Abstract: Electric heating apparatus having at least one electrical heating resistor (24) arranged in a body (1) of sheet metal provided with an air inlet in its lower part and an air outlet in its upper part. The body (1) is formed by a double-walled hollow element in the form of a trough (2, 3) provided with end walls (14, 15) and at least one opening (12) for the entry of air and defining a first space (20) for the admission of air. The electrical resistor (24) is mounted on the concave part of the double-walled element in the form of a trough (2, 3) on the exterior of the latter. A perforated panel (30) is arranged on the concave wall and defines with the latter a second space (33) for the heating of the air by convection and for the direct radiation of the heat by the resistor through the perforations in the perforated panel.

Abstract: A temperature regulating device for electric heating apparatus has a thermostat for controlling the operation of the apparatus, the thermostat being thermally coupled to a regulation resistor connected in series with a resistor, the resistance of which varies as a function of temperature.The latter resistance is thermally coupled to a differential correction first heating resistance and to a shift correction second heating resistance, these two resistors having different time constants and being energized, respectively, when the heating apparatus is turned on by the thermostat and when it is turned off.
