I have a 30' yurt up in the Adirondacks and while taking with a relative of mine about how I hadn't got a wood stove for it yet, he actually gave me an old one he had in a shed at his camp.. It is a Lange 6302A and you can see the specs here if you put in the model # etc: http://www.woodmanspartsplus.com/catalog.aspx?ct_id=68 Anyway, I am pretty sure this stove is more than enough to heat the yurt, but then again I have very little knowledge in this area. My yurt has reflective insulation just like most yurts have which is great for reflecting radiant heat but when you break it all down, it is still a really large tent. Here is a pic of the insulation while we were building it: Anyway, in the manual it says it can heat 7,000 to 9,000 cubic feet. Is there any way to convert this # to BTU's? The yurt manual says you probably need a stove that can push out at least 40,000 BTU's. Thoughts?
