Ceiling fans cool you in the summer and warm you in the winter, all for just pennies a day. They are extremely efficient: even at high speeds they use less energy than a 75-watt light bulb. Actually, fans save energy, with cooling costs alone lowered as much as 40 percent. However, selecting the right fan blade is key to maximizing energy savings and air movement, measured in CFM's (cubic feet per minute).
At Galesburg Electric Lighting, we have a variety of quality-made fan blades, in a wide array of sizes & styles for your to choose from. The number of blades your fan has is purely a matter of personal choice but, for optimum performance & efficiency, you should settle for no less than blades which all match in weight & balance. Blades should, also, be made of wood or acrylic, and sealed & treated to protect against humidity.
For safety, blades should be at least 7 feet above the floor. When using a ceiling fan to cool your home, blades are most efficient when placed 8-9 feet above the floor. source: Craftmade
