Weather bit or anth coal has different amounts also. I know there are alot of variables to take into consideration, but this isn't for scientific research so averages are fine.
I'm no expert, but I understand that with a good anth appliance, you will burn less coal per btu going to the heated space. Not because anth has more gross btu [some bit is actually higher], but because the appliance can be made more efficient. So, you get to use more of the heat, instead of sending it up the flue. My Keystoker Kaa-2 is rated at 84%, and some more pricey boilers are higher than that. I doubt that an affordable device that can burn bit can be made to be that efficient, due to the volume of flue gas and what it contains.
