How an Outdoor Furnace Works

How It Works

A water jacket surrounds the furnace firebox and heat exchanger, and heated water is circulated to the home or building through insulated underground pipes, an efficient way to move heat over distances. WoodMaster outdoor furnaces are designed to work with any existing heating system. Water-to-air or water-to-water heat exchangers or direct circulation conveys the heat into the structure's forced-air furnace, boiler or radiant floor heating system. This allows you normal thermostatic control.
