Any bench style designs that dont use a barrel?

Im looking for an insurable RMH design that is bench style but without the barrel as insurance says they wont cover it for that reason. Has anyone designed one using something besides a barrel over the core? We're in the process of building an offgrid, permaculture housing community up here in Canada and wanted to use RMH's except for this hiccup.

I am just spitting out ideas here, but could you modify a wood burning stove to serve the purpose of the barrel?  Would your insurance company insure a wood burning stove?

We've thought about that but NS is picky when it comes to modifying anything even though something like 60-75% of us heat with wood up here. To satisfy funders/insurance we need some sort of engineered design or manufacturer. We dont got the $$$ to fight for a new untested or approved design. Our community is being supported by our local municpal gov with great enthusiasm so we got that going for us and they are open to new ideas...with caveats.

I am, at long last, getting ready to start a build of Matt Walker's Tiny House Cook Stove and Heater. It has a rocket core, a stove for cooking, and a bench. Can also be modified to add oven or water heating.

Ooooooooh Ty Burra this is exactly the idea we're looking for. Ill send this off to the team to run it by the managers. :)

I'm pretty certain any kind of rocket stove core can use a masonry bell in place of the barrel.

None of the batch designs require a barrel, so you have plenty of choice.

A J-tube does not require a barrel either, just an enclosure tall enough to contain the riser. Any RMH can be built with any shape of bell as long as part of it is tall enough to contain the core. If brick satisfies the insurance company you are good to go. Note that the International Building Code applicable to masonry heaters specifies that there be a double wall enclosure, such as two layers of brick, so that a leak in the inner wall does not transmit through the outer wall. There are other terms some of which are slightly ambiguous like overall thickness of walls.
