar Thermal Heating is a way to capture solar energy directly from the sun. Naturally heating water and helping provide hot water demands in your home, property or business.

Why should I invest in solar thermal heating?

One selling point is that sunlight is free. So although you have an initial outlay for installation your hot water bills will be significantly reduced.

Solar Thermal Heating provides hot water throughout the year so even on cold days when the sun is still shining, hot water can still be produced.

All Solar Thermal installations are covered under the UK Government’s Renewable Heat Incentive Scheme so you can earn an extra income too.

How it works

Solar thermal works in a similar way to leaving a hosepipe out on the floor in the sun. It generates 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 transfers its heat into the hot water through the heat exchanger and the hot water in the thermal store is ready for whenever you need it, weather that be for domestic hot water or a boost on your heating.

When the water within the thermal store falls below a set temperature the pump simply starts up and the process is repeated again.

Benefits of solar thermal heating

Lower installation cost than typical solar PV for same KW production
Works all year round
Extremely low maintenance
Fully automated
Excellent as a link in system to high efficiency boiler or Air Source Heat Pump
