About solar systems

Water heating by solar collectors is a typical example of usage of the solar thermal energy. The system is relatively simple, effective and reliable. Existing experience that properly designed high-quality equipment can reduce annual hot water expenses by 70 %. Solar heating systems developed on the basis of modern technologies can have efficiency up to 80 %. The solar heating system is controlled by a regulator that switches a pump unit, which depends on a temperature difference between the solar collectors and the hot water storage tank. Auxiliary hot water heating, if necessary, in all types is carried out by the heating unit, and in the NTRR type it is carried out by the top exchanger‘s.
