solar heating Benennung

DefGEMET: A domestic or industrial heating system that makes direct use of solar energy. The simplest form consists of a collector through which a fluid is pumped. The circuit also contains some form of heat storage tank and an alternative energy source to provide energy when the sun is not shining. The collector usually consists of a black surface through which water is piped, the black surface being enclosed behind glass sheets to make use of the greenhouse effect. (Source: UVAROV)
