90 cm high rocket mass heater

Hi, I want to build a RMH 90 cm high from the floor to the highest point. Has anyone plans or ideas? thanks!

Yes, there are several possibilities, but we need to know more about the situation and your desires before we can give the most appropriate answers.

Is this for an existing space, or new construction? How big is the space, and how severe is the heating load? Is cooking ability important?

Thank you Glenn, I will describe the situation:

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 will be greatefull with your opinions.

May be check those threads.

I didn`t find still, how to built the rocket so that it don`t overpass the 90cm.

I will use the top of the barrel to cook. That`s what I mean when I wrote "cooking ability is important". I did`t know all others opcions, thank you anyway for all the information and links

What is your opinion with all those duks and corners?

The batch box designs we linked to can allow short or no risers, and can be well less than 90cm tall. You have to build a channel from there to heat your cooktop, or maybe the cooktop can be directly over the afterburn chamber. There would not be a barrel in these designs.

and...if I deside to do it with the barrel, as a conventional 6" rocket...can I cut the barrel so that it doesn`t overpass 90cm tall?

If you want a batch box, yes. If you want a J-tube, you will have reduced performance due to the shorter heat riser. This could be mitigated by a very good chimney, or by recessing the floor so the J-tube can sit below floor level.

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.

Thank you very much for all his advices

what do you mean whit a "very good chimney"?

You could do something like this

This is all masonry except for the cook top. I looked this up for a lady that wanted one which looked more polished. Her example was from Brazil with white tile facing. So you do not need a barrel just a cook top over the heat riser.
