I have a few hundred pounds of anthracite for the fireplace and woodburners. I use it all the time in the pole barn woodburners but not in the house. Most is for a Mad Max scenario.

I also rigged up my own oil dripper for the pole barn burner. I burn all my used oil in it in the winter time. Really adds to the BTUs. Keep in mind that my pole barn is also the central location for my company. It is the sales office, the maintenance facility and the materials shed.
