In this video I show the details of a rocket stove heater I made from two gas bottles and other recuperated materials. My challenge was to spend as little money as possible and to make an aesthetic and efficient heating system that could be put in a wood cabin.
- I spent $20 to make this stove (a piece of inox piping for the heat riser, some welding sticks, grinding disks and some paint). This
does not include the driving around finding bits and pieces nor the chimney exhaust pipe.
- This heater gives off amazing heat, its potential is by far underused.
- It would be the perfect system to use as a mass heater.
- When the burn chamber is hot, there is no smoke at the outside chimney outlet. Also creates very little ash.
- Metering the wood is important, that is cutting wood to a certain thickness and length.
- When alight the stove does require attention from time to time.
- Like I say in this video the outside air intake is a must, as it avoids cold air currents in the room or if the room is well sealed it avoids
depleting the room of oxygen !
- Like all home made rocket stoves, each stove has its own personality ! So it takes some trial and error to get to know the stove and
how it works best.

Many thanks. Most informative rocket heater video I've seen to date. Used your ideas for external air intake and gravity feed for fuel. Added a lid to seal feed chamber and a sliding valve to regulate air intake. I soak little blocks (approximitly 40x40x16mm) of pinboard in kerosine and use them for firelighters.

very clever :). Time to fiddle around, collect odd bits of scrap, spend an enormous amount of time.. and warm my studio next winter. Thanks for the clear explanation.. [( I might try a larger fuel receptacle - although of course the idea is to use as little wood as possible..but perhaps look at increasing the burn time ), perhaps a bit of flow control for air intake to mess about with burn time, and yes an external air intake also damped for flow control]. See what I can scab from the local tip eh

when starting put in a clump of wood shavings and twigs first then the paper. As the paper burns it'll have to go through the twigs etc lighting first time. So people put paper in first then twigs but the paper is burning and the twigs will compress the paper down and in some cases put the fire out. Very nice design. Perhaps an outside shed with rocket stove built into it and pipes to transfer the heat only to the inside of the cabin I heat my workshop this way no internal fire just masses of heat coming in through pipes.

@putheflamesou

I built one with a barrel. Filled a file cabinet drawer with wood stove liner brick6x6.5) The riser a 7"x 30" insulated ss chimney like you get at Menards(don't know why 7" and not 6") but I got it at a auction. It worked well for a month. Had some wood chips and loaded them on wood pieces angled in upright feed chamber once it was warm even added used veg oil. Some chips were moist and burnt excellent. Then I cleaned up outside around the pile and some had ice on them. I shredded my riser liner with the moisture that day I believe. Pretty sure it was due to moisture in the chips. Used 5gal of chips a day along with split wood. So wanted to ask how long you have been using your riser and what it is made from...and warn against using moisture if it is metal. I was thinking the moisture was like a steam cleaner- bad idea I think, or was the ss riser going to disinitigrate anyway? The stove quit working that very hour. Did not rebuid yet thinking about refractory cement this time.

@haroldwestrich3312
@haroldwestrich3312 6 лет назад
NICE stove , I like that "self feeding" part and Have built a similar stove with 5"x9" self feeding tube about 48" tall, it had a lid and this makes it easier to connect your outside air someplace very low like maybe a flexible aluminum connected to the "Plug" you use on the clean out. Having an extra low intake point allows the wood falling into the fire to burn at a slower more steady rate. The next step (Which I did and worked great) is to somehow preheat your intake air. In your case you could wrap the aluminum tube around the main tank. My stove had a full metal jacket with about two inches between burn chamber and outer jacket, in this space is where the intake air collected it's heat causing the fire to burn at a higher temperature. My biggest problem was that Soot would build up on the sides and glue the wood to the side preventing it from dropping into the fire. Another problem was extremely hot fires that would burn any grate completely out in 8 hours or less, I tried 1/4" stainless steel solid rod and after about 8hrs the center four inch diameter was gone with ends tapered down to points. Good luck with your next GENERATION! ! ! ! Harold
@gaetanproductions
@gaetanproductions 6 лет назад
Thanks for your feedback Harold. Lots of good ideas. Re heating the air intake I am not so sure it is a good idea, as you have seen it gets too hot... it would be a good idea if you wanted to meld metal, like a rocket stove furnace. For a rocket stove heater the right mix of temperature produced and materials used is necessary. A burn chamber in brick could be a solution for this.

