- Gravity fed pellet rocket stove meets 300 ltr water tank.
Made this about a year ago. Its had about 100 bags of pellets through it and still good,
Thought id do this vid as i want to make some changes, in a few months and it might be of interest to see how it evolves.
I like projects that evolve. I've got a powerarc welder and plenty of metal projects that are still evolving and being tweaked.
Technical bachelor! A joy to watch his creations!
Very nice! I love the simplicity of rocket stoves and how efficient they are, I would love to build one for myself to heat a hot tub and I think your design might work very well. Thanks for the inspiration!
Thank you Mike, check out my other stove it glows in the dark its a longer version of this one but with a extra feed chute for solid wood, it might be better for a hot tub, thanks again
Very cool set up! Idk what all the hate is about? Only thing I would change is that I might try to bring the air intake from outside (or my basement). To keep the ambient air inside the house from being sucked out (whether winter or summer), but also, cooler air gives a more efficient burn.
That is a very slick installation! Something like that would be awsome to heat my garage. It would be quite easy to install a screwfeader that feeds the stove when the level of pellets reaches a certain level. For exampel, a spring loaded mettallic lip in the feeding tube that spring up and close a circuit when the pellet level goes below it..
Wooov its a big deal. Well done. Amaizing mankind thinking... Greetings from Turkey...
You Sir are a awesome thinker and welder and power lifter, gotta be to move this beast/beauty around 👌
LOL your right about the weight of it. thats why i bought a pallet truck,
i fixed a hoist to it, I ought to do a vid on it. sorry i took so long getting back, and thanks for the comment.
@@denman8567 and he likes scalding hot showers!!!!
That's awesome. I should make one with my everlast welder this winter,.
It's got a lot of potential
Cheers mate
You might want to add a burn basket in the chamber to prevent gasses from backing up into the pellet hopper. This will prevent cases cooling in the hopper and creating pitch which could back flash..
Interesante instalación, se aprovecha el calor para sistema de calefacción con agua. Excelente. Lo otro bueno, la música, y por si alguien no sabe el nombre es La cabalgata de las Valquirias de la obra El anillo de los Nibelungos de Richard Wagner. Aplausos desde Chile.
that's so cool! i have an oil barrel J rocket stove and am planing on running some tubes inside of it to warm my water up. awesome project maximising the space available. awaiting for any upgrades ;D
Thank you, Let me know if you do a vid cheers
DAAAAAAMMMMMMNNNNNNN!!!!! I think you built the Terminator...
You have my attention, quite an elaborate setup, if you make changes to set up can you please give more specs on performance and fuel usage. Thanks
Hi thanks for the comment, and next time i get time i will give the specs, but i can tell you it uses 3kg in 2 hours and thats without any fine tuning I think there is room for improvement, cheers
Un grand Bravo de France !!!!
merci Lionel, If your near grenoble you could pop in and tell my sister to take a look,
How long does it take to heat the 300hundred liters of water and how much pellets does it take to heat all the 300 hundred liters of watet? THANKS
Kept expecting to see "In a galaxy, far, far away" scrolling up the screen.
wrong movie

Den, nice video. However I was under the impression that a rocket stove is supposed to use scrap wood so it's basically free. You're using pellets. So, why pellets and not just scrap woods? You're spending money on pellets.
But a great way to heat the water for home heating instead of oil
Hi Bee Bob,, I wanted to see if i could burn the pellets without using a basket after watching so many vids with baskets..
Yes your right about scrap wood,, thats why thats all i use now.
Although i do use house coal now and again that works well also, Ive tried the lot stale bread, chees, oil. lard.
once its going it seems to incinerate everything with very little ash at the end of it and even that gets tipped back in the next time .
thanks for the comment and view
" I was under the impression that a rocket stove is supposed to use scrap wood so it's basically free."
They were initially designed for the 3rd world where people were cooking indoors with an open fire, due to necessity, but developing high rates of emphysema, among other lung ailments, and their primary purpose was to provide a clean way to do this.
