I had planned on keeping very close track of my coal used, but with all my AA Boiler 'growing pains', I reburnt a lot of ash with high percentages of unburnt coal in the other boiler, and certainly with all the challenges, did not keep up with the number of 5 gallon buckets of coal that I dumped in the hopper..
So I have to guesstimate...From looking at the shrinkage of the piles of coal... I'm going to say I've burnt around 5 tons since the first part of November...Not bad considering the amount of propane I would have burnt to keep the house and shop at the same temperature..
Even if I'm off by a ton or two, say I've burnt 7 tons, at $200/ton delivered, I've spent $1400 so far this season... I would have spent that in one 30 day period keeping the house at 60* instead of 70, and the shop at 35* instead of 45*.
So I'd say even being extravagant with heat use, coal costs me 1/3 or 1/4 what propane would.
