A heating element assembly having a thermally conductive ceramic top sheet against the underside of which is positioned a thermally and electrically insulating base pod having a recess containing a loosely secured, planar array of thin, flat strips of apertured, foil-like, electrical resistance material. The array is spaced from the ceramic sheet a predetermined distance and disposed in such a manner as to provide a large amount of heat radiating surface adjacent to the underside of the ceramic top. The spacing between the array and the ceramic top sheet enhances even radiant heating of the ceramic top. Such a heating element assembly is low in cost and high in thermal efficiency, having particular utility as a burner for a ceramic top electric range. |
