Building a Rocket Mass Heater

[@dovetailjointfan]

I enjoyed the teamwork by everyone. Authentic people, bless you all.

[@itchyego]

Love this video, all the people that helped make this is so cool! Learned a lot! - Ken in Hawaii Oct 2016

[@Ihaveausernametoo]

You need insulating material especially in the heat riser, but also optimally in the burn chamber. This will not burn clean/effective. And air-vent is needed at the bottom. Benefit with the sand is that you can change it. Vermiculite is good for the heat riser.

[@frantzjensen3983]

Carbon monoxide is what is expelled you need to vent that out side the green house, second make a lid for the burn chamber, so you can adjust the air flow too, the intake is ok size, but when you want to keep the mass hot / warm you will need to close off the intake all the way a steel plate resting on top will work. wish you luck.

Dumb people heard "dumb". Self confidence is weak in this one.

[@magtour]

I thought he said, “dumb”, as well.

[@stephen12264]

@@magtour he did say dumb people i have listened to it several time's it comes out the same. To me if he had said that to me or anyone around me he would be picking his teeth out his ass.

[@LadyG228]

I too thought he said dumb people...

[@pologenius21]

that's some beautiful community work!

[@HomesteadOC]

Ive read that sand is a better insulator than thermal mass. Which is probably why you used it in the riser. Why then did you use it in the bench to surround the rocks and flu pipe?

[@deanoboland]

Great work on video mate thanks

[@feedingfrenzy4114]

I just made mine out of all firebrick. We will see over time what happens. Its working great for now.

[@MsLibrazen]

this is a great idea! thanks for sharing!

[@TaintedMojo]

They’re releasing the exhaust indoors?

[@gg-gn3re]

it builds a layer of strength in your lungs

[@jamesglenn520]

No worries 👍 They are using Galvanized HVAC Ducting for stovepipe. When they are talking about the smell it's the Galvanized coating burning and gassing off which is TOXIC POISON ☠☠☠

[@johnlbales2773]

The cool heater exhaust leaves open the question of chimney deposits such as creosote, and reliable measures for cleaning such combustible deposits to reduce the risk of chimney fires. from Evans & Jackson, Rocket Mass Heaters, p. 93

[@zmanstrong41]

Looks like a group of Holy Ghost filled believers!! Cool

[@chriswalport2979]

how you clean out the ash?

[@BIGDADDY-jp7xq]

yep

[@machiavelli850]

Even after it was "fixed" you can still see it puffing smoke out of the hopper. It's still not drawing enough.

[@asiangoddess4606]

I noticed that you have forgotten to make a air vent door before the fire pit. This air vent door is to open and close to allow airflow that will feed the fire or lessen the fire. Its also where you will remove the ashes. If the air passage vent was big enough, you can actually bake in it. You didnt need to cut down the barrel, it was the missing air vent passage that you did not make that's causing the smoke and not allowing the wood to burn consistently. As per Joe, you have gone as far as making the vent right up to the open roof, you MUST still vent atleast 3 ft PASS the roof to be absolutely sure to clear C02. This is health concern and should be completely finish. I love what youre doin for the greenhouse to help community, but Please do a bit more research before lighting up and check and take all safety precaution. Thank you and God bless.

[@gjh42]

You do not add a separate air vent at the base of the feed tube - that will allow the flames to climb up and out of the feed. The draft going down the feed tube is essential to proper operation. There are published solutions to most all problems with a RMH, depending on the setup. As mentioned elsewhere, cutting down the barrel was exactly the wrong solution - the heat riser should have been extended. The taller the riser, the better the draft it makes. In short, do not depend on this video alone for planning your own installation.

[@machiavelli850]

Angelia Odiame Have you ever build one of these before? Most of what you said doesn't pertain to rocket mass heaters.

[@hebekiah3623]

CO^2 and humidity good for greenhouse. May want to open a door before you go in... oh yeah, you have to.

[@ليثعلي-ف9س]

Asian Goddess ج

[@hebekiah3623]

@Alain M co2 denser than oxygen so top venting not helpful. Hypoxia not likely because just opening the door would mix air to some degree and allow escape of CO2. But then again, if someone decided to sleep in their with no ventilation or mixing of air (like a fan) it could be bad. Hemp growing and processing warehouse like buildings are required to have fans.

[@francescocelentano2376]

great video!! thanks for sharing !! ps: i had the same prob with that gap ;)

[@benvonjerry5136]

Use water as the mass. IT is much more effectiv and times cheaper

[@2primateswalkintoabar61]

Frozen water breaks whatever it's held in.

[@vitasteel174]

Not if you build it technically correctly :)

[@wayneirvine7653]

how long did it take to figure out that all you needed was a small hole under your fire that you can close and a metal top

[@smeglips]

+Wayne Irvine Thats exactly what I was thinking the hole time.

