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.

Vented zone heating systems may be installed as the primary heating system.

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.
