Abstract
In an electrical heating apparatus having at least one heating body with a chemically substantially resistant sheathing surrounding same, the sheathing comprises at least two-layer co-extruded material. The material comprises an inner layer which in the position of use is towards the heating body and which comprises a material that is a good conductor of heat. Arranged on the outside of the inner layer is an outer layer of chemically substantially resistant and electrically non-conductive material. The inner layer and the outer layer are homogeneously fused together without air inclusions.
