DRTV: Rocket Stoves

[BlanketTruth22]

Thanks for posting this is very nice

[tryin2lhard]

This is very cool, how well has it held up for you?

[DeadlyDad]

One *vital* thing that isn't mentioned here is that the barrel section is actually a well-insulated reburn/combustion chamber that operates at ~1800F, *completely* burning all volatiles. The intense heat is what causes the 'rocket' effect (i.e. hot air rises, and the hotter, the faster), and guarantees that CO levels are less than 10 parts per million in properly designed stoves, because the fast moving stream of air ensures that every carbon atom has *lots* of oxygen atoms to bond to.

[danimossi]

@RA59 there is a strong downdraft pulling air down, hence the rocket name :o)

[yahoopig]

How is your foreskin?

[shartne]

man that is great! what is cob? cement or mud?

[badlegend1]

@shartne Cob is>Cow shit .Enjoy. Basically its shit stucco.It does do the job though, but not a pleasent thought.To me it just shows that everything is usefull,and I am not a tree hugger...lol

[themarkfellows2]

I see cracks in the cob in both rocket mass heaters. Do you ever have a C0 detector in the room to see if you get any carbon monoxide?

[hop2freefood2go]

Very Very Very cool...Never heard of this . Thanks so much for posting this.

[RA59]

If you put a long piece of wood into the feed for the stove, what prevents the flame from traveling upwards along the board and into the room?

[DCVU2]

I have 25 fb2 firebricks, and many old solid red bricks. Can I build a rocket stove mass heater with this, or must I buy more firebrick?

[sweatyss]

does this heat your entire house or just the rooms that its in? im definitely interested but i havent heard enough first hand experience to believe it.

Carbon Monoxide?

[forestfairness]

what happens to the design over time as the metal part burns out over time and needs to be replaced????....unless using stainless steel it will corrode over time won't it????....in hawaii metal drums only last a year or two as a wood heater....mahalo and aloha, forest

[Superthecheese]

@forestfairness They do wear out but it takes 10 to 20 years depending on your heat riser setup. I would not incase my drum as they did due to fear of replacement. The cleanout is easy with T joints and ash pan. It takes all of 10 minutes once a week or if the ash pit gets a bit deep. Cleaning out the verticle or external sections once a year with a sweep will be just fine. If you don't care about your neighbors just sweep it and hook a leaf blower to the intake! Ash Cloud!

[wileyisme]

why are you wearing insulated coverall's and gloves in the house, how in the hell are you going to clean out the chimney, it still has to be cleaned it is not 100% efficient, why is the big cracks in the cob. It is cool looking but there is better more efficient way's of heating. what if you don't like cob i live in the mountains a friend of mine has a new home with rocket stove, i have old house custom built stove. His house is freezing compared to mine and i burn 3 cords a year compared to 8.

[kenfo0]

that is a rocket stove based mass heater. a rocket stove can be as simple as a double walled tube sitting on top of a slightly raised grate. This would NOT be an efficient room heating device, where your mass heater is.

[cliffcox66]

will the cob or insulation eventually crack and fall apart?

[proutsos]

I guess he uses the little door in the front to scoop the ashes from the horizontal section out, but doesn't the burning suck all the warm inside air and send it out much like a fireplace? An external air feed would be nice!

[MultiDillHole]

Hey you could combine the rocket stove with a circular building. Put a living roof dome on the top and a revolving door entry...The out-gas heats the entire structure like a heated-floor/heated-wall building, and the intake comes from ground-level. No idea how to clean it but having 8 or so intakes and 8 or so outlets would ensure it runs for a while. Maybe in the summer when it's not in use you could fill it with carbon-eating microbes or something like that.

[madmanmapper]

less pollution? couldnt you just burn ethanol? or natural gas? or make a solar oven or something...

[jmg1957]

well done.

[megalisstudio]

cool idea man

[TheWaggaBloke]

G'day I Love this kind of stove heater! I've been looking for a stove Heater to put in my 33ft by 30ft shed mainly to heat this area I think this kind of heater stove will do it. thanks for posting video's. do you think it will do the job. Rod

[PigNorton]

How much to have you design and build me one ?

[greenteen85]

the name got my attention

[Amishmenno]

Do you have some prints or something available?

Where can I get some basic designs to build this stove?

I would like to think if this would work in another country.

[WoodBClayMaster]

I have watched almost all of these videos, & have been wondering what happens, when the stove burns out, do you replace it or could you before you build the stove, add a refractory brick in an oval "tube" with exhaust vents at the top to transfer the actual heat to the sides of the barrel & the exhaust gasses are then moved through a ceramic tube with a cleanout, to the chimney.....I am merely curious!

