Ceiling fans provide years of comfort and beauty. They only use as much energy as a 100 watt light bulb. Most ceiling fans should be placed in the center of the room. This allows smooth air flow throughout the room. However, larger rooms may be better suited for two fans for optimal air flow. For the most efficient air circulation it’s best to have the fan blade higher than 7 feet above the floor. Optimal placement is 8 or 9 feet from the floor. For higher ceilings, a fan downrod can be attached.
To get the most out of a ceiling fan, it’s important to select the right size. Choose a 36 inch diameter fan if the room dimension is 12 feet or less, choose a 42 inch diameter fan if the room dimension is 12 to 15 feet, and choose a 52 inch diameter fan if the room dimension is 15 to 18 feet. Fans should run clockwise in winter (to move warm air off of the ceiling) and counterclockwise in summer (to create a cool breeze). Fan blades determine the amount of air being circulated. The blade pitch is also important, as it along with the blade span is what determines the degree a fan cools a room. The steeper the pitch, the more effective the fan will be in moving the air. Look for blade pitches that are between 11° and 16° and weighed and matched as a balanced set to avoid having your fan wobble. The greater the angle of the blade the more air circulation you will receive.
If the fan includes a light fixture, ensure that the circuit is able to handle both the fan and light. Also, look for the Energy Star label which indicates that air moves 20% more efficiently than other models.
Floor and Table Fans
Fans, also known as air circulators, can be the perfect solution to meet light cooling needs. In more temperate climates, they’re an excellent alternative to having an air conditioner that may not see much use, cost much more to buy, and use far more energy. In hotter or more humid climates, fans can help ventilate and dry an area while cooling it, or they can supplement existing air conditioning systems.
Fan Style and Design
Fans for the home are categorized by style and design and include:
Tower fans have a long, vertical housing unit that includes a cooling apparatus that runs the length of the fan. They conserve space and offer greater blade protection than more traditional fans.
Pedestal fans feature a conventional fan design perched on a long stand to reach higher areas than a floor or table fan. They are useful for cooling areas off the ground without needing a desk or shelf for support.
Table fans can rest on a table, desk, shelf, or other stationary object. These fans are generally smaller air circulators that are convenient and mobile.
Floor fans sit on the floor and have a variety of uses. They tend to be larger than other types of fans and are often used in commercial and industrial applications.
