I’m wondering if it’d work okay to scale this system down to a 4” one. I’m living in the foothills of the Himalayans, and the local stoves all have 4” flues. I would use it (at least for this season) solely for heat and some cooking. I won’t do the mass heater part or even the extra part for warming water. I don’t have a lot of room, and it’ll be freestanding in the middle of the room (I’ll move it at the end of the season). Basically, I’m thinking about building your riser-less core and adding a top to it (granite, concrete, or a big slab of rock). I can get the ceramic fiber panels, and I’ll put a metal casing around the sides and bottom. Do you see any red flags to this? I greatly appreciate your help, and I greatly appreciate you sharing this new system you’ve developed!
