My outdoor wood furnace is using too much wood so I looking to install a wood stove inside. I like the look of a in wall wood stove and its smaller footprint in room. But I can't afford /justify paying $3k + for one. I had the idea of removing a section of wall between living room and utility room and building a stone wall and put a wood stove in it with wings/flanges welded to sides and top to make a clean looking install. Or find a big enough efficient insert at a decent price. The wall will be 6' wide 9' high. I want to go with a stacked stone look. I still deciding on using real rock( I have plenty) but will be a huge project or go with a veneer with cement board and steel studs which will cost lots. Since it will be a non combustible wall what type of clearances do you think I can get away with? I was thinking 6" . How far up wall do you think the heat will transfer at unsafe temp.
