When you don't have to haul it a million miles,or,better yet,when you can pick it up at the mine,I think you'll hit your true savings on using coal. Heck,Brckwlt built the Coalfire to haul the black gold from UAE Harmony,just think of what you could come up with. Do your homework,research the threads on this board. There is a treasure trove of info,experience and opinions on how to burn it safely and wisely. A stove or boiler is simply a tool...period. Learn how to use the right tool before you buy it,and your savings and security will rise.
