Sarah Yao :
- As always, have you been to WWW.rocketstoves.com to download your pdf copy $15.
oo, of I. Evans' book '
Rocket Mass Heaters' ?
Assuming that your Mfg'd home sets on cinderblocks on a
concrete slab (?) -Someone will have to go in under your structure and cut out all of the material out from under the floor
where you are trying to set the foot print of your R.S.M.Heater ! This will include the vapor barriers and the Insulation! At that point they can start work on re-routing Electrical and
Water lines ,
Plus the Ductwork of the existing Furnace/ Heating plant.
All this work is prep for the welding work that will need to be done to brace the Frame that Supports the floor and all the rest of your House, so this work will have to be done by some
one with experience with Mfg'd Home Frames, Electrical, Plumbing, and H.V.A.C. Experience, then comes the Welding / Bracing work ,and replacing every thing back the way it was before, Then you
can start on the changes to The Interior of your home !
Inside you will have to reinforce the floor with 5/8'' or 3/4'' plywood, set bricks/pavers down in a pattern to make channels for air flow under your Thermal Mass, then your
1st base layer followed by a layer of reflective aluminum foil material to reduce heat radiating down through your wooden floor, then you can build your R.S.M. Heater on top of that frame !
Google "
Rocket Stove Instructional DVD'' and play the clip from Kickstarter, at 9-13 sec you will see the air channels under the bench, and at 23 sec you will see the exhaust channels
at the top of the benches, this is the gap that you will need to have at the floor and the wall behind the
Rocket Stove/Thermal Bench ! I have signed up to this 'Kickstarter' drive to get a copy of
this DVD for a Future build !
Having accomplished all of the above, I would not guarantee that your Rocket Stove would heat all of the farther ends of your trailer !
I am putting this out here not to dissuade you from building a Rocket stove but to make sure you have a few more facts before you outlay much for materials for a
project that would
stop a good general contractor !
Be safe, Keep warm, Pyro-magicly yours Allen L.
