thank you! pleasure to be here!

Glenn Herbert wrote:We can't tell how it will draft without knowing more about your chimney and the flue path to reach it. This is a very small unit you are describing, and it may work fine for cooking, but will probably not have enough heat output or draft strength to charge a storage mass. What is the size and character of your dwelling structure?


it will be placed in a small sunroom facing east 2,5x3,5x2m = 8x11,5x6,6ft that also acts as a fly brake in front of my tiny one-room house which is like 5x5x4m =~16x16x13ft (drawing attached)
aside from being able to cook with it it should also warm a slim bench that is 2x1x0,45m = 6,6x3,2x1,47ft and maybe the triangular space under the roof (where my night bed is) - the whole house would be even better
the stove should go two lengths through the bench/bed and then go up a through a smoke tube through the highest edge of the sunroom which is like 2,5m = 8,2ft measured from floor level and go up for another 1m=3,2ft or so

Glenn Herbert wrote:Is your proposed feed at the lower left door panel? It seems to be somewhat of an L-tube or possibly J-tube you are proposing.


thats right, i edited my original post, pasting it here aswell:
PS: i know that the ratio isn't 1:2:3 or even 1:2:4 BUT
i thought since it will be well insulated and i have two doors:
i could use the ash door to create a L tube to get it started (also convenient for cleanout)
and once it burns and has enough draft i can close it and switch to the upper door to create a J feeding tube OR i can load fuel vertically through the upper door close it again and keep the lower door open for air intake - should/could that work?

You will likely be better off building a separate heater for space heating.


my space is very limited so i try to combine it
what chamber diameter would you suggest for that space? all i can get out of the stove like in that batch design? space under the cooking surface is 28x50x41,5cm =~ 11x20x16ft should that be enough? (kind of nice btw - haven't seen it before)
i prefer the j-tube though - i like the gravity feed design

i would go for barrelbuild but it gets so tall (following the proven design - i would need a stool to cook on top) and i'm not sure if the top will be hot enough to cook wok menues and that kind of stuff, will it? -
also i would miss the baking oven -
so i still want to find a way to build a working hybrid - themed the quote hope dies last

thanks for your thoughts so far!

hello dear permies.com community!

i'm from austria and eager to build my first rmh that will be placed in my yet to build sunroom
therefore i wanted to convert a existing stove i have (for convenience of being able to cook and bake with it) into a rocket stove hybrid (for more efficiency and mass heat a bench)
since all rmh gurus are on permies.com - so i've heard - i wanted to kindly ask for your review and suggestion on my plan (i want to figure out if it will draft well enough with my current design)
the current stove looks kind of like this: (not my own - just for reference) http://thumbs1.picclick.com/d/w1600/pict/172291489812_/Tirolia-K%C3%BCchenherd-Herd-Ofen-Holzofen-Holzofenherd-Beistellherd.jpg


i have attached a picture of my current design which i want to integrate and replace the burn and ash chamber of the current stove with

some dimensions of the drawing:
feed opening:
10x12cm = 3.937x4.724in
burn "chamber" diameter:
10x12cm = 3.937x4.724in
burn "chamber" length:
27cm = 10.629in (till front)
15cm = 5.905in (till outer heat riser)
heat riser diameter:
10x12cm = 3.937x4.724in
heat riser length:
33cm = 12.992in
top plate distance to cooking plate:
3cm = 1.181in
exhaust circle diameter
12cm = 4.724in

the chamber and riser will be built out of 3cm = 1.181in thick vermiculite plates
the stove has a drawer beneath it - i could still go a bit deeper if absolutely needed (but prefer not to)
love to hear your thoughts!

kind regards,
dominik
