I'm trying to heat a drafty old farm house in Michigan. about 2200 sq ft total. we have an Englander multi-fuel stove we bought 4 years ago that does okay, as long as the temp stays above 25 degrees f. It was supposed to heat 2200 sq ft, it might in better conditions, we don't even heat our upper level. We tried cherry pits, corn, and learned pellets are the best bang for the buck, and the cleanest, so that's what we're sticking with. I've been looking at other stoves because ours is starting to give us problems every now and again. The harmen p68 is what im stuck on. Kind of pricey, but it looks like it'll heat more area, burn any pellet, and what I can find is very reliable. I know of one that is 7 years old without a problem. I'm looking for some opinions good and bad. thanks
