47. Rocket Mass Heaters: A better burning wood stove
The rocket stove takes our fascination with fire and bends it 90 degrees. Discover the secrets of building an amazing Rocket Stove from Ashley Lubyk of Dirt Craft Natural Building and Rob Avis of Verge Permaculture. Learn more in our full blog, radio podcast and photos: www.greenenergy...
It's a hyper efficient wood stove that uses far less wood to get a far more effective result, whether it's heating or cooking. It grew out of efforts in developing countries to build a more fuel efficient, safer cooking stove and it has since morphed into an idea that could eventually replace your furnace. Learn how it works this week at Green Energy Futures.

look around, there are a lot of people into this. There is a community out there that we were able to contact...(online community btw) that had plans that we were able to get. They were either free or really cheap. We adapted them to 10 inch stove pipe and full 55 gallon barrel. Used 2 times the amount of clay/mass too. Works.

I've built a RMH myself with no piping in the mass....just a void or 'bell' which allowed the heat to stratify before gases exited the outlet flue. Very efficient and inexpensive, but heavy in labour. Get the books!

Now that you've had it in for a while, do you think that its better without installing pipe in the mass or with the pipe in the mass of the RMH?
rocket mass and rocket heaters are quite affordable if you have the time to scavenge...and even if you do not, they are cheaper than the store equivalent efficiency. Installed one with my father in law in the in-law's new home. Works wonderfully. Adapted the plans from someone in the rocket mass community...apparently they do exist. The clay cost less than 400, found the bricks, had the drum...the last things we needed was some 10 inch stove pipe, both double and single walled. I would say around 1200 total for a beast of a stove. It is large enough to heat 2200 square feet, fired 2 times a day in the dead of winter. It seats 3 people comfortably(because it is a freaking couch)....! Anyway, I really wish we could have installed one in our home when we were building it years back, maybe one day. In the meantime we have a Mohawk(from the 70s) which is a top draft stove which is amazing. Not as efficient as the rms but close.
I like the comment that sustainability shouldn't be unaffordable. It seems like most green energy things are outrageously expensive.

Would you work for free? I wouldn't expect anyone to, employees cost money so there has to be some way to pay people to work, as well as pay the bills too. Free-enterprise is the best way to keep greed under control, when businesses must compete for customers, it forces them to keep production costs at a minimum in order to maintain status. Socialism only works if an outside contributor is present. Talk to anyone from Cuba about how life was there.
To answer a few questions: - How a rocket mass heater works: As we all know heat rises so lets skip that discussion and go onto a more in depth explanation... The smoke/heat take the path of least resistance which is up the larger diameter riser (taller portion of the J tube) and out the venting pipe. In doing so a vacuum is created which pulls air into the smaller lower opening of the J tube creating a high velocity airflow which supplies more oxygen to the fire thus creating much higher temperatures resulting in a very efficient burn of the wood which leaves minimal waste (unburnt wood) resulting in minimal amounts of ash leftover and a very clean burn. All in all more energy is extracted from the wood therefore less wood is needed. The gases that would typically be in the smoke almost don't exist in a rocket mass heater. This is due to a very efficient burn of the wood. The more efficient the burn the less harmful and cleaner the exhaust becomes. This applies to anything that burns. Just a FYI: Wood doesn't burn it's the gases in the wood that burn and to release these gases heat is needed, the more heat you have the more gases are released. These gases can be captured and used to run an engine and can be used in many other ways such as storing it in a holding tank (propane tank) and using it the same way you would use propane or any other gas. This method is called wood gasification, if you want to learn about wood gasification just look it up..

I know that in most places where wood burning stoves are permitted, there often is a chimney cleaning requirement, in my experience an annual requirement. My question is, if the flue gasses run through horizontal pipes to heat the thermal mass... how would one be able to access those sections for the sake of cleaning? I know that 90° angles are problematic in the sweeping process. Also someone should investigate the specific roadblocks for permits in residential situation. Certainly the permit process is a pain but usually if one can prove reliability and safety via a study or engineering report, inspection agencies would approve their use. (That is, it can be difficult, but it can be done.)

