We live in an old house with a quasi-finished basement and I am trying to figure out how to support the floor in the living room where I'd like to put the RMH so the floor will hold it. I was thinking of using those metal pillars under the part of the floor where we would put the RMH. I forgot what those pillars are called exactly. Is that what you used?
David Huang wrote: I believe those "pillars" you are talking about are called floor jacks, but I'm not certain. I thought I'd have to use them under my trailer for my RMH, but in the end my crawl space was so short it was really a wiggle space and I was able to use cinder blocks, scrap wood, and some wedges.

Have you considered using a bell (stratification chamber) instead of a piped mass? Weight is much less.
In my opinion, a bell loses its heat slightly faster than a solid mass but in an insulated home only on the coldest days might you notice.

I look forward to seeing how Calcifer progresses and performs! I have thought that perhaps a stratification chamber should be something for me to try too. My problem is that my trailer, and the room configuration, is too small to allow me enough traditional heat exchange bench length to fully draw the heat off before sending out the chimney. Thus mine is of rather "poor" efficiency for a RMH. I "only" cut my wood use 50 to 55 percent and my propane use 80 to 90 percent. :) It would be nice to lower my wood use even more. In my dream world I'd get below half a cord for a winter. Right now I expect to be between 1 and 1.5 cords.

Please document your build with pictures as you go.
That will help other first timers feel confident about building their own.
Feel free to ask us for help as well ... we have a cheerful crew of rocket scientists eagerly awaiting your questions!

My girlfriend and I are living in a 12x28' shome (shed home) over in Copemish and are considering different wood heating options.
Also, Howl's Moving Castle is one if our favorite movies and I am currently in the third book. We just took in a couple stray kitties in October and our son named the orange and white one Calcifer.
Anyways, let me know if i can help or if you are interested in meeting up at all.
Gerry Parent wrote:Hi Ryan, Sorry to hear your having problems. Was wondering if your batch rocket was built to the specs on Peters site Batchrocket.eu or it you just winged it?
Another bottleneck area is the top gap. Batch boxes require much more space than J tubes do. Off the top of my head I believe its a minimum of 12".
Gerry Parent wrote:That many cracks would definitely make a difference in performance. Even if you don't make any major changes this year and are able to make it work to keep you warm this winter, reading through Peters site is really educational and worth taking seriously as he has put a lot of time into experimenting and coming up with a solid system that works.
The batch box is much less forgiving than the J tube when it comes to dimensions and how to run it so that it produces a clean burn. They were never intended to run only single logs at a time, but rather (as the name states) in batch loads at a time.
