look around, there are a lot of people into this. There is a community out there that we were able to contact...(online community btw) that had plans that we were able to get. They were either free or really cheap. We adapted them to 10 inch stove pipe and full 55 gallon barrel. Used 2 times the amount of clay/mass too. Works.

Plans are perfect Vlad!

yeah only the narrator - he now says to do NOT use a metal heat riser

Now that you've had it in for a while, do you think that its better without installing pipe in the mass or with the pipe in the mass of the RMH?

Al Gore must get richer!

Why are you BUYING green energy things? Often the greenest thing you can do is repair, re-use or re-purpose something you already have, or has been thrown away by other people.

@@wiretamer5710 a good balance should be buying things and re using and repairing in equal balance to gain the strengths from working with both

@@copecotrain As long as Green energy companies are run for profit, and not to meet the needs of society you'll find that it's expensive; it has nothing to do with people fighting for a greener climate, like Al Gore, and everything to do with living in a Capitalist economy that is run for profit; as long as profit is considered a goal, solutions that people require will always be more expensive than they need to be, in order to generate that profit.

Would you work for free? I wouldn't expect anyone to, employees cost money so there has to be some way to pay people to work, as well as pay the bills too. Free-enterprise is the best way to keep greed under control, when businesses must compete for customers, it forces them to keep production costs at a minimum in order to maintain status. Socialism only works if an outside contributor is present. Talk to anyone from Cuba about how life was there.

Did you force the exhaust down towards the bottom of the burn chamber and then horizontal to heat the mass like a long bench and then to the outside with a long riser outside your house? Keyword "Mass heater"

If you looked at more videos of this, you would know that there are NO residual gases left to burn. They do not use metal in the main burn chamber. Why? Experiments show that after a few "burns" its all melted apart scrap metal.

@@johnverkler3962 Interesting reply, thank you ...

@@7ann7seven13 Thank You for your Thank You. =-)

Gas inside burns down instead of coating the pipe.pressure keeps it cleaner just ashes to clean

There are usually T cleanouts put in, but the stove also gets up to temperatures that combust virtually all material and volatiles. The mass takes the heat that usually gets to above 1500 deg. Safest and most efficient stoves in the world are also illegal. Hurrah america.

@@johnmarkhatfield very well said. "The- powers-that-be" (government and insurance) likely, do not, in their minds, like the idea of an un covered open flame in the room. They have the built-in unwillingness to change... anything. New ideas are out. Disclaimer: If the Rocket Mass Heater is not built exactly right, it won't operate properly, and could be dangerous. They do not understand the powerful down draft of the system won't let flames, poisonous gasses and smoke into the room. They're too used to the common metal, un-efficient wood burning heaters that let most of the heat fly up the chimney.

I watched your films, you did a good job

@Heinzkitz Velvet - that does look good. They seem to know what they are doing.

They've come a long way

Nobody cares of your explanation.its everywhere buddy

my question is ...how do you clean out the ash and soot , and how do you light the fire

"Wood doesn't burn it's the gases in the wood" The solid carbon that becomes charcoal isn't gas dude.

+macaristan34 Good point.

You design in a few clean outs. No problem.

If done right, there is no ash. Add enough oxygen and you will have complete combustion into water and carbon dioxide.

Good point. My Baba (who is now 99) used to do all these things on the Canadian prairies. She learned from her folks who came over from the Ukraine. My folks, however, have no clue. The knowledge transfer was stopped because people had figured that they had found better ways to do things. Facing limits, it appears we're rediscovering 'new' ways of doing things our ancestors used to do out of necessity.

Masonry heaters are traditional, rocket mass heaters are new. Of course, if your family invented them a hundred years ago, cool. But they were never general, or really known.

This is because americans beleive they are the only ones who invent everything..while in reality they are just the fattest uneducated people on earth!!if u can name all presidents you have culture for them 😂😂😂

NPC you sound like a fucking communist.

Its the internal shape of the rocket mass heater and te efficiency obtained that is different than Russian ceramic heaters.

