Not sure why the algorithm brought these two videos up after so long but that's okay. The first one reminded me of a fireplace in my parent's home that I minded growing up. Forgive me if I get the terms wrong after all these decades but it heats the water for the house and radiators. Big copper water tank in a closet. The fireplace had a back burner that I would stuff full of sawdust and then just a regular fire in the front. Boy could I get that thing roaring. Sometimes I'd have to go run the hot water as the boiler would start making noises. lol. We cut reject timber from a saw mill. Taking home a huge trailer load at a time. That's where got the sawdust. We also got big trailers of off-cuts from the local kitchen furniture factory. Lots of laminated plywood to chop up. Fun! And finally we also for a few years went up the mountain to stack and dry turf for the fire. Mom went to oil heating when I went off to college. lol.
Very good presentation, I had no idea people living in cold areas have to go through so much efforts to warm up their homes until I watched this. . I am living at the equator.
Very nicely done. I feel like someone who has been furniture shopping/ kicking tires for weeks and with your video finally found exactly what I need and want. Great comment on the fresh air supply as some HVAC guys think it is only to decrease stuffy air in a home and are unaware it decreases cross drafting on cold air from leaks if your returns are deficient. (speaking of myself lol)
The farmers in northern Japan use a stove similar to yours. One thing they do that you did not mention is they heat water as well as heating the building. This was told to me by someone that lived on a farm in Horkido, Japan.
Thank you very much for such a comprehensive video. I'm dyslexic so find written instructions difficult but I was with you through every part of the construction. I will be building one of these very soon
Been working on a rocket stove for the trailer. Now I am thinking of a mod thanks to your vid. I don't have a ready access of saw dust but tons of dry pine compliments of the pine beetle, lol. So I am thinking of a wood shipper to make chips and burn. We are looking at a Cob renovation on the trailer. You should look into cob houses. I just learned about them last week. People are running their smoke stack through Cob couches and even floors before it runs up the chimney. Lots of great ideas. Let your imaginations soar! Still thinking. Thanks for the video!
Great. I've seen (YT) and know the principle. Your practical 'demo' fits my lack of fantasy - I really could use some warm in the winter though I've little sawdust, so I'll follow your work pattern. Love the rib on the door - its born to fit that way! Thanks for sharing the fun, and the 'eye' I seem to lack. Together we're much stronger.
Not bad atall. I've seen a few versions of this around, usually using a 20 gal barrel for the sawdust charge.If you use a wooden rod, rather than a pipe for central hole, put a slight taper on it. It makes it easier to remove without disturbing the sawdust. Another possibility is to attach angle irons to the outside barrel, think radiator fins. If you attach sections of angle to the inside of the outer barrel, at an angle, you increase the air turbulence. This will help insure heat transfer and help with burning the combustibles.
Thanks! That's a great video. Good presentation also. I would make a plywood disk with handles to pack the sawdust and maybe buy hinges & latches but other than that you hit a homerun with me with your sawdust stove.
Hello.. nice set up.. I have built a few of these and found waste cooking oil mixed in with saw dust before packing will add alot of BTU out put, I built one with a 4 foot diameter cattle trough too
What a brilliant idea. If I can find the right parts I'm making one of them. We keep Gerbils and they use sawdust and paper/card bedding which has to go in the bin. I could heat my garage with it instead. It sure beats the gas cylinder stove.
great heater , like how you put the flue lower and the deflector to stop heat going straight up. i will make this for greenhouse/ add Gerrysdiys oil burner for when i have no sawdust and I'm Good. Thanks heaps
Outstanding video. I'd love to be able to retro fit this idea into an existing wood burning stove in my basement installed by a previous owner. Loading sawdust burn logs (buckets/barrels) seems a whole lot easier than dealing with the whole firewood cycle (cut/spilt/stack/haul/stack/load/burn/ash disposal). I can get tons of sawdust and used cooking oil in the area. Thanks again and keep up the great work.
Well done! I am so intrigued by your build that I am...as we speak building one myself. I will make a few changes but basically I like what you have done. Keep up the great work.
I'm amazed at the ideas that you come up with. For those of us who don't have access to saw dust, I'm wondering if you designed an affordable pellet stove.
