I bought a Regency wood stove insert and it is a hazard. First, it does not heat so much as a room, much less the square footage advertised. I estimate that I could go through a cord of oak in 3 weeks and not get any appreciable heat output. The fan does not work until the stove heats up and then it is loud. Until the stove heats up the fan box allows a reverse air flow pushing smoke into the room. The reason that smoke come out of the unit and goes into the room is that there is no draw up the chimney. Enough smoke will come out to set off your smoke detectors. It is almost impossible to start a fire without smoke coming into the room; either through the fan box, leaking seals or opening the door to try to restart the fire to eliminate the smoke production. The installer and seller are no help as there is no agreement that they have warranty duties. Save your money and try something else. I have two space heaters that operate at less cost than wood for the stove without the smoke problem.
