ABSTRACT:
An electrical heating assembly (2) comprises a glass-ceramic cooking plate (4) having an upper surface (6) for receiving a cooking vessel (8) and a lower surface (10). A radiant electric heater (12) incorporating at least one electric heating element (20) is supported in contact with the lower surface of the cooking plate. Temperature sensing means (29) is spaced above the at least one heating element (20). The temperature sensing means includes a support member (33) which has provided on an upper surface a film form temperature-sensitive electrical resistance element (30) and which is provided with electrical connecting leads (34). Thermal insulation means (40) is adapted and arranged to shield the support member (33) and a corresponding region of the lower surface (10) of the cooking plate (4) from direct thermal radiation from the at least one electric heating element (20).
