Hook up wood stove to furnace

opinion

Connecting your wood stove fan so that it services all of your central heating ducts can be done efficiently only if the fan is connected at the furnace plenum.

The plenum, which is essentially the heat distribution box, is located on top of the furnace. Therefore, to make this task practical, the wood stove must be located adjacent to the furnace so that the fan can supply the plenum with heated air. In all other areas where the wood stove is located, it would be an impracticable endeavor to hook into the central heating ducts and expect even a minimum of heat at the registers.