The fuel is unimportant, a secondary consideration, the J tube was developed to burn everything, including the exhaust gases most fires produce, smoke, etc, so that the only exhaust is CO².
I want both you Bee Bob, and Den Man to please check out a fellow UA-camr™, by the name of ppotty1.
First to show you it can be used to burn big fuel, but to also get Den to start thinking on a batch box feeding his J tube.
Cheers and Shalom.
Nice project you got going there. I'm looking to weld up some kind of burner with my everlast. I haven't yet decided on the fuel source though.
Thanks for the compliment. i was the same as yourself infact mine started out as a garden ornament (chimenera) lol
and thanks for the view
The music was pretty corny but the stove looks nice i like the idea. You don't worry about the PVC melting on the inlet? Also how is your water pipe connected to it? Is it wrapped around inside the burn chamber somehow? How often do you have to keep adding pellets? Maybe a bigger feed storage would be better.
awesome 6 mins of shaking camera of the outside of your heater.
Does the pvc air tube suck basement air or crawlspace air? Cool invention. Are the side tanks fill tubes or one side cut off to contact main stove pipe?
Okay, you wanted to know why I gave you a thumbs down when I almost always give people a thumbs up just because they took the time to post something so here goes. I have absolutely no idea after watching this how exactly this thing works. Your title tells me it's a gravity fed rocket stove that burns pellets to heat a large water (assuming their is water in it) tank. So, how much fuel does it use? Why are you putting coal in it? Is it necessary? Why not mix the coal with the pellets? How long does it burn on one load of pellets? How is it constructed meaning why have a shelf half way in the middle of the inlet pipe? Why have a baffle that you remove and put coal in below the shelf with the burning pellets?
To be blunt, I didn't learn a dang thing and I'm not terribly impressed with it compared to others that I've seen here on youtube.
You asked for it so I gave it. I mean absolutely no disrespect to you sir because you have done something that I haven't but, I'd like to know exactly what you did. What are the changes you plan (according to your written introduction?
Maybe you should watch one of the other vids i have done, where i go into some more detail. Or read some of the comments where i have answered most if not all of your questions
Thanks for your feedback though
I don't think even Heath Robinson would have come up with something so flawed and dangerous. Hope you are still around to read this comment
Awesome, love it!! Post more!
Hey! Would you share your expirience with it and the plans for building a system like that? Thanks!
That flexible pipe on your chimney its an porblem in time apear holes and u can burn your house from that an friend of mine hawe that flexible pipe for chimney 10 years and this year his howse burned down from that flexible pipe
Great concept, glad to see it working so well.....maybe next video you get a tripod and set the camera on it, I along with others find it hard to watch.
Thanks David, its my first vid and my first upload so still learning.
Also explain what it is,how it works etc.
Can you post a video about how you built this?
I'm impressed. Your workmanship and end results speak louder than all the ummms and errrs and bullshit a lot if people add. It clealy works very efficiently. How do you make the pellets? Or do you buy them?
I'm interested in building a solution that burns workshop wood waste in a variety of sizes. Gravity feeding seems to rely rather heavily on a degree of liquidity to the flow of fuel.
I think the answer might be something to make pellets from waste wood. Instead of trying to make something that will burn irregular bits of lumber make a system to chip and press wood waste into pellets. The thing with rocket stoves is they burn wide open and large irregular lumber will require a large feed tube that creates a huge fire or you will need to spit it down to fit a more reasonable sized feed tube so why not just process it into pellets with a chipper and press system and make pellets?
Yes good point about the tarring up, but i dont see how a basket would help? if you can explaine why a basket would help please share it with me. In the mean time i drilled some small holes in the base of the pellet hopper to stop the gasses building up in the hopper (not in the vid), witch seems to work. Thank you
nice work!
Thank you

Hi Den,,
Since you have the product installed, and it is only 6.08 minutes long. For greater appreciation of your video and skill please reshoot and post it. ( Other wise it is looking like a a great skill with poor presentation !)
