greenhouse construction + rocket mass heater how to tutorial

Greenhouse construction with a rocket mas heater, including an excellent demonstration of the rocket mass heater sideways burn. The greenhouse construction class is taught by Ernie and Erica Wisner, featuring the rocket mass heater techniques of Ianto Evans (of cob cottage company fame). I cannot think of a better approach to greenhouse heating.

This is the first phase of building this greenhouse. The focus is on the steps of building the rocket mass heater.

This video has an excellent demonstration of the sideways burn - or fire burning sideways.

Since this will be an oehler style solar greenhouse, then it probably won't need much heat. But it will be a bonus. And the heated air could also be piped into the house.

A rockey mass heater is typically 10 times more efficient than a regular wood stove. And 20 times cleaner.

A mike oehler style greenhouse construction is probably the most efficient greenhouse known.

Hi Paul! Thanks for the great videos all around! At the end of this video you make reference to filling the trench back in with soil. In your professional opinion, what would be the best way to insulate the duct running through the ground? Should the trench be prepared in any way or even insulated at all?

[paulwheaton12]

The duct should never be insulated - that would be the opposite of what we want.

Won't a large huglekultur bed do a similar thing as far as warming the soil?

[paulwheaton12]

Nope! However, good texture to the landscape could give you warm pockets outdoors.

Is there a golden rule on how long you can make the horisontal tubes. and still get draft enough to pull out the smoke/steam?

[paulwheaton12]

It will depend on how hot you can get your heat riser.

[ribin21]

its been 2 years since this was installed is there a report on its pros and cons

[paulwheaton12]

Go ahead, make that better video.

Ever seen someone blow a smoke ring? Thats a torus

These things work because of the temerature differential between the very expanded gasses created by the supe hot spiral fire and the heat taken out of the exhaust duct via the thermal mass causes those gasses to shrink enormosly in volume as it cools... this action creates a vacuum which pulls the fire sideways and makes it super hot which helps to burn the creosote and volitile gasses from the wood fire... pretty genius stuff

more of a demonstration than tutorial. how to's usually fully explain how to build something.. 

[mariposasign]

too bad your sound messed up at the end, but i am going to make one -thanks for the video

[ddreamsky]

This SO backs me up when I showed my husband. I want a greenhouse that won't cost us more to operate then just buy the food. Thanks!

Did you ever document the building of the greenhouse? Looks like it was gonna be a pretty sweet setup

[xerr0n]

from the ground... or from the shops that sell clay (hardware store etc) hope it helps
