Abstract
Heating apparatus consists of a shallow circular tray having a layer of thermally insulative material disposed therewithin and supporting four infra-red-emitting, tunsten-halogen lamps on flanges. A moulding of ceramic fibre material is press-fitted around the ends of the lamps and a thermal limiter is provided to limit the operating temperature of the apparatus. Each lamp is provided with a reflective coating along the lower part thereof, so as to reflect upwardly infra-red radiation emitted in a downward direction. A number, preferably four, of the heating apparatuses are disposed beneath a layer of glass ceramic to provide a cooking hob.
