I currently have a Clydesdale insert heating my 1500 sq ft. ranch with a fairly open floorplan and central fireplace location. I get good heat but have considered going to a freestanding stove. I like the idea of not running a blower 24/7 to heat the house. The Phoenix has the same btu output with maybe a tad lower efficiency, will I get the same heating ability from it as my Clydesdale? I'd like to find a Heritage but used they don't seem to pop up often. I've heard through the grapevine about a Phoenix but really don't want to swap out without any real benifit. This wouldn't be an even swap, I'd likely pay more for the Phoenix than what the Clydesdale would sell for. I also have a short chimney. I currently don't have issues with the Clydesdale drafting although my chimney is only 12' from the insert to cap, are other Hearthstones more draft reliant?
