Ceiling Fans - An Ancient Discovery that Changed the World Forever If you think Ceiling fans are a thing from the past, and that they have been made obsolete by air conditioning units, youre wrong. Please dont take it personally, most people think exactly the same as you - but it still doesnt make it right. Heating and cooling systems are something that people have looked for since the dawn of time (well, at least since the human race started worrying about comfort). Thousands of years ago, ancient civilizations were already using fan systems to move the air around, to cool them down. Of course, back then this was something only the most powerful and influent people could afford, the majority of the population had to deal with heat and cold any other way they could. Thousands of years had to go by until the rest of the population could use similar fan systems to turn their homes more comfortable. It was the introduction of the ceiling fans. Although not as "exotic" as having someone slowly fanning some palm tree leafs over your head, ceiling fans are much more efficient at moving air. And everyone knows how much better it feels to have a breeze blowing over you on those hot summer days. Even though the air is at the exact same temperature as its surrounding environment, the air movement has a chill affect that helps lower the skin temperature. Think of it as traveling in your car on a hot summer day with the windows full open... doesnt it feel good? Thats exactly the same thermodynamic principle that has been known for thousands of years - well before cars were invented. Benefits of your ceiling fans With the advent of electricity, ceiling fans quickly spread throughout the world, becoming the standard cooling method in every enclosed space you can imagine: houses, stores, movie theaters, you name it. Even though one thinks mostly of ceiling fans to fight the hot weather, they are also pretty useful to help warm up the environment. When used together with any form of heating equipment, ceiling fans make a wonderful maximizing efficiency. As everyone knows, hot air rises - therefore, warm air will inevitably rise up until its close to your ceiling - not the most efficient place to be. Using your ceiling fan spinning in the opposite direction will help spread the warm air around, meaning youll make big savings in your heating bill. Most ceiling fans come with a "winter/summer" switch for that exact reason. Youll be able to use it all year round - its not just a "summer" device. Thats why you still see industrial ceiling fans in most shopping malls and any wide-open area stores. Even though they have big and powerful air conditioning units running continuously, the ceiling fans help maximize its efficiency. And the exact same thing is true if you use it in at home. Even if you have a furnace or air conditioning units, you should still consider installing ceiling fans. Often, just turning on the ceiling fan will be enough to cool everyone down, saving you from turning on your air conditioning system. And in those really hot days you need to turn the AC on, the ceiling fans will help reach a comfortable environment around your house much faster. And the same thing applies to those cold winter days, when you have to have to heat your place. Ceiling fan shapes, styles and design Its amazing how a simple device whose working principle has been invented thousands of years ago, is still widely used today. Even though we now have more evolved heating and cooling methods available, the ceiling fan can (and should) still be used to good use. When you consider the low cost of a ceiling fan, it really is a no-brainer: youll quickly recover your money with the savings in your heating/cooling energy bill. And dont worry about ruining your homes décor - in fact, there are so many different styles of ceiling fans available, that it will even help improve your house décor. You need to see it to believe it: there are ceiling fans in all shapes and sizes, suitable for any room you can imagine. There are even those suited for children rooms like the kid ceiling fan, with slower spinning speeds and flexible ceiling fan blades, and rugged enough to resist whatever your kids might throw at it. And then you have those with exotic blade shapes and patterns that turn your house into a relaxing and magical resting place, the perfect place for you return to after a stressful working day. Whatever your choice is, youll definitely benefit with some ceiling fans hanging from your ceiling. Be sure to check around the internet to find the best discount ceiling fans of your choosing - a few easy mouse clicks can quickly save you some valuable dollars. Choosing a brand like Hunter or Casablanca ceiling fans that offers you easy to find ceiling fan replaceable spare parts, it might come in handy a few years from now if you ever need to repair it. Whether you choose to install it yourself (most kits come ready with ceiling fan installation directions and can be installed by anyone with rudimentary skills) or have it installed by professionals, youll soon be asking yourself why havent you done this sooner.
