A bit of a tip for you with getting small glass panels for the firebox door and (maybe) the riser. The PIR security lights that you can get for domestic installations - garden and surrounds and such. The glass panel off the front of the lamp is heat-proof. Nice and thick too, about 6mm. You don't need an expensive lamp because you only want it for the glass. I've bought cheap versions of those lamps for a little over a tenner. They last a year or so before the sensor goes or they start blowing expensive halogen bulbs and then they end up redundant. I had two or three old ones lying about and had an idea about the glass. Tried a piece in the firebox door (rocket stove like yours) and it's lasted over a year with no ill effects. I've had a word with a couple of electricians and one of them has brought me a couple more of these glass panels. Electricians often fit or replace those security lamps for people. Ask them not to scrap the old ones.

No problem, the gassing effect requires a very hot fire box once you have this your riser will be even hotter, the heat in the riser will now pull air out of the firebox so if you shut down the primary air into the firebox the heat inside will start to to drive gas out of the wood, the lack of air prevents the gas burning. the gas has to go up inside the riser and is ignited by the secondary air The small trickle of primary air prevents a vacuum forming in the firebox. It also stops the wood itselffrom burning away to fast. this stage of the burn produces much more heat, but also because the primary air is not rushing through the system the heat is held for longer inside the exchanger leading to even more heat transfer. Hope that explains it.

I am using lpg gas bottle design which has appeared to work effectively. This year l sent 10 rocket stoves and 2 rocket stove ovens across to them. This Video showing how the secondary burn continues after the primary air has been limited, has opened my thinking to how l can make my stoves burn more efficiently. When l make my next stove, l will be incorporating some of your thinking into it to improve its performance. Keep up the good work and again thank you for putting this video up.

I already was using secondary burn air injection in the burn tube but I wasn’t restricting the primary burn and I was happy with the result I was achieving, but, by restricting the primary air, it was amazing the change I got with the flame intensity. That would of meant my own design was not so efficient. Cheers for your help.... love your other videos as well.. Brian.

For those of us who do not routinely use Celsius, you might want to let people know that 37 Celsius is normal human body temperature (98.6 Fahrenheit), so of course you were sweating madly, you were way overdressed for the temp in your shop. Your normal preferred temp (I think you said it as 20C,) would equate to roughly 70F. This will let Americans have an appreciation of how much that heater can over-perform for your climate.

Been a fan of yours since your original build of this stove. I watch as many rocket videos as I can... and realize that there are 2 types of rockets. Yours is a space heater. This is keeping the most of the heat in the stove with the lowest possible exhaust temp. Then there's the rocket mass heater, where a hot exhaust is desirable to heat the mass. The difference has everything to do with intake air. I followed your lead in restricting intake air with a secondary intake into the riser... I'm getting great stove temps with very low exhaust temps, around 120F. Very pleased, as well as lower fuel consumption, and longer refueling times. Since I have a mass (that needs improvements), I will want to have hotter exhaust for the residual heat... but since my mass isn't absorbing heat properly, I'm going with restricted intake and using it as a space heater. My next stove will have a vortex... I'm wondering how large a secondary could be. Presently, using 3/4 inch (19mil) pipe. I think it could be bigger if it was preheated, like yours.

Hi Wade, That would work but the tubes are simple and work extremely well had there been more room inside i would have fitted more of them, you do need the flue to have at least 50C of heat because a cold flue will fill with condensation and run down into the stove, the heat helps to push it out.

I definitely vote for a small boat/camper stove design. I found your videos while thinking about a small stove for my boat. I currently have a old brass and stainless Taylor 079D gravity drip diesel/kero stove that I like alright but it runs at such a low temp it isn't fully burning and I'm losing a bunch of energy up the flue with lots of unburnt stuff making a mess at times. So an insulated burn pot at minimum to get those temps up. Then I started looking at rocket stoves and how small the amount of wood is used at a time and began to wonder if I couldn't make a multifuel stove that could run on wood, kero, etc.

