I’ve got a coal burning smokestack so next winter I’ll do my best to help you out.
I have coal capabile stack & stove; this summer I’m building a coal bin. At $120/ton and a BTU rating per ton => 2X a cord of low quality locally available fire wood, I’ll do my share as well.
As a bonus, it will be nice not to have to put wood in the stove every hour or two, since the coal has a much longer burn time.
