ABSTRACT:
An energy regulator for a household heating appliance such as an electric cooker comprises an electronic controller for the cyclical control of the supply of electrical energy to a heating element and a switch for increasing the electrical energy supplied to the heating element to a preselected level and for a preselected time. The preselected time may be variable in dependence on the duty cycle of the controller, the duration decreasing from about thirteen minutes at low duty cycle to one minute or less at high duty cycle. Actuation of the switch may cause the electrical energy to be increased to substantially 30% of full heating power at low duty cycle rising to substantially 100% of full heating power at high duty cycle.
