ABSTRACT:
A heating unit (H) for a cook top includes a thin and relatively fragile resistive heating element like, but not necessarily limited to, a ribbon (E). The heating element is mounted on the upper surface of a cake (I) of microporous insulation material. The heating element is arranged in a predetermined pattern on the material and a plurality of staples (10) are used to attach and hold the heating element on the material surface. Each staple is a glass staple and the staples are spaced along the length of the heating element to mount the heating element to the insulation. The staples are electrically non-conductive and do not create heat sinks at their locations of use. Thus, they do not affect the efficiency of heat transfer between the heating element and that which is being heated. The staples are also of a glass material which can withstand high temperatures and numerous temperature cycles to provide a long service life.
