Lots of variables with how much any given stove will heat. It would be nice if manufacturers could help out a little more as far as information about the rated output, but if you think about it, it's really not very simple. I guess you would need to know how many BTU's it takes to maintain a certain temperature in your house compared with outside temperatures. I know with my old house, the wind is another big variable. Our Hearthstone Heritage is rated for the square footage of our house, and it works fine when outside temps are at least 15 degrees F. When it gets down around zero and below it doesn't keep up. On weekends when your home, you can keep the air open and load up every couple hours, it isn't too bad, but that does you little good during the work week. Sure, we could've gotten a bigger stove, but then maybe we'd have too much heat a lot of times. I'm not sure how good it would work choking it down all the time. Average winter temps are ok, last winter sucked, especially with the LP prices last year.
