What is Solar Thermal?
Solar thermal is a clean and highly efficient process by which energy from the sun is used to heat up water for use in the home.
- Save money on your hot water bills. An average system will provide 50% of your annual hot water needs.
- Cut your carbon dioxide emissions
- Receive a guaranteed income through the governments Renewable Heat Incentive (RHI) scheme.
How it Works
It’s a simple process:
Panels, known as Solar Collectors are attached to your roof. These collectors capture heat from natural sunlight and transfer it to a special glycol/water solution contained inside them.
When the solution has reached the required temperature, a pump station circulates the hot fluid through a coil into the water cylinder. This enables the heat captured to be transferred to the water in the cylinder, which can then be used in your home. (The pump station itself is small so it can easily be fitted discretely in your property, for example, within an airing cupboard. )
A sensor in the cylinder monitors the temperature of the water and if it doesn’t reach 60oC (or the set temperature) the boiler or immersion heater will fire up to supplement the system.
There are two main types of collectors, Flat Plate or Evacuated Tubes. Both have their own advantages – flat plates are generally considered to be more aesthetically pleasing and are constructed of minimal components, whilst evacuated tubes are slightly more expensive but are more efficient.
