FIELD: heating and water supply systems. SUBSTANCE: device has induction heater incorporating magnetic-circuit cylindrical shell with inlet and outlet pipe connections, external and internal inductance coils, cylindrical and circular liquid-flow distributors, insulating gaskets, and magnetic-circuit screen. Heating temperature is controlled by means of ac rectifier and inverter interconnected in series and connected to induction heater. Inverter is also connected to its respective control unit, temperature comparison unit connected to temperature sensors, pump control unit, and pump. Water is heated due to heat transfer from walls of cylindrical magnetic-circuit shell, which are heated, in their turn, by eddy currents induced by coils, to thin layers of cold liquid separated by set of flow distributors. EFFECT: improved power factor and efficiency of device, increased speed and economic efficiency of water heating. 3 cl, 3 dwg
