ABSTRACT:
A storage heater of the kind which is heated from a source of electricity made available only over an off-peak (low tariff) period, and of the kind which does not require a supply of power during operation outside the off-peak period. The heater comprises a body, a heat store within the body, electrical heating means for the store, air passages extending through the store from an inlet to an outlet, through which air is caused to flow in the operation of the heater solely by convective pressure, and a flow control damper or flap mounted adjacent to the outlet for controlling flow of air from the heater. The heater additionally comprises an operating means to control the flow control damper, said operating means comprising a first thermo-responsive device mounted at a position at which it is primarily responsive to the temperature of the store, and a second thermo-responsive device mounted at a position where it is traversed by air flowing through the inlet into the heater, the combined functional output of the thermo-responsive devices determining the position of the flow control damper. In this manner, operation of the flow control damper is dependent both on the heater core temperature and on the air temperature of the room in which the device is operating.
