The rim of an electric radiant heater is formed by a multilayer body (13). It can have the cross-sectional shape of a U, whose interior is filled with a good insulating material. In the interior (23) is placed a sensor coil (23) for a pot detection system, where it is well shielded against heat and mechanical influences.

Electric radiant heater

A radiant heater with partly embedded and otherwise projecting heating coils (16) is produced in that the coils (16) are placed in grooves (14) of a tool or mould (13), the interior of the heating coils is partly filled with a filling material (17) and then the dry, pourable insulating material is pressed thereon. Thus, the filling material forms a counter-die and is removed on taking the compressed insulator (21) out of apparatus (11) in that it drops between the heating coils.
