Heating ideas for a shop with living space above it
Hey guys. Hoping to get some opinions here. I’m building a small detached shop with about 600sf of living space above it and I’m trying to decide on heating methods. I guess, really I’m trying to decide on a heating method for when we are out of town so things don’t freeze up. Our main heat source is a catalytic wood stove but I’m torn on location. The downstairs is mostly shop but a wall seperates about 150sf of living space, bathroom, laundry room and stairs. We’re in Montana so every now and then we get extended periods below zero. I can’t say its a super insulated envelope but it is tighter than most. Slab is poured on R10 XPS. Walls are flash and batt with 2″ closed cell and 4″ batts so around R30. Roof is single pitch unvented with 6″ of exterior foam under rubber membrane. Standard 12″ batts in the ceiling, no recessed lights, sealed electric boxes, etc. We do have a fair amount of glass, lots south facing but the windows/doors are nothing special, somewhere around U.28. Pella Fiberglass dual pane.
Basic drawing attached.
So the questions:
– Where would you place the wood stove? Ideally I would just put it in the shop and vent it upstairs and into lower living space but I don’t want to bring shop air into the house.
– If the stove was upstairs, how would you heat the bath/laundry rooms downstairs?
– How would you heat the shop?
