Hello: I am new in the foro and I have been searching for bypass desings without results. i am planing a bbr of 20cm with a bell bench and a smaller bell upstairs. I can imagine how to make the bypass before the bench, but I don't find the way how to make the bypass into the usptairs bell. Where can I find bypass designs examples?
I don't have any specific bypass designs but maybe you are looking for how to do it. Like where is the bypass and how should it function in a double bell system that is also situated in two different rooms.
Have a look at this thread In this build, it's done with just one valve to bypass part of the first bell which gives also some control over where most of the heat is going to.

I would second vortex's recommendation of a pivoting plate type of bypass. If the chimney passes through the upper bell I would imagine a bypass that blocks the the chimney and forces the gasses into the bell. You would of course need a second connection from the bell to the chimney for the gasses to return.
Another idea would be making the downstairs bell larger and pass through the floor into the upstairs thus eliminating the need for the bypass at all.
Thank you very much for the answers. My question was more in the way that Peterberg says. I cannot make the first bell hight enougth to arrive the upper floor for structural problems. My question is more how to make the upper bell bypass. The idea is that from the lower bell the chimmney was trougth the floor of the upper bell inside it near the top, and then leave the hot gas fill the bell untill they arrive the chimney that go out and that start in the lower part of this second bell. Then, how can I make a bypass in order to make easier the gas was the most directly as possible to the chimney that go out of the roof? Sorry, the english is not my mother tongue.

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?
