ABSTRACT:
An electric radiant heater unit for a glass ceramic top cooker comprises two independently energizable heater elements supported on a base of electrical and thermal insulation material. A thermal cut-out device, which may be of the differential expansion type, extends from a peripheral wall of the unit across one element and across a zone normally occupied by at least a part of the other element. However, that zone of the heater unit heated by said one element is extended to influence substantially the entire effective length of the cut-out device, that is including that portion of the cut-out device which extends across the zone normally occupied by at least a part of the other element.
