FIELD: heating engineering, particularly liquid heating equipment.
SUBSTANCE: liquid heating device comprises heat-generator having outlet pipe, electrically driven main-line pump connected to heat-generator, supply and return pipelines provided with shutoff valves, which establish heat-generator communication with heat-exchangers. Heat-insulated sealed heat-exchanger is arranged between outlet pipe and supply pipeline. The heat-exchanger has turbine communicated with electric drive. Outlet heat-generator pipe is made as converging nozzle provided with curvilinear grooves in inner surface thereof. The curvilinear grooves extend from inlet orifice to outlet one in longitudinal direction.
EFFECT: increased energy-conversion efficiency.
