If you have a massonry wall in the house, you could heat it with one side of the bell. If made square like old home heating fuel tanks, or agricultural fuel tanks.
Here you can see the double barrel bell on Peter van den Berg horizontal batch rocket.
May be you could make something like this. Two stacked barrels on your rocket. No worries about the barrel gap then. Plus two stacked barrels, like this, aside the rocket, aranged as a bell. Vertical bell, with intake and exhaust at the bottom, and which would store and extract heat from the flue gasses. Then, you could use a little mass around the second set of barrels, to keep warmth a smidge more.
Myself, i'm on the track of using square tanks, and covering theses with bricks, dry stacked. Whenever i can find tanks which i like.
In other words: why run pipe through the bell rather than running pipe TO the bell, then FROM the bell at the other end?

a row of 6" pipe right off the riser up and down with a bunch of 180 degree joints (about 20' worth)
