So we're in the planning stage to remodel our two story 2400 sq ft colonial, making the first floor an open concept (the house is currently pretty sectioned off- 1970s era stick built). We have a new Jotul C550 insert in the south wall fireplace and absolutely love it. The north wall (50 ft away)- we're thinking of installing either a large window, a ZC or a freestanding stove. Would a second wood burning appliance be overkill? We added insulation and replaced all the windows via a state energy conservation program, which helped make the house much less drafty. Early spring of 2020, when the overnight outdoor temps got into the low 40s, the fp side of the house was easily in the high 70s. We're in central MA, so it can definitely get cold in the winter. I appreciate your thoughts and thanks!
