Ambit Energy Reviews: Ceiling Fan Efficiency
Posted by: Anna | 07/25/2017 at 09:00 AM
While they make your home more energy efficient, ceiling fans are not the sexiest product to research and choose. To make things easier, fans now have labels telling you how much air is moved for each watt of energy used. Airflow for fans is measured in cubic feet per minute. Most ceiling fan packages show a box with three numbers: airflow (cfm), rate of electricity use (watts) and airflow efficiency (cfm/watt).
Here are a few specific tips to help with your fan hunting:
- Efficiency Increases with size - Without getting into complex physics, a bigger fan blade is more efficient, all other things being equal. Therefore, buy the biggest fan that makes sense for the space. The 52-inch size is very common, but may not be the right fit for your room. Generally, you’re better off going one size up from the normal recommendations for a room size.
- Use the Energy Star Website Guide - The Energy Star website has a great fan product finder with a ton of options to help you select the right fan for you. There are many manufacturers listed, including the racy sounding Big Ass Fans. The company makes fans for many industrial applications and warehouses. They also make the Haiku line for residential uses. Hunter Fans and Westinghouse may have the most brand visibility to the average consumer, but visibility doesn’t always mean they are the best options although both produce strong lines of ceiling fans.
- Turn your Fans Off - Remember your parents yelling at you to turn off the lights when you left the room because electricity costs money? Turns out they were right. Turning off the lights and fans in rooms helps save energy. Fans are meant to cool you with moving air, rather than cooling the room in general like an air conditioner. Running a ceiling fan in an empty room is only wasting electricity.
- Clean your Ceiling Fans - Fan blades gather dust. If your fan looks like an overhead dust bunny colony, take a few minutes to clean the blades. It helps the dust from recirculating around the room and getting sucked into the air conditioner filter. It also allows you to use the fan on a higher speed setting without sending dust clumps all over. Also, food and beverages tend to taste about 50 percent better without a sidecar of dust clumps.
- Balancing your Ceiling Fans - Most folks have experienced the wobbly ceiling fan that kept you awake or made you worry it was going to work itself loose one day and fall down while you were under it. There is a simple cure for this. Most fans come with balancing kits to help even out differing blade weights. If your fan does wobbles, you can contact the manufacturer to get a kit to even things out. You’ll get instructions for how to determine the lightest blade, and then the weights usually stick right on with an adhesive backing.
