Solar Water Heating uses the radiation from the sun to heat water in a panel often sited on the roof which in turn can supply that heat as hot water or to a central heating system. Unfortunately the demands on your central heating system are at their highest when the sun is weakest so a solar heating system will only contribute to part of your heating energy requirements.

If the system has been sized correctly, it can provide at least 40-60% of all your hot water requirements throughout the year. The average domestic system reduces carbon dioxide emissions by around 400kg per year. Solar panels should be sited on a south-facing pitched roof, free of shade, at an angle of between 20 and 50 degrees, or may be mounted on an angled frame on the ground or on a flat roof. The typical domestic installation requires 2 – 5 square metres of roof area and you may also need space to locate an additional water cylinder.