The exaust comes out the bottom the super heated air is rising out of the riser and causes positive pressure in the barrel which pushes the remaining air down through the exaust then the exaust starts to create a suction that causes the stove to rocket
So, if you have been away for a week and your house is freezing cold this will be useless as it, I guess, will take about how many hours for the mass to heat up? Other than that, I love it and would use it daily.
@ashfrodesen9126

that's the point of having the barrel produce radiant heat. it gives the instant heat you want, very soon after you light the fire, easily comparable to a normal wood stove. the mass only collects heat that would otherwise be leaving the chimney. you cant do that on a normal wood stove because a normal stove doesn't get hot enough to burn the creosote before it can condense on the stovepipe. when the exhaust leaves the barrel, it is mostly nitrogen, CO2, and water vapor. this hot exhaust is pushed out through the mass by the force of the super heated fire in the heat riser. by the time it leaves the house, it is 100-200 degrees.
I understand the concept of the heat being sucked into the barrel but wondered, when first firing it up, how does the heat and smoke 'know' to go into the barrel and not straight upwards into the room.

I have a rocket stove heating my cabin here in Alaska I used 1 cord of wood last winter. While my design is different, the concept is the same. Believe me, any flame at all under that chimney will start the process. Once heat starts to rise, the fire increases and draws more air. I have occasionally gotten some flame outside the firebox and it sucked it rite in. my cabin is 10x14., if there was even the slightest smoke being introduced into the room it would be horrible.
This looks similar to a Dakota dugout.
How do you clean up its internals? But yeah, one can't buy sustainability.
I am surprised that been years I seen this rocket stove videos, none of them every consider putting metal fins on the barrel for more effective heat radiation, with an opened bottom and top case wrap around those fins, first it's safer to prevent people accidentally direct contact with the heated barrel, second, the cold air will suck into the gap from bottom of the casing, passing though the fins and heat up.(passive airflow)

the barrel cools off quickly when the fuel runs out , warming the large mass stores the heat that is released into the dwelling over many hours . instead of going right up the chimney like a conventional stove
a masonry wood stoves can be made easy or hard to clean, load 2 or 3 times a day. the rocket stove is open like a fire place when fires out.
Could a large rocket stove be built outside and the heat transported in under like in a crawl space to warm up underneath the house

There are multiple clean out ports. One is at the bottom of the J tube (the bottom where the wood sits), the next is right next to the exit pipe on the bottom of the barrel so you can clean out the barrel, the others are placed along the stove pipe ducting that is surrounded in the cob mass. The easiest way to clean out the ash is using a vacuum such as a shop vac. There is very minimal ash build up due to such an efficent burn, and the ash that is loftover is a very fine powder.

The insulation on the heat riser (inside pipe) is to keep the exhaust gasses as hot as possible for a more complete combustion. More complete combustion = more heat generated.

It mostly collects just where the pipe exits the barrel, the manifold area. Since it is 95% efficient, there is very little ash at all. But you can build a cleanout there, and in other places. Normally some kind of metal screw cap. The barrel normally can be removed, or some people use just enough of a second barrel that it can be clamped to the main barrel with a barrel connector, that gets you pretty much inside everything.
One thing I haven't figured out yet is how do you take ashes out of the stove. What I see from the design, you do it by letting the fire die down and then you stick a vacuum cleaner tube down that tiny opening and suck it all out. Other than that, my grandma could really use this.

I would mention to anyone wanting to learn more to also stop by www.permies.com they have an extensive forum full of all kinds of designs and ideas for RMS and Rocket mass heaters.
vid is saying it is clean , efficient burn - this is to do with air flow - and suggests complete combustion. Jake Trautman is right. Carbon monoxide is product of incomplete combustion when there is not such a high oxygen:fuel (wood) ratio , (so something problematic would have to have happened to the inflow of air, a blockage) . precautions are same thing as any other burner - ensure good ventilation in your home, and if you think it is needed, then use monitors for CO gas.
I'd love to have one, as $375 month utility bill has breaking me.
The truth is this dates in its basic essences to the Roman Empire. That had a floor heating system called a "Hypocaust"
I do believe that some have been successful at getting "permits" for their builds here in the "free" usa.

