Is it a possiblity to use a small RMH in a permanently set up 30-foot travel trailer. THe former owner took out all living room and bedroom furniture, so only the full kitchen still installed. even bathroom taken out (so I get to use humanure toilet!)
I know we'd need to strengthen the floor or as someone else may have suggested to remove floor and build a concrete support which would fit the opening and support the RMH.
We are going to be placing many inches of FREE~solid foam** under, over and around the trailer and it will be inside of a quonset style greenhouse, built from livestock panels. There is a hole in the wall where the refrigerator used to vent out, which might be able to be used for the exhaust.Are there already some threads discussing this which someone can direct me towards?
**Foam is the leftovers from a SIPS maker. 4-7 inches in depth R-4 per inch
The 1st thing we need to do is Get you a copy of ''The Book'', Ianto Evans' "Rocket Mass Heaters'', please go to rocketstoves.com to get your PDF Copy,
$15.oo! With over 100,000 R.M.H.s built around the world, most of them, and nearly all of the 1st builds (that worked) were made by people who used 'The Book'
There is STILL no other book in any language with more Rocket Mass Heater Family information. (and I don't make a dime)
It would be very useful to have a sketch or pictures of the inside dimensions. Does the Trailer still set on its own Tires and Axles, or have they been removed, how far
above the ground (or cement slab???)is the bottom of the Trailer? Travel Trailer is a kinda iffy term ! How old is it, how thick are the walls, ether measure at the doors,
or take an electrical switch box or wall plug box out of the wall so that you can measure the wall thickness, this will give us an Idea for the structural integrity of your
I am afraid that any attempt to cut a hole in the floor of your trailer so that you can then do a cement pour to set your R.M.H. and 3 tons of Thermal Mass Bench on, will
result in truly tying the Trailer Very Permanently to its present location forever, Going under the trailer to brace up the floor may be possible, but then you will also need
to re-inforce the load bearing surface of your floor with 3/4 plywood or particle board sealed against any spills, and then you will still have to have an air gap and a radiant
heat barrier between your floor and the insulated but still very hot bottom off the R.M.H.
Two more quick things, I am proposing that the only two possible R.M.H.s right for such a small space are a Commercial 4'' , or a D.I.Y.6'', please go to the Rocket stove Forum and click on ''Two more working rocket mass heaters - - - ! I assisted on the 1st build and Basically I want you to see in how tight a space we were able to create
a R.M.H., And a Thermal Mass Bench, This was an 8'', and the main part of the Bench is only a little smaller than a Twin bed, you will need walk-around spacing so only
you can tell if you will have room for a double bed !
I also want to send you to ernieanderica.info to look at their Bonny Convection Bench model which is 8 '' but you can adapt this to a 6''! Take the time to check out the
whole Web site as there are lots of gems of useful information There ! I hope this helps and is timely ! For the good of the Craft / Permies !

Hi Big Al,
thank you for all this information and the good questions to ask. I am only intermittently online, so it will take me a while to get through all you shared. some friends have THE BOOK and are much more technically inclined to build one for their tiny house.
