PURPOSE: An electric steam heating device of high efficiency, capable of stable steam supply, is provided to increase heating efficiency by consecutively generating lower steam while maintaining the uniform level of a heating chamber. CONSTITUTION: An electric steam heating device of high efficiency comprises a steam generator(10), a radiator(20), a blower(25), a condensate receiver tank(30), and a condensation supply pump(40). The steam generator comprises a heating chamber, an electric heater, a plurality of water level sensors, and a bubble blocking member. The electric heater heats the water of the heating chamber using external electricity energy. The bottom parts of the water level sensors are arranged in different height and sense water level. The bubble blocking member prevents the contacting between the water level sensor and the bubble which generated by the electric heater. The blower blows air using a radiator and sends the air to a fixed area after heat exchange. The condensation supply pump supplies the condensation to the steam generator from the condensate receiver tank.
