Abstract
A heater element for an electrical appliance (especially one having a blower, such as a fan heater, hair drier or the like) consists of a resistance heating wire looped in linear formation (e.g. zig-zag) and held transversely of the air flow direction by at least one support plate disposed parallel to said direction. The element has a voltage tapping point at the tip of one of the loops which projects beyond the other loops and has its tip fixed to an insulating panel parallel to said support plate. Said tip may be riveted or secured by an eye in a recess in said insulating plate.
