I’ve been burning a Hearthstone Heritage since 2012 and am now thinking of switching to a cat stove for longer burns and lower heat output. I really like the soft heat of the soapstone so I’ve been leaning toward a hearthstone green mountain. On the other hand, the Ashford has a solid track record. I have about 23 feet of double-wall and insulated flue running straight up through the house. Should I be concerned about excessive draft with the Ashford? Or the GM? I do have a key damper but not sure if it’ll be enough to reduce draft for the Ashford.
