Noticed an innovation that is new to me and solves a problem of heating the air for the P channel. Preheating the air behind the sloped portion of the firebox floor Is something I will try for my greenhouse mass heater.
I am somewhat perplexed by this adaptation of the P-Tube. I cannot tell from the available images if there is a tubular steel channel running along both sides of the combustion chamber floor from the door to the U-Tube, or if the U-Tube is a stand alone feature. I can see how it could be a stand alone feature as the gaps under the slanted firebrick will act as air channels. If both bottoms of the U-Tube are cut at a 45 degree angle, and there is an opening in the top of the U-Tube on the heat riser side, and the U-Tube itself is supported by the placement of combustion chamber firebrick, then I can see how this would serve the purpose of delivering fresh, pre-heated, oxygen rich atmosphere to the riser.
Been freezing this winter/spring in Eastern Oregon desert without a stove like this. I am not too sharp on this computer stuff but may I apply for the plans. I would appreciate the opportunity to learn more and plan to build before this fall and the snow flying. Thanks for your work and I hope you are planted Sea Berry (Sea Buckthorn) on the edges of your place there. A great hedge.
Gary, if you haven't already sent us a note via our website, please do. Just request some plan jpg's and we will send forth what we have. Love the Buckthorns. Many in place, and more yet to plant. Great source of Vit C, hedge planting, N-fixer, and wildlife interest. All the best!
Bert and Eva I have been thinking along these same lines and I think with some modification a lot of stoves would work. But my thinking is falling with is a door design that is cast which can makes it cheep if a large number of them are ordered. the door is the primary cost for this unit. If you have a stove in mind I can offer some help for modifications.
How does it works ? What makes it so efficient to cause the gas to burned completely before it goes outside ? What is the concept behind the design ? Does it have an EPA environmental approval ? Any off gas released into the room from the stove ?
So awesome! Thank you for sharing! The P-channel airflow into the combustion chamber is not shown. It looks like you have the U-shape resting on the bottom but is there a hole in it at the back of the batch box for the secondary air feed? If that is resting on the bottom, are you concerned with ash blocking or otherwise getting into the channel? I suppose the draft could be strong enough to blow it out. Really cool design man and so awesome of you to share the plans!
Yes, the airflow goes through the back, and we have had enough draw through the system to prevent any blockage of ash. We have been very pleased with its performance. Thanks for watching!
I am new to Rocket stoves and Rocker Mass Heaters. Thought I would be buying an efficient wood burning stove, but after seeing the RMH, I'm not so sure. Is it fair to say that the J-tube is the first generation of the rocket stove and the batch box is the second generation? Is this a horizontal feed of wood instead of a vertical feed? What size sticks or logs can be put into the stove? How long does a burn last? Apparently, the barrel that sits atop the firebox contains a riser and the smoke exits the barrel at the bottom leading to the top of the second barrel, where it exits out the bottom. What is the purpose of the second barrel and what is in the second barrel? Maybe you should patent this work. After all, you had the ideas, did the testing, and did the work. Why not get some financial benefit and some recognition. Great job.
I'm pretty sure this unit has a very tall riser, reaching nearly to the top of the highest barrel, the hot gasses then down draft to the bottom, make their way through the thermal mass bench, and exit up the flue.
Does anyone have plans and materials list for the Rocket Mass Heater vertical loading type that Paul Wheaton has in his home? Is there a list of installers of RMH for the United States, especially in the SE part? How much does it cost for average install and how would you install one on an elevated wood floor? Does anyone have house insurance with these heaters? Thanks!
You are thinking in terms of the limitations of a 'normal' radiant wood stove. The batch box is perfectly sized. In this system, the wood burns, + all the smoke burns, heating the thermal mass bench, from room temperature up to perhaps 200*F. Then the fire goes out, the inlet air slider is closed. The hot mass radiates heat slowly into the room over the space of 12 hours or so, at which time you burn another batch of wood to 'recharge' the thermal mass. If you made the batch box bigger, as the thermal mass came up to 200*F, it would absorb less heat. More and more heat would make it through the mass and be wasted up the chimney. The mass would also get so hot synthetic fabrics might melt on it, such as a polyester blanket or foam cushion. In this type of system, the stove's main purpose is to heat the mass, not the room air directly, while burning the minimal amount of wood. Having a larger batch box would just waste heat and wood.
Let’s see, the main box feeds the barrel behind it, this trapped gas exits sideways into tubing winding through the stone bench, that tubing comes back behind the pictured barrel and exits the roof. Let’s see main burning box has a hinged door, with main intake vent with close valve. The back leads intake oxygen through the rear of the box to the secondary burn barrel. The barrel looks to have a inner wall and outer wall? I may be off the inner wall dose not reach the top of the outer wall allowing a gap gas fills this area and only then vents sideways into the stone bench winding through it till exiting back near the top of the burn barrel and through the roof. The exhaust heats the stone and it radiates heat trapped from that exhaust. The secondary burn chamber and higher heat due to oxygen flow and radiated heat gives it a higher efficiency. Soap stone is supposed to hold heat well with a high efficiency.
cattigereyes1, You got it! As for soapstone it is pretty good but not always available locally, where as cob is pretty easy to build just about anywhere.
I do not know of a specific RUclips channel with that, but you most likely could get questions answered regarding that from people more informed here: permies.com/f/55/wood-burning-stoves or permies.com/f/260/rocket-mass-heaters. We wish you well, and thanks for watching!
I think one could just about make a go of this with the information as presented. But there is no detail on the manifold on the barrel, and I have no idea how big the cut out is on the P-channel where it meets the riser.
I've spent considerable time perusing your website, and I must remark upon what a fantastic farm you have going there. You truly are doing God's work in nurturing the land in a such a conscientious manner. Unfortunately, I am having difficulty finding this "How To" you speak of. Though, I have almost all the details worked out for my own adaptation. The dimensions of the firebox, as shown, and the door and door plate, I will keep nearly unchanged, although I will be building the bulk of the heater into a masonry bell, and forgoing the barrel. Curious about how thick your glass is in the door. At any rate. Thank you so much for the plans. This is going to be a fantastic addition to my home. Perhaps you could add the link to the "How To" in the video description?
David, the mass bench is 12'l x 3'w x 3.5'h. The bench is 18" from floor to sitting level, then cuts back about 18", then rises about 24" before cutting back the final 18". Also, their is a 4" gap between the back of the bench and the wall.
It would be wonderful if you actually supplied the plans. Yet so far I cant find any plans on your website or on your facebook page. How about a link? Or even supply the skp file for download. A blurry video doesnt qualify.
wi11y1960 the directions are clear on the video which hundreds have followed to date. Simply visit our website, go to the contact page, enter ur email and drop us a note. Plans arrive within a week. Good Luck.
wi11y1960 Seems like there MAY be a more polite way to ask for FREE Plans that likely could have been patented and profited from. I'd like to see a link as well if channel owner should so Choose to supply a link. THANK YOU ABC Acres for sharing what you have so far. Also- I'll be downloading Google sketchup today!
Hi There I do want a rocket mass heater in a home, I did hear I can better use a rocket bell version there, also these do burn even cleaner then a normal rocket mass heater and smoke keeps away from the living room. thanks.
Strange, though, that I haven't seen Peter mention anywhere that he had sold the rights to the Batch Box to anybody - in fact, he's been vocally opposed to "selling" the design, choosing to leave it in the public domain.

