If you build a small structure over the OWF, you can cut down the OWF’s exposure to the elements, thus allowing it to operate more efficiently. Humans have been burning wood as a primary source of heat for many centuries, and its use has evolved greatly over time. Since March 31, 2008, outdoor wood boilers sold in Vermont can emit no more than 0.44 pounds of particulate matter per million Btus of heat input. Independent Power is proud to be a dealer for Central Boiler outdoor furnaces serving the state of Maine. The second stream passes over the top of the combustion chamber and gathers the volatile gases being given off by the burning logs.

Although the heat is on for manufacturers to produce cleaner, more efficient units, it seems that the resulting innovation will ultimately warm customers and the general public to the prospect of outdoor wood heat, and spur advancement throughout the entire sector.

When manufacturers recently began to ramp up production of these devices, many of them used the same old inefficient box technology of the banned indoor woodstoves, which is simpler and less expensive to make – and just as smoky as the banned woodstoves. The outdoor wood burner boiler heats water, which is transferred to a heat exchanger inside your home.

You do not want too big a firebox even though most people assume that the more wood it will hold the less they will have to fill it. Consider that most of your heat will come from radiant transfer. The choice of quality insulated piping is very important to limit the tremendous amount of heat loss that can happen in frozen ground between the outdoor boiler and the building during winter months, therefore greatly reducing the system efficiency.
