Tiny stove

Hi. Years ago I got the book thinking in a rmh for my workshop. Now, I realize the surface of the workshop is really tiny, about16 sq. meters ( 45 cubic meters) there's not enough space for a big project...

I change plans now. Perhaps the easier solution is to buy a tiny stove. I don't want to use more than 40cm x 40cm for the stove. In Italy I found one at 200 euros which I like, but it's out of stock.

If you see in the picture attached, there's my daughter near some bricks for the new stove-project.

Last year I made one just without thinking to much and worked nice. In the summer I broke it thinking in a better solution.  This time I would like to have more attention if somebody is enough kind to give me some feedback to have a nice and easy plan.
Cold is coming.

And if somebody love violins, it would be a nice change to share info too!!!

Thank you very much.

Hi Paolo, that is a very small space and a small woodstove might be easiest, but I would recommend something similar to the "cyclone batch rocket mass heater" built by Kirk Mobert at Wheaton labs. You can see some great photos at https://permies.com/t/71576/tiny-house-rocket-mass-heater. They have had some great results with this stove and it seems simple enough to build.

For specific dimensions I believe the build follows Peter's 4" batch rocket stove found at http://batchrocket.eu/en/. This is nice for a small space since the mass is vertical--limiting space--and it doesn't have a barrel.

Beautiful violins by the way--what an awesome looking workshop.

Hi Daniel.

Thank you for your suggestion.

I really like that Cyclone batch RMH. However, its size is almost double of my available room for the stove in that position. I could move it to the opposite wall (which I have to free from some tool machines) but I will have a colder windows, and I work near them to have natural light as much as possible.
I am hesitating a lot. I know.

Thank you for your compliments!
I moved to this place in july, when I started the business here. As I have to work at the same time while creating the workshop, it's still in constant moving, changing tools, shelves and desks searching for the best result in that tiny space...

Perhaps it's potentially good looking, but I am not still satisfied.
