I have been burning with a Jotul 550 insert for 3.5 seasons now and I am wondering how much more heat (if any) I could get with say a Woodstock Progress Hybrid or any free standing stove? I have an open floor plan great room with cathedral ceiling open to the hallway and bedrooms upstairs. 2,500 sq. ft. The ceiling fan keeps the heat downstairs pretty well and circulates it to the kitchen at the other end of the house. The chimney is on the outside of the house and is 28+/- ft high and the liner is not insulated. I do have a top and bottom plate. Thanks for your thoughts/help. I also like the idea of no fan noise.
