I don't know much about RMH's, so maybe all I need to do is watch a video to answer some of my questions.
I'm trying to plan the construction of a tow-able, off-grid tiny home, which I think will eventually end up somewhere in New England. I cook basically every meal (so a stove is essential) and get cold relatively easy.
I'm wondering if there are any DIY or relatively inexpensive RMH design's out there that combine a RMH with a stove and oven, that is also lightweight.
No. We have talked to the EPA about whether or not our stove is safe enough to use indoors and they said no. If you do use the Plancha indoors, proper ventilation prior to use, during use, and after is required. Our stoves are not UL rated, the Plancha model should be used at your own risk indoors.
Can my stove be used as a heater?
We do not recommend our stoves for heating. They were designed to be used outdoors and because they are fully insulated they will not transfer heat effectively, unless you are able to make your own heat exchange adapter."
I'm not sure if this is just the EPA over-regulating or if by proper ventilation they simply mean having the chimney lead to the outside of the structure? Any reason why this would be? Also any idea on how I could make a heat exchange adapter for one of these?
Both the zoom plancha and the Bear River stoves are designed for cooking only, not heating, and would need major shielding, floor protection, and insulated chimneys to use indoors.
What you would want for heating and cooking would be a J-tube style rocket heater, which would still need surrounding mass and/or insulation to allow safe clearances, but would be inherently safer to use since the woodfeed is vertical, and if you use wood that is not longer than the feed tube depth it can't fall out, and sparks are much less likely to travel in dangerous directions. You would need some mass, a couple of hundred pounds minimum, to make the sides and bottom safe for small clearances in a mobile dwelling and to store enough heat to keep the space from immediately getting cold when the fire goes out. It would be possible to make some of that mass with water tanks (unsealed so pressure cannot build up) set around or next to the core. These could be drained for travel to save weight, and refilled at the next stop (assuming water is available). A small RMH could have a one- or two-pot cooktop, convertible to an oven by putting a cover over it.
sounds like you need a gammera, its a heater and a stove, but there is little to zero mass. the inventor used my idea to make an available attachment that is basically a charcoal BBQ lid to create a removable bell-top-oven attachment.
John-- do you know where I might be able to buy one of these and how much they are? Not sure this is the best idea for me though, I tend to need a bigger cooking surface. Maybe I could improvise a better top.

Thanks Glenn-- Maybe it would just be best to go with a convential wood stove. What do you think about this Gamera John posted?

My first question about the Gamera would be, what is shipping from Bulgaria going to cost?
It looks like the combustion zone may be refractory lined, so possibly durable enough.
I doubt a regular woodstove is going to work very well or be safe. I think a purpose-built stove for small spaces (e.g. Kimberly, which is expensive) would be necessary. A rocket stove/heater could be great, but you would probably need to do considerable research and development to get there. It would be a good thing for the world if someone did it, and if you do try something, please fill us in on the process and results.
Oh, sure, you could do that. Or you could eat some pie. While reading this tiny ad:
