I have a two story 3200 sq. ft. Center hall colonial with a bonus room over the garage and would like to install a second stove in this room, something small. I have an insert downstairs and it does a good job of heating my home, only needing to fire up the boiler a couple of times a year. The bonus room only gets up to about 62 degrees and I would like to spend more time in there. My concern is will it effect the draft and will it get too hot.
