Hey all,
I discovered rocket stoves only yesterday, so I naturally stayed up till 2 in the morning watching videos. I found this [youtube]rocket stove Hot Tub pt.3 test firing: http://youtu.be/wHeegB1PMfA[/youtube] video intriguing - it's a rocket stove heated hot tub.
There's actually a series of 4 videos (I recommend them all), but what I wanted to ask you guys about was his design. I'm still learning (obviously), but a few things struck me as odd.
  • There entirely no insulation around the main chamber.
  • the water pipe run right down the main chamber, which i understand would impact the burn efficiency


  • Overall, I thought it was awesome, and I was really impressed with the guys creativity and craftsmanship, but wanted to get some expert opinions on his design.

    Cheers all!

    Thank you for your brilliant insight into the design.

    Mike M. : Unfortunately Max is all too Correct here ! The original rocket mass heater designs from the mid 1970s easily produced temperatures above
    2000dF, well above the temperature where we have Metal Embrittlement.

    With todays even more efficient RMHs with highly refectory ceramic materials surrounding its combustion core Temperatures are climbing even higher,
    and every burn reaches its steady-state high efficiency sooner with even cleaner burns, without sacrificing anything to longevity

    You- tube is hungry for content! And their attitude is if some one will shoot a video, u-tube will play it ! There is no peer review, no one to appeal to about
    flagrant violations of simple, basic safety guides !

    In short, There is a lot of CRAP on you tube! Let the viewer beware !

    There are some simple basic rules of physics that makes RMH work, and it can be easily understood, and safely made by any one with a 5th grade
    education !

    If you decide to follow up with rockets after this Rocky Start! And we all started green once ! even myself, even Max! Then Please Consider Going to ::-->

    Rocketstoves.com to Download a PDF Copy of Rocket Mass Heaters, this is the bible by which you quickly learn how to come to these pages
    to exchange ideas using the same basic terms to describe the sizes, shapes, And orientation of the RMHs parts to themselves and each other! Big AL

    Thanks Allen- I've definitely learned a lot over the past few days, and now see what you guys are talking about. I think I like the idea of what he was doing and particularly like his water manifold system, but I'm not sure it was actually a rocket stove by the time he was done with it.

    Thanks for the link - that's precisely the sort of document I've been looking for.

    Mike

    Mike McM. : A couple of things to help bring you up to speed! First came the Rocket Cook Stove which was created ~45 years ago~ as a needed replacement
    for outdoor 3-rock cooking fires that are closely linked to 750.000 word wide deaths of children 5 and under, and the 1/2 million children of the same age who
    become permanently blind as a result of exposure to wood smoke a powerful Oxidizer of skin, mucus membranes, and retinal tissues !

    Most All of these children could be saved from blindness with 5 cents worth of Vitamin A eye drops month -or- the simple adoption of the clean burning Rocket
    stove that burns a fraction of the wood that is used up in 3-rock cooking fires ! with a major drop in deaths of pre 5 yr old children ! This type of 'stove' is loved
    by Preppers, Zombie Hunters, and Survivalists, and generally is made of tin cans with loose fill dirt for insulation !

    When you have a chance to study the rocket mass heater Document you will see that the pocket rocket came next, a ''for outdoor use'' heater loved by people
    on picket lines and ice fishers, it burns very hot and cleanly, but, with no heat storage -you are cold as soon as the fire goes out !

    Next came the rocket mass heater with the adaptation of a vertically loaded self feeder, and meant for indoor radiant space heating! The incredible draft created
    by the adaptation of a Heat Riser made it possible to push the hot exhaust gases 50 ' horizontally through the Thermal Mass of an 8'' RMH system !

    Hopefully this will make distinguishing the various Rockets, by type much easier, and easier still as you read " The Book" ! For the Good of the craft! Big AL
