Rocket stoves are superefficient wood-fired stoves that can easily be built using readily available and recycled materials. In this video, Nathan and Tony describe two different rocket stove systems, detailing the inner workings of the stoves and their unique ability to store heat much more effectively than traditional wood stoves.

I really love you guys. Your energies are so attractive and inviting. I am so happy with the work you are doing and then promoting by making videos. You will help change our world with every person who sees this. Love, Bryan
Functional and beautiful. Someone in that house has an artistic flare.
mmm on a cold foggy day like today that bench looks dreamy
Very cool! You guys - it is so impressive what you have accomplished since 1998 when I visited!
10 years ! Wow can't believe it's been that long. Maybe time for another visit!
I want to let you guys know that I've subscribed to your channell. You are doing such great work to get the word out about Dancing Rabbit, Sustainable Living and Intentional Community. Great job!!
Great video showing a good idea.You are thinking outside the box and seeking new ideas about how to do things better. You are also taking it to the next step by building it.
My two gas fired, forced air heaters have you guys beat hands down for comfort and fast heating.
Yes, safety first...protecting family/loved ones/and self is paramount :)
Thanks in part to this video, I was empowered to design / build my own rocket heater, which you can see by searching for :
Rocket Mass Heater
One *vital* thing that isn't mentioned here is that the barrel section is actually a well-insulated reburn/combustion chamber that operates at ~1800F, *completely* burning all volatiles. The intense heat is what causes the 'rocket' effect (i.e. hot air rises, and the hotter, the faster), and guarantees that CO levels are less than 10 parts per million in properly designed stoves, because the fast moving stream of air ensures that every carbon atom has *lots* of oxygen atoms to bond to.
awesome! I think I may build one this summer...thanks for sharing this info :)
I didn't say they don't work. They do indeed work very well. My point is that thin mild steel corrodes under high heat and moisture conditions. The units shown run thin metal flues horizontaly for great distances increasing potential for moisture induced corrosion and flue leakage. The hazard is increased because they can't be inspected for leaks. Address those issues and all is gold. I should have written a second comment to make my meaning clear. Thanks for prodding me to clarify.
Thanks for posting this is very nice
Great, thanks guys!
The plus of having a rocket stove is that it's so fuel efficient, it gets so hot that creosote and smoke are hardly a problem.
very impressive, i really like the larger/taller infeed area of the first stove,allowing for that large half-log to be fed in, looks like it would burn for hours on end without needing to feed more in each hour or so as other designs ive seen.
about how long does that go for generally speaking? also see theres open space below,and a front hatch(for fire-starting and cleaning i presume?)
peace from mississippi
good idea, building up the thermo-mass around the barrel ! ;)
cool idea man
Base load power plants still (for the most part) depend on coal, a non-renewable energy source.
They're about 31% efficient, which mean 69% of that fossil fuel is wasted. Plus the fact that it costs around US$1300 per Kw just to build. A energy satr rated fridge still uses about 400 kwh/yr.
The great thing about a rocket stove is that it's so energy efficient due to the extreem heat that there will be hardly any pollutants left.
well done.
Love it.
You don't get creosote and there is very little ash left behind. Most of these stoves have some kind of opening to vacuum/shovel ash from them, like the low door on the front and often another somewhere along the exhaust side. These things burn so completely and efficiently that there's virtually no smoke exhausted. The design makes for a complete burn of gases in the riser under the barrel.....no creosote becase there's no smoke. It's just smoke smelling vapors at the chimney end.
That's what they're afraid of... and of all of us becoming free of course!
It looks like a 55 gallon oil drum. People will plead to get you to take them aware.

@RA59 there is a strong downdraft pulling air down, hence the rocket name :o)
Yes, you could build it with those items. Mine is built with firebricks and red bricks. The bricks that have the 3 holes in them. So far, Ive had no problems with it.
I wish I could come see one of these in person so I could better understand it...
My only concern with most of the designs I have seen is how do you properly clean the flue passages that you have encased in cob? The bench and all other pieces of thermal mass are great, but the way I see the installation, if the flue passages become clogged with creosote you have to destroy your bench to clean them out.
that rocks. making the flue long and packing mass abound it is the way to go. i always wonder why people vent it out as fast as possible.
how do you clean out the ash deposits in this installation? it looks pretty impenetrable..and what kind of building permit issues do you have with this?
man that is great! what is cob? cement or mud?
If you put a long piece of wood into the feed for the stove, what prevents the flame from traveling upwards along the board and into the room?
nice explanation. good vid.
In researching cob I have always wondered . When you oil it, does it ever seep back out? In the case of your bench does it ever appear on your clothing when you stand up. Also ,do you have to "re-oil" your cob every so often?!!