[DaleZiemianski]

I've been hearing about these all over lately. I love the concept. You don't need to use a chainsaw to cut up logs or split logs into burnable size, just clean up the debris from your woods and burn wood small enough to break across a rock. No more dependence on gasoline to run a chainsaw.

[histerics3]

What temperature are your homes typically at in the winter with this device?

[goandfuckoff]

Ecojizzmops.

[breezyage]

You look very cold. Is it not giving enough heat for the room?

[pauluminous]

The plus of having  a rocket stove is that it's so fuel efficient, it gets so hot that creosote and smoke are hardly a problem.

[adamatova]

Doesn't your place get smokey or sooty with it?

[birdland5]

Don't you get creosote buildup in the stack? How do you clean that long horizontal run out?

[SIDSmom]

this has been the toughest question for me to find answers on. even if there is a negligible amount of creosote, i still want to be able to clean the flue regularly.

if anyone knows where i can get answers shoot me a pm

[petthekittyz]

@birdland5 the combustion is much hotter, and alot less wood is burned, cleanup shouldn't be needed for a long time

[tulsavintagedigital]

@birdland5 Rocket stove burn in excess of 1200 degrees F... unlike conventional wood stoves, the smoke is so completely burned all you MIGHT ever see is a little bit of ash in the flu. In fact, the only time you should see smoke exiting a rocket stove chimney is a short time after it is lit. Once it's really going all the is coming out is CO2 and water vapor.

[AOZXRAY]

@birdland5 It burns so hot and clean that creosote doesn't accumulate, I have heard.

[lakewood85]

My two gas fired, forced air heaters have you guys beat hands down for comfort and fast heating.

[pauluminous]

@lakewood85

Dude, really? No shit! Did you build the air heaters yourself from scrap, or are you leaving a major carbon foot print? You're still dependable on being on the grid and paing a gas bill.

[lakewood85]

Dude, actually you would be better off to heat with electricity. Base load power plants generate all the power you'll ever need and then some. By the way keep pumping wood pollutants into the atmosphere you dope.

[pauluminous]

Base load power plants still (for the most part) depend on coal, a non-renewable energy source.

They're about 31% efficient, which mean 69% of that fossil fuel is wasted. Plus the fact that it costs around US$1300 per Kw just to build. A energy satr rated fridge still uses about 400 kwh/yr.

The great thing about a rocket stove is that it's so energy efficient due to the extreem heat that there will be hardly any pollutants left.

[terrabugz]

please explain the massive crack in the wall where the flue turns up toward the roof. not a very convincing masonry job. scary to think of an interior crack in a masonry flue?

[Luminaring]

Is the advantage of continuous wood feeding, say, during the night, unique to only the 'rocket stove'?

[mrJOEmann]

how do you clean inside of it after a lot of use?

I love your idea, but where are the challenges to using it?

[pyroman675]

@mrJOEmann @birdland5 its sopose to burn so clean there is no soot produced or ash, the only thing that should be coming out of a good rd CO2. ocket stove is steam an

[pyroman675]

[dead4fun]

@mrJOEmann I have one of these in my home and the temperature inside gets so hot (over 1500 degrees) that there's very little to clean if anything. Granted, I've been using mine for 14 months, but if built properly, there shouldn't be anything to worry about for quite some time.

[DeadlyDad]

@mrJOEmann Basically, you need to take it apart, which isn't as impossible a job as it sounds. permaculture. org. au/ 2011/10/31/ rocket-stove-water-heater-redu­x

[livingonsolar]

Great video showing a good idea.You are thinking outside the box and seeking new ideas about how to do things better. You are also taking it to the next step by building it.

[JimmyRiotNY]

Great, thanks guys!

[Bently100]

I must say though, that the way you are dressed suggests that it is not very warm in that room!

[tribalwind]

very impressive, i really like the larger/taller infeed area of the first stove,allowing for that large half-log to be fed in, looks like it would burn for hours on end without needing to feed more in each hour or so as other designs ive seen.

about how long does that go for generally speaking? also see theres open space below,and a front hatch(for fire-starting and cleaning i presume?)

[josuha2006]

I built one for grins and chuckles.

Maintainance is a pain and loading and cleaning is more than a regular stove.

I agree with deeynar.

My old Oley wood stove outperfroms it hands down.

Cobbling a stove from junk is ok for a barn, but not a house.

If you want a cheap date for a camp stove or barn, Northern Tool seels a kit that you can make a stove from a 55 or 35 gallong drum.

[kenfo0]

@josuha2006 the entire pt of this device is that it stores heat for a long time, burns less wood than a typical wood stove and costs very little to build...just time and knowledge. I have no idea what an "oley" wood stove is or what it costs or what it's emissions are. The setups in the vid typically have very little smoke and the exhaust is relatively cool...down to 120 deg or so. What maintenance are you talking about? How would it be different than your wood stove?

