Cutting the cost

Plain bar and fan heaters turn power straight into heat, so no brand runs cheaper than another; the only real saving is heating less. Warm the person, not the whole room: shut the door, point it where you sit, and put it on a timer so it isn't left running. If you own a reverse-cycle unit, it delivers far more warmth for the same power.