Thanks for posting/sharing, you have to deal with ash eventually, if you could incorporate a small hole expanded steel grate bottom that would allow ash to fall into a removable drawer, you might consider that, please not trying to tell you what to do, just a thought. If my Dad was alive he would be ninety years old, when i was a kid he used to tell me about the old coal stoves, that had that ash shaker idea
@gaetanproductions
@gaetanproductions 5 лет назад
Hi Len, thanks for your ideas, they are more than welcome ! The great thing with these stoves is that there is very little ash generated as there is near total combustion when the system is hot an running. Though at some point ash does need to be removed. The ash shaker idea could be good. Thanks for sharing your views.

@gregp4557
@gregp4557 7 лет назад
Thank for your response. it looks like you wrapped the top half of the riser tube with copper. Or is that just discolored stove pipe? Also, regarding the height of the riser tune. Is there an ideal ratio of the area of the intake or size of the burn chamber to the height of the riser? Does it affect airflow or heat transfer? I have read that the intake cross section should match the riser and exhaust cross section for good flow, but then people often restrict the intake for a slow burn, so I'm not sure how important that it. You mentioned wanting to make the feed tube larger. is that just allow more wood easily or to affect the airflow? Thanks
@gaetanproductions
@gaetanproductions 7 лет назад
Yes I there is an ideal ratio involving burn chamber size, riser diameter and height, getting close to the perfect ratio will of course effect over the overall functioning and efficiency of the heater. I made my heater with more or less what I had and with trial and error, a lot of common sense involved, like proportions for example not having an over large burn chamber or a small diameter riser. Keeping the same section of piping is important. Re the feed tube, I only had rectangular piping the square one would of been perhaps more practical as a wood feed. Restricting the air intake is a good idea for burn control, thought I have not experimented with this as yet.

Nice heater. Wondering if you could capture some heat into a thermal mass. You have efficient combustion without efficient heat storage.
@gaetanproductions
@gaetanproductions 8 лет назад
+Harold Mack You are totally right, a thermal mass attached to the exhaust would make it perfect and it could be used to heat a far bigger space. I wrote in the description that its potential is under used. I designed this stove to heat a small wood cabin. The reason I did not experiment with thermal mass is one for limited space and two the wood flooring would not support the weight needed for an effective thermal mass.
@EVZebra
@EVZebra 8 лет назад
Its a nice build I like it. My version of this is to have just a normal little fire place with a flat top so I can pot a pot on it I am greedy and I want all the radiant heat, so i want to see the naked flames. A polished piece of stainless steel at the back to refelct even more of the heat out the opening would be good too. The exhaust runs up to just below the ceiling and then goes right around the outer edges of the room, all 4 walls, and then out the chimney. I would use quite a heavy gauge pipe for this. The reason for the height up to the ceiling is only to prevent people burning themselves on it, ideally it would go from the fire right around the room at about a 20 deg angle to help the rising hot air create a daft, but some one is going to get burnt if the pipe is too low and a tall large diameter12" or 300mm chimney will sort that out any way. The heavy gauge pipe acts as a thermal capacitor and the heat from the fire does not escape out the chimney the pipe is so long that by the time smoke comes out the chimney its only slightly warm Its like a cars radiator it has lots of surface area. Then you put in a very small amount of wood which burns off in say 20 - 60 min and the thick walled steel pipes take on all the heat and this keeps the room warm for another 4-8 hours. Burning wood is carbon neutral, only fossil fuels cause more carbon to be released when burnt than what the wood took on to grow into a tree. So you can burn more wood if you want to but I like to make the fire once at say 8pm and its out before bed time to reduce the fire hazard, and the amount of money I spend on wood, the thermal capacitor then keeps the place nice and toasty till morning - in theory any way I haven't built one yet its just an idea.

How do you clean the creosote that will eventually build up inside the walls of the outer chamber? You need to create an ash pit to extend further inside the vertical rocket pipe to assist ash build up that will inevitably occur after many hours of use
@gaetanproductions
@gaetanproductions 9 лет назад
Hi Joseph, good question. Actually the two gas cylinders are not welded in the middle so they come apart for eventual maintenance. Good point re the ash build up. When I use it, I never use it for more than a 3 to 4 hours, the small amount of ash that remains I clean tout before every burn.

