ABSTRACT:
An electrical space heating element having a ceramic body which is provided on the side facing away from the space to be heated with an electrically resistive coating. The space heating element provides a high thermal yield while consuming little electrical power and may be used as an element of design for the periphery of a room. The space heating element may be installed in such a way so that no channels are formed which might force air currents to circulate in the room to be heated. The electrically resistive coating is a layer of a carrier impregnated with nonmetallic particles which have a large specific area, are electrically conductive, and do not substantially vary the electrical conductivity at higher temperatures. The carrier in which the nonmetallic particles are embedded has no greater than poor electrical conductivity. The electrically resistive coating is applied in such a way that it has uniform electrical and thermal conductivity.