Good job! I think that if you tumble your sawdust with a little waste oil, you'll be able to pack it better. Also, I'd pour less in, before packing. You'll get a tighter pack and longer burn if you pack it in smaller amounts at a time. The oil should ensure a complete burn, even with a tighter pack. Also, now you have ashes to put on top of the next burn. :)
hey my friend. One of the best vids so far! 2 things. 1. how about a restricter plate to adjust the air flow going in to slow down the burn and last longer? 2. How about a donut size steel plate to put on top of the saw dust to keep it compressed as it's burning? Again. Great video!
I do have a damper on the intake. Really no point in continually compressing the sawdust, it would more than likely collapse it into the center and choke off the fire.
Very nice! I can you put a lot of thought into it and it paid off. I'm going to have to make one for my shop, I have plenty of hardwood sawdust from my wood working and part of my sawmill.
No problem. My brother has a workshop that makes a lot of sawdust. It would work perfect. I tell him not to waste it because then he could get some heat. He wastes it anyways. We have enough sawdust in the shop now to fill probably 3 of those barrels. lol. How would sawdust work in a wood burner or pot belly stove? I'd imagine it would smolder a lot.
If you had to build over again would you put your chimney lower to the ground and would you weld a quarter inch thick piece of steel to the inside of the lid to help absorb some of that initial temperature? Think this thing is safe to put in your basement and sleep above it? Looks like a really good way to use up lots of sawdust and eat your house good job!
+Pete Lasko I wouldn't go lower with the chimney as it "may" want to pull air through there and push out the intake. A 1/4" plate on the top and or bricks stacked on the lid to retain heat would be a good idea. It will work like any wood stove.
sixtyfiveford yeah but i dig an know i know how to make one if i ever move to a place where id freeze me nutz, now im a head of the came an can have roasty nuts lol
you should see about making a horizontal flu pipe to make some sort of bench or something to make it hold heat for a little while longer, been looking at all sorts of rocket stove ideas and this one is unique i like it, keep up the good work !
Thanks. The efficiency of this stove makes so the flue temps are extremely low. Unlike a conventional rocket stove or wood stove that looses a ton of heat up the flue that can be captured, this looses virtually nothing. I guess a stone/mortar top could be put on it to retain heat longer.
I like what you have done. I can think of some improvements. i.e. Weld a quarter or three eights plate under the lid so the lid doesnt burn out and so the heat is retained for longer. The inner barrel could have a reducing cap so that the flame size is reduced
***** You need the heat to escape so any panels inside the lid would force that heat out of the flue; not good. If anything fins need to be welded to the outside of the lid to dissipate more heat. The lid is sacrificial but can easily be replaced or repaired when it does burn through.
@@sixtyfiveford Actually, the plate could be a good idea, and you could put pipes on the underside of the lid. Elbow joints on both ends of each pipe would go to open nipples that go through the lid so that plenty of heat is still released out the top.
very cool (or hot if I were Paris Hilton LOL) My rocket stove doesnt really work that well. Dont know what I did wrong. Oh well I got to many other things to work on. That amazing how long it burns and I bet if you run out of saw dust you can go to cabinet makers and get all you want for free.
Since the chimney temps are so low it lends itself very well to a tent or tarp enclosure. It puts out a good amount of heat even if its out in the open and you can feel it standing 4 feet away.
the more I think about it this is a perfect heater for a green house if it can stay hot for 8-10 hrs and vent through a flew that's all you need for overnight heating so I will be building one after the greenhouse is built later this summer thanks
About to buy a sawmill and was looking for either a way to turn sawdust into logs/chips for heating my shop with but this would work just fine other than the lid that thin would burn out within a month, needs a thick plate welded to it on stands so the thick plate could take the direct flame and spread it to the lid imo. Good idea though thanks.
just a thought but what if you ran some flexible copper tubing around the burn barrel that ran to an external radiator. if you filled it with water the convection of the hot water should circulate it and you could either have a water heater or a secondary heat source to increase efficiency. im thinking something along the lines of the woodburning hottub designs. This is a great idea i have a woodshop that creates alot of sawdust occasionally i can fill a 55 galon trashcan in a weekend now i might find good use for it!
My dad did this 25 years ago I remember because every night I had to fill the inner barrel we used to burn it from 6 pm and it would still have got ashes next day at 6 we would compress the saw dust real good stomp it down and then water the top of the saw dust or use fresh saw dust from fresh trees being still wet not dried out completely
+Leo Waisanen Yes, you can throw chunks of whole logs in and around and fill in the spaces with sawdust. This will increase the burn time by a few hours. You can also saturate the sawdust with old cooking oil or motor oil, this generally doubles the burn time.
