Solar Thermal Systems consist of solar panels (or collectors) fitted to your roof and work in conjunction with a hot water cylinder. The solar panels collect heat from the sun and use it to warm the water which is stored in the cylinder.

There are two types of solar water heating panels, they are evacuated tubes and flat plate collectors. Evacuated tubes are the more efficient technology (shown in the picture above).

The solar system works hand in hand with your boiler. In winter the solar panels will take  the water temperature up to 45 degrees with your boiler taking the water from 45 - 60 degrees.

In Summer the solar panels will heat the water without the use of the boiler. Solar thermal panels need a shade free roof facing South East to South West, with South being the premium orientation. Solar thermal can also be installed onto flat roofs or be ground mounted.

A well sited, efficient Solar Thermal system will provide you with approximately 70% of your annual hot water needs. The other 30% will be provided by the boiler in the traditional manner.

If you do not already have a hot water cylinder, then you will need to install one  with a solar heating coil.

The introduction of the Renewable Heat Incentive (RHI) in April 2011 means that you will receive a return of approximately 8% per annum on an investment in a Solar Thermal system.

A typical installation will cost approximately £4000, therefore the return on investment would be approximately £320, made up of income from the RHI and energy savings.

This system would save approximately half a tonne of Co2 being released into the atmosphere per annum.
