heat power industry. SUBSTANCE: invention is related to heating facilities transforming electric energy to thermal energy. It can be used to heat up rooms by local heating systems filled with liquid heat transfer agents. Proposed heater includes body with tubular element, main and two additional phase electrodes installed in turn inside body and uniaxially to it. Each electrode has tubular element which diameter differs from diameter of other tubular elements. When installed in body it forms together with tubular element of body circular clearance of specified value which makes it feasible to vary heat power of heater simply and efficiently. EFFECT: capability to vary heat power of heater simply and efficiently. 2 dwg
