To improve this stove you can add a "Sand Battery" to it which will allow it to continue to put out heat even after the fire goes out. Take a 6 to 8 inch pipe, cap 1 end, split it lengthwise down the middle, weld each half to the outside of the barrel and fill with sand. The fire will heat the sand and then the sand will release the heat.
I've made the exact same setup, but with a fully insulated burn chamber and riser out of ceramic fiber board, to make the fire even hotter without damaging the steel structure. My highest temperature ever recorded temperature measured on the top of the gas cylinder was 800 degree Celsius and regularly temperatures above 700, this is measured about 1.2 meter from where the actual burn happens, it melts steal there. Every few months I need to replace the 2mm walled stainless pipe for my secondary burn because the heat just eats it away, very efficient stove, can run 12 hours one box of wood (10-12kg)
Thanks for watching Great question there is a formula for the height of the feed tube in relation to the horizontal and vertical pipe there are several sites on the web to show the math But I’m pretty sure if the feed pipe is too tall it will not work properly the air flow friction rate will increase as will air blockage by the larger amount of fuel (wood)
Yes it will but not as efficiently there is a calculation used to determine the height of the hopper as it relates to the length of the horizontal pipe and the stack inside I don’t recall the numbers but they can be found on the web pretty easily
The presentation Almost completely missed the point of a rocket stove mass heater and the explanation about the reason it was invented in Africa was just ignorant and insulting
Don’t think explaining where the rocket stove was invented was the point of his video. I do believe he was saying how he heats his shop. You my friend are being ignorant with your comment. I would love to see your version of a rocket stove video and your explanation of what it does and where it originated from.
Excellent details! Obviously a working guy with holes in his jeans 👍 When you disassemble it next time, to clean it, would you please make a video of the inside?? Thanks a bunch!
But who wants to stand there and feed it for hours... not me... make a gravity pellet grate with hopper... runs unattended until the hopper runs empty... geez!
Can you make this burn without attention for six to eight hours ??? What is the steel plate size and thickness ??? How hot does the base plate get ??? Nice video.
Thank you No you can’t leave it a rocket stove requires frequent feeding because it burns very fast The plate is 1/8 inch and does not get very hot there is insulation between the burn chamber and the plate
Vernon you built you RS 2 years ago, how is it doing ? I plan to build mind like yours my friend. I plan on using perlite also. The thing that worry’s means I hear these guy saying They burn out there burn chamber out in a short time.I plan as you to use 4 inch square Tube 1/4 in wall. I know the perlite keeps the heat in the burn chamber, but would that Not make the burn chamber tube burn out Sooner. I,m confused with that? Thank you For all your help.
Thanks for watching Jim My stove has been running well for two or three years with no burn out I recently converted it to be able to use pellets as well. Rocket stoves require a lot of attention while there burning because they burn wood so quickly check out that video the thumbnail is rocket to pellets
When you were starting the stove I was thinking if you had a clean out on the exaust pipe a couple pieces of paper lit and put in would start the flow of air. Or warm the pipe with the torch but that costs money. Most times paper is free.
Thank you!! that is an awesome idea I will swap out the elbow for a Tee with a cap that is removable I have used the torch before but you are correct burning that torch cost money thank you for the suggestion
I don’t know if others are designed the way I have designed mine but I felt it necessary to be able to clean around the base that’s why I made it removable
I seal the cover with fire proof rope typically used to seal wood stove doors. Etc anyplace where a fire proof gasket would be needed it’s the same material
Thanks for watching I wrapped the internal square riser with an 8 inch round pipe, and backfilled with vermiculite then cut a square hole in a pipe cap slid it down over the pipe on the bottom I cover the square horizontal in much the same way with sheet metal encapsulating the entire piece Hope this helps
Alan that’s a great question I don’t see why not but, I would suggest further research on the idea gathering several opinions before moving forward Thanks for watching
@@Hinkleshop Check the channel: mylittlehomestead. They have built a cob bench adjacent to a rocket heater and according to the channel, it is a great success! th-cam.com/video/NYJyxptclos/w-d-xo.html Try the link above, and see what you think.
Vernon, thank you for sharing, great video! Couple things: did you get the tank at a scrapyard, the other steel too? Is the tank literally just sitting on top of the fire rope? I know it is bolted down, but no channel the rope sits in? I want to build one of these for my home in the far north midwest, and this video has been a great help! I would suggest a fresh air in, so it isn't sucking the air out of the shop. I simple pvc pipe run to the outside will bring in fresh combustion air! Thanks again, keep up the good work! Dan
Thanks Dan No need for a fresh air intake my dust collection system for the shop is an open air system. also no there is no channel for the rope it just sits there with fire rope glue to hold it in place while I’m bolting down the tank. The tank was made from an old compressor that stopped working I removed the compressor portion and cut the bottom off the tank The steel for the fire chamber I purchased new at a local metal supply shop it is 1/4 inch thick 4“ x 4“ square tube hope this helps and thanks for watching Also the chamber is lifted off the bottom roughly 3 inches and is surrounded with vermiculite to prevent over heat at the base
@@Hinkleshop Vernon, appreciate the response and further info!! When you say "lifted off the bottom", you mean the large plate that everything is mounted on sits 3" off the floor? You sort of confused me there, where is the vermiculite exactly? Also, do you have the dimensions of the burn chamber, for example, the overall height of the riser inside the old compressor barrel? I thought I read somewhere in the comments that you surrounded the riser with a round 8" steel tube (also 1/4" thick??) and filled the area between with perlite. Did you weld a top plate at the top of the riser to "cover" the perlite? Lastly (as this seems to be a topic of discussion with rocket stoves), how far from the very top of the old compressor barrel does your riser sit? I have read that it should be within 1-2" so that the gases can reburn and not just exhaust. AGAIN, thank you for your responses and willingness to share information!! Dan
@@danielkuczero1991 By lifted I am talking about the 4 inch burn tube that runs horizontally into the tank, I raised it off of the metal plate and put vermiculite under and between the plate and the tube. I used 24 gauge flat stock (sheet metal) to hold the vermiculite in place The eight inch round pipe is standard 24 gauge 8 inch DIA chimney vent pipe I cut tabs in the very top and bent them inward toward the center square tubing and sealed the gaps with furnace cement to ensure that the vermiculite could not escape the riser is 2 to 3 inches from the inside top of the tank
@@Hinkleshop ok, the vermiculite and offset is not visible in the video. thank you again so much for the information!! I can't wait to getting my stove built.....
The rocket stove is very efficient, it does require more attention as it burns the materials quicker than a traditional stove but in a wood workshop that produces a lot of small waste it works very well

