Paul, I would like to put a rocket mass heater in a berm ed 16 foot dome:
1) there are not any windows in the dome. It has a door and It has 4 air vents, 2 in and 2 out. Is there enough ventilation?
2) I would prefer to build it out of wood instead of cob, but would like to know if it will retain it's heat as long using wood.
3) I would also like to run my hot water (copper) pipe thru the bench, IF, that would heat the water enough to have warm/or hot water.
4) Would it heat a 16' dome that is berm ed?
I would really love your input as I am an avid follower of the techniques of the rocket mass heater.
