ABSTRACT:
An electric heating device is provided by the use of an electrical conductor or resistance element which is formed in the shape of a cable harness and encased in a polymer cement block. The conductor can be metal, alloy, or carbon fibre and the cement block, which has good electrical insulating and good heat conducting properties, is composed of approximately 75%-95% by weight of inorganic or mineral filler and 5%-25% of a polymer or plastics material. The electrical element is wound in harness form so that the required wattage is dissipated within the block without the requirement of any type of thermostatic control. Further by the selection of pigments and various combinations of mineral or inorganic material, heating devices can be produced having any desired size, shape or decorative texture.