Enjoyed Muchoes. We live north of the 54th and heat , with wood, 7 months of the year. Wonder if this will work with chainsaw cuttings ( dried) since we also have a greenhouse. Hmmmm?
What tool did you use to cut up the steel drum? I need to cut the bottom off two drums, and don't know if an angle grinder with cut-off wheels would do the trick.
Great build. A couple questions about it. Where do people get sawdust the quantities needed to run this stove? It's not UL certified so how does the insurance deal with this? This is a major issue with most of the home made rocket stove on youtube. It's a shame too. These things are great and rocket stoves are safer than fireplaces and wood burning stoves.
@@sixtyfiveford True. But what about the insurance and UL. I'd love to have two of these things so one burns and the other is loaded. Once before work and once when I get home. Just keep switching. But if insurance says no, then it's not going in the house. Too bad. It looks great. It's the same thing with regular rocket stoves. I would like the UL and insurance to actually go to a workshop and see how these are designed and built. Then stick around for the demonstration of how they operate. They ares so safe to use with no creosoting in the flue.
This is a fantastic build. Is there any suggestions you could make for a safe build say for a house? I thought of putting it down into a concreted well pit kind of structure and just run underground ducting into the living areas of my house. The extra thermal conduction from the ground would maybe even surpass your 13-15 hour experiment. Would love your input about the alternate method for household use.
It would install the same way you put a wood burning stove into a home. I did design it with a fresh air intake for higher efficiency but that could be left open. By using the flue I can get even longer burn times, but you cut down on the BTU it is putting out.
It will burn anything: wood pellets, leaves, dried plant matter, larger pieces of wood, cutoffs, oil soaked sawdust or whole logs and it burns just as well. My design is virtually 100% efficient and burns all the wood gases along with the wood itself.
Nice work ,you don't mention how you use the butterfly control on the output side, is there any merit in controlling the air going in as in a traditional wood burning stove ? I'm just making one right now and wondered if there were any modifications that you would like to have included that you are saving for the 'mark 2' model. Many thanks, looking forward to a warm workshop.
That is so interesting man, especially with how much energy is radiated out before exhausting the stove...wow. My main concern is safety, how are you sure it's safe and what prevents some of the ash causing bad creosote build up? I'm just asking, I think it's a brilliant idea! This would work well if you had two of these working in tandem in a greenhouse setup I think...
Creosote is caused by an incomplete burn. A typical fireplace puts a lot of heat up the flue and with heat is unburnt wood/wood gas which causes creosote buildup. By having a higher burn chamber I'm getting an almost 100% complete burn, therefore burning any creosote.
I agree with the comments below. It’s a damn fine idea just have a question. How many burns did you get out of the inner and outer barrels before having to replace them?
Wow, What a well thought out design. The craftsmanship was of high grade. I was wondering if the input air tube had a damper to control the rate of burn? Was the 10 hours of burn at full air? After 3 years do you still use your heater? Thank you very much for the video. al
Thanks. I do have a damper on the air intake and the 10hours was full open. It is still in working condition, but I don't use it too often as it was just a fun project/idea I had.
Thank you very much for such a comprehensive video. I'm dyslexic so find written instructions difficult but I was with you through every part of the construction. I particularly liked the door and its latching mechanism, very clever, elegant and practical. I had seen a video of a finished sawdust burner and had already got hold of a 55 gallon drum and had been designing in my head the various other aspects but now, with your delightfully presented construction I'm not going to make all the inevitable errors I would have done. May I make one suggestion; where you use four legs three might be more practical. A tripod is always more stable than a four point support. Thanks again.
Thanks. It will burn anything: wood pellets, leaves, dried plant matter, larger pieces of wood, cutoffs, or hole logs and it burns just as well. My design is virtually 100% efficient and burns all the wood gases along with the wood itself.
So with this set up you can not reload tell its out fully right. Could you build a 2nd small barrel pre set it up with saw dust then just pull the first out you & drop in the new full one?
id love to make one,just dont have access to saw dust.the only different thing id do is make a press for the sawdust,i think it would burn longer and would hold more.