I can tell that these people who have talked for a long time don't really understand why it works as it does. Quite a few years ago ( 7 ) I put my brain to understanding how this works and how you can attain these efficiencies. I understand this process. How can you go from burning 6 cords of wood to maybe 1 to 1 1/2 for the same heat when the existing stoves may claim an efficiency of 80% lets say. There is something wrong. But I can tell you the rocket mass stove does just that.

It basically "works" because it dumps its heat energy when it comes out of the inner flue and encounters the 55-gal drum. Not only does it "dump" its heat energy, but the (realtively) cooled air sinks, drawing the hot combustion air upwards. If you insulate the drum...you lose the draft. Ideally, you should insulate the inner flue, so that no heat is transferred to the gas in the 55 gal drum portion...I don't see them doing that here.

Existing wood stoves may claim to be 80% efficient, but they are just 80% MORE efficient than the last piece of junk ineffecient wood stove. Not 80% out of 100%.

Darrell Jacob JR - close... Actually, they are 80% efficient at combusting completely and turning the fuel's available hydrocarbons into heat... The fact that they send a huge portion of this heat out the chimney as 500+F exhaust to maintain stack effect has no bearing on the "efficiency" rating. It is in no way claiming that 80% of the embodied energy in that fuel before burning will wind up inside one's home. That (highly important to real world value) factor is not a part of the EPA wood stove "efficiency rating" program. It's all about cleanliness of combustion, and the rocket design has them beat on all fronts right up front in the super efficient primary and secondary combustion it creates. Well designed/built Rocket mass heaters create 90-95+% combustion efficiency for most of their burn cycle, AND scavenge most of the heat from the (MUCH) cleaner exhaust gasses, before sending them out of the building... And have a "real world efficiency rating" that is probably closer to 80%, wheras the "80% efficient" (at combusting the wood) stove in my living room probably has a real world efficiency (net energy from the wood burned kept inside the home) of closer to 20-30% I clarify this mainly for others as I know from other comments that you have an intimate knowledge of RMH's and their construction/design principles. I just wanted to explain the facts for people used to using normal wood stoves and talking about their "efficiency ratings", who have not experienced the real world difference between the two... Which stated simply is: A properly designed and homebuilt Rocket Mass Heater, burned a few hours a day, will keep you warm (70+F) 24/7, on anywhere from 1/4 to 1/10th the wood of a "high efficiency rating" modern wood stove.

bcubed72 - the dumping of heat energy at the barrel is the second half of a two stage thermosiphon... The first stage is the rocket's highly insulated burn tunnel and riser tube. At 3000+F in the most highly optimized designs, that 3-4 foot burn tube creates MUCH more stack effect than a normal chimney of that length due to the huge temperature differential... The barrel then shrinks these gasses back down to flow through the exhaust at only somewhat higher temp and velocity than the intake air being sucked past the fuel.

Actually, it's still 400ish*F coming out of the barrell...it's the mass that sucks the heat out to bring it down around 100*F.
There's only one problem with this and NO ONE ever addresses it. Why don't you burn outside air, instead of using warm air for combustion? Run a pipe from outside to give it the oxygen it needs? Otherwise, you'll have to allow fresh, COLD, air inside.

there are several iterations of rocket stoves some have outside air intakes . I have seen dozens of videos on rocket stove installations. The take away on air intakes, they need to be insulated and should have a good damper for control of the fire " very important" in case the fire has to be put out in a emergency. and a screen to keep critters out . If you have a very air tight dwelling you will certainly need out side air . and when the fire dies out, air needs to be turned off so out side air that comes in through cracks and crevices , and under doors wont be drawn so hard, cooling off the Dwelling , and the mass. The concept of the RMH is sound and if care is taken in design and construction. you will be rewarded with a system that is way greener than the old oil burner.one stove is indeed certified www.rocketheater.com/customer-reviews-and-special-thanks/

If you have either money or welding skills you could use much heavier metal for all of it and make a unit which would last a century and never corrode through or pinhole and leak. Use Schedule 40 pipe and mild steel plate for the whole thing including ductwork since unlike a conventional stove, the creosote is consumed by combustion. Use bolted top covers with gaskets on the barrel (and use stainless bolts) so you can clean it out every few years. Bonus is a plate steel top (if you have the bucks, go for half-inch!) has ample thermal mass on its own and if clean can be uses as a stovetop too. A lip around the edge wouldn't be hard to do. If you TIG you could make your barrel from a couple of stainless steel beer kegs, and you can also order stainless steel 55-gallon drums if you like a conventional barrel but want it to outlive your grandkids. See your local welding/fab shop. Show them designs, and they can translate into serious metal. If you visit welding forums you'll find some beastly stoves and shop heaters built by skilled pros.

