I just joined today and need advice which Hearthstone to choose. I had a dealer come out yesterday and he said the Heritage is the largest that would fit in my fireplace. My fireplace is 32X46 and the Equinox would work, except for the 6.5 inch rectangle flue. I talked with someone else and he said that you could get an 8" oval pipe. Is this true? I'm just afraid that the Heritage will not put out enough heat for my 1948 drafty house. I will be heating 1800 sq. ft. downstairs and hopefully another 1200 upstairs, although I like the upstairs cooler, around 65 degrees. The fireplace is located in the center-front of the great room. The great room is 34X25, with the kitchen, dining room 16X33 on one side, and a bedroom 17X23 on the other side. My kitchen is always cold, being on the north side of the house. I plan to use a fan to pull the air into the kitchen. I have a stairway off the great room and one in the kitchen, so the heat can rise upstairs. I also have a glass sunroom on the wall opposite the fireplace that gets cold. The only plus with the glass is when the sun shines and warms the room during the day. I'm really scared to get the Heritage and find out it's not enough heat. It's a lot of money not to work. I really need advice as I've never owned a wood stove and my fireplace uses too much wood and is too inefficient to use all the time. Also, I really like the looks of the Hearthstone and the even heat versus steel or cast iron. HELP?!
