But more efficiently than burning the coal in a furnace.

Usually not.


Invariably not. Average coal to wall socket efficiency is around 35%.

Newest multi cycle coal plants approach 60 percent efficiency.

Further, they can power a heat pump with a SEER of 16 or so that completely blows away any conventional coal furnace.
