This is not real scientific but I know my neighbor is feeding two pellet stoves with fuel that is much more per ton then the coal I am burning and he still has to run his furnace. Comparing coal to pellets is like comparing a super model to Rosie O'Donnel. Not even the same species!

The only problem with your conclusion is you can have 50lb bag with 5% ash that produces 65K BTU and the other 50lb. bag with 10% ash that also produces 65K BTU. The ash content and the BTU don't necessarily correlate.pconn171 wrote: The truth is that we measure the heat output of coal in Btu's/pound so if you have coal that produces more ash - that ash component was there before it was burned, therefore the two bags of coal would contain 2 different amounts of combustible material based on weight.
