Abstract
An electrical radiation heater for a glass ceramic plate, which serves as a cooking plate, comprises an electrical heating strip mounted on an insulating sheet. The heating strip is slit alternately from opposite edges to give it a zig-zag shape and is bent or curved so that it undulates in serpentine fashion. The strip is laid edge-on onto the insulating sheet and anchoring tabs integral with the strip penetrate the insulating sheet. The insulating sheet is laid on an insulating layer which is received in a flat bottomed supporting dish or tray and which is made from a good thermally insulating as well as electrically insulating material.
