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. |

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. |
