What's in the bottom of yours Fstyles? Steel? Or stainless? I didn't know that your stove was so young...
So that's too small a rocket for 100m².

The mass would make a difference in the long run for sure but not in instant heat.
Its been a long time since I measured the exit temps but they werent that high, maybe 50 C after I put the bell on it .

If it is drawing air in that well then that air must be coming from somewhere. It could be that it is pulling an amount of cold air into the house that is killing the efficiency of the stove. In an uninsulated space it probably only effectively warms up the area immediately around it. You could set up one of those reflective emergency blankets and sleep between that and the stove to stay warm but I doubt it could warm the house as-is.
Adding some sort of restriction to the exhaust could help slow down the burn. I remember seeing a video with the exhaust routed into a second barrel that was filled with bricks as a thermal mass, but I can't seem to find it at the moment. Rocks or other mass could also be used. It wouldn't heat the entire place but it could be enough to hold you through till it is warmer when you can build a better stove/heater.

There are other threads describing the overall system, but not in such concentrated form.
So you made a portal in time and started grabbing people. This tiny ad thinks that's rude:
