Use A Ceiling Fan in the Winter to save Money

Using a ceiling fan in winter may seem counter-intuitive, but it’s actually a very simple idea that can save you a lot of money on your heating bills.
HOW it works:
Everyone knows warm air rises and cool air sinks. The same principle is what makes hot air balloons fly. Ceiling fans are typically used in the summer to force cool air from the ground upward (by spinning counter-clockwise), helping to circulate the temperature throughout the room and creating a breeze. However, In the winter you can reverse the direction of your ceiling fan's motor (clockwise) to bring warm air down to the lower half of the room.

Forced Air vs. Heating With Fan WHY it works:
Because hot air rises, most of the heat produced by your heater rises to the ceiling before it can even be felt. In a room with high ceilings, the top few feet of the room can get up to 20 degrees hotter than your thermostat setting - ultimately wasting a lot of energy.

Running a ceiling fan in reverse can bring all the hot air trapped near the ceiling back down toward the floor. This helps circulate warmth, and means your thermostat doesn’t have to work as hard to heat the room.
Don't ceiling fans use energy too?
Yes, ceiling fans do use energy to operate, but not nearly as much as a conventional heating system. A fan with a 48" blade-span typically uses no more energy than a single 75 watt light bulb, so using a ceiling fan in conjunction with your central heating and cooling system is a simple and effective way to help conserve energy year-round.