So, 6 years in are you still using this stove, or at least one of this design, for heating purposes? If so, how is it performed long-term? Maybe an update video?
I use it on and off and pretty much just built it to see if it would work. It was mainly for workshop heating but I moved it due to not have work space that accommodated a wood burning stove. It still works great however I would only make one modification and when/if I put it back into full service I would do this. -Add a second flue at the top that can be closed once the fire it burning consistently. Then the lower flue can take over. This is only because it takes a little practice to get the heat to want to draft up the flue since it's so low on the body. Once it's running it has no issues.
Interesting. But, for this to have much functional utility, you would need to have one heck of a lot of sawdust. Even one month's worth of sawdust would take a lot of dry storage space. How the heck would you store so much sawdust? Would the stored sawdust attract varmints or termites?
I always say to myself I'm going to bed but then I watch your vids then I'm up for 2 more hours love them great work
Thanks...

That is just awesome! Anything you can load once and it will burn all night long is a winner in my books.

Enjoyed Muchoes. We live north of the 54th and heat , with wood, 7 months of the year. Wonder if this will work with chainsaw cuttings ( dried) since we also have a greenhouse. Hmmmm?
Yes, Chainsaw cuttings work really nice.
like it a lot, I am waiting for the next episode.
Thanks for the feedback. Hopefully I'll have a good test video up within the next week.
What tool did you use to cut up the steel drum? I need to cut the bottom off two drums, and don't know if an angle grinder with cut-off wheels would do the trick.
I used a plasma cutter but cut off wheels work great or a sawzall would be faster.
Great info, thanks for the reply!
Yeah, I have used 100's of the 1/16" cutoff discs on my 4 1/2" grinder and they always work great.
Very nice stove. And inexpensive to build. How big of an area can it heat well?
Should have no problem with around 1000 square feet. If its a well insulated maybe 1500-2000sq feet.
Great build. A couple questions about it. Where do people get sawdust the quantities needed to run this stove?
It's not UL certified so how does the insurance deal with this? This is a major issue with most of the home made rocket stove on youtube. It's a shame too. These things are great and rocket stoves are safer than fireplaces and wood burning stoves.
Cabinet shops have endless amounts of kiln dried sawdust for the taking. You just have to ask.
@@sixtyfiveford True. But what about the insurance and UL. I'd love to have two of these things so one burns and the other is loaded. Once before work and once when I get home. Just keep switching.
But if insurance says no, then it's not going in the house. Too bad. It looks great.
It's the same thing with regular rocket stoves. I would like the UL and insurance to actually go to a workshop and see how these are designed and built. Then stick around for the demonstration of how they operate. They ares so safe to use with no creosoting in the flue.
Nice little stove!
Thanks. I'm glad you think so.
Friggin cool bro. Love your videos!!!!!!!!!!!
Thanks Man. This was a fun project.
This is a fantastic build. Is there any suggestions you could make for a safe build say for a house? I thought of putting it down into a concreted well pit kind of structure and just run underground ducting into the living areas of my house. The extra thermal conduction from the ground would maybe even surpass your 13-15 hour experiment. Would love your input about the alternate method for household use.
It would install the same way you put a wood burning stove into a home. I did design it with a fresh air intake for higher efficiency but that could be left open. By using the flue I can get even longer burn times, but you cut down on the BTU it is putting out.
Great stove, you should market them.
Do you only have to use sawdust or can you use something else like wood pellets?
It will burn anything: wood pellets, leaves, dried plant matter, larger pieces of wood, cutoffs, oil soaked sawdust or whole logs and it burns just as well. My design is virtually 100% efficient and burns all the wood gases along with the wood itself.
Could you cut a piece of steel to put on top of the sawdust to keep the top from burning? Would the fire eat the steel after a while?
Love2boat92 It doesn't hurt it to burn off the top layer. Any weight put on the top will extinguish the fire once it gets to low.
That is true. I never thought of that. Thanks!
You got a good idea. Can I ask how many hours will work After One charge?
Nice work ,you don't mention how you use the butterfly control on the output side, is there any merit in controlling the air going in as in a traditional wood burning stove ? I'm just making one right now and wondered if there were any modifications that you would like to have included that you are saving for the 'mark 2' model. Many thanks, looking forward to a warm workshop.
Michael Sherwin Everything works like a traditional wood stove. I wouldn't change anything.
