This top-vent counterflow wall furnace by Williams Furnace Company is a highly efficient indoor heating unit that, operating at 35,000 BTU, works to safely distribute heat throughout any indoor space at minimal cost. Ideal for homes, apartments, offices, and schools, this unit is conveniently compact - just 10 1/4 inches deep and requiring less than one square foot of floor space - for ample heat wherever you need it, regardless of the size of the room.
Counterflow furnaces operate by utilizing an internal blower system that, coupled with an efficient heavy-duty motor, receives air at the ceiling level through the top of the unit that is then warmed (quietly) and redistributed through the bottom towards the floor. Because warm air naturally rises, the heat delivered at the floor level becomes evenly disbursed throughout the entire room, for consistently comfortable interior temperatures. All wiring and controls are easily accessible from the front of the unit, including a wall-mounted thermostat that works to prevent excessive temperature swings, for added control as well as added energy/money savings.
