Abstract: A resistance heater element for an electric room heater includes a resistive heating conductor (1) supported by an insulating support (2) mounted on the support flange (9) of an electric fan (4) in the heater which passes a stream of room air across the conductor (1). The insulating support (2) is cylindrical, with its axis parallel to the direction of the air stream, and includes at least one pair of nested mica bands (5, 5') bound together by fillets (6) connected to the support flange (9). The heating conductor (1) comprises at least one wire of resistive material bent in a zig-zag manner to form a plurality of radial loops each having portions extending inwardly and outwardly of the cylindrical bands (5, 5'). The central portion (11) of each loop is bent over and retained between the pair mica bands (5, 5') with the inner portion of each loop emerging radially from the inner band (5) through apertures (13) provided therein.