Finally someone not pretending to be a rocket scientist with a rocket stove, well done thank you👍
Thank you sir!
I appreciate the compliment and thanks for watching!
Thanks a million for this video. Not exactly the design I've made, but your "J" tube is very similar and a great proof of concept.
You’re welcome thanks for watching!
How large a shop do heat. I loved your video!😋
Thank you the shop is 20x24 with only 1/2” insulation in the ceiling and none in the walls
It would have been cool if you took that tank off and show how the inside worked and how often do you need to clean out the ash?
I’ve run it for two years now and the build up in the chamber is very minimal
I've made the exact same setup, but with a fully insulated burn chamber and riser out of ceramic fiber board, to make the fire even hotter without damaging the steel structure.
My highest temperature ever recorded temperature measured on the top of the gas cylinder was 800 degree Celsius and regularly temperatures above 700, this is measured about 1.2 meter from where the actual burn happens, it melts steal there.
Every few months I need to replace the 2mm walled stainless pipe for my secondary burn because the heat just eats it away, very efficient stove, can run 12 hours one box of wood (10-12kg)
If the inlet pipe is longer for feeding wood for a longer time, will that mess it up?
Thanks for watching
Great question there is a formula for the height of the feed tube in relation to the horizontal and vertical pipe there are several sites on the web to show the math
But I’m pretty sure if the feed pipe is too tall it will not work properly the air flow friction rate will increase as will air blockage by the larger amount of fuel (wood)
What happens if you open the ash hatch open to draw air but stuffed the hopper with wood enough to choke it? Would it draw air from the bottom port?
Yes it will but not as efficiently there is a calculation used to determine the height of the hopper as it relates to the length of the horizontal pipe and the stack inside I don’t recall the numbers but they can be found on the web pretty easily
Thank you

I feed it as I pass by working in the shop all day not really an issue
But I agree the pellet hopper is a good idea

A little bit of wood making a lot of heat…..this makes too much sense……well done ✅
thanks for sharing 👍 just wondering the diameter of your heat riser. tnx
4”square tube encapsulated with an 8 in round back filled with vermiculite
hey, can you post a schematic or diagram? thanks
Vernon you built you RS 2 years ago, how is it doing ? I plan to build mind like yours my friend. I plan on using perlite also. The thing that worry’s means I hear these guy saying

What type pipe is inside how it it attached
Everything is welded. The pipe is 4“ x 4“ square tubing throughout.
@@Hinkleshop Thank you!!

This would have been a great build video.
I agree but that was built before I started doing TH-cam

Thank you again my friend for answering my question so promptly. Your site is one of
My favorite & that is saying a-lot as to how many I have watched.
Happy to help my friend. Thank you for watching in the continued support.
Never knew those barrels were removable. All of them? Heard about removing ashes from front but not back.
I don’t know if others are designed the way I have designed mine but I felt it necessary to be able to clean around the base that’s why I made it removable
A proper rocket stove!
Can you show what the inside looks like please.
Thank you I would Be happy to
give me some time to take it apart and film it
That is awesome pretty simple to build God bless you for the information
To prevent smoke coming back out could you turn on an inline duct fan temporarily on the chimney pipe before lighting the 🔥 🤔. Great video.
Thank you
I think a temporary draft inducer is great idea
No se, para que sirve. No hablo ingles.
It would have nice to see the tank removed how you seal the cover
I seal the cover with fire proof rope typically used to seal wood stove doors. Etc anyplace where a fire proof gasket would be needed it’s the same material
Could you burn waste oil in one of these and get the same effect?
I don’t think so but give it a try I would be really interested to know if it could be done
I'd like to see how you made the chimney inside the tank
Thanks for watching I wrapped the internal square riser with an 8 inch round pipe, and backfilled with vermiculite then cut a square hole in a pipe cap slid it down over the pipe on the bottom I cover the square horizontal in much the same way with sheet metal encapsulating the entire piece
Hope this helps
Hiya, hey could the cylinder be covered in Cobb to give it thermal mass?
Alan that’s a great question
I don’t see why not but, I would suggest further research on the idea gathering several opinions before moving forward

So your propane tank bolts on? How do you seal the bottom man.
Thank you
the compressor tank is bolted down on the bottom with a product called fire rope or fire gasket you can get it from tractor supply
subscribed!
I'm curious, how long is your feed chamber (it looks like 11 or 12 inches)? Also, what angle is it setup at? Great video, thanks.
Its 10 inches tall
OK
I will
