The popularity of ceiling fans continues to grow as more and more homeowners discover dramatic, year-round energy savings. In summer, ceiling fans make cooling breezes, which reduce the try on air conditioners. In winter, they circulate heated air to hold back the elbow room warm.
Instalmen a ceiling fan is comparatively simple, especially if the space above is accessible from an attic. Still, even when it isn't, the job is still quite doable. Hither, we'll show how to replace an long-ago light fixture with a new ceiling lover and light, in a room with no attic above. The advantage of this border on is that you wear't have to run new wiring. The fan connects to the existing cable from the old light.
However—and this is very important—you fundament't just bent the devotee from the existing electrical box. It's just not strong enough to support the added weighting and vibration of a fan. Presuming you don't take access to the cap fan from above, you must either use a specially rated hanger and box seat to mount the sports fan between joists or, better yet, screw a devotee-rated "pancake" box (so called because it's very thin) directly to a ceiling joist.
Optimal Sizing, Speed, and Placement
Expend this formula to find the best buff size for a way's occupied space (the part of the board where people gather the about): Occupied space (in square feet) mullioned by 4 equals the steel span (in inches). Step blade span shoot down a little for rooms with low ceilings, and go wider if the ceilings are high.
Other good find of hitch is to think back that brand spans of less than 36 inches are ideal for spaces smaller than 75 square feet, such as baths and breakfast nooks. Spans of 36 to 42 inches knead in suite of busy 225 square feet, like a dining room. Large living rooms and bedrooms can plow 50- to 54-inch blades.
Make predestined that the cubic feet of airwave that the fan moves per microscopical (cfm), measured at high speed, is near the top of its class. Some 52-inch fans, for instance, rate as low as 2,050 cfm, piece others reach 7,800. High-cfm fans not only allow for a better breeze, they usually have strong motors that will penultimate longer and run more quietly.
For optimal performance, the fan should be hung at least 1 1/2 feet from the wall or a slanting ceiling, 7- to 10-feet from the floor, and at least 8 inches from the cap. Steer make of hanging the lover too tightlipped to some lights, as rotating blades under a electric-light bulb will create an annoying flicker.
