Ah - I missed the 6" part of your question. A 6" J-tube may work well enough fitting in a 90cm overall height.
Then I only shortly the barrel and the chimney in order that the distance between them above is not minor than 2 " and it will work without modifying another distance?
I like thebatch box designs very much but is a new type for me to study, and I do not feel so sure of managing to construct it well, I will Investigate more before the final model define.
The space is a new costruction.
The concrete base is not done jet.
I have a rocket stolve where I live now and I find very usefull the "mouth" on the front to clean it easily.
I would like to place a glass somewhere to see the fire burning.
The cooking ability is important.
It will work as a Breakfast Bar.
It is located in San Luis, Argentina. There are many thermal amplitude. In winter during the day we have between 12º and 15º, while at night we have temperatures up to -7°.
I made a plane with the idea I have. I dont know how to modify it to reach a 90cm tall RMH and not a taller one.
I will instal also Trombe walls for the living room and the rooms
If you need some other data please ask.
I`ve ask the owner and here is his answer:
it works very well, but I would change something: as you can see, the barrel is completely hidden in the stove, as opposed to these rocket stoves where part of the barrel is exposed.
The consequence is that my rocket stove has a lot of inertness and thermal mass (stays hot very long after the fire has been extinguished), but there’s not much direct radiant heating. And it would be nice to have a bit more of that.
I want to know your opinion on this RMH model by francis jonckheere / ony one . I want to build a RMH no more than 90 cm and found this model that I really liked. I do not really understand the operation of the two channels. I ask your opinions and recommendations.I`ve attached the plans.
