Thank you for the inputs guys.  Max you have given me a couple more ideas to explore.
I'm thinking of maybe trying to use some steel barrels and adding brick and limestone mass around the outside.

Hi everyone !  I'm experimenting with  a rocket heater. I'm using a 6 inch j tube. I'm looking at building a bell for the heat storage.  My question  is can I use  8x8x16 concrete block and fill the open cavities with a cob mix to remove the air pockets?   Most of the ones I've seen are built with red brick.  I have a cheap supply of block available.  Thanks for your advicell and time

Hi Dave thanks for the welcome. I'm located in northern Illinois and my thoughts are two fold. 1) heat rises so will warm the upstairs floor and 2) having a heat source to dry my winter work clothes

This may have been covered before. I'm new to this style of heating. My question is which is better  thermal mass bench with ducting or a stratification bench.  Looking to build in my basement to keep it warm
