Rocket Mass Heater in a yurt

[wrdanner]

Has anyone here used a Rocket Mass Heater (Stove) inside their yurt? I'm looking to build a 30' yurt in the near future and it looks like it will require a serious heat source, bigger than I expected. I would think a Rocket Mass Heater would help by retaining heat in the dirt/other dense material after burning.

We're building our yurt attached to a shed/garage (which has the bathroom and laundry) so we're also considering traditional HVAC using gas heat but based on the things I'm seeing on the forum it sounds like it would require a large unit and would use lots of gas.

We're building in southern North Carolina, on the coast.
