It consists of (1) a finned, steel burner tube, a combustion air blower, a control panel, and a constant level fuel supply system or (2) a device having a heating element which when connected to an electrical source, directly imparts heat. It may be provided with a flanged outer casing to facilitate mounting in planned or existing duct work. Circulation of the heated air is achieved by use of a blower or fan not integral with the heating unit.
