Sizing a wood stove for a 30' yurt on a 3' pony wall

[pmag]

Hi forum! We are putting up our 32 year old 30' foot Pacific Yurt on a platofom with a 3' pony wall. We are deep in a cedar forest about 100" from a cliff overlooking the Strait of Juan de Fuca in drippy coastal Western Washington. The placement is out of the wind but also retains the morning cold. We are trying to figure out how big a wood stove we need to get. The Yurt is for use as a movement salle, a place for seminars, etc.. but not a lived in yurt. Thank you! P
