If you have a HOT fireplace room in your house which direction should ceiling fan blades turn to push the heat into OTHER rooms?

You will likely find that a ceiling fan will not satisfactorily circulate air between rooms. However, you will find that setting the fan rotation to circulate air from the ceiling to the floor will maintain a more even room temperature since hot air rises.

Some people prefer to set their fans so it pulls the air from the floor to the ceiling if the draft from the fan is uncomfortable.
