Our fears of building our first one were very much alleviated by you guys. So thanks for that!!! This is our 2nd winter with our original rocket mass heater, and it's working great, but we've discovered that above all, it's a very "organic" process of learning what changes in design work best for your own situation. If I could give any tidbit of advice to anyone else who is making one, I'd say be willing to experiment. But don't worry, the principles are sound, and it DOES work. (By the way, it "rockets" best on cold and windy days when it's needed most, which is nice; also, we've discovered that it draws/rockets just as well with 10 feet of mass/bench as with 30 feet, but in our situation it definitely holds the heat longer with more mass....we started with a short bench, then decided that we could get more heat out of it with more. Again (to those who are trying it) don't be afraid to just build it, then be willing to fine-tune it later. In the meantime it will work, and you can make it better later...just like in this video. :)
One method I've seen is to have a bypass option so the air from the fire goes through the combustion chamber and then up the chimney, it doesn't go through the seating. This get it warmed a lot quicker and you slowly move it over to the seating piping. The result is stronger airflow and it's easier to light with less chance of it wanting to burn the wrong way.
I watched that, I am going to give it a try next month, maybe I can leave you a review video up on my site and show you how it goes. BTW your channel is awesome and really great job on your production value and editing. I really like all your stuff and you have a very cool family. Your dad rocks.
Thank you for the update. It will probably be another year before I build mine but this gives me a little peace of mind on how it should hold up after frequent use.
what an awesome wonderful idea and thank you for putting these rocket stove vids on for us all to see and enjoy, its a nice lil tid bit of info i am planning to use, when i build my own home be it cob, earthship, sandbag or whatever i finally am able to do.... in short please keep up the great work and awesome vids, God Bless you and keep your stick on the ice :)
Sounds like a few of us want a few more facts on your rocket stove. I am currently working on my stove. Now you got me wondering if my stove is set up right. Thanks for the info.
G Cox It has been a learning process for us. A couple years ago we went with whatever info that was available & today we wanted to test some new ideas. Bryson was reading about small rocket cooking stoves and he stumbled onto this 3 to 1 ratio. I would continue with your original idea and experiment. On Garen's in-ground rocket stove, he has a 3" shorter firebox along with the same 3 to 1 ratio and he claims it works better than our bench. There is a little more information on our webpage: mylittlehomestead.com/rocketstovereview.html Good luck with your project - keep us in the loop :)
Actually, apart from diameter, the riser length is dictated by primary, secondary and tertiary burn air supplies and their correct balance and, assuming a 3" ID, usually comes out at around 20" above top of firebox. Remember, throat should (must) be about 10% les sectional area to produce exhaust pressure. It also makes starting much easier.
Have you guys ever considered making a heated floor in one of your earth bag homes using a similar concept like how old traditional Korean homes are made. (Hanok) My mom used to live in a house like that growing up and she misses it so much.
My last place had warm-water heat to (cheesy) baseboard registers. A lot of the warmth came from the pipes to the registers, and they ran under the main hallway. It made the floors warm, which kept the house warm. Forced-air heat is convenient, but it doesn't warm up the house so much as the air in it. Just a different feeling. In that water-heated house, the air was warm because the house was warm. You don't mind running around barefoot.
Y'all are awesome, thanks so much for doing these videos, both informative and very inspiring to see you coming up with ideas, getting excited about them and bringing them to life!!
I really appreciate this update! I'm also interested in what formulas were used to calculate the specific elements of the rocket stove. Like, at one point "12 inches" was said - how? Why? What's the formula?! Thank you, another great video!
I did a short video on using the waxed cardboard that iced vegetables come in the produce department at the store. These can't be recycled so using them fro fire starting is a good up-cycle..You can light a piece and it will burn like a candle with very little smoke. The steady paraffin flame wil get the wood up to pirolisis so the gasses can burn in the burn chamber and riser.
I watch these type of videos more than the show... Actual feedback on how everything works. -Priceless!!! I thank you! I wish there were longer scenes, maybe with a little music, just showing the completed projects on some of your build episodes... After completing the earth bag room, and dragon mass heater, I wish you milked it just a little more, instead of "Done/Bye!" Great projects and work by the whole family, impressive!
Great video as usual , lots of very good info. Hope you had a good holiday season , can you believe it is time to select seeds for spring. WOW .... We do have some more winter yet I am sure but every nice one now is closer to planting time. Y=Thanks for another video ... Lord willing will see you later....... Blessings
I seem to have gotten addicted to rocket stove videoes and this is my favourite ;) one day I will build one myself, thanks for inspiring me I was curious, how hot can the bench get? I have this idea for a bath heated by a rocket stove but I guess I need a big one to heat a "ton-o-mass" and 100gallons of water up to about a 100°F
