How It works

An outdoor wood boiler also known as an outdoor wood furnace is a heating appliance that sits outside the home while providing heat to the home. The boiler is a wood fired combustion chamber that is surrounded by a water jacket. The water in the jacket is heated and pumped underground through insulated pipes to the home that is to be heated. Inside the home, the heat is put into the existing furnace via a heat exchanger and into the water heater via 2 methods, a water pre-heater and/or a side-arm attachment. Once the heat is used, the cool water is returned to the boiler to be heated again. This cycle occurs over and over as the heat demand increases or decreases.
