Coal cost here in the Boston area is high, about $325 a ton picked up. They tack on a high fuel charge.
Takes about 1-1/2 tons for a cold winter.
For comparison,
The shop is 1000 sq.ft., 16ft to the joists, 3-1/2" insulation walls, 2" rigid insulation between the rafters under the roof. Insulated doors. 50F minimum (45 if below 0 out), 65 or better when working. (too old to enjoy the cold)
