SUBSTANCE: invention relates to the field of heat power engineering and may be used to provide hot water supply and heating of buildings and structures located in areas with no centralised heat and power supply. A thermal wind turbine comprises a rotor wind engine with a vertical shaft, which transmits rotary motion via a reducer to a round plate, to which vertical cylindrical partitions are fixed at the bottom, being submerged into a heat insulated tank with water. Cylindrical partitions are also fixed to the bottom of the tank, and partitions fixed on the round plate move between those. Water arriving into the tank, flowing via movable (rotary) and fixed partitions is heated due to friction. Since the gap between movable and fixed partitions is chosen as minimum possible for water passage, water heating is carried out quite effectively, which is also supported by a roll arranged in the form of a net increasing friction made on the surfaces of cylindrical partitions. Blades mounted on the outer side of the external (relative to the central axis) movable (rotary) cylindrical partition help to pump water into the outlet nozzle of the tank and back to the load.
