Abstract:

A radiant panel type heating apparatus includes a heating element comprising a sheet of electrically conductive paper which generates heat as a result of resistance to current flow therethrough. The heating element includes spaced apart primary conductor elements comprising thin copper strips which are sewn to the conductive paper to provide uniform distribution of current flow through the paper from one conductor element to the other. The heating element is sandwiched between a main insulative panel member on one side and a heat conductive panel member one the other side to form a heat radiating surface. The heating element is secured in assembly with the panel members by strips of non-conductive and heat resistant double sided adhesive tape. The panel type heating apparatus may be provided in various geometric shapes and includes a thermal switch and fuse assembly to limit the maximum surface temperature of the heating element.
