Gravity Wall Furnaces


Green Heating with Gas

The Gravity Wall Furnace offers total comfort for a fraction of the cost of electric heat. The furnace’s common size retrofits easily. Designed for installation in a standard 2 x 4 stud wall cavity. Optional Out-of-Wall Kit (GWTW2W) allows surface mounting and encloses the sides.

The 50,000 Btu GWT50W installs in the wall between adjoining rooms and heats both.

For the smaller GWT25W and GWT35W, an optional Rear Register Kit (GWTR1W) directs heat to an adjoining room.
