ABSTRACT:
A low wattage electrical resistance heating element is supported within a tubular housing, and an elongated flexible support band is adjustably connected to the housing and extends over a wall-mounted thermostat for suspending the housing in vertically adjustable relation directly below the thermostat. An electrical power cord extends from the heating element through the housing to an electrical power supply, and energizing of the heating element produces a convection current of heated air upwardly through the housing. The heated air mixes with ambient air and flows into the thermostat to provide an air temperature higher than ambient air temperature so that the heating system is controlled in a manner to maintain an ambient air temperature lower than the setting of the thermostat.
