Just got my new TLC-2000 installed today, my first coal stove.
I also have a US-STove "Franklin" recast made in the late 70's early 80s, but have only ever run wood in it.
The Harman replaces a godawful large wood-burner (flat bottom) that never held a consistant fire, and smoked to high heaven.
Anyway.. thanks to the insightful and informative info found here, I lit the first wood fire in it at 11:00, had coal running by 2:00 (after wood-firing it to 400 for two hours, to cure the stove) and am now ready to damp it down for the night and let it go!
I heard enough horror stories about how bad coal was.. but this is _far_ easier to deal with than a finicky wood fire, and far FAR more stable/even as far as heat goes.
Running Reading Anthracite bag coal, btw. Will probably do bags for the rest of this season, then try to find a good local supplier. I'm about an hour from Pottsville/Schuylkill cty.. so I could probably just take my trailer up, find an abandoned tailings pile, and mine my own.
