Rocket Stoves

Besides being functional it is a work of art!  

Congrats on version #5!
Is there a version #6 floating about your head?

Hello Thomas and fellow Permies enthusiasts!  

Greetings from the Canadian PNW. We are currently enduring a 10 day run of cold liquid sunshine that has us trying to avoid early sunsets and soggy outerwear during our winter solstice!  

Yes and Thank you! Yes! There will be a Frankenstove Mark 6!!! Soon to be built and this time it will be documented online in a step by step series from the “ground up” so to speak…… it will take every thing I have learned from the “Frankenstove Franchise featuring what I have done wrong on previous builds and how they got resolved in “Frankenstove Mark 6”
However, Frankenstove 6 will be a unique build for a 8’ x 12’ greenhouse over an aquaponic fish pond for growing lettuce and other greens year around!!! Yes! Another ambitious project that I wish to share!
This will include a sizable increase of thermal mass to help regulate the temperature during late fall to early spring. It will be wood pellet fueled as all other Frankenstoves and be of a 3-4 inch ceramic tube riser. You will have to follow along for other modifications that may be interesting for those that may wish to build their own. I hope to keep tooling down to a drill, a grinder and a flux core welder to keep the build feasible with respect to fabrication cost. I also promise to pull out one of my older builds to “recycle and reincarnate them” keeping the spirit of continuous improvement with Frankenstove modifications like its iconic movie namesake!  
It’s good to be back on forum! Stay tuned!

Hello Peter,
I'm writing for just one reason: I want a small rmh for a small space - about 300 square feet. Whenever I look at rmh designs, they are gigantic. Yours is small. Maybe you or someone here can advise me: can I build a small rmh? Do you know? (I'd rather not be as high-tech as your designs, if possible.)

Shodo,

In theory you could build 100mm/4" BBR system. The ISA for such a heater would be around 2.4 m2, so the heater could be 30x30x55". However the small systems, with riser diameter less than 5" may not always work as desired. They are more demanding in workmanship and material selection.

Thankss, Cristobal. It's  a start. I probably shouldn't do the "more demanding" version, but 30" is very small so I can go a little bigger.
