Just wanted to post an update. As I figured, this coal is the BOMB! I made it a couple days shy of two months on a ton of Direnzo's buck. Ash pan dumps were sometimes a couple weeks apart. The load was always my domestic hot water plus the unexpected heating from the cold spring we've been having. For me, really great mileage out of a ton. So with regrets, i filled the bin with big named bags. The bin holds 1200 lbs if I heap it up perfectly. Well, with pretty much just the same load as has been running the last two, three weeks, I've blown thru almost 1/3 - 1/2 the bin in 9 days. Took out considerable ash. I can't let this coal go too long because the pan overflows too quickly. Just can't believe there is that big of a difference between the two. I gotta get some more of that buck!