Ceiling Fans Leading the Future The Current Market Ceiling fans have been gaining in popularity for the past 20 years. What started as a cost effective alternative to air conditioning to cool your living room bedroom or kitchen has grown into a multi-billion dollar industry. Ceiling fans are now offered in many styles and price ranges from the very basic to high end designer styles. They can cost from less than one hundred to several thousand dollars and are being made to suit any taste or preference. The ceiling fan manufacturing industry has evolved to provide very high quality fans at reasonable costs and has built the consumer market for these products. This led to explosive growth in the sales of fans through the home improvement retailers like Home Depot, Lowes and others. The days of showroom sales for the mid to high level fans may be in for a change due the marketing efforts of these industry giants. Marketing data suggests that approximately 70% of all ceiling fans are being installed by the homeowner within 2 years of occupying their home. They are replacing the existing lighting fixtures with higher grade fixtures and ceiling fans in the bedroom and kitchen area. The living room is also a popular choice for fixture replacement with ceiling fan and lighting kit combinations being installed in greater numbers. The consumer is faced with so many choices in the market today that it can be a bewildering experience for todays consumer. The average purchaser is going down to their favorite home improvement store to choose their new fan or lighting fixture or even making their choice on the internet. They come to a lighting specialty store or showroom only after being overwhelmed by the choices in the home improvement stores aisles which provide little if any service or assistance. The choice of fans today is greater than at any time in past 5 to 10 years. Many of the major brands are also selling products in the home improvement market. Companies like Hunter are distributing several models in Home Depot this trend is expected to increase as they gain market share. Changing Technology Numerous manufacturers have been paying attention to this trend in the consumer market and are providing fans that meet the needs of todays consumer. The ease of assembly and use of pre-assembled components speed the installation of their products. Westinghouse Lighting Corporation has a line of fans that captures all of these needs and they claim can be installed in 15 minutes on average. The weak link in all of these improvements is the ceiling box itself. This is the component that the fan is attached to and must bear the static and dynamic loads of the fans operation. It also houses the electrical wiring for the fan. This utilitarian component has been under going improvement for the past 10 years or more to make its installation quicker, cheaper and easier than the traditional metal box of yesterday. The electrical contractor of today is using products that increase his productivity and maximize the potential profit of his labor. They have a large choice of nail-on products that already have the fasteners attached to the ceiling box and all they have to do is hold it in place and nail or screw it into a joist or truss for it to be secured. Many of these boxes are thermoplastics which are inexpensive and easy to manufacture. They also have the added advantage of not needing to be electrically grounded so this saves the additional labor that metal boxes require. This fact is not lost on the ceiling box manufacturers that are producing ceiling, outlet and junction boxes that are quick to install and are made of plastics that require less and less labor to install properly. This has gotten to the point that there is now a lighting box that only needs to be pushed onto a wooden stud for it to be secured; no fasteners are needed at all! The ceiling fan manufacturers however may not be keeping pace with the trend in ceiling box installation practices. They advise the consumer of their products to reinforce or replace the existing fixture with a fan-rated ceiling box which is prudent, though are the consumers heeding their installation directives? The installation instructions for many of the fans available today show a metal type box that has screws going through the box and into blocking above the box. This is not what is installed in most of the newer construction homes which use the labor saving nail-on products. As a general rule builders and contractors do not provide blocking above the ceiling box with a nail-on product as the added material & labor is not cost effective. The average nail-on plastic ceiling box is rated for only supporting a 35 pound static load. They are also not fan-rated. This requires that the ceiling box be replaced with a fan-rated box before the installation of a ceiling fan. Fan-rated boxes are capable of holding 70 pound loads and are rated for this application. This is easier said than done! The nail-on products do not lend themselves to be reinforced easily since labor savings have also been applied to the construction of homes themselves. In many circumstance the average home does not have an attic, only a narrow crawl space between the trusses is provided. This combined with blow-in insulation makes the location of the ceiling box difficult if not impossible when a fan is to be hung on an upper floor. For installation of a ceiling fan between floors leaves little choice for this task since it cannot be accessed easily from above or below the ceiling since the upper floor is directly above the ceiling box. Cutting a hole in the floor or knocking out the ceiling is not prudent just to place blocking above a ceiling box. Medallions are available but the added expense, labor and time can be prohibitive, especially if the medallion is painted to match the ceiling. The brace type of products that are sold today are an alternative though they work better in theory than in practice as the old ceiling box needs to be removed before they can be installed. Home Depot has a web page devoted to this process which they claim can take ½ a day to complete. A Better Way Following the trends used in the