One of the best features in this design is the internal space left. I have been looking into rocket stoves for some time and watched 100's of hours of youtube vids on different builds. Looking for a unit that can be used for efficient multi-purpose. Having so much room inside the unit would easily allow for a radiator / water coil to be run through the main chamber to incorporate a water heating system for radiators or even hot water supply with a good heat exchanger. The possibilities with this design are limitless, truly a wonderful piece of engineering. :D

Great video. I intend to make a rocket stove and have all the heat extracted from it. The intent is to have one high temperature (80-55C) heat exchanger for hot water (1m3) and a low temperature (30-55C) heat exchanger on the exhaust tube-this will go to a 7m3 low temperature thermal mass-for hydronic radiant floor/wall heating of the house. The intent is to condense the flue gas coming out of the pipe. Where would you put the primary/high temperature heat exchanger coil? I'm thinking right on exhaust tube where it comes out of the body of the stove. Also: I plan a low thermal mass stove well insulated- all the heat needs to go into the storage tanks not the wood shed. Any comments/suggestions much appreciated.

Appreciate all your work over the years for the greater good. Both entertaining and enlightening. Questions please... 1. Could you run the secondary air tube around the chamber at higher level to gain more heat and avoid getting covered? 2. Where do you source your different steel sheet/plate as I am in Leicester and quotes come back pretty high for the different elements..? 3 Do you have an indicative cost for the different components to allow for projected budget? 4. Where would you run a water coil for heating up water if you were to do so? 5. Would / could you do more components in pre-cast mortar, typically the burn chamber? 6. Have you looked at water glass to line or compliment your high temp mortar?

Hi Richard, I could re route the pipe but the stove should be cleaned out every year really which solves it. I went to a local steel supplier and bought it off the shelf some were off cuts that i re cut. cant really remember the total cot somewhere around £150. The coil i would wind around the outside of the riser perfect place. Yes you could cast the firebox no problem with polystyrene burn outs for air paths etc. The refractory mix does not need water glass but i made a mortar mix of it with fireclay and aluminium oxide powder to cement my firebricks in place in the firebox.

Put as many as you can in within reason it will pay off, copper pipes would work great if you fin some way of sealing them to the exchanger, Sec air feed must be at least levelor slightly rising heat inside will draw air from out of the riser and exit the top.

I am in the process of building several stoves at a time, one of them for my 8' x 26' RV camp trailer being a tiny rocket stove. my main concern is it might be too hot to regulate efficiently and considered a log burner style like the one in this video. Its now Christmas eve and Im thinking I cant wait for your tiny build. I very much appreciate your videos and hope to record the process to report back in appreciation of your time and effort put into these videos. Ill be making the burn chamber and riser tube from 1 1/4" fire block. held together with angle iron frame at the corners. I'm looking to eliminate creosote build up and the constant chimney sweeping that accompanies the stove I am currently using, ( an HQ camp stove from Sportsman's Guide) exhausted out a window. If you have any advice as to how to regulate a rocket stove I would be open to any suggestions. Thank you sir for all the time spent making these videos. Because you and other makers out there I now have a collection of about 40 propane tanks of various sizes and having a whole lotta fun. I doubt I would've even given it a second thought if I hadn't seen your videos, I hope to record in some way and show you in return and maybe get some advice, thanks again

Hi there, I suppose really the exchanger size dictates the heat output into the room, that is if you are constantly re-fueling the stove every couple of hours. If you create a very hot firebox you can extend the time between refueling and still have a clean burn. In order to have longer burn times you need a bigger firebox and riser...Actually I will answer your question much better in another video which I will do quite soon, keep your eyes open for it. Cheers

How about a "masterclass" kind of video or series? Give dimensions, details of the refractory mix, casting process? Could most likely just use your existing vids and edit quite a bit together. I would also like, as another commenter mentioned, to see your take on the new breed of riserless stoves.

Great stove, best I've seen so far on KZitem. Wondered if you better use refractory mortar instead of the saw blade? What dimensions are critical to make a rocket stove? Many thanks for sharing.

