An apparatus for rapidly heating a cooktop is provided. The apparatus comprises a radiant heating element positioned proximate to the cooktop. A controller is provided and is connected to the radiant heating element. The controller includes a fast heat-up circuit selectively coupled to the radiant heating element. A look-up table is selectively coupled to the fast heat-up circuit. The look-up table comprises a plurality of user power levels. Each of the plurality of user power levels is correlated to a respective user-selected temperature. The apparatus further comprises a user power input device connected to the controller. The user power input device also allows selection of at least a first of the plurality of user power levels wherein the first power level corresponds to a first respective user selected temperature in the look-up table. A temperature sensor is connected to the controller for measuring a temperature of the cooktop.
