I need to heat this formal room and the rest of the open floor plan which is a total of 2500sf (includes the 22' ceilings). I am thinking of getting the Buck stove model 81(heats up to 2700sf) or the model 94NC (heats up to 3200sf). I am concerned about the real high ceilings and all the windows that I have surrounding this area. Will I be able to heat this area adequately? I have two return ducts on the ceiling to the left and to right of the fireplace which the dealer tells me I can use my furnace fan to circulate air to the rest of the house. Any advise, or recommendations will be greatly appreciated. Thank you
