When You Turn On Your Heat – Set Your Ceiling Fan
First, they cool a home by gently circulating air during the hot summer months and, second, when blades are reversed, they warm a room by bringing heated air down from up above. Third, that same movement of warm air helps dry up condensation on window interiors and cold, clammy walls. That’s a three-ring performance that’s hard to beat.
If your ceiling fan has a reverse switch, use it to run the fan’s blades in a direction where the leading edge is lower than the trailing edge. Energy Star says the fan will produce an updraft and push warm air from the ceiling down into the room.
This is especially helpful in rooms with high ceilings — and it might even allow you to turn down your thermostat by a degree or two for even greater energy savings.
