Who is the resident wood stove expert here? I'm looking to get a super high efficiency wood stove that I can also heat a large pot of water/melt snow on. It only needs to heat 480 sq feet of living space, so no need for a large stove. This is the second issue. It will need to be transported by helicopter. Maybe I don't need a high efficiency stove, but my interest in those is due to wanting to use the least amount of wood possible.
