Outdoor Wood Boilers or Wood Furnaces Compared to Indoor Gasification Boilers

indoor and outdoor wood boiler examples

Tarm Biomass sells indoor wood boilers.  Indoor boilers can be located in detached buildings outside of the primary heated space, but they are not weatherized like outdoor boilers or outdoor wood furnaces.  Indoor boilers generally provide better heating performance, as heat losses from the appliance and pipes go to the home rather than outdoors.  Customers who have switched from using outdoor boilers to indoor gasification boilers have reported reducing wood consumption by half or more. For a more detailed comparison, visit our resource page.  Due to problems with smoke from outdoor boilers and outdoor wood furnaces, they are banned in many areas where indoor gasification boilers remain legal.  New York and Massachusetts pay cash bounties when outdoor boilers are replaced by indoor gasification boilers.  For more information about these programs, click here.
