Its good to know that their not too hard to get going, and I think there's a decent chance that it may be able to heat our entire house, at least I'm hoping it will. I have a three level chalet style home(big drafty barn) thats probably 2500-3000 sq feet, so we'll see how it does. The Hitzer seems very well constructed, and they changed the doors, their now cast iron instead of just steel plate, their really heavy. I went with the Hitzer because of all the folks here talking about them, I had tried to get a Harmon 250 but that wasn't an easy unit to find. I was so thrilled to find a dealer with Hitzers in stock only 50 miles away, and the fact that he still has more is mind boggling, I thought everywhere was cleaned out at this point. May call him and ask how he's doing, mentioned it because I had such a hard time finding mine, just wanted to help others out.
