I'm an old wood-burner. Been burning coal for 5 yrs. 4 in a Yukon Eagle and 1 in a Chubby.I almost gave up with the Yukon. The first year, I threw out more coal than I burnt. I'm a slow learner, but after finding this site, I'm a pretty fast catcher-upper!
I've only used Reading. It's pre-washed with something. No dust. It's clean burning in the Chubby. I get 24 hrs. out of a 40lb bag, when it's 20* outside-68-70* inside. House is a one floor, 1500s/ft ranch, built in 1954.
When I was picking up my coal today, a customer was buying 4 bags, so, I guess they will break down a pallet. You might want to try it, if the price is right.
