Abstract
An electrical heating element for a radiant electric heater takes the form of an elongate electrically conductive strip for partial embedding edgewise in a base of thermal and electrical insulation material. The strip is composed of an elongate continuous portion and an elongate discontinuous portion integral with the continuous portion. The discontinuous portion is intended for embedding in the base and is provided with a plurality of discontinuities so that in operation of the heater current flow in the discontinuous portion is reduced or eliminated.
