So, here's what has been rumaging in my head lately.
I have some of thoses porous, "pierre du gard" which we use for the surounds of chimneys. All in yellow on the drawing. The big vertical slabs are some firebrick i have all the rest seems very obvious. Just missing the square barrel. A friend from an internet forum is suposed to send it to me soon. Otherwise, i have all the components. That would feed in the half barrel concrete bench i've made. And go through a 11m chimney. I have an isa of 3.2m² if i put the half barrel bench behind this. A bit small. But i don't know how to fit better. The idea behind this is "all dry stacked" and helf by tying wire where needed. I might put few screws and plugs in the sides. Don't know. The bottom space in between the stones will be filled with lose vermiculite or perlite. Actualy, about this, what would be your opinion. I can find both at aproximately the same price. I find the vermiculite all right. Never worked with perlite.
Ehrmm... Why is the port larger and the p-channel shorter? This way, there's more air coming in at a lower temperature. The bell should work like that but the half barrel is much lower than that isn't it?
Thoses refractory flues i have are about 18x18 cm with rounded corners. IIRC, i took 70% of the square size as an actual measurement for the flue size. Trying to account for friction. But still, it makes an horendously large port for the batch box size. I can't get the rounds anymore. I have the four squares nedded for this one. There's a few left in the stock at my Italian hardware store. And after, i'll have to look for something else. On this one, i realy don't want to make any mistakes.
The half barrel entry will be at about floor level. 3cm of concrete below. , and i have the option of using either 150, 160 or 180mm i have in pipes for the moment. I also have few bits of stainless 200mm. You think i should lower the floor for the rocket core down to the ground? It will be real low then. If only i could do a trench in the 60cm wall behind me, and fit the flue in there. I would have the best accumulator/Mass in the world.
Thanks for your reply.

vesuvius: Do any of you have experience with using the glass from home oven doors on a rocket stove? I'd like to have a viewing port on my stove but don't want to fork out for new ceramic glass. Any thought as to whether it would take the heat of a rocket stove?

deadstarsstillburn: Hi there. I was directed this way by folks on the Permies.com website and am hoping I can get some information on how a total newbie can get started designing, siting, building, and not-dying-in-a-horrible-house-fire with a new RMH in a 160-year old home

deadstarsstillburn: The people over there recommended either a 6" batchbox or an 8" J-tube. I don't know what those are but am going to try to figure that out. What I need is a blueprint that I can scale to fit the need for my house. I have something likne 5000 square feet

deadstarsstillburn: but I do not need to heat all of it by any means. probably only need to heat half of that, maybe less.
Oct 21, 2020 6:53:15 GMT -8
deadstarsstillburn: moreover, the house has 3 storeys (large attic) so I assume if I get very efficient heating on the ground floor, that will go a long way toward heating the upstairs as well, no?
