A Rugged Multi-Fuel, Multi-Use Rocket stove

[@dionneallen5701]

the best one ever . sent from that beautiful garden where man cannot go back . perfect .

[@you166mhz]

I've see most rocket stove design on YT and this is probably the best of them all ..

[@CCMPULM]

Favorite so far. The first multifeed I've seen. I've seen about thirty of these. This one is most appealing. Very well done.

[@Approtechie]

CCMPULM Thanks!

[@putheflamesou]

Happen to build for sale??

[@MikeKincaid79]

Nice design, I like the choice between horizontal feed and hopper feed.

[@muddymuddymuddmann]

THIS IS THE BEST STOVE DESIGN I HAVE SEEN. I AM DROOLING FOR ONE. DEFINITELY THANK YOU FOR SHARING IT. I love the self feeding 45 degree / horizontal hopper. It allows for much heat control, and for adjusting how long you want to cook. and also what kind of cooking you wish to use. It is also compact in size, and it looks like it would heat a small house wonderfully. I really love the total design. My hat is off to you, and your design. MUDDy Amazing build !!!

[@peetsnort]

muddymuddymuddmann try using a cajun rocket pot

[@lanceroark6386]

Woah!!! Muddy! I watched your windmill videos back in 2010. Too cool seeing you in the comments.

[@saeidmomtahan]

One of the best Rocket Stove designs I've seen, if not the best! Been wanting to implement a similar design for a while, but never had the resources, specially the time. Really brilliant execution. Thanks for sharing this. Saeid

[@rockdog2584]

Very well thought out design and appears to be quite stout. I love the large cooking surface and the multiple ways of using the primary cooking location. I can see that this would be ideal for stir-frying in a good sized wok. This looks like something you wouldn't have any trouble selling. Four thumbs up!

[@kc8bdr]

+Andrea Tatham I would buy one.

[@immrnoidall]

that has got to be the coolest looking stove i've ever seen. i would love to have one of those in my house.we have furniture factories in my area that i can and do get an endless supply of free hardwood sticks.they burn way to hot and fast in my regular stove though.great look to of your stove and so clean too.a camper sized version would be awesome too

[@rhythmriderone]

Well thought out, well built. Would like to do this in Fiji (where I live) for the villagers that are suffering from chronic smoke inhalation. The children especially are susceptible and have lived in villages where this was so very apparent.

[@kahakura]

Sir, Thank you for helping folk in our country of New Zealand learn how to become more self-reliant. Plans would be nice.

[@99cachorro]

This is a beautiful design! I think there should be some kind of reward for your ingenuity! I would love to have a stove like that, as im sure, many others would like also.

[@jbossnack]

Awesome design. Very beautiful and functional. You have built a masterpiece

[@firstgeer]

Best rocket stove I've ever seen. Very useful.

[@johnhoward7298]

I can't believe that stove has been around utube for 5 YEARS and I haven't seen it!!!!!! Needless to say.... I WANT ONE TOO , JUST LIKE THE REST OF YOU !!!! I don't suppose it has ever been made commercialy available (complete or just plans) ?!

[@Approtechie]

Sorry, John, no plans and I'm not building them, although I see others building lookalike versions for sale in Japan and other places. I've given the dimensions several times in the comments.

[@d.slater3958]

Wow that is super functional. I will probably use my everlast welder to add rails to my rocket stove like the ones you have.

[@danielsorenson6682]

Yup that's a goody i might as well attempt to make one since the whole of New Zealand is on police an military patrolled COVID-19 #Lockdown cheers thanks for a awesome build

[@Approtechie]

Good luck!

[@dog11222]

That looks like a brilliant base camp stove or for disaster relief. Imagine that set up in New Orleans, soup kitchen style or Africa ..........market it!! well done

[@Zeemike1]

Well designed and well executed.

[@PeacefulCountryLife]

Best home-made design I've seen so far.

[@MacBeckett]

Very nice! Thanks for showing us this! (Sure beats the old oil-drum-with-a-door on it!)

[@CheekyMonkey1776]

Nice build!