Thanks i just need some thicker steel over the riser, only critical dimensions are gap over the riser being big enough for gasses to escape too small a flue diameter can choke up the gasses, taller you make the riser better the pull of air.cheers

If you would be so kind as to make a video giving the dimensions of all the parts need to build This one, so I could order the steel pre cut. I would be very greatfull. I can weld and own a welder but have no means of cutting the steel short of a grinder and cut off wheels ,by the time I spend on doing that and consumables I might as well just have it pre cut .Along with the one with the water heater I will go back through your videos to see how the riser was made I must have skipped that one. Just found your channel today and if you make a small one and or a foundry I will be watching as both of are of interest to me. Just a suggestion How about a small version of the water heater -rocket stove for us who like to camp Thank you for sharing your knowledge Merry Christmas to you and family.

Great series of videos - thank you. Small stove would be great - might help answer my questions. Would love to see more explanation of your daily process to maintain and regulate heat and gasification - especially since you say too hot to work. eg once you reach temp and go to secondary air - does it burn super hot for hours or do you need to constantly maintain the box heat/air flow to keep gas moving into riser from coals? Once wood reduces gases does it cool below a point you have to get hot again?

What kind of wood are you burning? White Oak give ourt high BTU compared to other wood, but the is Bois D'arc or hedge apple here in the USA that gives coal a run for its money at over 4500 BTU. I suspect just one "Log" of that in your stove a day will keep you toasty. You need a door on the stove you burn the hedge apple in though, it burns sparky.

Thanks Frank, its ceramic glass (for stoves) the gasket acts as both a sealer and a buffer against the steel, when clamped don it allows the glass an metal to move without cracking the glass.

wow i remember you starting this and your perforated printer paper, its still one of the best on youtube. i have a lovely efficient diesel heater that came off an old ambulance i had years ago, not everyone's as lucky, and i'm a warm weather camper so have no space to gloat, but do you think that design would scale down to half size for people who do have to live in a van in the cold?? obviously building half size is mechanically simple but fires have airflow and airflow is fluid dynamics which is rocket science, the air wont be half as thick etc

Hi mate, I think it will actually i spent literally weeks to get my pizza oven burning totally clean and HOT on a 15 inch high riser with an over sized fire box, I did build a mini gasser out of it which ran very efficiently but slowed down the burn, it didnt have the punching power of the riser burning fully open though, The gasser would be great for heating a space though.

That stove is impressive, I'm here in Scotland looking to build a rocket stove for the garage workshop. I think this stove is too big both physically and heat output. You mentioned a smaller stove, I'm interested. Do you have any experience in 'scaling' down physical sizes and the performance of the stove? Thanks for making the video's.

Excellent series of videos ...You say that 10mm is too thick for the 'bell' which is a shame as I've just inherited a 420mm diam x 10mm thick tube and a 10mm top to weld on. Would this not work even if I channelled the heat through a 'mass ' bench or does it not cool enough above the heat riser to draw?
@LozHarrop
6 жыл бұрын
Hi and thanks, yes it will still work as a stove just not as efficient as it could be you will transfer more heat to the flue though which you can extract with your mass, probably the same outcome as a thinner exchanger in the end.

What do you use this for, just heating? Could this (or something like it) be used as a kiln to fire clay? I was wondering if you might do some sort of black smith work with it. As another question. I frequently see rocket mass heaters or mass hot water heaters where you heat up some thermal mass - a cob couch or bed off the vent or a hot water tank with tubing conducting your water that you're heating. Not anything I'm ready to deal with yet, but, maybe start with just the stove eventually. I like the idea of independence and efficiency. I'd like to have water, heating, hot water - how nice would it be to take hot a bath in a tub, maybe in a copse of bamboo. Interesting stuff. You'll survive the collapse comfortably, if/when it comes.

Hello from Greece! I've viewed all your videos about the rocket stove. You worth some kind of prize! Bravo! I have a question though. Do you think it's possible to combine your rocket stove with a water coil inside to use it for heating other rooms in a house? Will the coil last? Thank you for sharing all these informations with us!

Yes a copper coil will be fine inside the exchanger or around the outside of the riser

I'm wondering: would it be advisable to build a bespoke flue that has your secondary air flow running through it as a heat exchanger so you both preheat the incoming air and remove some of the heat from the flue?
