FIELD: heating and feeding fluid media, air for example. SUBSTANCE: electric heater has rotation drive which is connected with movable unit for supply of medium with working members and electric heating elements built in medium supply unit; they are used as working members; electric heating elements are made in form of monolithic housing, ceramic, for example with electric current conductor mounted in housing. When drive is switched on and electric power is fed, electric heating elements move at high speed relative to medium, thus providing for intensive heat removal depending on this speed. EFFECT: enhanced efficiency. 2 cl, 1 dwg
