I will be building my rockety type stove outside, on wheels to avoid issues with the man, and my insurance company.
I want to bring the heat inside, and distribute it throughout my modest two story.
I have been leaning towards using water as a transfer and storage medium, and my existing blower to distribute the heat around the house.
To avoid boom-squish, I would use an open system and t&p valves.
At what point in the system should a coil or water jacket be introduced?
The barrel is the first place heat is extracted in a "conventional" mass heater rocket, but apparently the combustion is still taking place,so taking too much heat energy away at this point is nono.
And yet the principles of the device seem to require some heat loss at this point, otherwise , why not insulate the barrel as well?
I am wondering, is the draw created by the heat riser strong enough to push the exhaust into a container of water, and if so, would the exhaust efficentlt transfer the heat energy it contains to the water, while being filtered in the process?
Think of a huge water bong without any giant dude to suck on the end...
I did considering running the exhaust itself into a thermal mass inside the house, but the man , the insurance company and moma all object to pushing any form of exhaust into our house..
An air(exhaust) to air(house) system would let me capture the heat, but less efficiently, and with more bulk.
The only way I see going that way is as part of a passive solar/greenhouse setup , where the RMH is in the greenhouse anyway...
I did view the waterjacketed RH video, a while ago. Can't remember where their jacket was placed, but they managed to get away with siphoning that heat off, and still getting a clean burn.
Guess I will have to go back and check, but not right now...
William Bronson : Congratulations for thinking outside the box, the safe operation of this system requires a 100% off-grid solution - what do you do if you lose power
to operate the bells and whistles ! Building a self syphoning system is not hard, but any stoppage gets you back to an over-heated pert of the system 'Flashing to
Steam !' - - Bang Squish ! Watch this space, when the last wrinkle and bug is worked out of the system you will see it posted here
For purposes of satisfying your insurance and the Housing Code man an outdoor Rocket Mass Heater R.M.H., is usually considered a masonry heater due to is weight
class. An outdoor kitchen with a masonry heater w/ grill should not raise any eye brows, with proper wind breaks you could end up with a Micro climate that would
extend your use of the outdoors !
A D.I.Y. Builder friend has a 'Cob Oven' complete with Roof to protect the Cob, total weight of the Cob and Trailer is around 3 Tons, he got exactly what he wanted,
I just mentioned it, because you were considering putting your R.M.H. on wheels !
This is just one mans suggestion, go to You Tube and enter Web4deb in its 'search engine' this should take you to the web4deb channel, you want to scroll down and
click on his Rocket Mass Heater playlist ! This should give you ideas Good luck ! Think like Fire ! Flow like Gas !

Thank you brother for your comments! Iwill indeed watch those videos, next best thing to being there.
The chance of flash over has me thinking a water jacket would be better than a coil.
A loose fitting cover, or none at all (!?) and a good sized resoivar, to gravity feed the jacket, it being topped off with city water in turn.
I am concerned that thermo-siphoning would only work if my heat source was located lower than my storage.That could be very inconvenient.
More thought and study is needed, but first to finish the rocket itself...
