I'm looking to buy a wood stove insert, looking at the Jotul c450 or the Hampton hi300. The house is a dutch colonial about 1300sqft. The fire box can fit a Jotul 550, but due to price and i don't think I need one that big. The Hampton is $300 cheaper due to a promotion going on for a free blower. Also in the Jotul manual my hearth needs to be extended to 20", its at 18" right now and adding any more to it would make it stick out in the room more, the room the fireplace is in is narrow but long. I've been reading other reviews and found some on the Hampton saying that they can't get good heat out of it. Any help would be great
