ABSTRACT:
A heating device is disclosed having a disc-shaped heating element consisting of PTC thermistor material typically operated by a network voltage of 220 volts. The PTC thermistor material has a cut-off control property at a desired cut-off temperature so as to minimize further heat rises of the heating element above the cut-off temperature. In this fashion, the possibility of fire damage is reduced. The heating element has a specific heat output of greater than 50 watts per cm.sup.2 and the PTC thermistor material is selected to have a Curie temperature which is at least 50.degree. K. higher than the cut-off temperature. A heating body is provided to affect a substantially even dissipation of heat from two sides of the heating element.