[@358Eki]

Nice work! This is not a prototype anymore but fully functional and real thing. Thank you for sharing! I´ll consider something like this when renovating my next summer grill place. Personally I really like the smooth hot plate option for grill and pancake making purposes. Two of these side by side may fulfill every need you have - one with pot holes and one with just a smooth surface. -a pizza oven design might be also possible cause needed action is "fast and hot enough".

[@SierraSando]

I’d pay for one of these in a heartbeat!

[@billandbeaufort]

Excellent!!!! You have covered all the bases.

[@MarkusMalecki]

Excellent design. I love it. Thanks for the video.

[@fyreantz2555]

A fantastic design and setup! Well done, dewd!

[@Approtechie]

This is similar to the Lorena stove from Latin America. It's good for when you need heat in your house overnight in a cold climate, because it has a huge thermal mass. It takes a long time to get hot but when it is you can cook lots of stuff and then it gradually gives off heat for hours after you bank the fire in it. Fiji doesn't sound like the highlands of Guatemala in terms of climate so you might still want to look into other designs. Have you see the Terra Ceta stove? It uses molds also.

[@quercus4730]

Need to add a hot water tank with a spigot on the side. Great stove. Thanks for the video.

[@Jnvd3b]

Finally someone using a pot skirt

[@Approtechie]

Yes, it cuts cooking time by almost half.

[@Jnvd3b]

approtechie and yet no one uses them. Good job

[@MrJoeyBoombotz]

Beautiful result!! I love it!!

[@bronco4life]

Best one i seen on youtube!,,.

[@Approtechie]

The tubing is 4.5" square, there is about 1.25" under the grill.

[@angrygnome4779]

I want one for my kitchen.

[@bangissagaling2076]

Nice job

[@lrh1963]

Nice work! Looks like a great design.

[@rlholt48]

Loved your stove and great video with pics are fantastic. Good job.

[@TheGrayman1234]

I like the angled feed tube. Great idea. Will keep the fuel pushed in for easy feeding, but does that effect the heat coming out the top. Seems like some heat would escape out of the feed tube instead of going out the proper way.

[@grahamsengineering.2532]

That's a beauty. Might have to make one for myself.

[@jesterolog7]

Супер. Именно то, что я и хотел сделать, только нижнюю часть переделаю только под регулировку подсоса воздуха и распала, а боковую подачу оставлю, но чуть длиннее сделаю. Но ваша печь продумана и проста в повторении. Спасибо за видео! Возможно скоро я порадую себя таким агрегатом ))))

[@gulabk65]

Good job

[@xboomer3004]

Best design I have seen, many uses...

[@pauldrowns7270]

Producing heat isn't hard. Producing heat that's useful can be difficult but you've hit every note in the scale...functionality, utility, efficiency, flexibility!

[@hahns53garden]

I am speechless. Thanks for sharing.

[@jameshupalo]

Good job. Simple and perfect in everyway. Love it!

[@RigobertoMartinez6455]

Excelente diseño, por lo visto es eficiente en el consumo de leña. Bonita estufa.

[@pauls466]

THE BEST for sure Well done

[@Approtechie]

Yes, this is why I do this stuff.

[@phylgom]

Thank you for your previous answer. Why did you two entries for the wood, one up and one down ?

[@Approtechie]

phylgom The horizontal hopper is good for lighting the fire and inserting large pieces, also for controlling the primary air to the fire. The slanted hopper works well for automatic feeding of the fire by gravity.

[@Approtechie]

pupnirn I find the horizontal feed port necessary when using it. Even with the pellet burner I use it to force the primary air under the pellet grate. There are probably ways around all of the issues but I still like it and would not want to be without it.

[@MYNICEEV]

MMMMM. I can smell it from here. Fantastic video as always. Many thanks for sharing.

[@edwinzappe9991]

I have bought three of these wonderful stoves, one for my Amma and two for my family in Austria

[@Approtechie]

edwin zappe Interesting, esp. since I don't sell them. Which ones did you buy?

[@mrsillywalk]

Square to round flue is nice! So is the rest !

[@victormanuellopezmaccha5234]

Exelente gracias por compartirlo saludos desde Huanuco - Peru

[@pwleigh]

very good design, love it

[@norwoodzomboy]

Question: would installing metal tabs in the interior of the 'grill box' induce additional vortices in the wood gas, resulting in an even more efficient combustion?

