ABSTRACT:
A thermostat controlled window furnace for heating a room features a construction wherein the air required for its operation is comprised on the one hand of outside air used solely for combustion purposes, to service a heat transfer component, and on the other hand of air drawn from the room, to be heated in passage through the heat transfer unit and returned to the room to elevate its temperature. The arrangement provided for inflow of room air insures that it will exhibit the general temperature of the room. The furnace not only provides for an effective separation therein of outside air and room air which is utilized thereby but for a return to the room of heated air in a manner to inhibit a chance or premature intermingling thereof with that portion of the room air being drawn into the furnace the function of which, in part, is to signal the general temperature of the room to a furnace thermostat.
