  1. Hang on, he said 5 experts in this field and then a bit later he declares
    the barrel doesn’t fit over the brick stack they had made! Umm, I don’t
    think that quite adds up, wonder how embarrassed the 5 experts were? Did 4
    all immediately point to just one and say ‘It was he/she’s fault” that
    would have been comedy gold.

  2. Even experts make mistakes,that is how first light bulbs were made ,from
    the mistakes ,it shows that each stove is individual if you want uniformity
    buy a wood burner and send 200 to 300 degrees centigrade straight up flue.
    flue temp on my rocket and 30ft pipe store after 6 hours firing is never
    above 60C

    [EDIT] I’m sorry… Not the cob… The insulator for the stove pipe.
    Perlite, clay, water, what ratios? Thanks.

  4. I have seen barrels burn through. Would fabricating a barrel with 5/8″
    steel be better? I plan on running one of these things non stop for 7
    months a year. Gets cold and stays that way for a long time in Northern

  5. @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.

    Last comment from poster was 11 months ago but thought I’d ask anyway… I
    checked the website but haven’t scoured any forums or anything, if I did,
    I’d just be asking there… What is the cob’s composition? How much perlite
    am I using to how much water and clay?

  7. 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…

  8. I noticed the barrel was still painted green, shouldn’t it be burned off
    first? That could produce some toxic fumes. I don’t know, just getting
    ready to build my first one.

  9. I think to get a really clear idea, you need to look at the drawings that
    are part of the rocket mass heater article at The chimney
    *IS* the heat riser. Everything after the heat riser is working with

  10. 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.

    @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…

  12. @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.

  13. 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?

  14. It is my understanding that Max temp for hot dip galvanized plating is
    480°F. If you can be assured your flue temps never get past that point at a
    certain point in the design, it would probably be relatively safe. Anywhere
    near the ‘rocket’ part of the stove should be verboten. You can use
    stainless steel assembly style flue pipe. It’s not too bad price wise and
    tougher than black pipe.

  15. 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.

  16. I was thinking about building a worm gear with a speed controller to feed
    wood pellets into one of these. Do you think that would work ok?

  17. 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 🙁

  18. Cool. I can’t wait to see this perfected and mass-produced. I don’t get how
    there’s no smoke. Of course, when the wood burns, smoke is produced, so is
    the smoke absorbed into to pipe liner or does some chemical reaction change
    the smoke into steam? Would the liner need to be replaced periodically or
    could it go on indefinitely?

  19. 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’…