[@apples13able]

A working Work of Art.

[@pandjnixon]

I'm proud of you !

[@andrewjackson3327]

That is a good sized stove man. I want to weld one of those beauties with my everlast welder. Nicely done!

[@TheIndustrialphreak]

I absolutely love this! keep up the good work!

[@emoneyblue]

So well done, congrats...

[@elliottrose2730]

Nice design 🖒good job.

[@SlicksVapes]

Awesome stove, great design.

[@jonbobtrader]

Best design I have seen. Love it.

[@jaysoncrazyman]

I want one, Ever think about mass production?

[@RhisiartGwilym]

Really nice piece or work, Appro. Probably I shall be borrowing quite a few of your innovations for future stoves! :) Can I offer a few suggestions for tweaking up your Mark 2 version, based on my past experience: 1) Make all the fire-tubes in stainless steel. They seem to last for something like ever. Mild steel is fine for everything else, all that isn't directly exposed to very high temperature flue gases and superheated oxygen. 2) Make the insulation >>at least 3 inches thick, all around the entire hot parts of the stove, including the feed-tubes

[@Approtechie]

I've been a Winiarski fan for years and have the publication you link to, read it several times. Stainless steel is not typically available or affordable in most places, but I've found the 3/16-1/4" thick steel to be very satisfactory. I believe the dimensions of the stove are within the general guidelines given. I used it today to boil about 8 qts. of soup in a large pot using direct flame and with the pot skirt, running on pellets. It did just fine, used one hopper load of pellets plus 4 tuna cans more along the way. I light it with a tuna can of pellets soaked with denatured alcohol placed in the hopper first, followed by more pellets until full, and it seems to reach a full burn pretty quickly. I'll post a video on the pellet burner soon.

[@aldobuenahora5589]

Rhisiart Gwilym m,

[@jameslamb4573]

Nice! It's an simple uncluttered design that does what its supposed to. Couldn't really ask for any more than that.

[@soulhunter0]

Very nice, really liked it. i'm inclined to do it myself.

[@jimmyfortrue3741]

Outstanding.

[@randysimper1843]

Thank you for your amazingly quick response! I didn't want to bother you for much more than height, length and width of your cooking surface and the the size of your sq tubing. I assumed it is 4" but you might have used 5". Trying to get a sense of scale. Thank you in advance!

[@Approtechie]

Randy Simper OK, so some dimensions: cooking surface is 13.5" x 22.5" x 2" deep; all square tubing is 4.5" on a side, 3/16"-1/4" thick; 16" from the floor to the bottom of the horizontal feed port; 20.5" from bottom of grate to cooking surface; steel smoke chimney is 3" x 6" x 24" tall; ash box is 4.5" x 4.25" x 8" tall; insulating jacket is 7.5" square and 16.5" long; inclined hopper is set at 53 deg. angle, 18" from bottom of grate to top of it; cooking surface is 34.5" from the floor. There is a metal strip welded to the inside of the vertical tube to support the grate. The grate extends up the side of the vertical tube so secondary air can feed the fire in the upper burn area. Hope this helps. The dimensions were somewhat dictated by what scrap metal I found on the day I went hunting for it, so I doubt the dimensions are optimal, but the stove works great even so.

[@randysimper1843]

***** Thank you so much! Most gracious of you.

[@daveybernard1056]

Very nice.

[@DH-bs1di]

Thanks for the great idea (in a direct, concise video) - but why two feed ports?

[@Approtechie]

The upper feed port works for auto feeding but needs to be kept closed. The lower port can handle long branches and such, not needing to be closed up.

[@CraigArndt]

Nice design!

[@sergeykopylov652]

this is a good stove! I would like one of this kind!

[@TheWindGinProject]

I wonder if you could make a similar design using ceramic material like used on modern outdoor grills. I guess that goes against the rugged objective though. It seems like those in Hati would be interested in using something like this with their coconut briquettes or other types of fuel briquettes or pellets. Nice design!