Thanks Stanley, you sumed it up perfectly, I didnt expect so much interest, I was just glad i managed it at all lol

Great work dude but It would be great if you actually explained what’s going on but I’m totally in the dark how it works.
Have you got any means of controlling the return temperature? A thermostatic valve set to maintain a return temp of 60 degrees c will dramatically reduce tarring up of the flue and stove.
Nice! The vid is a bit confusing, but like you said below, first vid. I suffer the same humiliation...
I built a basic J rocket, 55 gallon drum, 35 feet of flue with a ton of mass... it rips but, like you, I need to tend it regularly, every half hour.
My stove taught me a lot about rockets and I'm planning on the 2.0 model. I am going to put coils of tubing in it, a circulation pump, reservoir tank, radiant heat... and of course... a larger firebox (I want to burn cordwood instead of sticks).
My present stove can burn pellets. I made a basket out of stainless steel, and it runs super hot... but presently, pellets are expensive, wood is free (plus labor).
Please make another video, explaining how yours works... I was drawn to this vid by the plumbing.... again, great job!
Thank you Thomas Everyone should build a rocket stove. Ive learnt so much from this one the next wont look anything like the mk1
And like you i dont use so many pellets because they got expensive. and i find a good pallet broken up does just as good. Thankyou for the comment
Den Man learnt
May suggest that the exhaust be not at the top. The stove would be more efficient if the outlet were attached at the side of the stove at the top of the firebox.
Yes, I was thinking of cutting off the Top 400mm. and making a heat exchanger, There are some good ones on youtube. Thanks
Dali je u vreme snimanja ovog priloga bio zemljotres pa se slika ovoliko trese ,ja ne videh tu gorionik na pelete . ja sam napravio kotao za centralno grejanje na principu raketne peći koji kod loženja drvima ima izuzetnu efikasnost . kod liženja peletom nema neku efikasnost pa bi trebalo uraditi neki automatizovani gorionik .
Ok ok felicita
Cool build, bit of a fire hazard perhaps?
It s coal pellets may?
Need a handle on a 1/3 moon shaped piece of steel for pushing that coal
Hi Den I am wondering think it is big enough that a person could put the hot water threw a heat exchange-r and heat a house with it? I take it that you have a blow off valve. Nice video nice set up!
Hi Marc Thanks for the comment. Im using a open vented system like they did in the 60s so it dosent need a blow of valve. Im sure that if you used a diverter valve so it did one or the other it would work.. but i would have to look into it a bit more using a heat exchanger method.. did you check the vid with the radiator heat exchanger i made?
Thanks for the view Mark
Çok güzel.
ДЕН. РАССКАЖИ ЧЕМ ЗАКОНЧИЛСЯ ЕКСПЕРИМЕНТ .
looks like a hundred year old house, I got an idea let's install a pressure cooker bomb in the basement
Shawn/IO if the house is that age it's probably an open vented central heating system, won't explode but may boil and rumble a bit.
Impressive work.
I'm just about to build a sauna heater/bath water heater rocket with a 100mm diameter system and I'm wondering how you organised the water heating section..
How long of a burn does it take you to adequately heat your water?
Do you have problems with water vaporizing and expanding?
Thanks for the video!
Hi sorry for the delay getting back to you, Im using a open vented system so there is never any preasure in the system it just vents to atmosphere out side the house, but ive never witnesed anything come out, it tho it vents up about 3meters of 22mm pipe, Heating the tank depends on how big a tank you go for and i find 130f to 140f a good temperature to keep the tank at, also my tank is 300ltr twin coil and just letting the water convect through the top coil it takes about a hour to get hot, hope this helps good luck with your project and if i can help any more just ask Thankyou for the comment.
Piss pour photography!! Couldn't even see what you did that was worth posting!!
Looks like all you're going to do is mess with it constantly feeding it emptying it out I guess it's cool looking I guess
This makes me realize I'm overthinking everything.
Thanks for looking. overthinking ?? How so Big Dan?