hello!! for lighting up the stove you can use ashes mixed with diesel oil in a medium-hard paste viscosity. just a spoonful will burn for a good time to light up the wood. greetings from Greece!!
Hello Janice! well the quantity is so small, in addition to the draft that is created while burning, taking the fumes towards the exhaust that i don't think that it is so much of an issue
Would be cool if you showed more of the fire. The shots showed, I can't see the "rocket" effect from the draft. Do you really have enough draft to create that intense heat? Shouldn't need to baby anything when the rocket effect is going.
Outstanding video......I actually recall watching this being built on UTube..must have been your channel. This simple technology is our future....we better get prepared....and soon.
it would be great if all dwellings in the US were required to have this method of heating. it would probably require a different method of fueling the fire based on location (maybe a small gas flame instead of wood.)
I am in the middle of building mine now. I have gone from 8 inch pipe through the seating area, and now to 6 inch, getting ready to go through the wall. Can I go from 6 inch to 5 inch before going through my wall? How about 4 inch? Thanks for all your videos....very inspiring.
nicely done We have been using wood heater only for 36 yrs in 2100 sq ft home now replaced heater in 2013 with same brand replaced 12" flue pipe every 3 yrs rest of chimney is brick, block, cement, fire brick, clay liner 21 ft tall. quick question -- How long will 55 gallon drum last ?? How often will flue pipe open to air be replaced ?? Will straw when dry in sitting area burn ?? I want to build one in my 1200 sq ft shop soon but 55 gallon drums do rust from hot / cold temps
Hey guys! Do you still have this stove? Just realized the barrelt is been cut to half? why was it? Great job btw!! Well done! I hope I can make my own rocke mass heater with about 14m long horizontal pipes. :)
very cool build and finish. So what are the important ratios to adere to? there's gotta be some ratios between burn chamber cross section and length and then height of the riser etc. seems like everything that come after the barrel can be as long as one wishes. has the shortering of the riser made the barrel less hot to the touch? or just more efficient? and how did you measure or evaluate the efficiency?
the only thing i didn’t like is the clean out, in my opinion there should be another one at the side, to see what the backside is doing. all in all a good video, thanks.
Question... could this kind of mass heater be used as a bed at night? I haven't seen anyone do it but it would be great to sleep on at night and use as a bench during the day.
we live in a 1947 house with oak hardwood floors. my husband and i have considered building one of these except for that fact. how would we protect the floor if we decided to build a rocket stove and bench? we don't plan on leaving this home anytime soon but if we had to pull this out for resale value.....well what are your thoughts on protecting the floors??? thanks for any info on this. love your post and videos!
After you light that little bit of paper, doesn't the warm air and flames rise straight back out of the hole? Why does it make a draught start going along, under the seating bench etc the long (and ostensibly, wrong!) way..? I don't get it...
Nice heater! I am interested in finding out the outer diameter of the outer barrel and the outer diameter of your heat riser with its inner diameter too, what size space did you keep the heat riser from the top of the outer barrel?
Yes I did subscribe. I am so enjoying your story and videos. Great ideas and execution. I wish you great success. Just one question though. What state are you guys in? Here in Texas, I'd probably not get much use out of something like that but would still love to do it some day.
Are you able to provide the details on how this stove was built...I guess I should say dimensions? We just purchased our little 3 acre slice of heaven and want to make a rocket stove for our tiny guest house. Love the videos and hope to see many more. Your family is great!
+mylittlehomestead check out this link of my rocket mass heater like yours i love it. i have improved on your design and got 30 second start ups and 6 hour unattended burn times. see how i solved the problem of condensation here. www.permies.com/forums/posts/list/52316
Forgive me, I’m not informed to what climate you are at- not looking for a location, but knowledge as to how cold your winters get there. I’m also wanting to know, does the rocket stove bench heat up a room really well, or just slightly? Do you have to have another heat source in the home? In other words, is the rocket stove just providing a little extra warmth? I love the idea. I’m trying to do research on tile stoves- those large old time stoves found in old European countries. Would this be similar?
Thanks for the update. Where is the research data that says a shorter riser & chamber are more efficient? I have been trying to search for it but so far cannot find it.
not an expert but it looks like your design would have benefited from a lower air intake to help draw air in and aid combustion. Thanks for the videos.
Do you have to empty the ash every day. I get tons of ash. Maybe mine does not burn hot enough.How much hotter does your barrel get since you shortened up.Thanks
I haven't watched your videos in a while. They were great when i did. I wanted to introduce you to aircrete. Its aerated concrete, I think you could come up with some good videos about it. Have a look on youtube. I like honey do carpenter's videos

