PURPOSE: An electric boiler is provided to maximize the efficiency of energy consumption by heating water in a short time and to perform super power saving operation by realizing heating with minimum power consumption. CONSTITUTION: An electric boiler comprises a boiler(100), unit boilers(200) and a heating water flow path(300). In the boiler, a high temperature water outlet line(110) is placed in the upper side while a low temperature water recovery line(120) is placed in the lower side. The unit boiler is placed between the outlet line and the recovery line. A heater(210) and a heat medium(220) are charged in a vacuum condition in the unit boiler. The heating water flow path is formed in between the faces of the unit boilers to let the heating water exchange heat. For extending the heat exchange path of the heating water, a guide flow plate(310) is placed in the heating water flow path. The guide flow plate guides the zigzag flow of the heating water. Therefore, efficient and power-saving heating is realized.
