New Energy Star Ceiling Fan is Over 300% More Efficient! Having been in the ceiling fan business for over 20 years, it is rare that a new ceiling fan gets me excited. But while researching the efficiency ratings of the latest introductions this year, one model clearly stood out among all others. The Midway Eco from Emerson Electric, which is an impressive new Energy Star Ceiling Fan that is Over 300% More Efficient than other fans. This represents a major breakthrough in ceiling fan performance and technology, setting a new standard for energy efficient ceiling fans. Emerson developed an entirely new motor for the Midway Eco Ceiling Fans called the "EcoMotor TM". The EcoMotor TM uses up to 75% less energy compared to other ceiling fans. The blades have an airfoil shape for better aerodynamics and move up to 40% more air than typical fan blades. The built-in light uses four 13 watt fluorescent lamps to provide maximum illumination at a very low wattage. With these new innovations, the Emerson Midway Eco far surpassed the Energy Star testing requirements established by the EPA. As a matter of fact, the test results prove it to be over 3 times (or 300%) more energy efficient than any other Energy Star ceiling fans with lights. This means that the Midway Eco will move substantially more air while using a fraction of the electricity making it the ultimate choice for energy conscious consumers who wish to reduce their carbon footprint. Although Emerson does not claim that the Midway Eco is 300% more efficient than other fans, I made this observation myself after reviewing the test results published by the EPA, for ALL Energy Star Ceiling Fans with lights. In order for any ceiling fan to be Energy Star qualified, it must meet EPA standards for quality and durability. But most important, it must undergo a standardized testing procedure adopted by the EPA to calculate the efficiency of the fan. During the test, sensors measure the CFMs (Cubic Feet per Minute) of airflow the fan produces while recording the amount of electricity it consumes. The efficiency rating is calculated by dividing the CFMs produced by the Watts consumed (CFM/WATTS). This information is labeled on the fan packaging of every Energy Star ceiling fan giving consumers a standardized way of comparing the performance between different models. For such a comparison is critical for those who are energy conscious. As you will see in the data below, there are substantial differences in the efficiency ratings of many Energy Star ceiling fans. The data that I used to perform my analysis is published by the EPA and can be found at www.energystar.gov. If you wish to confirm my observations, download the spreadsheet under Ceiling Fans with Light Kits named "ceiling_fan_with_lightkit_prod_list.xls". Here are my findings based that data: There are 126 Energy Star ceiling fans in total, which represents all of the various finishes available for each model. I removed the finish variations to get to the actual base models since each finish is just a duplicate of the actual fan. This brought the total down to 33 Energy Star qualified ceiling fans with lights available in the USA from all brands combined. The table below represents my findings sorted by the most efficient to the least efficient. The Emerson Midway Eco is at the top with an efficiency rating of 620.20 CFM/Watt on Low Speed, 476.6 CFM/Watt on Medium and 289.0 CFM/Watt on High.
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.

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.