Do you have a detail drawing of the Saw Dust Heater
Awesome job!
That is so interesting man, especially with how much energy is radiated out before exhausting the stove...wow. My main concern is safety, how are you sure it's safe and what prevents some of the ash causing bad creosote build up? I'm just asking, I think it's a brilliant idea! This would work well if you had two of these working in tandem in a greenhouse setup I think...
Creosote is caused by an incomplete burn. A typical fireplace puts a lot of heat up the flue and with heat is unburnt wood/wood gas which causes creosote buildup. By having a higher burn chamber I'm getting an almost 100% complete burn, therefore burning any creosote.
I thought this was true, I just wasn't sure...I'm super impressed with this thing man. Very nice.
Wonder if putting stainless tube in middle with holes could you burn bigger stuff. This was very interesting.
You can stack logs in, logs and sawdust, leaves, or anything else. It will burn anything combustible.
Thank you
great build I tried one myself to go in the green house. but smokes the whole time. is this usual? or did I do something wrong?
+Ronnie b If the sawdust is still wet/green it can do this.
i would make a press to pack more saw dust,i feel it would burn longer
I agree with the comments below. It’s a damn fine idea just have a question. How many burns did you get out of the inner and outer barrels before having to replace them?
The inner barrel and lid should be on the only real wearable parts. They should last 3-4 seasons before they need patching.
great job great video, i wonder how much hot water that could produce
mic363 A TON...
Wow, What a well thought out design. The craftsmanship was of high grade.
I was wondering if the input air tube had a damper to control the rate of burn? Was the 10 hours of burn at full air? After 3 years do you still use your heater? Thank you very much for the video.
al
Thanks. I do have a damper on the air intake and the 10hours was full open. It is still in working condition, but I don't use it too often as it was just a fun project/idea I had.
Thank you very much for such a comprehensive video. I'm dyslexic so find written instructions difficult but I was with you through every part of the construction. I particularly liked the door and its latching mechanism, very clever, elegant and practical.
I had seen a video of a finished sawdust burner and had already got hold of a 55 gallon drum and had been designing in my head the various other aspects but now, with your delightfully presented construction I'm not going to make all the inevitable errors I would have done.
May I make one suggestion; where you use four legs three might be more practical. A tripod is always more stable than a four point support.
Thanks again.
thanks, great project. have you tried that with any other type of fuel logs pellets ect. work great with saw dust.
Thanks. It will burn anything: wood pellets, leaves, dried plant matter, larger pieces of wood, cutoffs, or hole logs and it burns just as well. My design is virtually 100% efficient and burns all the wood gases along with the wood itself.
So with this set up you can not reload tell its out fully right. Could you build a 2nd small barrel pre set it up with saw dust then just pull the first out you & drop in the new full one?
You can pull it out before it is totally out or even refill it in place. Yeah, having a second burn barrel would be ideal.
id love to make one,just dont have access to saw dust.the only different thing id do is make a press for the sawdust,i think it would burn longer and would hold more.
Great video. Job well done.
Thanks, I'm glad you like it.
So, 6 years in are you still using this stove, or at least one of this design, for heating purposes? If so, how is it performed long-term? Maybe an update video?
I use it on and off and pretty much just built it to see if it would work. It was mainly for workshop heating but I moved it due to not have work space that accommodated a wood burning stove. It still works great however I would only make one modification and when/if I put it back into full service I would do this.
-Add a second flue at the top that can be closed once the fire it burning consistently. Then the lower flue can take over. This is only because it takes a little practice to get the heat to want to draft up the flue since it's so low on the body. Once it's running it has no issues.
. Nice! ? Did the draft send a lot of unburned dust and sparks up the flue? Thumbs up!
Thanks. It didn't send any sparks or unburnt sawdust up the flue. It smoked a tiny bit for the first 5-10min like any fire but then cleared right up.
This is beautiful
Thanks, I'm glad you liked it.
Thanks for posting! Love It!!
Do you burn pine or hardwood sawdust? If you just burn pine, wood it not cause a creosote buildup in the flu?
Interesting. But, for this to have much functional utility, you would need to have one heck of a lot of sawdust. Even one month's worth of sawdust would take a lot of dry storage space. How the heck would you store so much sawdust? Would the stored sawdust attract varmints or termites?
