The solar thermal installation is designed for hot water production, for domestic needs and heating. It is characteristic for its increased utilization rate of direct sunlight, improved heat capacityand heat output of the heat accumulator and comfortable maintenance of a constant level of cleanness of the sunlight transparent surface of the solar thermal collector (A). The solar thermal collector (A) has linear concentrators (24) to capture, concentrate and transform the direct sunlight into heat on thermal pipes (25) and a device (C) is maintaining, by programmable automatic washing, the permanent level of cleanness of the transparent cover (26) of the solar thermal collector (A). The heat accumulator (B) consists of an inner reservoir (1), filled with a fluid û a heat-transfer agent oftemperature up to 120 ? C and operating pressure Pa up to 3,5.105 and external reservoir (7) divided into sections filled-up with latent accumulating substances.
