The Classic outdoor wood furnace is installed outside, typically 30 to 200 feet (but as far as 500 feet) away from your home or business and works with any existing heating system.

A water jacket surrounds the furnace firebox and heated water is circulated to the home or building through insulated underground tubes. Water-to-air or water-to-water heat exchangers are installed into the structure’s forced-air furnace, boiler or radiant floor heating system. This allows for normal thermostatic control of temperature for safe, even and comfortable heat.

The ability to heat multiple buildings and domestic water can eliminate your heating bills. Outside burning removes the threat of devastating chimney fires and the dangerous carbon monoxide buildup 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.
