Add-On Wood Furnaces

Our JACK Line add-on or stand alone wood and coal furnaces are the only UL Listed (approved) central fired solid fuel furnaces on the Market today. When you move into burning wood for heat, the UL Mark is what your insurance company will be looking for. 

30-Year Limited Warranty - We have the best warranty in our industry!

GASIFICATION - Our JACK's are designed so that air is brought in on top of the fire so the most BTU's available in the solid fuel are used to heat your home efficiently - a JACK furnace will use 75% LESS wood than an outdoor boiler or wood stove.