I honestly can't remember. I've been on the hunt for a while now for ideas. I'm trying to learn from others mistakes, and the more I want to do something with the fireplaces in my house the more I want to just build a big thermal mass water boiler in the garage and just heat with that in the winter and run solar in the summer.
I'm thinking of a rocket stove on a much larger scale.. Or I'm going to have to figure out how other gasification systems work.
I was pretty much the same, untill i realised how good the draw was on my chimney, its about 9 meters tall or about 30 feet tall and it was sat there doing nothing!! I would only get a 4 meter chimney on the garage
and it would of cost me.
Ive seen alot of vids where people seem to want to keep the chimney cool. idont think they realise that the hotter the chimney the better the draw, thats why a lot of rockets smoke a bit when you light them..
If i were to make another it would be the same size but with a much much better water jacket. and a much bigger feed tube.
ive got a copy of the (wood gasifier builders bible) Next project lol
good look Dan
good job!
is your stove still running today? any rust due to extrem heat in the combustion chamber?
Definately bachelor pad
It 's not a rocket stove .
Temperatue of the exauste ?
If its not a rocket stove what is it?
Pretty crude
that is not a rocket stove. the main catch of a rocket stove is to not take any energy off the the flames, that is why the riser is insulated in refractory material in a rocket stove.
If he insulated the riser, the metal riser would soon fail.
metal is doomed in a rocket stove above 4" system syce
So what's this guy squatting in this house? I swear I would go and steal my neighbor's hot water heater before I went through even half of this
Its a back up. when the electric goes of for a week in mid winter,, guess What ill still be having a hot bath
get air fan from PC to increase heat)
Thanks for the comment. I honestly dont think it would do anything if you watch onof the other vids you can hear how much natural draft there is,
If anything you may notice how i have to block of the air to keep control of the flame, that being said i want to have a play about with it ths summer on the back yard and a pc fan would be perfect then. once again thank you
Fans are all well and good but what happens when the lights go out.... K.I.S.S.... Keep it Simple...Keep it Stupid...
Great billed I hope you have insurance on your house
Thanks for the comment, I dont think the insurance people would know what to make of it lol
Bonsoir monsieur que Dieu vous aides amène
Not certified so not insured
tar in the hopper not good .. mens backdraft courses fire in the house some day you shout work on it before it too late
How long does it burn on a full load of pellets thanks
Hi stotas, It only runs for about 25 mins on 1 full chute wich is about 770 grams. I could put a hopper on and increase this but seeing as im not completely satisfied that the glass is good enough yet. i dont mind keeping a eye on it every ten muinets or so.
Hope this helps and thanks for looking
How fast does it burn the tube of pellets? I am experimenting with using a rocket stove to heat 1,000 gallons of water that I store underground to use as a "thermal battery" for my radiant heat floor. You can check it out here: ua-cam.com/video/CqwwY_tRQAk/v-deo.html
ye loud music sara maja lharab kar diya
Have you tried it on anthracite coal?
Hi Paul No i havent yet. But normal house coal works good.
thanks for the comment annd view.
may i add in a personal statement a down vote without a comment = rocket stove envy so its a back handed up vote THANKS LOL
Den Man i think you get the point do more with less,commercial manufacturing doesn't get it so smart diy,has to.
I'm guessing your a single dude...:)
Its hard to find a pretty rocket stove 😅
COOL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Just move to a country where is warm all year:))
Location, soviet union?
UK England !
WTH? Whats going on? Stop shaking!
what have you done to prevent the pellets catching fire and burning in the feed tube ?
Absolutely nothing Carol the draught (pull) from a 9 MTR tall chimney is so strong the fire can only go in one direction ,,, up the chimney.
although there is a lid on the pellet chute. hope this is of use, and thank you
🤔
Please reshoot with instructions!!!!!!!!
What's the F with your right hand?!
Привет я хотел узнат ваша печка работает с углем да
music super!!!)))))))))) Soviet music?))))))))))
Cheers, its called the flight of the valkries, and Wagner was a German,
The Ride of the Valkyries, by Richard Wagner. Great classical music.
Hilarious
