Rocket Stove Design Question

I have a question on designing a rocket stove in a 2 story log building. The ground floor has a hallway down the center (1.7m wide or 5.5 ft wide) with 2 rooms on either side. The second floor is just one large room with the stairs on the outside. The size of the building is 8.3m X 9.35m (27ft X 30ft).

Any ideas on the layout of the stove?

I was hoping to use one stove to heat the entire building. Is this possible?

I cannot help, but can help you precise what I think is necessary to understand your question.
(for when people come back from holidays!)

Do you mean if you have to do one upstairs, or is your problem to heat the 2 rooms?
(for heating 2 places, you will see my idea in a post I am going to open!)

Also, can you tell about the outside temperatures you will have and the bad or good insulation you have?
My stove in south spain will not need the same requirements as yours!!!

The log building has 2 floors with stairs on the outside. The logs are 17cm diameter.

The first floor has a hallway that runs the length of the building with 2 rooms on either side. The 2nd floor is just one big room.

The climate is a little harsh (-50C) as we are in the countryside in Mongolia. We are doing a cooperation with a school. They are very interested in what we have shared about the rocket stove and are interested to see what it can do here in Mongolia. I am needing some assistance as I would like to get it right as we do not have a long time to play with this before winter sets in.

Is your problem to heat the 2 rooms? I think that the door location is important.

You can think about the central europa system, very close to rocket stove:

They are called kachel stoves. You will see a plan on this link.
they were just huege and usually made at the same time of the house, as you could heat a wall between 2 rooms.
They can be 2 tons...

With so little insulation as with logs, I guess you have to put 2 stoves if they are not big, so that you can make warm beds in the 2 rooms...

Also, you can consider making a warm ground. As the heat goes up, and as the ground brings better insulation than log, you can have a warmer room.
You just make the ground as you would make a warm couch...

The only thing I hesitate, is to know wheter or not the smoke can go DOWN.
I mean: is it possible to have the stove at ground level, or do you have to dig it so that the pipes under the floor are at the same level as the stove?