construction methods of todays homes has led to the development of a new and simple method to reinforce an existing ceiling box to that of a fan-rated box that is consumer friendly. Access is gained through the ceiling box itself with a small bracket being utilized in what is in most cases is wasted space within the ceiling box itself. Two fasteners are driven through the ceiling box and into the joist or truss with the bracket being firmly held in position. This bracket has been shown by independent testing by a leading product testing laboratory to allow the ceiling box to sustain very large dynamic loads. This testing revealed that ordinary thermoplastic ceiling boxes that are reinforced in this manner are capable of sustaining loads that are factors above the requirements of NEC (314.27D & 422.18). These NEC building codes apply to the installation of ceiling fans and fan-rated ceiling boxes. Another added feature is that this product installs in only 2 minutes or less with common hand tools and allows the installation of a ceiling fan to be accomplished in less than an hour from start to finish. If the Westinghouse fans were to be used with this product it could be done in 17 minutes or less! The product can also be also used with metal boxes after 2 holes have been drilled in the ceiling box. Failure modes during product testing revealed that the test plate was being pulled off of the ceiling box. The ceiling box is left intact and firmly secured to the simulated test truss. A grounding lug and screw is provided on the bracket to facilitate grounding of the pierced ceiling box to alleviate any concerns regarding an energized component outside of the ceiling box.

Why Do Ceiling Fans Have a Reversing Switch? What is the reason for having a reverse button on ceiling fans? Well "they" say that you cannot stand a draft during winter months, but that you can equalize the air temperature buy using your fan in the reverse direction. I always wondered why the older ceiling fans did not have a reverse button. Were the people who designed those fans, just too stupid to think about using reverse in winter? During winter, when you use the central heating system, the warm air coming out of the registers, in each room, will naturally rise and because the registers are up high already, the hot air will build at the ceiling level and gradually work its way down toward floor level. The heating unit runs until the temperature is comfortable at the lower levels of the rooms. But by the time this happens, it will be very hot at the ceiling level. Many BTUs are wasting heating the ceiling areas of the home, where we dont live our lives. But what if there was a way to get this hot air down off the ceiling, to the lower levels where we live. The heating unit would not need to work as long and the savings on our utility bill could be significant. AHH CEILING FANS! will bring this air down and mix the hot air with the cooler air at floor level. This mixing would basically equalize the temperature at floor and ceiling levels, which means that the heat would not be wasted keeping the ceilings warm. The heating unit would not run as much. The utility bill will be lower while the comfort level will remain the same. But then someone said that the draft created by the ceiling fans would be too much for winter months. So someone else said "well, lets just reverse the ceiling fans and let the air blow up until it hits the ceiling and then it will go horizontal in all directions until it hits the walls. Then it will come down vertically until it hits the floor. Now it will travel, at floor level, back in toward the center of the room and then back up to the ceiling fan. What a genius! Now everyone can use ceiling fans to equalize the temperature without feeling a draft in winter. Oh yea! So what happens when this warm air starts down the walls and hits furniture, bookshelves, etc? It will start a horizontal movement toward the center of the room. Now when it comes out past the obstruction, will it turn and fall toward the floor, where it can mix? If warm air falls instead of rising, then I guess it could. What happens when air from the ceiling fans hits the ceiling in a room with a sloped ceiling? If the ceiling fan is centered in the room, it would be basically half way up the slope. So wouldnt all the air go directly up the slope from where the ceiling fan is mounted? What about the other half of the room? What happens when the room is large? Will the force, coming down the walls, still be enough to get this warm air to the floor, especially when the ceiling is two stories high? What happens when ceiling fans are in a room with a two story high ceiling, which is open to the second floor level of the home? Wouldnt the warm air go off into the second level, instead of coming down to the floor and in this situation, wouldnt the ceiling fan steal the warm air from the first level and take it to the second floor, defeating the purpose for which it is being used? On the other hand, if you blow the air down, the hot air at the ceiling level will be forced down to floor level where it will move in all directions toward the outer walls of the room. The air can now mix and seek its own level. The hotter air will naturally rise to the ceiling level where it will be picked up by the fan to repeat the cycle. So wouldnt this be much more efficient than using reverse, especially in the scenario where the ceiling is two stories high and open to the second floor? But what about the draft? I say just run the ceiling fan at a low speed or the highest speed that you can tolerate and still be comfortable. Could reverse on ceiling fans be a marketing tool to sell fans in winter? You decide. But I do not think that the old folks overlooked something as important as this. I think that they used what was most efficient. I agree and my ceiling fans always blow down, winter and summer. And if you happen to have a room with the two story ceiling where the room is open to the second level, and where you notice the upstairs is always hot while the lower level is cold during winter, try using your ceiling fans in the down direction. You will not believe the difference!
