A ceiling fan is a common household appliance that is attached to a ceiling and runs through its paddle in a circular motion. Through this circular motion by the process of evaporative cooling, it provided cooling.
A ceiling fan or a table fan consumes electricity and in turn, provides cooling. In the spring season, a ceiling fan is enough for a soothing effect and its cooling provides comfort. But, in mid-summer, you obviously need an AC other than a ceiling fan. In short, except for winter, a ceiling fan is used almost the whole year.
Apart from that, in terms of saving electricity, we need to look at many basic points that are neglected in real life. There are different types of fans available in the market. Some consume more power while others can not.
- The average power consumption of a ceiling fan is 31.1 W.
- There are different energy saving fans of different category like largest (84′), large (54′), medium(43′), small(19′-25′).
Ceiling Fan Use Electricity In Watts
Common ceiling fan wattage is 3.1 W. If the speed of the ceiling fan is low, it consumes 3.6 Watts, while on the stand-by ceiling fan on average consumes a power of 1.1 watts.
How Many Watts Does A Ceiling Fan Use Depending Upon Size?
Let’s compare the size and wattage of different ceiling fans at different temperatures.
Small Fan Size (36′) or less, uses on an average 4.7 watts on high speed, 4.6 on low speed 0.8 watts on stand-by, and 54 watts on average efficiency.
The overall performance of a small-sized ceiling fan is considered poor when compared to other ceiling fans.
Medium Sized Ceiling Fans (42′ to 48′) on average consume 17.9 watts on high speed, 3.5 watts on low speed, and 1 watt on standby. And the average CFM to-watt ratio is 251 watts.
Large Sized Ceiling Fans (50′-54′) on average consumes 23.4 watts on high speed, 3.6 watts on low speed, and 0.9 watts on standby while the average CFM to watt ratio is 268 watt.
The largest Sized Ceiling Fans (56′-58′) on average consume the power of 34.6 watts on high speed, 3.6 watts on low speed, and 1.1 watts on standby, while the average CFM to watt ratio is 301 watts.
Hence, proved that the larger the ceiling fans, the larger power they consume and in turn deliver the highest CFM. CFM is the amount of air the fan can move.
How To Calculate Power Consumption Of A Ceiling Fan?
Most of the users try to calculate electricity consumption in Watts. But when it comes to monthly consumption, it is calculated in kilowatt-hours. The unit used for electricity measurements is kWh. To find out the electricity consumed per month by a ceiling fan, check the below-given formula.
kWh= Ceiling Fan Wattage x Duration Of Use (hours)/1000
Consider an example.
Mr. Ali has a fan of 75 watts. The ceiling fan runs 12 hours a day. How much power will it consume in a month?
Power Consumed within day= Rayed Power x Operational Hours
Power Consumed within day =75 x12
Power Consumed within day=900 Watt Hours
Power Consumed within a month=900 watt hours x 30 30= days in a month
Power Consumed within a month=27,000 Watt Hours
Power Consumed within a month= 27 kWh
Does A Ceiling Fan Uses A Lot Of Electricity?
No, this is just a myth. The ceiling Fan does not consume a lot of electricity. It does consume electricity, but not so much. In short, a ceiling fan is capable of cooling enough during summer as compared to an air conditioner. Ceiling fans are considered an efficient device for cooling.
Ceiling fans on average consume 100 times less electricity as compared to 3.5 Kilo Watt Air conditioners. Let’s compare the average of a 1-hour running ceiling fan. This is equivalent to.
- Boiling half of an electric kettle.
- Average car battery charging.
The Energy Efficient – CFM Of A Ceiling Fan
CFM is the amount of air that a ceiling fan can move in a cubic meter. Those ceiling fans that have high CFM and consume low power for their operation are considered the most energy efficient. Those types of ceiling fans should be used for daily uses as they cost less by consuming less electricity.
According to studies, on an average ceiling fans has 287.7 CFM/W.
Hence, it is proved that a ceiling fan consumes less electricity as compared to other cooling devices. Make sure to buy ceiling fans that have a 5-star rating certified. 5- star certified rating fans consumes less electricity as compared to others. So, always check such ratings.
