How about putting one under a trailer?

Here is the situation:
30 ft house trailer.
Approx 3.5 feet above ground.
Metal skirting anchored into ground.
Skirting insulated inside.
About an hour north of St Louis Mo.

Thought about placing mass near the center lengthwise.
Making a door in skirting to access the mouth of stove.
2nd flap door at clean out location.
3rd hole opening for exhaust flue.

Have some asbestos board I can shield right above the burn chamber.

I have been studying a copy of "Rocket Mass Heaters" but I thought I ought to get some feedback from the 'pros" here before I proceed.

Soil here is very pebbly river bottom stuff. Can I use it as my thermal mass (cob?) ?

Is your floor insulated? Are we talking a true travel trailer or a single-wide mobile home? Many have talked about cutting a hole in the floor of a single wide for the barrel and feed tube, then run the exhaust under the floor. Obviously not an option for a travel trailer.

Carbon Monoxide poisoning is a real concern with pebble mass, you will want to make 110% sure the exhaust has zero leaks.

Mitch Graves : You can read my response to Gail Moore, The R.M.H. was designed exactly for such small spaces as this, however to be the happy owner of a 'Rocket'
you must be prepared to give it Pride of Place, Because the R.M.H. needs frequent feedings of very dry, finely split wood, to allow it to burn at the High Temperatures
and great efficiencies that the rocket is known for. It needs to be in a central location where its proud owner can keep an eye ear on it to monitor its condition and the
magnetic Temperature gauge on the outside of the barrel, after frequent feedings over approximately 1 hour, your Burn Tunnel should be glowing red hot and you
can then fill your feed tube with 3-5 chunks of well seasoned (cut in 2011 for burning in 2013) Chunks of wood. Then as the home owner goes about his or her duties
over the next 6-8 hr period, the R.M.H. gets hands on attention approximately every hr, and produces both prompt heat radiating off of the barrel, and the larger
amounts of heat stored within the Thermal Mass which will continue to heat your house over the next 20-25 Hours, Building an R.M.H. under your trailer would only
work well if that was going to be your living space so that it is a easy chore to keep feeding the Dragon that resides inside every R.M.H.!

With the R.M.H. at a remote location, under your trailer you still need to have your thermal mass located within the trailer, so after you reinforce the floor you still
need to have a hole in the floor, and the weight of the Thermal Bench nearly 3 tons as part of the weight is now under the Trailer. You also need to plan on an Exit
chimney that will rise vertically to a height approximately 31/2 to 4' taller than the highest point of the trailers roof !

If we try and run a R.M.H. from a distant location we will have no visual or audible prompts to tell us that we need to add a chunk or two of wood, In Six hours of
running the stove we have lost about 1/2 of the 1st hour monitoring the 'rocket' and not doing any of the other chores a home needs, and then over the next 5 -7 hours
of time, you will be spending a large part of the time dressing for the weather, checking the R.M.H., waiting for the right time to re-fuel your R.M.H., Actually feeding your
'Rocket' and then shedding winter wear, so that the stay at home partner can get the rest of his or her work done, Believe me when I say that you will find that the 6 - 8
hours tending your 'Rocket' everyday will soon grow to a hated chore, instead of a gift freely given as a mere part of the days little tasks while the stay at home partner
covers That Days 6-8 hrs, I hope this helps you in deciding if a Rocket Stove is a good match for you in your location ! For the Good of the Craft !

Think like fire, flow like a gas, Don't be the Marshmallow ! As always comments/questions are solicited and welcome ! PYRO - Magically BIG AL !

You mean like a hypocaust in Ancient Rome? Then you have to do what civilized people have done for thousands of years and get the heat, but not the smoke to go up into the building trailer.
Sometimes you feel like a nut. Sometimes you feel like a tiny ad.
