I am in se Wisconsin and I am heating 1750sqf. I bought this stove because my 7100 was hooked up to my heating ducts and there are not that many stoves out there that have the feature. I got interested in the 8500 because of heat but I also got it for a great price of $1953 and $140 to ship it from Rural King out of Illinois. I was so tired of cleaning the 7100 tubes all the time from pellets, and I wanted a stove that would also burn corn, we are all setup for corn (burned it for 7 years). So far so good and my wife loves the temp of the house. So it's a win win.