[@wayneirvine7653]

I knew you knew :)

[@jamesglenn520]

It didn't need more air. It needed Exactly what they did! The gap between the riser and the outside barrel At The Top should be 3inch or a little less 🤔 They went from 12 inches to about 3inch and fixed the problem.

[@dickgozinya7169]

you got a couple old guys in there. you know that shiit is legit as hell.

[@feedingfrenzy4114]

+Dick Gozinya lmao!!!

[@awamechanicaldrafting7266]

This is the guy that watches a you tube video and is suddenly an expert.

[@ValiantVision]

All those guys standing around watching one guy work and none of them knew the 2" rule? I bet they gave plenty of useless advice, though. I like the design. Nice job, Rico.

[@hannahavery9877]

run that smoke into a shed and make a cold smoke smokehouse

[@machiavelli850]

Hannah Avery If it was constructed properly, it wouldn't be smoking at all. It should burn so hot that the smoke is all burned up. They exhaust CO2 and steam.

[@smeglips]

+Niccoli Machiavelli his scale is wrong, the fire pit should be a lot smaller this would help aid the air fuel mixture.

[@feedingfrenzy4114]

sand is an insulator. i wouldnt use it on the stove pipe. use more cob!

[@scotts.2624]

+Feeding Frenzy Not somthing you want to use. That riser gets very hot. The cob will burn out very soon. That thin metal pipe will probably burn out within 1 to 2 years and the sand will collapse. It needs refractory cement mixed with perlite instead of sand. Clearly a temporary installation.

[@craigslitzer4857]

Rural Cromagnon You shouldn't have any creosote build up. In rocket mass heaters, you have a chimney fire every burn (on purpose) to extract all the heat

[@antonhelsgaun]

whats the point of the bucket at the fuel intake?

[@antonhelsgaun]

+Anton Helsgaun ohhh

[@snakedroppings9690]

awesome design! but I do ask myself how one gets rid of the ashes?

[@JustinJaybrown]

Make an ash clean out in front of the file feed

[@carlostavares6052]

Great. Thank you

[@karldepauw8924]

the metal heatriser will burn out ,sand is bad insulator ,the transition between the barrel and the pipe is to small,the top gab between heatriser and barrel is only of inportance for direct heat versus slow heat of thebench just my 2cent for fb'ers rocket stoves/rocket stove international if you have any questions

[@jayboog5000]

Yup, about 2 burns is what they're expecting to get I guess? If they had only spent 30$ on some fire brick

[@machiavelli850]

karl De Pauw I've been told that about using a metal heat riser before. However, I used one in my stove (6 inch and 10 inch with clay stabilized perlite between) and ran it an entire winter without burning it out. I guess it still could, but it didn't appear to be even threatening to burn out.

[@feedingfrenzy4114]

+Jason Boulard what did they use?

[@harrymills2770]

There ARE refractory metals that will handle the temps in the riser, but I don't think that's what we're looking at, here.

[@maienduo]

Great job, but please run that steam outside just in case.

[@Mr1SUPERdoodle]

IS THAT STAINLESS PIPE YOU'RE USING

[@jamesglenn520]

Nope!! They are using Galvanized HVAC Ducting. It's the worst thing that people can use!! When they are talking about the Smell It's the Galvanized burning and gassing off and they are breathing it. It's VERY TOXIC ☠☠☠

[@joehallam1231]

Be careful of c02 build up in the room!...

[@BrianDunne]

Don't worry Joe..this was in an open vented greenhouse with a large vent above the outlet.

[@Anamericanhomestead]

PLANTS LOVE C02

[@mauriceoldis7541]

[@johnlbales2773]

+Joe Hallam Exactly right.

[@johndour5207]

Carbon monoxide is CO. Carbon dioxide is CO2. Flunk high school chemistry much?

[@paperwork1125]

Doesn't the top of the 55 gallon drum eventually burn out?

[@jamesglenn520]

About every 2 years if you use it all winter every day.

[@ethericomusicyourmind1360]

I'm confused. will the exhaust eventually lead outside? is this just a test run? is this his first rodeo and all according to his calculations rather than experience? I did that once, i mean how hard could it be right. Yeah, sorry guys, i thought i knew what i was doing.

[@josephhunt3452]

can i have a couple of dumb people pass me some bricks from over there? i feel for the brickman

[@feedingfrenzy4114]

are you telling me the heat riser was at 12 in?!?!?!?!?! they brought it down to 3in? jeezloufrikineaz. read more about it. universally 2 in is the rule from the heat riser/chimney and top of the barrel.

[@tspriggsabq]

+Feeding Frenzy Exactly. But God is on their side, they can do no wrong. lol.