+M Spanford Lighting a small piece of wood and holding it inside causes the warmer air to rise up the long vertical piece. This causes the pressure differential which creates that "sucking".

www.conicet.gov.ar/calefaccion-accesible-y-de-primer-nivel/ I have seen one of these stoves here (they call them the russian stove). And it suck the smoke inside it like a vacuum, making a noise like a motor (as shown in the video). Is very neat. No smoke, not ashes. But here they use a chimney to vent the stove, with very few smoke.

I have a rocket stove heating my cabin here in Alaska I used 1 cord of wood last winter. While my design is different, the concept is the same. Believe me, any flame at all under that chimney will start the process. Once heat starts to rise, the fire increases and draws more air. I have occasionally gotten some flame outside the firebox and it sucked it rite in. my cabin is 10x14., if there was even the slightest smoke being introduced into the room it would be horrible.

It mostly collects just where the pipe exits the barrel, the manifold area. Since it is 95% efficient, there is very little ash at all. But you can build a cleanout there, and in other places. Normally some kind of metal screw cap. The barrel normally can be removed, or some people use just enough of a second barrel that it can be clamped to the main barrel with a barrel connector, that gets you pretty much inside everything.

were can I get plaines

Please call the office for more information 585 889 2002 Thanks

I ended up pulling it apart and changed that gap from 2 inches to about 1 inch and that seemed to make all the difference

Time to make that idea into video... and if you do ? Please use some other then a boring ol’ barrel.... Good luck I’ll look for your video!

@@randalmoroski4423 The "boring old barrel" as you say, is what runs and makes the thing work.

The barrel does not need fins to make it more efficient. You need to watch more videos to see more of how they work and why they wouldn't need fins.

m.kzfaq.info/get/bejne/Zp2AYJmY1r_LYps.html actually i think he has good point. many of these DIY rocket stoves still produce a little smoke and some a lot of smoke. if you don't get the measurements for each chamber exact it won't burn as hot or as clean... i wouldn't build the link i showed but i bet a fan blade on a DIY rocket stove could make it more efficient, especially if your measurements were off..

I believe you can actually touch the barrel and not get burned. The gases that come out of these (properly made) units is less than 120°.

The insulation on the heat riser (inside pipe) is to keep the exhaust gasses as hot as possible for a more complete combustion. More complete combustion = more heat generated.

that's the point of having the barrel produce radiant heat. it gives the instant heat you want, very soon after you light the fire, easily comparable to a normal wood stove. the mass only collects heat that would otherwise be leaving the chimney. you cant do that on a normal wood stove because a normal stove doesn't get hot enough to burn the creosote before it can condense on the stovepipe. when the exhaust leaves the barrel, it is mostly nitrogen, CO2, and water vapor. this hot exhaust is pushed out through the mass by the force of the super heated fire in the heat riser. by the time it leaves the house, it is 100-200 degrees.

I've not built a rocket stove and am no expert, but I believe by design there's SIGNIFICANTLY less ash produced because of the method of burn. I've seen some designs that have ash traps and collection areas on the exhaust as well, so I think that's an option.

There are multiple clean out ports. One is at the bottom of the J tube (the bottom where the wood sits), the next is right next to the exit pipe on the bottom of the barrel so you can clean out the barrel, the others are placed along the stove pipe ducting that is surrounded in the cob mass. The easiest way to clean out the ash is using a vacuum such as a shop vac. There is very minimal ash build up due to such an efficent burn, and the ash that is loftover is a very fine powder.

not enough draft. Increase height of chimney? Decrease size/diameter of tube?

+Robin Sauls Google is your friend.

Well Brett-thanks for that. Nothing!

Well Mr. Sassy Pants, here's a direct link then. bfy.tw/4UtK

+Brett Williams ... Brilliant!

