Abstract
A heating element for an electrical appliance having a blower (e.g. a fan heater or a hair drier) comprises a wire looped in linear formation (e.g. zig-zag or sinuous) the loops being held in position by support plates so that there are at least two loop rows transverse to the air flow direction and disposed in succession in that direction and so that the loops in one of those rows are placed opposite to gaps in the other. In an element having four loop rows with a center taping for two-stage power control the electrical connections are disposed on only one support plate with the center tapping connection at the same side of the plate as the means supply connections; also, the loops in a first pair of rows are aligned with one another and are offset from the loops in the second pair which are also aligned with one another.
