A method for producing a surface heater for heating a sub-region of a vehicle includes a first step, a second step, a third step, and a fourth step. The first step includes arranging heating wires on a film and either: i) the film is subsequently formed to a predefined shape, or ii) providing a film which has been formed to a predefined shape. The second step includes inserting the formed film into an injection-molding tool. The heating wires point either toward the wall or into the hollow space of the injection-molding tool. The third step includes overmolding with a predefined material. The fourth step includes applying a transparent lacquer layer to the finished injection-molded part.

An electric resistance radiant furnace is disclosed. Solid ceramic panel emitters having electric resistance wires embedded therein produce heat. A blower receives air from a return duct. Metallic screens are located between the panel emitters. A thermostat is connected to the wires and the blower. Heat is produced by each panel emitter. Part of the heat produced is radiated from the ceramic body to the metallic screens. Air flows in a parallel manner between the panel emitters and along the metallic-screens. The thermostat heat buildup by turning on the panel emitters controlling the blower. A short cycle air pass conduit accepts a portion of heated air from between the multiple panel emitters and to convey the portion of heated air to the return duct, such that the portion of heated air is mixed with return air, and a temperature of the return air provided to the blower is elevated.
