Classic Wood Furnaces

The Classic outdoor wood furnace is located outside, typically 30 to 200 feet (but as far as 500 feet) away from your home or business, and works with an existing heating system. A water jacket surrounds the furnace firebox and heat exchanger and heated water is circulated to the home or building through insulated underground pipes. 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 for normal thermostatic control for safe, even, clean and comfortable heat. The ability to heat multiple buildings and domestic hot water can eliminate your heating bills. Outside burning removes the threat of devastating chimney fires, dangerous carbon monoxide or oxygen depletion which affects your indoor air quality. It also eliminates the smoke, ashes, odors and soot buildup on walls and ceilings inside your home that indoor burning creates.

All classic wood furnace models are also available as a Dual Fuel Ready model. This allows the furnace to be fitted to work with options other than wood including a propane burner, fuel oil, or natural gas. This Dual Fuel Ready feature comes standard on the CL7260 and Pellet Burner, but it is also available in all other classic models.