Brett, that is awesome, I did not know google had the feature. LOL

Yeah no one talks about the cleaning side of these things. It's probably a huge pain in the ass. I will try these when someone figures out an easy way to clean them.

the barrel cools off quickly when the fuel runs out , warming the large mass stores the heat that is released into the dwelling over many hours . instead of going right up the chimney like a conventional stove

Hi Michael, greetings from Colorado Springs Colorado. I'm extremely concerned that the "sustainable" push, generated by the *Green Movement is a trojan horse of dysfunction. * The people at the core of this have managed through propaganda to convince much of the public to accept ideas about energy and energy use that don't work. Have a great day. C H

@@christophersleight19 I don't know if this is an appropriate response to your statement but I believe that a large part of the climate change push is reactionary and more dedicated research is needed. I don't believe we have a full picture and that fear mongers are using it as a stick to beat any opposition to their rise to power. I would like to become more sefl-sufficient to first provide for my family and second be in a position to help others. My actions are independent to the green movement.

@@michaelrowley6069 , what you said, excellent. Thanks C

those cats sure know their RMS tech. I think they were the folks that helped my fam with plans a few years back.

Same question, he said the exhaust goes through the bench, but the architectural drawing showed a regular chimney???

Perhaps not shown, there should be a duct cap/ cleanout right where the gasses leave the drum. Ash will collect there, but really it burns so hot/ efficiently you may only get a double-handful of ash out in 3-4 weeks.

The ducting, carrying hot gasses, leaves the drum, travels through the mass/ bench, doubles back through the bench, then goes to the exhaust riser (what you think of as the chimney) to get the CO2 and water vapor exhaust out of the house.

Joram Dehens Yup. www.network54.com/Forum/417256/message/1259395233/Stirling+Engine+stovetop+wood+stove+fans

Free USA? That is just words! Even breathing costs us money here! Le alone living for free!!!!!😂😂😂🤨🤨😔😔

@@jamesw6484 thus the quotes around "free".

***** With any high efficiency furnace, you have a lot of condensation. Because there is moisture still remaining in the wood and from the combustion it's as a byproduct. You'll get condensate somewhere if the exhaust isn't over 212°f. As for your stove, any and all moisture produced is totally vaporized as it goes up the flue.

They say now to NOT use metal for the heat rise - so yes

It's been done by a few RMH builders, so yes.

Ernie and Erica Wisner have been making these for decades. They know what works, and what doesn't. They have a published book. I don't remember the exact name of it. Rocket Mass Heater is in the name.

Auto correct spelling is a punk, sometimes.

there are several iterations of rocket stoves some have outside air intakes . I have seen dozens of videos on rocket stove installations. The take away on air intakes, they need to be insulated and should have a good damper for control of the fire " very important" in case the fire has to be put out in a emergency. and a screen to keep critters out . If you have a very air tight dwelling you will certainly need out side air . and when the fire dies out, air needs to be turned off so out side air that comes in through cracks and crevices , and under doors wont be drawn so hard, cooling off the Dwelling , and the mass. The concept of the RMH is sound and if care is taken in design and construction. you will be rewarded with a system that is way greener than the old oil burner.one stove is indeed certified www.rocketheater.com/customer-reviews-and-special-thanks/

heat rising makes the fan blade spin and thus circulation happens .. heating the room :)

Yes. There is a thermocouple between the upper fins and the base.

The grey clay was a 'clay and sand mix', not cement. They did not wear gloves because the mix poses no hazard. You can buy industrial/commercial grade clays, just Google 'Clay Suppliers'. 1000kg, a metric Ton, costs around £220.

ok! good to clear that one up ;)

It's called cob. look it up for various mixtures primarily clay , sand , soil, and some add vermiculite .

Public Relations probably. They actually support quite a few green energy initiatives.

Barry Jordan - in this case they are probably targeting marketing to those looking for info on home heating.

Because Shell. Sell a lot oil in those clunky Ol’ barrels.... 🤣

good in gardens, or fields. Very similar to pot ash or limestone that is used to help make your earth a little more basic. To clean it we use a extra long shop vac hose... makes the hole stove whistle...kinda cool.

