Switch your ceiling fan to the reverse setting. The ceiling fan will now spin clockwise, which will push the hot air gathered on the ceiling down to where you will be able to feel the extra heat.
Keep the ceiling fan on its lowest setting. It doesn't need a lot of energy to push the hot air down, and a higher setting will only make the room breezier.
Turn down your furnace. Before the ceiling fan was on, your heater was putting out more hot air than it needed because it wasn't recognizing all of the hot air up toward their ceiling. Now that the fan is pushing that hot hair back down, your home will be heated more efficiently.
