The plug-and-play capacity-free power carrier electric heater according to claim 7, wherein if it is determined that the received user house-entry electric power exceeds the house-entry electric warning power, the power supply to the heating element is temporarily cut off according to the priority level of the room; when the household electricity has idle power and the room temperature does not reach the set temperature, supplying power to the heating element to control the heating element to start heating; and if the room temperature does not reach the set temperature but the idle power is less than the heating power of the room, controlling the heating body to be in a heating waiting state and incapable of heating.
9. The plug-and-play capacity-free power carrier electric heater according to claim 7, wherein if the received real-time branch power is judged to exceed the corresponding branch pre-warning power, the power supply to the heating element is temporarily cut off according to the sequence of the access; when the branch circuit has idle power and the room temperature does not reach the set temperature, power is supplied to the heating element to control the heating element to start heating; if the branch power does not reach the heating power of the electric heater, the heating body is controlled to be in a waiting heating state, and heating cannot be carried out.
