I am looking for reccommendations for an efficient wood-burning insert. We are building a new house and have a chance right now to change the chimney if necessary. Without doing too much research I spec'd a Fireplace Extrordinaire 44 Elite. I like the look of it, and it's big, and you can see a lot of fire through the windows...and it has a good efficiency rating, I think...but I did see on some of the ratings that there were some problems with cold air infiltration...one person said they wondered if you couldn't draw air from inside the house, so as to reduce the problem with cold air drafting in from the chimney. Anyway, I'd appreciate any informed reccommendations for an insert that is big and nice-looking with good efficiency and big glass doors... while we still have time to change the chimney set up if necessary. And any reccommendations on modifying the 44 Elite's reccommended setup to avoid known problems. Thanks!
