Sizing a wood stove for a 20' yurt ?

[chrisdag]

Apologies if I missed an old post; tried a quick search with no results.

I'm in the process of planning for a 20-foot insulated yurt from

White Mountain Yurts

in NH and am looking for practical advice on sizing a wood stove to keep it comfortable in Western Maine. We are in the Bethel area near Sunday River and close to the ME/NH border.

If I just go by square footage I've got a smaller selection of wood stoves, all of which take 16 inch logs which are smaller than the 18 inch firewood we already have stacked to warm our cabin.

Does anyone have any advice or even BTU output range selections for picking a wood stove that would be powerful yet not overkill?

I'm looking at:

• Quadra-Fire Yosemite Yosemite Wood Stove
  
• Vermont Castings Intrepid II Intrepid II Wood Burning Stoves by Vermont Castings
  
• Vermont Castings Aspen Aspen Wood Burning Stoves by Vermont Castings

By square footage alone the 18,000 BTU Vermont Aspen stove is the smallest and most suited. I've never seen a stove that small though in online yurt pictures so I'm wondering if it may be undersized. The other Vermont Castings is specced at 27,000 BTU and the Quadra-Fire Yosemite is at 42,500 BTU

Thanks!
