LIQUID ELECTRIC HEATER Russian patent published in 2019 - IPC H05B6/10 

FIELD: heating.

SUBSTANCE: electric liquid heater can be used for heating of water, oil, liquid with low freezing temperature in boiler and heating systems. Electric liquid heater includes a liquid-filled vessel with pipes for supply and discharge of cold and heated liquid streams, electric heating elements, an alternating current source, connecting current and zero conductors arranged in the vessel, transformer with a ferromagnetic frame consisting of magnetic flux primary excitation cores connected by crosspieces cores and increasing voltage, as well as with current conducting windings of primary excitation of magnetic flow and increased voltage from insulated wires, arranged on said cores respectively, wherein the conductive current winding of the primary magnetic field excitation is connected by current and neutral wires to an alternating current source, and the conductive current conductive winding of the voltage rise is connected to electric heating elements of the liquid electric heater, wherein the transformer carcass comprises an additional ferromagnetic core with an additional current-carrying winding placed on it from the insulated wire, which is connected by its additional current and neutral wires to the AC source and the current-conducting winding of the primary excitation of the magnetic flux.

EFFECT: this invention implements the effect of considerable reduction of power consumption.
