ABSTRACT:
A room air heater which includes a vertically disposed tubular housing or casing mounted on a mobile supporting structure for ease of movement to a desired location and including a heat exchange coiled tube communicating with a tank having an electric resistance heating element disposed therein. The tank and heating coil are filled with a heat exchange medium in the form of compressed air which circulates through the coil and tank due to the heat imparted to the air by the heating element. A circulating fan is provided in the upper end of the housing for forcing room air downwardly therein in heat exchange relation to the coil with the housing having openings at the bottom thereof for discharge of heated air. Manually adjustable thermostatic controls and a pressure gauge are provided for enabling safe operation of the heater.
