What every homeowner should know about ceiling fans
Monday, April 23, 2012
Ceiling fans are useful in nearly every home space and in virtually every decor. They are also a necessary element for homeowners who desire to cut utility bills. If you need a ceiling fan, it’s easy to get lost in the many available options.
The American Lighting Association offers the following tips about how to use ceiling fans, integrate them into a decorating scheme and size them specifically for your rooms.
Ceiling fans serve three primary purposes; the first is air movement.
“In summer, ceiling fans create a ‘wind chill’ effect that makes the room feel 6 to 8 degrees cooler than the actual ambient temperature,” said Joseph Rey-Barreau, associate professor in the College of Design at the University of Kentucky. “In winter, the direction of the blade movement can be set to a counter-clockwise direction, which will help to move the hotter air at the ceiling toward the edges of the room and then downward. This distributes the heated air more efficiently.”
That is key to consumers’ interest in and need for ceiling fans.
“That air movement can help reduce heating and air conditioning bills in homes,” said Maria Scutaro, president of Murray Feiss Lighting/Monte Carlo Fan Co.
Manufacturers have also adapted ceiling fans to fit the smallest of spaces — even in closets — with a single blade and minimal motor that leaves the ceiling fan able to hug the ceiling. In addition, ceiling fans are a decorative element and focal point for interior design — a big change from the 1990s.
“There is an unlimited range of fan styles and designs as well as fans that are part of a ‘family’ of lighting fixtures,” Rey-Barreau said.
As a light source, ceiling fans can range from a night light to ambient light to a fully directed light source. According to Scutaro, “LED technology is bringing light and additional energy efficiency to fans.”
While the Energy Star label gives homeowners guidance about which appliances can save on utilities, ceiling fans can also be rated Energy Star compliant. To do that, those ceiling fans must use efficient motors and advanced blade design to meet or exceed minimum requirements for airflow efficiency set by the U.S. Environmental Protection Agency.
Energy Star ceiling fans also carry three warranties: a minimum 30-year on the motor, a one-year on other components and two-year on lighting.
“Lighting for Energy Star-qualified fans also uses efficient compact fluorescent sources that use two-thirds less energy and produce 70 percent less heat than incandescent bulbs,” Rey-Barreau said.
Three location ratings
Ceiling fans used indoors in protected spaces differ from those used in semi-protected or exterior spaces. An indoor use rating means a fan can be used only indoors. Those rated damp use can be used outdoors if in a covered spot, such as a porch. An outdoor use rating means the fan can be used in a location where it will be exposed directly to water, such as over a patio that is located underneath a deck.
One common mistake
“The better quality fans do not cost much more than the most inexpensive fans,” Rey-Barreau said. “A consumer should purchase a fan that has a good motor and is energy efficient. Buying a very inexpensive fan can be problematic in terms of performance.”
In order for a ceiling fan to effectively heat and cool a space, it must be sized for the square footage of the room. Use these room measurements as guidelines:
Less than 50 square feet — 29-inch fan
75 square feet — 36-inch fan
100 square feet — 42-inch fan
225 square feet — 52-inch fan
300 square feet — 56-inch fan
More than 300 square feet — a 60-inch fan or two 56-inch or 52-inch fans