Interesting, to bad in my region it doesn't get any colder than maybe 30 and that's only for like 5 days out of the year and the rest of the winter it can be any where between 38-60. It's so warm that my house doesn't even have central heat.
What type of heating system is in place if the whole family is gone for any length of time during the winter months? Can the house be left alone at all during the winter?
Great vid! Where did you get the new info for the riser height? All of the conventional rocket stove 'wisdom' that I've read and experienced says that higher riser=stronger draw/hotter burn.
Andrew Lund Bryson found the info in his research of small rocket cooking stoves. We are unable to re-locate the source - we'll post it if we can find it again :) We read the same thing about the higher the riser but have found this 3 to 1 is working good. It's all really just an experiment :)
we are in our 70s and built our rmh 3 years ago. it works perfectly. we have no complaints. no comparison to our old englander wood stove.
Yea!

You know, I've really been contemplating using this idea for a primitive concrete hot tub/bath and just using stonework and forms for the whole setup.
What are you waiting for?! You know you want a pile of dirt on your floor! :D
CLASSIC...! I just don't get that at PERMIES.COM they call this a "rocket mass heater" but here it's called an "in-ground rocket stove"...
that's golden

+Danny Boel
We do have pillows for comfort. Ummm... try out the bath tub idea and let us know.
That's a measure of efficiency that the exhaust is coolish...same reason why you can exhaust a high-efficiency furnace to ABS pipe which is amazing.
hello!!
for lighting up the stove you can use ashes mixed with diesel oil in a medium-hard paste viscosity. just a spoonful will burn for a good time to light up the wood.

Are you moving the heat into cob, stone or some type of heat transfer material? if so, the heat would be nominal at the wall.
Great review - good tips - thanks for sharing

Does your rocket mass heater heat your entire home and how many square feet is that ?
Awesome just Awesome 👌 👏 😎
love this
I enjoy your videos. Ive got a few rocket videos also :) I also like your earth bag dwellings :)
the only thing i didn’t like is the clean out, in my opinion there should be another one at the side, to see what the backside is doing.
all in all a good video, thanks.
Awesome.
Haha that last minute. I was just thinking wouldn't it be nice to have the mass of the rocket stove beneath the ground level.
Question... could this kind of mass heater be used as a bed at night? I haven't seen anyone do it but it would be great to sleep on at night and use as a bench during the day.
Yes. There are several builders that make these type. It would be warm.
That’s a common practice in Russia. There’s quite a few unique designs especially with children’s beds incorporated into the mass.
Sounds like the only complaint which wasn’t major was getting it going the first 1/2hour. Can a little propane wand burner be your answer?
we live in a 1947 house with oak hardwood floors. my husband and i have considered building one of these except for that fact. how would we protect the floor if we decided to build a rocket stove and bench? we don't plan on leaving this home anytime soon but if we had to pull this out for resale value.....well what are your thoughts on protecting the floors??? thanks for any info on this. love your post and videos!
my plans are to have rocket stoves lower than the floor and cob covered pipes under floor to heat it just like the bench kinfa like ondol in Korea).
sorry for the dumb question but wouldn't it be easier to just pile stones around the wood stove?
After you light that little bit of paper, doesn't the warm air and flames rise straight back out of the hole? Why does it make a draught start going along, under the seating bench etc the long (and ostensibly, wrong!) way..? I don't get it...
too cool, guys!
Would a matrix of copper heating pipes laid into the cob and connected to the hot water system work?
thank you for the follow up
I noticed the Mrs.is trying to start with a large piece of wood try using smaller pieces till coals are built
Awesome Sir. i Like, OLE!
Nice heater! I am interested in finding out the outer diameter of the outer barrel and the outer diameter of your heat riser with its inner diameter too, what size space did you keep the heat riser from the top of the outer barrel?
Yes I did subscribe. I am so enjoying your story and videos. Great ideas and execution. I wish you great success. Just one question though. What state are you guys in? Here in Texas, I'd probably not get much use out of something like that but would still love to do it some day.

I wonder, what kind of top coat/paint are you using? Thank you for answer.
2 inches (or a tad less) from top of the heat riser to the top of the barrel. If you leave a big gap... it won't work.
yes, What is the new burn tube formula you discovered????

Nice
Is your rocket stove over a poured solid floor? I keep telling myself that my floor joists could hold the weight. But....
Going through cob and gravel. I was just wondering if it would hurt the fire going from 8 inch to 5 or 4 in??
I'd love to build one but I think it would void my home insurrance. Maybe I could do it in the shed. Turn the shed into a Cat Cave.
Could you use the floor as thermal mass instead of a couch? So the same idea as the couch but in the shape of a cob floor thermal mass?
What type of heating system is in place if the whole family is gone for any length of time during the winter months? Can the house be left alone at all during the winter?
Can you have a side or angled fuel feed?
I like dirt on the floor!
Good morning, what do you secure, you paint this clay.
