I don't think the other members of the forum are set to talk anyone out of burning coal. They (as well as I) responded to your questions as best they could.
The point is: Heating with coal is A LOT of work. Also, it can be costly, especially if you have to pay others to do the installation and related work for you.
I have heated with wood and now coal for almost 18 years, using oil heat only as a back-up. I have cut and split wood both by hand and using a splitter, moved cords and cords of delivered firewood, shoveled tons of coal, even once used a Flexable Flyer sled to bring wood from the shed to the house after a really bad blizzard.
We would love to add another coal burning friend to the list. We just want to make sure you know what you are getting in to.
I'm sure it was easier when (back in the day) everyone heated with coal, there were lots of coal companies willing to deliver, etc. I'm too young to remember that, but I would guess some of the particulars of coal burning were common knowledge. I remember oil companies advertising "Quiet Automatic Oil Heat" and seeing old scary looking boilers with oil or gas burners fitted to them.
So I hope this clears things up a bit. If you do go with coal, welcome.
