#permies #rocketmassheater Maybe not the neatest pics, but one shows the brick bell and wood feed. The other shows a rack I threw together to hold maybe 7-10 days worth of wood if burning 1-2x daily, and the brick bench.

If/when I redo it, will rebuild it as an 8” system instead of 6”, and make the bench a little longer but a fair amount wider, to capture and hold more heat. So efficient though! 😍 My wife even says it is really easy to light and after not being too sure about it in the beginning, now she just loves it!

Cool! Looks nice and tiny, I like the design. I have a tiny house but I would also choose 8" I hear Paul Wheaton repeating how much better it runs, and, am hoping for the added mass to help cool in summer. But we'll see, still sokewhat further in the future...

Paul’s 8” system in the Fischer Price house IS very nice! I spent two weeks at Wheaton Labs in 2019… both 6” and 8” work well. J-tubes are more efficient and (I think) easier to light than batch boxes.

Below 4-5” systems are MUCH finickier… too much laminar flow/resistance along the edges of the path of gas flow. 10” or larger gets TOO hot…

cool! 😮 I wish to visit Wheaton labs someday, it is a bit harder coming from the EU. Else I would hve been an ant for many years...

Yeah, I was initially thinking about a 4" system but I dont need that extea finiky whatsha-ma-call-it. 8" is proven and just works, so I will go with that. My next steo in this is to build an outside J-tube #RMH but need to get the riser materials first...

So many wonderfull projects, quite addictive, and each steps makes me pollute less and increases my happyness.