[@phylgom]

Hello, very nice Rocket stove. The smoke passes across the table? Or there a square tube in the table? How do you clean the ashes? escuse me for my bad english. Thanks a lot.

[@Approtechie]

phylgom Yes, the smoke and heat pass underneath the top steel plate, and there is a steel bar under where the second pot would go in order to direct the heat up close to the plate surface. No ashes accumulate inside the upper section, and the ashes from the combustion chamber fall down in to the ash pot which is easily emptied. Hope this helps.

[@dtap9453]

Awesome design.

[@tijoloorganico4757]

Fabulous!!Regards from SAO PAULO-BRASIL

[@s.a.Bfirestarters]

hey how about the efficiency since the flame didnt hit the pot directly that must be the pot didn't get heat enough from the flame

[@Approtechie]

The hole cover can get up to 900 deg. F and with a pot skirt it cooks very well on the metal surface. Or you can put in the insert and have the flame contact the pot directly and is very efficient when using with a pot skirt.

[@AndyFetisov]

Very fancy I love it.

[@carmenperez3191]

I like your stove

[@Foxboss9]

Very nice, I think my rocket stove, "frankenfurnace" will get converted into this.. What is the plate thickness used for the cook box? Looks like 3/16"... Is it the same all around or did you go thicker on the top plate verses the sides and bottom.. Thanks in advance

[@leonardfrykman3431]

The pocker handle in the hopper vent is how you maintain low heat?

[@Approtechie]

In my early version it was, but now I have air ports on each hopper that are adjustable. Watch my newer video on it running on pellets and you'll see them.

[@bluemoondiadochi]

Respect! great design!

[@kbar4x4]

Thanks for the vid this is in my top 3 rocket stoves.

[@cyborbot547]

classic i would buy one period.

[@russyhoun5255]

that so great idea mate can I see some more please.

[@SouthpawDavey]

Nice build.

[@bellecourt3603]

Nice brother

[@christpuncher98]

great fabrication

[@ktcadd]

what's the purpose of having two burn Chambers? Just for more flame? I would think one is enough??

[@Approtechie]

It gives more flexibility on how it's used and the type of fuel it will accept. One hopper would certainly work.

[@littgaia2939]

I realize this awesome design can cook up a meal quickly, presumably using a relatively limited supply of wood, but does it throw off a lot of heat as a radiant unit, like a wood burning stove to warm a room?

[@Approtechie]

+littgaia It throws off quite a bit of heat, yes. I imagine it could be used for space heating but I've not tried it that way.

[@RDALEHOUSTON]

hello there can this be used in doors for heat and cooking or is it just a grill

[@vukomirjovanovic8934]

bravo majstore.

[@georgehernandez7096]

i like this stove, i like to built this one, i hope you can show me how to build this step by step, it's really safe for the family to cook. I watch some stove in the you tube, but this want is really different its convenient to anyone.

[@blackchisel97]

Work of art. Thanks

[@ronaldfenner6583]

blackchisel9 my7

[@miguelarizmendi5931]

gran idea FELICITACIONES..Y MUCHAS GRACIAS POR COMPARTIR... SEGURAMENTE QUE CONSTRUIRÉ UNA MUY SIMILAR...

[@maxspeedwell1]

Very, very nice. Much like my design but simpler (& less $). What do you think of an under mount broiler between the legs & firebox? Would the efficiency be improved with a vermiculite chamber & a deflector to swirl the fire?

[@Approtechie]

I don't think there's enough heat coming down from the grill channel to do any broiling underneath it. The combustion chamber is insulated with 1.25" of Perlite (an alternative to Vermiculite) all around it. I've contemplated using a swirl device but watching the flame in the box I've decided it's not needed since it already is naturally swirling. This may be due to the box angles and the air channel coming up past the grate that allows secondary combustion and turbulence. And thanks!

[@norwoodzomboy]

Question: is the rectangular 'grill box' interior a suitable shape for complete combustion of the wood gasses? Have you/is it worth experimenting with interior metal tabs to induce vortices

[@thornwarbler]

lovely job......... Thanks for sharing

[@issactate3902]

very well done

[@Gusano357]

very good friend would be amazing that you could see planes contruccion in another video. thank you very much
