Abstract

Resistance heating coils (14, 16 etc.), flattened longitudinally along two sides to have generally oval cross- sections, are totally embedded in situ in a lightweight ceramic fibre insulating body (31) so that one flat side extends generally along the surface of the insulating body. Electrical terminal elements (40, 42) extend from the heating coils (14, 16) through the insulating body (31), and axial movement of the terminals is prevented by anchoring ribbons (50) welded thereto. In one embodiment, the coils are embedded in an insulating body having a thickness no greater than about twice the depth of the heating coils. The resulting compact heating unit is sufficiently thin to be mounted as a replacement unit on the interior walls of an existing furnace. <IMAGE>
