Hi folks! What I'm trying to figure out is what many of you have likely before, how to distribute the heat of my stove from one side of my house to another using duct through the attic. Going to try to keep it simple: What I have is a 1-story original cabin home with a 2-story addition built on(3b/2ba/1600sf). The addition steps down about 20" from the original cabin (so getting heat to travel down to it can be a challenge as one single 34"x78" door way connects them) The original cabin houses the stove and we keep it around 76 in that area. The bedrooms in the addition side are coldest about 12F lower than the original side. What I was thinking about doing was adding a duct with a blower to blow from my stove area to the stairway in the 2-story addition to help distribute to bedrooms. I am masonry contractor and can do about anything I just don't have the know how for this project so here is a few easy questions bear with me: 1) What size ducting should be used, the vertical run is 3' and about 30' horizontal run. It is a straight shot. I would assume I should avoid flexible ducting? 2) What size blower fan? Should these be wired on their own circuit or could I add it to another with little on it? 3) The room has a flat ceiling (attic above) but does have one cave style skylight very close to the stove would it be better to draw air from the skylight inner wall vs. flat ceiling plane? Thank you for your help in advance. I am sure I may have a few more questions but I'm really excited to get some input and get started on my project !