I'm sure they will condensate and rust

IXL Masonry or Brock White. IXLs are more expensive but less brittle.

most of the ash is in the burn chute. and can be scooped out before each fire . the fire burns much hotter than a regular wood stove as it enters the burn chamber and burns hot enough to vaporize creosote . not much is left .except gasses

It basically "works" because it dumps its heat energy when it comes out of the inner flue and encounters the 55-gal drum. Not only does it "dump" its heat energy, but the (realtively) cooled air sinks, drawing the hot combustion air upwards. If you insulate the drum...you lose the draft. Ideally, you should insulate the inner flue, so that no heat is transferred to the gas in the 55 gal drum portion...I don't see them doing that here.

Existing wood stoves may claim to be 80% efficient, but they are just 80% MORE efficient than the last piece of junk ineffecient wood stove. Not 80% out of 100%.

Darrell Jacob JR - close... Actually, they are 80% efficient at combusting completely and turning the fuel's available hydrocarbons into heat... The fact that they send a huge portion of this heat out the chimney as 500+F exhaust to maintain stack effect has no bearing on the "efficiency" rating. It is in no way claiming that 80% of the embodied energy in that fuel before burning will wind up inside one's home. That (highly important to real world value) factor is not a part of the EPA wood stove "efficiency rating" program. It's all about cleanliness of combustion, and the rocket design has them beat on all fronts right up front in the super efficient primary and secondary combustion it creates. Well designed/built Rocket mass heaters create 90-95+% combustion efficiency for most of their burn cycle, AND scavenge most of the heat from the (MUCH) cleaner exhaust gasses, before sending them out of the building... And have a "real world efficiency rating" that is probably closer to 80%, wheras the "80% efficient" (at combusting the wood) stove in my living room probably has a real world efficiency (net energy from the wood burned kept inside the home) of closer to 20-30% I clarify this mainly for others as I know from other comments that you have an intimate knowledge of RMH's and their construction/design principles. I just wanted to explain the facts for people used to using normal wood stoves and talking about their "efficiency ratings", who have not experienced the real world difference between the two... Which stated simply is: A properly designed and homebuilt Rocket Mass Heater, burned a few hours a day, will keep you warm (70+F) 24/7, on anywhere from 1/4 to 1/10th the wood of a "high efficiency rating" modern wood stove.

bcubed72 - the dumping of heat energy at the barrel is the second half of a two stage thermosiphon... The first stage is the rocket's highly insulated burn tunnel and riser tube. At 3000+F in the most highly optimized designs, that 3-4 foot burn tube creates MUCH more stack effect than a normal chimney of that length due to the huge temperature differential... The barrel then shrinks these gasses back down to flow through the exhaust at only somewhat higher temp and velocity than the intake air being sucked past the fuel.

Actually, it's still 400ish*F coming out of the barrell...it's the mass that sucks the heat out to bring it down around 100*F.

+motherchucka1 is there a link to a iron stove set up as you mentioned and is it still a rocket stove?

+motherchucka1 You are missing the point of the thermal mass which retains and slowly releases the heat. Steel cools down really fast. Anyway it should be clay, not cement, holding the fire bricks "apart," not "together".

You design in a few clean outs.

Trash incinerators using a fluidized bed burns at 1700 plus degrees most generate steam which drive a turbine for electric generation . many maintenance issues from acids in metals , and plastics you would have those problems as well. there are safe guards on commercial applications that a simple rocket style stove wouldn't have. Not recommended .

seasoned does work the best, but a 50/50 blend on the not super cold days works pretty good too. 1/2 dry, 1/2 not dry. Not sure about green though, that is really wet stuff. Small pieces yes...but you can use a lot of stuff other than wood. Some people make paper pellets from all their old paper, others use brush, and corn stalks...I seen someone was using horse dung (dried of course)...I cannot imagine actually using it for in your home, but if I am cold enough...lol.

Same materials yes same design no. The research institute perfected to obtain the higher efficiency. The Insititute didnt invent wood stoves for heating with mass but they made one of the best ones we know.

Very carefully... they typically burn VERY hot... far hotter than necessary for cooking.

Ob Fuscated well said and well thought out
