rocket stove mass heater workshop how to tutorial

http://www.permies.com
I attended this workshop in February 2009. The primary instructor was Ianto Evans, author of "Rocket Mass Heaters: Superefficient Woodstoves YOU Can Build" other instructors included Ernie, Erica, Max and Kiko. Basically, this is a super efficient wood burning stove, with a cob bench bench thermal mass to hold the heat. One tiny fire can heat a room (and warm your butt) for a day! Please forgive that my camera is not the best, but I think I got the main information across. Lots of discussion about this sort of thing on the forums at http://www.permies.com

would you or anyone be able to do like a basic graphic or animation or just a drawing design of how the thing looks? nothing fancy just basic idea

i sort of understand it but think a design would really help me understand better, but i havent come across a good one just browsing and would love one from someone who has actually made one before

@dramey03 have you seen the full article at richsoil.com?

[briangunn21]

what is cob

[paulwheaton12]

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

[paulwheaton12]

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

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

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.

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

[Cayennem1st]

This is cool!

[dramey03]

@paulwheaton12 i have now thanks to your suggestion

appreciate it, great site

[dramey03]

also heres a question for you galvanized pipe haters

i have heard yes its toxic but i also heard once the coating is burned off in the initial heating, its safe after that

is that true or does galvanized stuff stay toxic no matter how many times its "burnt" off?

[tya04]

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?

[Av3rnus]

Can the mud be replaced with concrete for better appeal?

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