Ceiling fans keep you cooler in summer and warmer in winter using about as much power as a 60-watt light bulb, which costs only 2-3c per hour to run. Choose a fan with a DC motor, which uses 70% less energy than standard AC fans, and you’ll reduce running costs to as little as 1c per hour.
Fans in summer
While a ceiling fan does not necessarily lower the temperature, it does make the room feel cooler by providing a circulatory breeze. Effective circulation can make you feel up to 8 degrees cooler and reduce air conditioning bills by up to 40%.
Fans in Winter
In the winter months, you should run your ceiling fan in the reverse mode. This pushes warm air up against the ceiling and then down the walls, gently re-circulating warm air through the room. This technique has been proven to lower heating costs by as much as 10%. The calculations on costs and savings are approximate only and may vary according to fan size and use of fan.