Would you use other material such as brick? Thank you.

Thanks for your comment ! I don't use this heater all the time, so it's life will be long ! I have had the problem you mentioned with the rocket stove I often cook with. What I did was plaster the hole with clay. It fixed the problem. For sure natural heat resistant and local materials are the go. There is a solution to do a mix, that is make the structure in metal and surround the burn chamber and heart riser with a layer of cob. So if the metal does piece, there is a back up.

Thank you. My answer to your question would be yes. Though I have never tried this. I would say if the exhaust pipe is too long there may be issues of hot air flow and draw when starting the stove. I would say that if the draw gets going and once the stove starts producing heat and hot exhaust it shout not be a problem. The only way to find out it to try it out with your stove. Cheers

Fantastic! Did you cut the bottom tank's top off? What gauge of steel for bottom and fire box? Job well done.
@gaetanproductions

Thanks Norman. Yes the bottom tank's top was cut off. 2mm steel

When I made it I was in full creative mode, grinding, welding, and experimenting... in the cold and I had no construction plan. That's probably why there is not a "making of"... Promise that next one there will be a making of !

very hot is a good answer. I built a stove using 1/4" x 4.5 x 4.5 metal tube for the burn/feed tube and the chimney and a 30 gallon barrel 29" tall centered over the chimney with the barrel top 2" taller than the 27" chimney. The chimney is insulated with a piece of triple wall stove pipe. The stove has reached 330 degrees F (measured using a wood stove thermometer) but I was hoping for much more heat. My stove looks similar to yours. I wonder if I did something incorrectly.

+roy hoco Your heat is going up the chimney rather than being transferred into/through the metal. Some Aluminum or Copper baffles would help (both internal and external and the top surface on which you might want to cook should definitely be a good heat conductor - I'd go with a good sized sheet of copper clad aluminum. Air movement across the stove will also draw off heat and thus improve efficiency and a bit of creative thinking might get the exhaust gasses to drive the fan (but be mindful of exhaust pressure).

+Paul Smith thanks for your input, I use various items to capture the heat and transfer it into my shop. I use discarded automobile brake hubs which are heavy and hold a good amount of heat for later release, I lay them on top of the stove and stack them two high. An old shoe cobblers stand that is a piece heavy metal, cast iron pots filled with water, short pieces of railroad track they hold a lot of heat and release it slowly and anything else I can find that is thick metal. My shop is large (heating 2,200 sq ft) and the new rocket stove will make 3 wood heaters for when the cold of winter arrives. I can burn one or a combination of the three depending on the weather. The only thing I can think is I was test firing the new rocket stove outdoors on a slightly windy day when the temp reached 330 so that might be a factor. I will fire it indoors this winter and see what happens.

+roy hoco Thanks for your input - Yes I agree with you and Paul Smith re increasing the heat transfer capacity to be able to use more of the produced heat. This being said my rocket stove heater works more than well for the space I have and I wanted it to look good. So adapting the rocket stove for your needs is important. How I could increase the capacity of this stove would be to instead of having a medium sized gas bottle on the top, it would be to put a big one, and as well increase the height of the internal insulated heat riser. Re your question about your stove, there may be some proportions wrong... The way I found that out was by experimenting. there could be too much air intake, or inner spaces too big. You will know when it is right when there is no smoke coming out of the chimney and a good heat produced. I would aim for that before welding bits of metal onto the heat exchanger. During the building stage it is of course good to do test firing outside, however to really see what is happening you need to do an inside test fire with all the conditions (like chimney length for example) Hope this helps.

+roy hoco Your brake hubs are doing what I suggested and are a great idea for the top surface but not as efficiently as would internal and external copper or aluminum fins. The idea is to use less fuel for the same amount of radiated/convected heat. Removing the heat from the canister surface would improve thermal transfer. My suggestion to use waste heat to turn a fan was just a random thought to stimulate further experimentation as is my suggestion to use waste heat from the chimney to preheat the air going to the combustion chamber. Hopefully I've sparked a helpful idea or two.

