Back in August, I asked this forum for recommendations for a sealed fireplace insert to install in my new North Texas home. Got wonderful response and lots of information for me to research. Recap: house is single story, ranch style, about 3000 sq. ft. The fireplace is located in the the great-room and that room is approximately 20' X 21', centrally located in the home, and open to an adjoining Kitchen/Breakfast area that is 24' X 24'. I think that I have my choices down to the FPX Xtroidnair 44 or the Quadra Fire 7100. I'm told that the Xtroidnair is a "cat" firebox and the Quadra Fire is not. Will either one of these choices be better to operate in my home, without over-heating the great-room area ? One dealer says the "cat" will allow more flexibility in the size and temperature of my fire, and the Quad will be too hot. Quad dealer doesn't seem to think his unit will be too hot for the area. Here in the South, probably neither one has much hands-on experience, like some of you guys who have many years' experience. I think I would prefer the non-cat, but I'm really not sure. Any suggestions from people who know about heating with fire ? Oh yeah, wood will just be supplemental heat to back up a Trane XL19 central unit. Thanks.
