Electrical heating apparatus (10) is used in an electric stove (R) having a glass/ceramic cooking surface (S). A pan (12) is mounted adjacent an underside of the cooking surface. An electrical heating element (20) installed in the pan heats a defined area (A) of the cooking surface when electrical current is applied to the element. A sensor (34) installed in direct contact with the cooking surface senses the temperature of the cooking area. A control unit (42), to which an output of the sensor is supplied, is responsive to the output to control current flow to the heating element. This allows the apparatus to respond to temperature changes at the cooking area to insure food is properly cooked.