Hi, One of the best presentations of rocket stove. Congratulation !on this pioneering technique ! which I believe inspired many to build such Rocket stoves. I have already tried with a normal 3 gallon or approximately 12 liters bucket with a ceramic pot inside feed from the top and exhaust from the top similar to your one. Guess what !It worked ! So I am going further to include wet back we call it in NewZealand to heat water from the fire source. Did you know if vertical feed existed before you built this one? (My teaching colleague mentioned, that vertical feed existed or was in place but may not be your designed style. Thanks for the inspiration. One small request if possible. A thermometer will only cost about less than $15.00 if you could possibly get the reading would inspire the reader /s more. Also you mentioned there is insulation for the inner tube where fire is raising.and hitting the top. From the picture I could only see metal was there another casing of metal to hold the vermiculite?
@gaetanproductions
@gaetanproductions 7 лет назад
Hi Stanley, thanks for your generous complements. Yes the vertical feed has existed for a long time. Re the thermometer sure it would be interesting, lets just say it gets very hot ! The insulation on the inner heat riser is vermeculite, there is the inner pipe then the vermiculite then the outer pipe. Make a video of what you have done, sounds interesting, if you do please send me the link.

I am impressed with your design. Do you think perlite is any better than vermiculite
@gaetanproductions
@gaetanproductions 8 лет назад
+David Epperson Thank you David, I have no practical experience to you answer your question. I have read that they are more or less the same in insulation performances. There are a few articles on the internet. I used what I could find available cheaply and that turned out to be vermiculite.

Id always wondered why no one had made these self feading, eg. use gravity to make the wood drop into the burning point. Id say you could ad and air inlet to your design without to much hassle. good stuff

Lovely design! Could you perhaps tell me why the burn box is insulated? To my mind that wouldn't affect the draw and radiated heat is a bonus, surely?
@gaetanproductions
@gaetanproductions 7 лет назад
Thank you ! The hotter the burn chamber the better the combustion. So insulating this part helps contribute to a cleaner more complete burn of the wood gases.
@DrMemory667

Very nice design. I'd be curious as to the temperature of the exhaust gasses, how much heat is going into the room and how much up the flue.
@stephenmillett8174
@stephenmillett8174 6 лет назад
Reddy Kilowatt i can put my hand over the flue outlet on mine..... the heat gets aborbed into the thermal mass of the tank, the gasses go out the flue
@MusherDeeds

great build! I am planning on making one this summer. Is the vermiculite just laying inside the exhaust chamber? Also, whats the output like? Does it heat the room quickly? Does it get to hot?
@gaetanproductions
@gaetanproductions 9 лет назад
Thanks. Yes the vermiculite is just laying there at the bottom of the heat exchanger. "Does it heat the room quicly?" That will depend on the outside air temperature. To heat my 16m2 it takes about 15 to 20 minutes. "Does it get to hot?" Once it got too hot but it wasn't so cold outside. So that again will depend on the outside air temp. As there is no air intake control there is no way of controlling the output heat. After about 15 minutes when everything is nice and warm it really rockets away.

nice and simple how did you connect the 2 halves and still be able to take them apart
@gaetanproductions
@gaetanproductions 8 лет назад
+thegreatfixer I spot welded and sealed (with high temperature paste) a ring of flat metal to the upper gas bottle that over laps it, so it fits over the bottom bottle. Creating a "joint", I did not seal this and have had no smoke come out from here.

great heater,could you please elaborate on how you used/fitted insulation
@gaetanproductions
@gaetanproductions 8 лет назад
+Phil Williams Thanks. Have a look at the drawing at the end of the video. Outside the gas bottles, around the burn chamber I created a metal box and filled it with insulation. The inner chimney is doubled, simply filled at the bottom I used a high temperature past to close any holes, at the top I cut many cuts into the top of it and bent it over to the inner square pipe. For the insulation in the bottom of the lower gas bottle, I just filled it to the lower level of the exhaust outlet pipe.

+gaetanproductions did you use loose vermiculite ,i have been considering mixing vermiculite with cement
@gaetanproductions
@gaetanproductions 8 лет назад
+Phil Williams I used loose vermiculite. I wouldn't mix it with cement, the cement will fill all the air spaces taking away its insulative properties thus making it less effective
