What is an
Outdoor Wood Furnace?

An outdoor wood furnace is as the name implies - a furnace that sits outdoors. The furnace, looking much like a small utility building, is a wood-fired, water-jacketed stove. The water in the jacket is simply heated and pumped underground through insulated pipes to the building that needs to be heated. At each building, the heat from the water is extracted.

This process is not expensive and adapts easily to all heating systems. The outdoor furnace concept is very simple, effective, safe and cost-efficient. As a bonus, it also takes care of all your domestic hot water needs; the element in your hot water heater need never kick in. (see furnace sizes below)
 

Benefits of an Outdoor Furnace

Safety
Our furnace is made to be situated in the yard, away from the house. The usual distance is 50 to 150 feet but it can be twice this distance and still do the job. Outdoor furnaces remove the dangers of wood stove fires in the house. Any fire department that compares the safety of indoor units versus outdoor ones will have to admit that outdoor furnaces are the winners.

Convenience
The furnace is located out in the yard and can be situated beside the wood pile. This eliminates the mess of sawdust, smoke, ashes, bugs and dirt in the house. Our injection air furnace burns any type and quality of wood, wet or dry, un-split and in lengths of up to 72". The burn time average can reach 48 hours or more per fill. One furnace can heat multiple buildings; there is no need to purchase a heat source for each. (see furnace sizes below)

Cost Savings
Residential and commercial buildings, shops, garages, motels, factories, restaurants can all be heated easily with our furnaces. There is no more need to use gas or electricity to heat domestic water, hot tubs, swimming pools, clothes dryers - our furnaces will do it better and at a fraction of the cost. Additionally, the safety of an outdoor furnace (discussed above) can sometimes result in lower insurance rates.
