Cooling Benefits of Ceiling Fans
Category Design Tips
Air-conditioning (ACs) units can use almost as much power to keep you cool as a heater does to keep you warm in winter. For example, a single 1500w window or room AC running six hours a day will cost you an estimated R500 a month to run at current RSA electricity tariffs.
In addition, all those ACs going full blast in our homes, shops and offices put strain on an already overtaxed power grid.
These are just a couple of reasons why budget-conscious and enviromentally aware homeowners are increasingly returning to an old favourite the ceiling fan, which produces a natural 'wind-chill' effect that immediately makes one feel cooler, whatever the temperature may be, and will typically cost about R40 to R50 a month to run.
To get the full cooling benefits from a ceiling fan, you must install the right size fan in the right position. Sizes generally run from about 1m to 2m across and optimal air circulation occurs in square areas. A 1.5m fan will suit a 3m x 3m room, for example, but if you colling a large rectangular room, you should use two or more fans, evenly spaced.
Good to Know
*Most manufacturers recommend a 3m fan-to-floor distance if possible and for safety reasons, a ceiling fan should never be mounted less than 2m from the floor.
*Ceiling fans, should be securely anchored to a sturdy roof truss or beam and should be professionally installed. An electrician will need to certify its safety as part of your home's electrical system, or it could void your home owner's insurance cover.
*Another factor to consider is the number of fan baldes and the materials they are made from. To work properly, ceiling fans should ideally have three to six blades. Uneven blades will cause the fan to wobble. It is thus important to select fans with rust-free finishes and blades that won't warp - especially in damp coastal climates.
*If you're replacing an overhead light with a fan/light combination you need to decide what controls to look for. Options include pull chains, wall mounted control boxes and, with many newer models, hanheld remotes.
