ABSTRACT:
An electric space heater unit includes a casing having front, rear and end walls providing an enclosure. An imperforate copper heat collector plate is disposed within the enclosure intermediate the top and bottom of the casing and extends the length and width of the interior casing space so as to divide the casing to a lower closed heating chamber and an upper heat distribution chamber. A plurality of conventional frosted 75 or 100 watt incandescent lamps are provided in the lower chamber in direct heat conductive contact with the undersurface of the plate. A heat radiation member in the form of a sinuous metal strip or a plurality of metal fins on a common metal support is disposed in the upper chamber in direct conductive contact with the upper surface of the plate. The top of the casing has an opening for passage of heat from the upper chamber into the space to be heated. The rear wall is contoured to reflect heat outwardly through the opening. The number of lamps energized can be varied to adjust the level of heat output.
