Abstract

An electric boiler device based on utilization of residual energy of an elevator includes a heat storage module, an electric heating module and a control module. A heat storage water tank of the heat storage module is replenished with water from a tap water pipe network, and a preheating unit of the heat storage module converts the residual energy of the elevator into heat energy of the heat storage water tank by using an energy consumption resistor. The control module replenishes a heating water tank with water by delivering preheated water to the electric heating module according to a water level of the heating water tank, and controls a heating unit of the electric heat module to heat the heating water tank according to a user-set temperature, and heated hot water is provided through a user water supply pipe network.
