Hello, I am in the process of shopping for a new stove insert to replace my Vermont Castings small winterwarm 2080. We have narrowed down our choices at the moment to the BK Ashford 25 and the new Hearthstone Clydesdale. I am trying to understand a bit more if the hybrid function of the Clydesdale will allow for more adjustability? We burn fall through spring so leaning towards a cat model. Also, both fire boxes seem to be about the same size by Heathstone advertises the stove, if all the stars align, will put out close 60000 BTU vs 30k or so for the BK. I am not quite sure how one can produce almost twice the output with similar size fire boxes? For reference, on cold days (~20-30 degrees) the Vermont Casting will heat the room it is in to about 67 degrees currently. The home is in Rhode Island, oil heat, two stories and approx 1900 sq ft, built in 1920 but does have updated insulation I would call adequate. The fireplace is in the middle of the home with a staircase approx 4 ft to the right, and I am not sure of the chimney height at the moment. I appreciate any insights you can share.