[deezynar]

I removed my previous comment because it seemed shrill & some may have ignored what I was saying because of how I said it. Let's try again. Fire produces gases that are extremely toxic. Building codes take this very seriously because lots of people have died in their homes from carbon monoxide poisoning. Don't gamble with the safety of your family by building a tinkered together furnace. If you want to experiment, at least study the safety ramifications first, and use proper materials.

[1dschamp]

You seem to be ignoring the fact that these stoves are alternative in nature, though have been proven in real world applications. If you think the stove can't work or would pose a threat to safety, please be specific rather than making general statements about technology you don't understand.

[deezynar]

I didn't say they don't work. They do indeed work very well. My point is that thin mild steel corrodes under high heat and moisture conditions. The units shown run thin metal flues horizontaly for great distances increasing potential for moisture induced corrosion and flue leakage. The hazard is increased because they can't be inspected for leaks. Address those issues and all is gold. I should have written a second comment to make my meaning clear. Thanks for prodding me to clarify.

[kenfo0]

@deezynar you are 100% correct.

[Anothercoilgun]

The human mind is wonderful.

[WoodBClayMaster]

My only concern is, how do you clean out the smoke stack?

[FADNaR]

дайте переводчика!!!

[enjoistaind]

Thanks for showing us that natural, conscientious living doesn't have to be synonymous with poverty.

[jbloch69]

Have you read about the way mud ovens are made using a clay sand mix, enough clay for a small ball of clay to hold together and enough sand to keep it from squashing if droppped from the hip, th e first layer with al little hay ,as a heat accumulating layer and clay with more grass in it as a insulating layer all made with no tins, couldn't a rocket stove be made like this, like a mud oven? rose macaskie.

[jbloch69]

There are comercial masonary stoves they are expensive. A masonary stove is a sort of posh persons rocket stove . i reckon a rocket stove is a hoboers masonary stoves, masonary stoves store heat in their walls and have secondary and tercery combustion chambers that give as clean a burn or cleaner than rocket stoves do. Youv'e reinvented the masonary stove. and made it look easier to just try to do and made it beautiful in mud. rose macaskie.

[Textynn]

Where the heck do you get a barrel like that??

[steveastrouk]

It looks like a 55 gallon oil drum. People will plead to get you to take them aware.

Steve

[benthejrporter]

Good idea! Well done! Just watch your back because the power companies will be after your ass!

[lmyhoosier]

lol, if every one did this the power companies would go bankrupt

[benthejrporter]

That's what they're afraid of... and of all of us becoming free of course!

[borcer]

This is great!

[starzine]

awesome! I think I may build one this summer...thanks for sharing this info :)

[bdmenne]

I really love you guys. Your energies are so attractive and inviting. I am so happy with the work you are doing and then promoting by making videos. You will help change our world with every person who sees this. Love, Bryan

[syamasundaradasa]

Love it.

[gift3rs]

Makes me wonder why there arn't commercial rocket stoves that are avalible, I mean it might be a fun project, I just don't want to do it. But I'd probably buy one if reasonably priced.

[pabbananna]

that rocks. making the flue long and packing mass abound it is the way to go. i always wonder why people vent it out as fast as possible.

how do you clean out the ash deposits in this installation? it looks pretty impenetrable..and what kind of building permit issues do you have with this?

[casinnova2002]

yeah... how do you clean it? does all the ash stay in that first chamber?  and why do all the dudes on all these natural building videos sound so gay?

[LarsMith217]

Thanks in part to this video, I was empowered to design / build my own rocket heater, which you can see by searching for :

Rocket Mass Heater

[LarsMith217]

Watching this video helped me learn more about how to build my own heater, tho with my own design differences. Check it out. Search for it here on YouTube by searching for

rocket mass heater

[quantummom]

awesome!!! If I want the stove in the middle of the major common area in my house, would that be ok? I mean, I don't see by logic and practicality why not, but if anyone has any insights otherwise about the plan for my home, would you kindly enlighten me? Thanks my brethen.

[WorldStove]

mmm on a cold foggy day like today that bench looks dreamy

[Quintadaflores]

Wonderful because of its simplicity. Any idea where I can get instructions on how to build it?

[CityzenJane]

Very cool! You guys - it is so impressive what you have accomplished since 1998 when I visited!

10 years ! Wow can't believe it's been that long. Maybe time for another visit!

[geekguyandy]

It says the video is unavailable :(

[bluzy25]

do you have a instruction for building this stove?

[Cr8Joi]

I want a rocket stove too! I want the flue to go

under my bed so when I climb in at night I'm all toasty warm. I wonder if city building codes would allow it.

[WilliamCerf]

I want to let you guys know that I've subscribed to your channell. You are doing such great work to get the word out about Dancing Rabbit, Sustainable Living and Intentional Community. Great job!!
