I'm about a week away from beginning my build and I've put a huge amount of thought and planing into it, and yet I still haven't got a plan for a heater, yet I do have an idea. My father was a teacher for a good long time and he taught in a building that had radiant floor heating and I was wondering if anyone had any suggestions for a Rocket Stove that instead of heating benches, heats the floor.
What type of insulation would I use beside clay, since it needs to be lightweight. I was thinking of metal dryer coil hose for the mass snake, but I'm not sure about what to put under and around it, and if I should use 3/8 plywood for the sub-floor with another flooring material over it. Anyone got any suggestions.
My first thought is to use the rocket stove to heat water which will travel thru the floor in a loop.
See the radiator that Bigelow Brooks Farm has on you tube in his greenhouse. or maybe a copper coil around the flue which will circulate under the floor, above the insulation.
My other questions are where are you planning to put the stove? inside or outside?
If you can please put some pics here so we have an idea of how you are doing.
I played around with the idea of some how getting a rocket mass heater into or under my tiny house. I am just finishing it up right now, moving into it next week! I am going to heat with an Alaskan wall tent wood stove. I have already had it up and running and it is surprisingly ideal for the 200sq ft house. I was expecting it to be way to much heat, but if I dampen it down it keeps the place toasty warm and burns through the night.
My plan for a rocket mass stove would be to put skirting on your tiny home much like on trailers or mobile homes in parks. But instead of just flimsy steel, I would use some 3/4 inch plywood and glue or screw 2" high density foam to the inside. Completely seal the undercarriage of the house. This is what we did with my dads cabin when he converted to geothermal.
Side story- Geothermal takes the warm air and circulates it under the house in the crawl space and the heat rises up through the house. This works very well and very efficiently, but the key to this working is an R-30 insulation value in the walls and under the house. Obviously for a rocket stove you do not need that much insulation because you have a mass heated.
As far as the mass, you could make it into pieces that could be broken down. either way if you plan on moving your tiny home often you def do not want to go this rout because the money in gas spent hauling around that weight would not make it worth it. I opted for something much more portable.
There is a video of paul and friends using bikes to tow a portable rocket mass heater, check that out if you have your heart set on doing it.
Would a solar air heater...the ones made with pop cans...work to heat under a tiny trailer house?
Obviously they will only send hot air under during the daytime and sunlight hours yet could there be some rock storage under the trailer,too?
Maybe set up two of these to blow under with heat being stored in the rocks.Also adequate skirting installed,too. Or would this produce too much moisture?
I'd enjoy hearing comments ,thoughts,suggestions for this is what I plan to do to help (I have a tiny woodstove to use as well) with the winter heating of my trailer house.
This idea could be easily portable.
All the best
Just Some General thoughts, Most Tiny Home Builders are not truly contemplating moving their final/forever homes EVER ! Many are putting wheels under
their Tiny houses as a Way to Escape the vision and legal arm of local Code Enforcement Officers C.E.O.s
As such, many people propose to modify lite tow-behind trailers and use the Feather-light Spindle-y axles found under those trailers to Escape said enforcement!
Often a lite weight trailer is acquired, and a trailer registration is purchased, and then the trailer sits in a side yard and depending on the new owners skill set
some kind of structure is created on top of the Trailer !
Often these Trailers -located in suitable climates- and provided with minimum amenities. i.e. Minimum heating cooling capacities and minimum water and sewer
storage capacities serve the basic needs of their owners well !
RV Insurance Brokers remind us that even the simplest pop-up type trailer being moved from one location to the next is experiencing the immediate equivalent
of simultaneous EarthQuakes and hurricane force winds during the trailers move, combine that with over-loading, poor tires, and axles, zero bearing maintenance,
and near total in-experience with operating a vehicle while towing a trailer, and disaster is a common outcome !
Short version- It has taken me 4 paragraphs to state why heavy-duty trailers should be considered FIRST when planning a tiny home on wheels build!
I have spent zero time dealing with heaters, Thermal mass, and such amenities as cooking and washing, room for storing possessions, and a minimum amount
on water/sewer storage, or hater heating!
The hardest part of learning to drive and tow a trailer behind your car is learning just how big your personal space has just become! And the single most important
part of that learning experience is in learning to L@@K -UP ^^^^^^^^^^!
For the Good of The Craft ! Big AL