[@BeControversialAlways]

What was the purpose of this?

[@judgeomega]

It burns more efficiently with less pollution. In traditional wood stoves you have a lot of loss out the chimney. In the rocket mass heater, the rocks and clay absorb virtually all the heat.

[@Intertanker]

I would suggest they have this heat plant outside of the house, and then use it for heating water, which again could be circulated in and out of the house. But that is also because I hate (for a while; short while, -;) ) the breathing of carbon monoxide.

[@TRIIGGAVELLI]

Where the fuck is this? Jonestown?

[@dagoflores979]

UnaSolida its a fuck i guess

[@Vikingshop]

I thought it was FORBIDDEN to use metal in the core of the rocket mass heater...?

[@ruffriffing247]

Lol let's burn all those paint with everyone...."you can smell it's not wood"

[@jamesglenn520]

People need to Stop using Galvanized HVAC DUCTING!!!!! The Galvanize is burning off and it is Very Toxic!!! Poison is what they are smelling ☠☠☠☠ Should be using Stovepipe or other Steel pipe. Plus the fact that the Galvanized HVAC Ducting is a tin with a heavy coating and when you burn it off you now have tinfoil. It's not an option for Long-term or a Healthy alternative!

[@DiemNguyen-nu8su]

1.25 minutes in...the guy in the red shirt says “have a couple of dumb people pass me some brick from over there”...

[@boa9535]

Diem Nguyen: Not dumb people. He said “young people.”

[@johnlbales2773]

"A common problem with some designs is "smoke-back", where smoke from the fire is released back into the interior rather than outside. Smoke-back could indicate a serious risk of carbon monoxide poisoning. This issue could be a result of poor individual stove design, or inadequate preheating of the exhaust tube, resulting in inefficient draft to pull the smoke through." from Wikipedia Rocket Mass Heater. Guys, please do your research. We do not want to have any sadness from this. Good luck. Be wise, not dead.

[@terrim5756]

John L Bales b

[@jamesglenn520]

The Toxic gassing off of the Galvanized HVAC Ducting is more of a concern than a little wood smoke!!! And almost every build you see Uneducated people trying to save a few bucks use it. Buy Stovepipe it won't Poison you and won't burnout as fast!!

oh ok . sorry I got it wrong. "young people" is what you said. Not dumb people. Got it.

[@GingerLeeH]

I thought I heard that, too!

[@bertdavis7456]

My first question is, Why was the chubby Dude in the corner blocking the top of the exhaust chimney. Some might say He was monitoring the temperature, but a couple fingers would do that. He was trying to block the flue flow. Then the biggest question is, We are not venting the smoke out of the greenhouse ??? The construction was weak but I don't think any of these people burn wood for heat. Why have a chimney at all if We can just let the smoke fill the room ??? Again, What was the Fat guy doing covering the chimney with His hand ?

[@blurryflag6466]

+Bert Davis clearly a saboteur

[@laurencerilling5873]

Smoke is unburned. Rocket stoves burn, so no smoke. Fat boy was feeling the exhaust.

[@bertdavis7456]

I guess I should have said EXHAUST instead of smoke. The issue is not whether the Rocket Stove is completely burned or not. The issue is that the Exhaust even from a Perfect Rocket Stove, is NOT Safe to Breath. The Exhaust must not fill the room.

[@carolsloanes4938]

What did he say " Can I have a couple of dumb people pass me some bricks over there". Now I know why the hat, to cover up his big head.

[@prodigyplayer]

wow, new guys... don't even know how to lay good brick and mortar. holy shit.. i'd be scared to grill with these guys on a propane coleman

[@hebekiah3623]

It's temporary, not even a solid base. Meant to be done in a few hours as demonstration.

[@aspitofmud6257]

The draft improved greatly when that guy removed his hand from blocking the end of the chimney. Idiot is as idiot does.

[@hebekiah3623]

I've had guys on job sites like him; think they are being useful if they stick their whole hand over it, like they're really really testing for you.

[@jamesglenn520]

It only started drafting properly when they shortened the barrel from 12inch to about 3 inches like it's supposed to be above the riser.

[@jaywatts8687]

do not build this way... did you see the bit of smoke still filling the room... can you say, C02, your dead. at least put the opening in frt of where you load the wood and put that opening (vent) at a 45* angle pointed down to prevent the smoke from raising. and where you load your wood make it higher and make a lid to cover to help prevent smoke (C02) from raising and filling the room..

[@hebekiah3623]

that's why they put the fat guy next to exhaust; when he falls over they vent the room.

[@chickenlips8696]

If you run up and back the bench and put the chimney riser touching the barrel, it will re-heat the gasses before leaving the building and increase the suction "draft" 5 fold. But you must insulate between the chimney and where it leaves the building.
