Hi, I’m considering a used 1125 for my 1,000 square foot home located on a windy mountaintop in NEPA, which is well insulated. I do like a bit of fresh air inside in winter but can’t crack a window with my electric baseboard heating, which is just getting more and more expensive. Any thoughts? It seems from what I’ve read here, this stove can burn low and long if it’s set correctly, which is what I’m looking for. It will vent straight up through the roof. My concern if I set up for an 8” vent and the stove doesn’t work out, will it be a problem to switch it out with a 6”? Also is it too much for my small space?