G'day I Love this kind of stove heater! I've been looking for a stove Heater to put in my 33ft by 30ft shed mainly to heat this area I think this kind of heater stove will do it. thanks for posting video's. do you think it will do the job. Rod
I see cracks in the cob in both rocket mass heaters. Do you ever have a C0 detector in the room to see if you get any carbon monoxide?
the name got my attention
I would be interested to see a fire get started in that second rocket stove. It looks like it would be difficult to achieve a draft during startup because of that long horizontal run. Until the vertical part of the flue gets hot what will draw the draft?
I would rather have a masonry wood stove rather than rocket stove for maintenance reasons and the stoves work much in the same way.
Is the advantage of continuous wood feeding, say, during the night, unique to only the 'rocket stove'?
Good idea! Well done! Just watch your back because the power companies will be after your ass!
Makes me wonder why there arn't commercial rocket stoves that are avalible, I mean it might be a fun project, I just don't want to do it. But I'd probably buy one if reasonably priced.
Your rocket stoves seem to be a reinvention of something that has been around in Europe for a few centuries. The Kachelofen or masonry stoves seem to be the exact same thing. They are a very efficient form of heating with wood. They have a rather complete combustion and they run the exhaust through channels in a masonry mass, heating that mass which then gives out radiant heat for 12 to 24 hours. IS the rocket stove not the same thing?
@birdland5 the combustion is much hotter, and alot less wood is burned, cleanup shouldn't be needed for a long time
Great vids....informative. I live in a 3 bedroom mobile home in rural southern Michigan and want to slowly get off the grid while educating myself. I have searched high & lo for vids/info on mobile home applications re: safety & the load weight on the floor. Any suggestions? I have "open concept" living area so would put in corner of living room. Thanks & look forward to following you. PS: My huge concern is insulating stove from floor/walls so no burnt down house.& 2 much weight on floor.
do you have a instruction for building this stove?
@shartne clay,sand and straw
Watching this video helped me learn more about how to build my own heater, tho with my own design differences. Check it out. Search for it here on RUclips by searching for
rocket mass heater
how do your neighbors feel about the exhaust gases . . .?
Carbon Monoxide?
is there anyway to keep it from cracking? I love the smooth look
Yes, thanks for asking! The material around the stove is just a natural plaster, and with natural plasters, if you add more sand it will crack less. You can learn more here about the basic ingredients of natural plasters and their function: www.buildnaturally.com/EDucate/Articles/ClayPlaster.htm
drecovillage wow thanks. you guys have a nice Christmas when you get to it.
How much to have you design and build me one ?
Rocket stoves burn so efficiently that there is almost NO smoke, NONE
@mrJOEmann @birdland5 its sopose to burn so clean there is no soot produced or ash, the only thing that should be coming out of a good rd CO2. ocket stove is steam an
@shartne Cob is>Cow shit .Enjoy. Basically its shit stucco.It does do the job though, but not a pleasent thought.To me it just shows that everything is usefull,and I am not a tree hugger...lol
does ash build up in the long horizontal exhaust pipe?
Thanks for your question Gary! Yes, ash can build up in the long horizontal exhaust pipe. Usually, most of the ash and fine particles collect at the bottom of the upside-down 55 gal drum, and a clean out is usually built into the system there. Most diagrams will include clean outs for both of these locations.
@lakewood85
Dude, really? No shit! Did you build the air heaters yourself from scrap, or are you leaving a major carbon foot print? You're still dependable on being on the grid and paing a gas bill.
The first guy looks like hes freezing. That stove must not work.
дайте переводчика!!!
If you did research, you would realize that cow shit was used in cob by some, badlegend1 was joking but that doesn't mean he was wrong, just exaggerating for jocular effect. Now who exactly is the fool again...?
lol, if every one did this the power companies would go bankrupt
It's only cow shit if you put it in there. LMAO! It can be nothing more than sand, straw and clay. That's what I'd recommend anyway. If you're feeling frisky make the stove from recycled bricks and concrete.
Ecojizzmops.
why are you wearing insulated coverall's and gloves in the house, how in the hell are you going to clean out the chimney, it still has to be cleaned it is not 100% efficient, why is the big cracks in the cob. It is cool looking but there is better more efficient way's of heating. what if you don't like cob i live in the mountains a friend of mine has a new home with rocket stove, i have old house custom built stove. His house is freezing compared to mine and i burn 3 cords a year compared to 8.
Dude, actually you would be better off to heat with electricity. Base load power plants generate all the power you'll ever need and then some. By the way keep pumping wood pollutants into the atmosphere you dope.
