RMH possible in starplate dome?

I'm building 5 guesthouses using the starplate dome hubs (icosahedron dome)

They are small cabins

Struts are 8'
Which the instructions say build a "dome" 12 feet wide , 11.5 high
And just 110 sq ft

Obviously the longest walls are 8'


I have the first roof going on and need to decide very quickly how I'm gonna heat these cabins since I'll have to leave room for a flu If  necessary (ferrocement roof)

I have a really thick earthen floor (3 feet) if that makes a difference

Should also add I live in Death Valley ... Although it's known as the hottest place in the world our winters get down to 20F in day and colder at night
But never to zero F.

I love RMH idea but is my dome too small? All the instructions I've seen, videos, photos they are all huge!



Thanks in advance

Your domes are quite small to heat with an RMH, but it should be doable if you are good at following directions and perhaps troubleshooting.

You would want the smallest feasible RMH, which for a standard J-tube design would be 4" internal system diameter. This size is known to be finicky, so I would test your construction before making it permanent. You could also build a slightly larger, and thus more reliable, version, 5" or 6" diameter, and just run shorter fires in it. Assuming the cold spells, and possibly occupancies, will be short durations, a smaller mass would be called for, as it will be more responsive to the firing schedule and warm up and cool down quicker than a massive system. I would not make shorter duct runs or smaller internal bell areas, but thinner masses that transmit heat faster.

Rad Ruelan, posted this so others know what you are talking about.

Just wondering how your starplate guest cabins turned out?  And was the Rmh a good fit for these?   I plan to build some myself, as it seems the fastest way to get a cheap and sturdy structure, esp if I use latexcreted fabric as the exterior shell.
