Abstract
An electric heating device including a fan for moving a volume of air at a rate substantially corresponding to a speed of rotation of the fan, and a fan motor for rotating the fan over a range of speeds. The device also has a heat generator with one or more PTC elements for generating heat, and for transferring the heat to the moving volume of air. In addition, the device has a control subassembly adapted for proportionate control of the fan motor based on a variable required heat output so that the rate of movement of the moving volume of air varies in proportion to changes in the required heat output.