Ceiling Fans - A Green Way to Heat and Cool Ceiling fans can help alleviate both the heat and the climbing energy bill. By circulating the air ceiling fans move warm air toward the ceiling and into attic vents while creating a "wind-chill" effect, which adds to the cooling sensation. Air conditioners are not known to be very energy efficient. Even the most advanced units use more power than other appliances in most homes. Annually air conditioners use almost 20% of the kilowatt-hours produced in the United States. In other words, air conditioners alone in the United States are responsible for the consumption of 207,0692,000 tons of coal, 23,074,000 barrels of oil, and over 137,924,800,000 cubic feet of natural gas (based on 2006 national statistics). That staggering figure translates directly to an increased energy bill and money out of your pocket. Most ceiling fans use the same amount of power as a 75-100 watt light bulb. For such a small power usage a fan can make a home or office feel 8-10F degrees cooler. According to Florida Power and Light, ceiling fans throughout a home can reduce energy bills by up to 40%. While serving an energy saving function, fans can also accentuate the style and decor in your home or office. Ceiling fan innovation and style have come a long way. What to look for when buying a Ceiling Fan: At first glance it may be hard to see why one fan costs $50 and another costs $600. Part if it may have to do with style and appearance, but beyond that the quality of the higher priced fans are generally superior. Quality fans pay attention to blade angle, use higher quality internal components and are better engineered. Cheaper fans will probably function reasonably well at first, but they can quickly begin to generate noise, and wobble. Wobbling in a fan further speeds up the wear and tear on a fan. Higher quality fans also move more air than a low quality fan of the same size. Ideal blade angle for a traditional ceiling fan is 12-16 degrees. Most cheap fans have a blade angle of 10 degrees or less. On the same size fan this small difference can make a difference of the cheaper fan moving 40% less air. In other words, a cheap fan with 10 degree blades designed to cool a room effectively cools a room roughly half as large. Fan Sizes and Location: Traditional fans should be hung in the center of a room. Fan blades should be 7-8 feet from the floor for optimum air circulation. Low profile fans, for lower ceilings, and lengthening stems, for higher ceilings are generally available with fans to ensure they are mounted at their ideal height. Below a chart shows the approximate size fans should be based on room size Room Size-------------------------Fan Size 64 square-feet or smaller---------32-inch or smaller 100 square-feet or smaller--------34-inch or 36-inch 144 square-feet or smaller--------38-inch to 42-inch 225 square-feet-------------------44-inch to 46-inch 400 square-feet-------------------48-inch to 54-inch 485 square-feet-------------------56-inch 600 square-feet-------------------58-inch to 60-inch Nontraditional Fans: Directional fans, as the name implies, are stationary fans designed to cool a specific location or area. Some directional fans swivel to cool a greater area. Generally directional fans have stronger motors and sharper blade angles to move air more aggressively, but otherwise follow the same general quality guidelines as the traditional fans. Directional fans can be great to further cool a room that already has a traditional fan or on its own. Rotational Fans are a hybrid of Traditional and Directional fans. The fan is ceiling mounted like a traditional fan, but in place of fan blades a horizontal stem is attached to directional fans on either end. These directional fans rotate around the ceiling mount and are adjustable to different angles as desired. It has been claimed that rotational fans move the air most effectively, however the movement of air is the objective and which fan is the right fan is a matter of personal choice. Lastly, an often-overlooked benefit to ceiling fans is they also help with heating. Most fans have a switch that will change the direction of the blade rotation from pulling air from below toward the ceiling (usually clockwise rotation) to moving the warm air from the ceiling toward the rest of the room (usually counterclockwise direction). Generally the fan will be set to a slower setting to accomplish this without any "wind chill" effect, but it is a proven and undeniable benefit.
