The impact of your ceiling fan blade angle on your electricity bill


Living in a tropical country often takes a toll on our electricity bills. From air conditioners to water coolers, there are a number of home appliances used in an urban household that help us keep our homes cool in summer. One such appliance which is an integral part of every home’s cooling system is the humble ceiling fan. Though a ceiling fan takes up an average of 60 watts of current, even on high speed, you can reduce your electricity consumption even further by taking a closer look at your ceiling fan’s blade angle. Read on to know more.

How does a ceiling fan work?

A ceiling fan works with a simple motor that runs on electricity and rotates the blades attached to it. The blades are designed in a preset fan blade angle setting that pushes the air down during a high-speed movement. If the blades are flat, like the wings of an airplane, they will simply glide through the air without a throw. Similarly, if the blades are inclined, like the angles of an oar while rowing a boat, the throw will be higher. Keeping this in mind, all branded fans are designed with an optimal ceiling fan blade angle of 7 to 10 degrees for good circulation of breeze in the room.

What happens when the ceiling fan blade angle is altered?

When the ceiling fan’s blade angle changes, it pushes down more air than usual due to the higher resistance created. Though this may sound like a good idea to get a higher throw of air, an altered fan blade angle setting will take a toll on the connection and wiring. Additionally, it can also lead to a noisy fan which can be displeasing. However, the biggest consequence of an altered ceiling fan blade angle is the increased electricity it will consume due to the higher air resistance.

How to keep your electricity consumption low?

It is best to leave your fan untouched for optimal performance and uniform current consumption. Following are a few additional tips to consider that reduce the impact of your ceiling fan blade angle on your electricity bill:

  • Be very careful while cleaning your ceiling fan. Use a high stool to reach the blades, so you do not have to bend them down to get to the corners. Bent blades not only alter the aesthetic appeal of the room but they also take a toll on your electricity bill.
  • Do not mix up the blades of your ceiling fan. A lot of us indulge in fan installation hacks and mix up the motor of a fan with the blades of another. This may change the ceiling fan blade angle and have a huge impact on your current consumption.
  • It is a good idea to set your fan in the counterclockwise direction during hot summers and vice versa during winters. When a fan runs counterclockwise, it pushes air down at the center of the room creating the effect of a cool breeze. Similarly, when it is set in clockwise, it pushes air to the edges of the room, creating a uniform temperature. You can find the reset button near the motor of the fan. Resetting the direction of the fan helps in ideal performance with uniform current consumption.
  • Last but not least, it is always a good idea to turn the fan off when it is not in use.

Now that you know how your fan blade angle setting impacts your electricity bill, make sure you opt for a high-performance Finolex fans and get the right size fan for your room. You can also read our blog on tips for choosing the perfect fan for more insights.
