ABSTRACT:
An electric heater for a glass ceramic top cooker includes a base layer of thermal insulation material such as ceramic fiber or a microporous thermal insulation, a source of infra-red radiation such as a pair of infra-red lamps, and a reflector which is positioned so as to reflect infra-red radiation emitted by the source towards the layer of thermal insulation material. The reflector may be a specular reflector such as a coating of a reflecting metal deposited internally or externally of the source of infra-red radiation or may be a diffuse reflector such as a layer of fine particulate alumina deposited onto the external surface of the source of infra-red radiation.
