Solar installations transform the energy of solar radiation into utility heat. The heat, extracted in solar collectors, is transferred through the heat-transfer medium into a tank for utility where it is accumulated. The efficient operation of the system is provided by a temperature difference controller which functions with a circulating pump.
An excellent absorber, a perfect construction of casing, as well as a very good thermal insulation of the collector allows it to achieve very high efficiency of operation both in summer and winter.
