When the G-Class product line was first introduced by Polar Furnace it included many features never before seen in the outdoor wood furnace industry.

Polar Furnace presents the G-Class wood furnace in multiple sizes. The G-Class furnaces are downdraft type EPA qualified wood gasification units, which insures they will be legal for years in your community.

Polar Furnace released a series of videos showing some of the benefits of heating with a G-Class heater.
