Abstract
A radiant heating device and a method of forming such a device are disclosed wherein a metal heat radiating plate has a first surface for forming a front surface of the heating panel with the surface opposite that first surface having an electrically insulated sheet heating element affixed thereto. The plate and heating element are embedded in a flowable material to cover the heating element and the plate edges about substantially the entire periphery of the plate while leaving the plate front surface substantially material free and that flowable material solidified to form an electrically and thermally insulating frame for supporting the plate and the heating element. External lead wires and an on-off switch for controlling the supply of electrical energy to the heating element are connected to the heating element prior to the embedding process with the switch positioned so as to extend through the insulating frame after solidification to be positioned in a frame border portion on the front surface of the heating panel for easy actuation by a user. The flowable material preferably forms a flame retardant frame when solidified.
