Vented zone heating systems use room air to support combustion and exhaust their flue products to the outdoors via a single pipe. Mounts anywhere you have access to an existing flue or where you can install a vent run through the roof. A vented zone heating system makes an excellent replacement for an inefficient oil or wood stove.

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.

For the smaller GWT25W, an optional Rear Register Kit (GWTR1W) directs heat to an adjoining room. Our economical Gravity Vented Furnaces utilize state-of-the-art technology for better fuel efficiency. Recesses into a wall or surface mounts with the optional kit.
