“Liquid regenerative electric boiler” is a new type of heat source which uses off-peak power or abandoned wind power to adopt liquid heat storage. The working voltage of this equipment is 380V, so it is necessary to build a substation. At present, most electric boilers used in heating system are resistance-type, that is, electric heating elements adopt electric heat pipe. There is also electromagnetic type, semiconductor type; On the basis of electric boiler, heat storage device is added, which is called regenerative electric boiler. The regenerative electric boiler is composed of an electric boiler body (including an electric control cabinet), a heat-preservation-type heat storage device, a circulating pump, and a water treatment device, etc.
Regenerative electric boiler takes the electric boiler as the heat source, takes advantage of cheap electricity at night, uses water as the heat storage medium for heating, and stores it in the heat storage tank.

"High-power electric regenerative boiler” is a new type of high-power heat source that adopts solid heat storage mode by using off-peak power or abandoned wind power. he equipment does not need a transformer, and can work directly under the voltage level of 380V to 110KV, realizing the super-power electro-thermal conversion and super-capacity thermal energy storage.
