Hello guys, I've got question and need some advice. I currently have a quadra fire 4100i insert. I have only one complaint about the glass getting dirty but thats not what I am interested in now. I have a 1700 sq bi-level house. So the layout is far from ideal when it comes to circulating the significant amount of heat produced by the insert. It has a variable speed blower w/ thermostat. It heats the room it is in on the first floor extremely well but the heat takes a long time to make up to the second floor. The stairway is through a door and then opens to the top floor. I was thinking about putting a floor vent to allow some more heat to rise to the second floor but I wanted to get some input about other options before I started cutting holes in the floor. How do you circulate the heat more efficiently? Any help is greatly appreciated. Thanks a lot.