I may be misunderstanding the question, but the batch box design shown here has the feed box outside the barrel, except for where the intake cuts into the barrel, allowing the air to flow into the barrel and up the heat riser.

Joe, thanks for the kind words, we like to thin we roll but either way we're happy to help.
I enjoyed the music as much as this amazing stove. I was compelled to pull my guitar off the wall and pick along.
So much good can be done by your efforts, thank you for sharing and showing.
So sweeeeeerttttt!!! Will be putting this up in Philipsburg this summer :) We live on the cold side of the mountains , thanks again !!
Very cool, nice thing to share such great info without wanting to profit from it 😊
Thanks!
Excellent Job ! Thank you for sharing.
You're welcome!
THANK & GOD BLESS YOU for sharing these plans!!!
You are welcome!
What a classy looking RMH.
Thanks!
By the way, subscribed, so so many great topics in your back videos to explore . Thanks
Thanks Stephen!
thanks and very well made. Love the guitar music too!

Thanks for sharing the plans. Does the cob get hot enough to create a functional oven in it?
I am curious if an older wood stove could be used as a batch box as long as the outflow is in the back. Thank you again for great videos!

So was this your original design or were the folks at the permies site already doing this? The batch box I mean?
Nope, a design we acquired via Permies.com and a Wheaton Lab's class
Thank you.

Can you do a video on the rest of the bench/ chimney?
how does it all go together? all in all. quite vague.
Hi would it be possible to make a much larger batch box, so it could hold a lot more wood, just to have a longer burn time. Thanks

@@darrelljacobjr2120 Thanks
great work. a question. houw do you calulate de dimension of combustion camara?
and How do you get into the air from the P channel to the tower?
Thanks again for sharing this video. Can the .SKP file be downloaded from somewhere?
Zero, best I can do is shoot you some jpgs of the plans. Get me your email and I'll make it happen.
If you have it in sketchup, tell us where we can get the file. The extension of the file will be *.skp
Me to!

ABC acres I would absolutely like to have a copy of these plans. Boscoviusx@yahoo.com
I would like a copy as well. I like the glass top. Is anyone skilled in making these from your plans to selling them?
Let’s see, the main box feeds the barrel behind it, this trapped gas exits sideways into tubing winding through the stone bench, that tubing comes back behind the pictured barrel and exits the roof.

Hi.
I got classic stoves, and with to updated in RH.
You know à channel showing this ?

OK thanks lot ( french and with smartphone, not cool to search).
Have good begining of year.
I think one could just about make a go of this with the information as presented. But there is no detail on the manifold on the barrel, and I have no idea how big the cut out is on the P-channel where it meets the riser.

David, the mass bench is 12'l x 3'w x 3.5'h. The bench is 18" from floor to sitting level, then cuts back about 18", then rises about 24" before cutting back the final 18". Also, their is a 4" gap between the back of the bench and the wall.

We will keep that in mind, thanks for the suggestion!
ABC acres how thick of steel did u use
Justin, 1/4" steel made up the main box, with some 1/8" steel on some of the door components.
ok my batch box rocket heater is going inside my house...should I put the feeding tube inside barrel or set the barrel on top..
I may be misunderstanding the question, but the batch box design shown here has the feed box outside the barrel, except for where the intake cuts into the barrel, allowing the air to flow into the barrel and up the heat riser.
you understood right..if I did it like your design do I have to weld another barrel on top
Yes, although the barrels are attached by a gasket and clamp, not welded.
where do u get the plans