build one first in garden to perfect it mine took about 70 bricks, and a drum go to a ducting suppliers they will have different size flange connectors ,the reason there is no code approval for these stove is the same reason there would not be light bulbs now, no current code or approvals means no change , keep on burning nuclear fuel , oil or gas or electrickery which is made from the former at an efficiency of 25% if were lucky,but wood is also finite in supply you got to grow it to burn it

Trash incinerators using a fluidized bed burns at 1700 plus degrees most generate steam which drive a turbine for electric generation . many maintenance issues from acids in metals , and plastics you would have those problems as well. there are safe guards on commercial applications that a simple rocket style stove wouldn't have. Not recommended .

@jamesjordan8399

most of the ash is in the burn chute. and can be scooped out before each fire . the fire burns much hotter than a regular wood stove as it enters the burn chamber and burns hot enough to vaporize creosote . not much is left .except gasses
"Flue gasses are contained by this barrel...through stove pipe and into a manifold and then through stove pipe that's inlaid in this ????? bench. So all this thermal mass is sucking the heat out of material, out of the flue gasses before it exits the building" WHAT???? Where do the gasses go? If they go into the clay, how do you know that they don't leach out?
@chop98

The gasses go into the burn chamber first to be burned up, snoopy. It's hot air/stream that travels along the thermal mass which has a pipe ran through it. I'd imagine this can't possibly be your first rocket heater video... is it? If it is, then by all means, do go and view more and the concept will be explained in detail to you. I've considered building one of these for some time now. Might even try one soon. :)

snnnoopy Correct. If you make your stove properly, the extra air intakes will act to feed the pipe and make a super burner. They're acting like afterburners. You can make 'em out of regular bricks for a small one in your backyard to try one. I would suggest some fire bricks though. I've watched so many videos and read on this stuff it isn't funny anymore. :) This concept seems to be proven. Besides... they use the same theory to burn off leftovers in coal factories too.

I've watched 50 or so videos, read the book and I don't think anyone has explained it until it occurred to me: the inner burn chamber must be insulated while the outer barrel is not. As the hot gas goes out of the top of the burn chamber and contact the cooler outer barrel, the gas will cool and therefore condense, or take up less space. As more heat ecsapes the outer barrel, the more the hot gas from the burn chamber will push. This creates the draft, or the force that moves the gas through the stove. So what you can do is have horizontal flue pipe coming from the bottom of the outer barrel that can travel 10 to 30 feet depending on the size and dimensions of the stove. So its just the change in temperature that creates the draft.

***** I like the design but I'd be concerned with the 'relatively' cold flue building up creosote which could eventually block the flue or ignite causing a reversal of the flue combustion gases, venting into the house.

question: all of the oxigen needed for the fire is taken from the inside breathable air, so, how to avoid to get killed by that on your living room? open a window? but, if you do that, you are producing heat at the same time you let the cold air in...thanks

@ricardo clemente - homes are not airtight (usually), air gets in via (eg) airbricks, gaps around doors and windows, gaps under the eaves, chimneys, etc. Many regular wood/coal/gas heaters have a similar air supply. But it is not ideal! In cold conditions it draws cold air indoors, so it is usually better to provide a separate exterior air intake vent for a heater. A home we had in the UK had a fireplace that drew air from under the floor, built around 90 years ago. It worked well, but it would eat around a ton of coal over a cold winter. All that heat going up the chimney....
COOL BEANs !
Think about what you just said there... " wood is also finite in supply you got to grow it to burn it". First off, you don't have to grow trees, in fact they did quite well left to grow on their own for millions of years. Secondly, something that grows naturaly is not a finite resource, it is the very pinnacle of sustainability as long as propper forrest management is practiced. Seeing as trees produce oxygen, absorb carbon and cool the environment we should probably keep them around anyhow.
