Because the wall body, the floor, the indoor air, objects and the like of the heating building have heat storage functions, the indoor temperature change is small under the condition of normal use, and the hysteresis is certain, the electric heating is not an emergency electricity utilization condition, and the heating is possible by adopting intermittent heating.
