I use a 10KW electric furnace mounted with the outlet on the floor. The shop is only 18' X 24', so even on those chilly Canadian winter nights (-20 Celcius not uncommon), I can get up to a reasonable temperature in about 2 hours.
To make things even more pleasant, I use the 2 wires in the phone line that aren't needed for the phone to connect the thermostat from a wall switch in the house. That way, I come home from work, turn it on, and by the time I'm ready to go out, it's started to heat up.
