rocket stove mass heater workshop how to tutorial

[briangunn21]

what is cob

[paulwheaton12]

@briangunn21 a mixture of sand and clay. Sometimes a bit of straw too.

[VanGoghRothko]

i'd be using stainless steel for pipes not that cheap galvanized pipe

[josephdupont]

why can't you have the exhaust leave at ground level?

[VanGoghRothko]

@josephdupont you'd probably die of CO poisoning

[TripleJdrum]

Love these videos! Keep them comming.

[paulwheaton12]

we have discussed heating watter and russian stoves many times at permies.com

[nerblebun]

@paulwheaton12 This video is way too convoluted. It's all over the place. I thought it could teach me how to build a rocket stove mass heater. Now I don't even know what a rocket stove mass heater is...

[cudaclan]

This design reminds me of a mini Russian fireplace, minus the horizontal ducting and hearth design. If you continue to add multi-chambers vertically, alternating the flue left to right, it resembles the stove. Incorporate soapstone (seating area) with the thermal mass properties and you have an ideal low emission source of heat. Have you tried to integrate a hot water tank design for running water?

[ML424wr]

Galvanized ducting gives off zinc fumes, stay away.

[DickHBox]

@ML424wr Not at the temperatures involved downstream of the combustion chamber. When the flue-gases reach that point, they're below the critical level.

[muserwood]

Do you cover the cob with cement then? I wouldn't want to sit on just dried clay.

[eternalstarsurfer]

great channel



[thinkyourright]

There's nothing said about how big  a space this is going to heat. Nor do you say where the location is. Is it a very northern clime?

[Rhinoch8]

Where does this concept comes from? It is like super efficient and could be used everywhere to get self-sufficiency! The only problem is if it get known, to do something like making the energetic change, some kind of dork will try and patent it :(

[paulwheaton12]

@Rhinoch8 Ianto has a book on it. i have an article at richsoil dot com

[Rhinoch8]

@paulwheaton12 I'll check it out. Thanks for making people like me discover permaculture!

[eotto2001]

Have you had CO test run on this one?

[paulwheaton12]

@eotto2001 I have not. If you send me the tester, I will test it.

[eotto2001]

@paulwheaton12 -- Don't have access to one at the moment. I wasn't clear how it was being vented and if the combustion air was adequate to keep the CO levels to a minimum. When I first looked at the video it wasn't watched too carefully, so I thought the double wall pipe was a single wall which would have meant the exhaust was greater than the combustion air. I sent the video to a HVAC building inspector to get his opinion.

[draemalic]

Isn't using galvanized piping a bit dangerous?

[paulwheaton12]

@draemalic there are some issues - fully discussed in the forums at permies dot com

[thedirtygoat]

Enjoy watching the vids... Good to see people getting back to the real art of heating from wood... Go back and take a look at the way people would build stoves for heat and cooking long before we were here... You'll be surprised... It's kinda like the way nobody knows how to change a tire or oil in their car now days... Just sayin'...

[Rauschelesee]

Please can you help me. Whats are the name from this "rocket stove mass heater" in German? Thank`s Martin

[MrSafetymeeting]

I want to make a small version for a housebus. I don't think firebricks will work because of the movement. I was thinking of using something similar to what people cook on with a small barrel/riser setup on top. It would have a brick surround for thermal mass. Any thoughts or suggestions?

[paulwheaton12]

@MrSafetymeeting Have you been out to the forums at permies yet?

[quikjustin]

Where do i find women that are interested in this sort of thing?

[ouwetwarrior]

@quikjustin Iran LOOOOOL 

[NibiruMagick2012]

Great Information*****sub

THANK YOU

[brassel]

I love it when people are pioneering, improving, inventing by trial and error, themselves. Make a great idea better and work for you and involving us in the process.. I am not such a person:(, but it gives me inspiration. Thanks!

[TheWaggaBloke]

I live in Australia.. I'm having trouble finding some clay to build my Rocket Mass Heater for my Shed.. Can anybody help me with the problem? Please!!!. Rod

[definca]

Galvanized ducting is not rated for wood stove pipe. Plated pipe will give off toxic fumes when heated. It is the wrong product to use, even though everybody thinks it works great is is creating poison gas that is very unhealthy.

Ask any wood stove expert. use black pipe or blued pipe or stainless for high gas ducting not plated.

[billlyh]

@definca

FYI If you're talking about the pipe in this video, you need to look closer. It looks to me to be a piece of Triple Wall pipe that is used inside the house through the ceiling, or anywhere that the pipe has to be installed close to wood, or some other flamable material. Sure you're not supposed to use galvanized pipe for a burning heater, it puts of poision gases, like you said. You can die from welding galvanized, if you breathe enough of the smoke your welder is making.

[HostileHST]

@definca If it's going to a heat exchanger, it doesn't matter.

[EKWisner]

@definca Good point, galvanized is not appropriate for high-temperature applications, since the coatings break down at about 700-800F. We definitely do not recommend it as a substitute for stovepipe. However, within the earthen mass, the temperature of the ducts is only 500F at the hottest points and times, and generally much lower, under 200F, elsewhere. You will see that the form for the interior of the insulated heat riser is indeed black stovepipe, rated for much higher temperatures.

[MrStemkilla]

@definca that looks like galvinised insolated duckting that is ment for wood stove chimdys. but what they are dooing is simple pysics but the flame is going to be directly blown into the metal and i can definetly see it getting too hot and creating toxic gases. they also insolate it so it definetlu cant exspel its heat. and the steem comeing out just seems to me like the smoke is depositing all it carbin on the walls of the pipe ... a pipe they cant clean so it will buld up and stop working

[the1969info]

I really love your videos of the rocket stoves. Could you tell me why there is a drum over the vertical shaft instead of putting an elbow on the pipe bringing it back down to the pipe that heats the bench. Thank you

[paulwheaton12]

Check out the article at richsoil. There is an image there that shows how it all works that I think will help you to understand.

[kelltiozim]

I'll give ya five ***** because people need to become more self sufficient and less prissy. Cool.

[leighblackall]

I saw the lighting in the end :) Looks like it drew straight away! wow. really?

[leighblackall]

great job! Can you give me a video on how you light it? I suspect that it takes a while to draw, so I want to find out how users of these prevent smoke going into their room...
