Abstract

A flat bearing coating (7) for the heating coil (5) of a heating device is formed from an inorganic mass with a binding agent and fillers, especially based on silica sol with a fibre additive. The mass for the bearing coating (7) is applied moist onto a substrate or directly onto an insulating coating (2), and the heating coil (5) is pressed into the still moist mass to a depth between a half and a complete wire thickness of the coil wire. In this way, each lower curved section of the heating coil is held individually in the hardening (and, if required, ceramising) material of the bearing coating. In this manner, any opposing movements of the coil sections, which could lead to a short-circuit, are reliably prevented and, nevertheless, a maximum useful radiation is ensured. The production is simple and allows great flexibility with respect to a step-by-step prefabrication. <IMAGE>
