How Many Watts Does a Ceiling Fan Use?

A ceiling fan is an associate energy-efficient and popular home appliance, which is hooked up to the ceiling and uses an electrical motor to rotate blades or paddles in a circular motion. But, few people barely know what the wattage of the indoor ceiling fans uses. This post covers how much power ceiling fans can use.

Why Do Watts Matter for the Ceiling Fan

All the indoor outdoor ceiling fan is rated by watts that indicates what proportion electricity the ceiling fan desires.

How Many Watts Does A Ceiling Fan Use In Various Size?

There are different sizes and styles of ceiling fans on the market. 24 inch ceiling fan, 48 inch ceiling fan, and 56 inch ceiling fan are three of the most commonly used in most families. In the following chart, I will illustrate the different watts between the different sizes of the ceiling fan.

Ceiling Fan Size Average on High Average on Low Average on Standby Average Efficiency(CFM/W)
Small-Size (36” or less ) 47W 4.6W 0.8W 54
Medium-Size (42” to 48”) 17.9W 3.5W 1.0W 251
Large-Size (50” to 54) 23.4W 3.6W 0.9W 268
The Largest Size (56”to84”) 34.6W 3.6W 1.1W 301

According to the chart, we could learn that the small ceiling fans (36’’ or less) have poor performance than the larger size of ceiling fans. They consume 47 watts on high, 4.6 watts on low, and 0.8 watts while on standby. Their average CFM per watt is 54. This result may be caused by the low market demand for the small-size ceiling fan and the lack of product development for the small-size ceiling fan.

As for the medium-size 3 blade ceiling fan, it has the lowest consumed watts among those four sizes. The average CFM to watt ratio for medium ceiling fans is also relatively lower than the large-size and the largest size of the ceiling fan. And the large decorative indoor ceiling fans consume 23.4 watts on high, 3.6 watts on low, and 0.9 watts while on standby. The average CFM to watts in large ceiling fans is 268.

In summary, this chart also indicates the watts consumed and CFM/W of the indoor ceiling fans increase, as the ceiling fan size increases.

How to Compare Electricity Usage Between Fans

Generally, all-electric ceiling fans in the United States for residential use are required to tag an EnergyGuide label. But, with the development of online shopping, most people prefer to buy the fan ceiling modern online. And, many online stores usually don’t put these labels on the product page. Therefore, when you compare the electricity usage between fans, you had better see the energy guide or consult the service staff.

How to Calculate the Wattage for Your Ceiling Fan

A simple formula is introduced to help you figure out exactly what your antique decorative ceiling fan ( or other home appliance) costs to run in a year. This formula needs you to figure out the fans’ watts and the actual cost of electricity in kilowatt-hours:

Step 1: Fan’s max watts x the hours per day you run a fan

Step 2: Convert the result of the step to kilowatt-hours. Then divide the number by 1000.

Step 3: Then, you could use the above number to multiply by 30 to know how much energy the fan uses each month.

Step 4: In this final step, you could multiply this by the cost of electricity. Then, you could clearly know what the monthly cost of the ceiling fan is.

Do Indoor Outdoor Ceiling Fan Consume A Lot of Electricity?

As a matter of fact, ceiling fans don’t consume a lot of electricity. And, compared with other home appliances, they are not regarded as energy guzzlers. As the chart indicates, the ceiling fans offer low-power cooling, with an average wattage of 31.1W (max). Combined with the high CFM per watt, ceiling fans are considered one of the most efficient devices for cooling.

Are Ceiling Fans Expensive to Run

No, the ceiling fans are inexpensive to run. In the US, to run a large (50’’ to 54’’) ceiling fan, you just spend 0.004 cents per hour on average. You may have to run the large warehouse ceiling fans for 250 hours before it costs $1. However, when comes to other electronic devices, you have to pay over $1 for running a typical 3,500W AC unit for just 2 hours. (The prices is mentioned just for reference, is not the actual current price.)

In summary, compared with other devices, such as the AC unit, ceiling fans are a cost-saving appliance.

Conclusion

All in all, the various size of the cool ceiling fans offer various wattage and spend different electricity. And, regardless of the size of the indoor ceiling fans, they all are regarded as energy-saving home appliances.

How Many Amps Does A Ceiling Fan Use?

As we all know, compared with other cooling equipment, such as AC, the ceiling fan consumes very little energy. The amperage is one of the powerful pieces of evidence. You could take try to calculate the amps of your outdoor ceiling fans or indoor ceiling fans. But, how to figure out many amps a ceiling fan uses? There are several factors that need your consideration, including the type of ceiling fan, its settings, speed, and more. In this post, let us learn some information about the amps of the ceiling fan.

How Many Amps Does A Ceiling Fan Use?

Generally, the ceiling fan uses between 0.5 amp and 1 amp on average. The used amp mainly depends on the type of fan, model, and settings. For example, the outdoor ceiling fans may use amps more than small room ceiling fans, because the outdoor ceiling fans need more electricity with their large size.

How Many 56-Inch Ceiling Fan Amps Use?

Learned from the ceiling fan amp use table, you could get the answer that is 0.85 amps on average. The following table is the author’s conclusion on the use of amps of various sizes of ceiling fans.

Ceiling fan Size(in diameter) Amps
24 inch 0.34
30 inch 0.40
36 inch 0.46
42 inch 0.54
48 inch 0.63
52 inch 0.74
56 inch 0.85
60 inch 1.00
72 inch 1.50

 

Tips: decorative ceiling fan with light may draw 2-4 times more amps. A 60-watt blub may use 0.5 amps. Therefore, if you turn on the ceiling fan and fan’s light all the time, it would raise your electric bill.

How Many Floor Standing Fan Amps Used？

On average, the floor standing fan uses between 0.3 amps to 3 amps. The consumed power would decrease as the speed of the electric stand fan gets lower.

How Many Box Fan Amps Use?

The box fan usually requires less than 1 amp to function at its best settings. For example, a standard 20 inch box fan needs only about 0.45 amps.

How Many Ceiling Fans on A 15 Amp Circuit?

From the perspective of electrical safety, a 15 amp circuit can run four 280 wattage ceiling fans without any problem. A 120 volt, 15 amp circuit can supply 1880 watts. And the 52-inch fan is between 90 and 100 watts. Then four ceiling fans at 280 watts each are about ⅔ of the total wattage that can be on the 15 amp circuit. Based on this consumed electricity condition, you also could use three 60-watt light bulbs.

How Many Ceiling Fans Can be on A 20 Amp Circuit?

The standard electric fan is between 60 and 80 watts. If you only want to install the ceiling fan, you could install 20 ceiling fans on a 20-amp circuit. Because the 20 amp circuit has a load capacity of 2400 watts, you could use a big air industrial fan and other industrial appliances such as light.

Can 2 Ceiling Fans Be on the Same Circuit?

Yes, you can. If you want to connect two fans to the same circuit and controlled by one set of switches, you just need to connect the ceiling fan’s neutral wires, their ground wires, and their hot wires in parallel.

How Are Amps And Watts Different?

The amps are the unit of current electrical flow and watts are the actual unit for power. If you multiply the amps by the voltage you get the wattage. The amps only have relations with the issue which is about electricity, but watt could stand for other forms of energy.

Conclusion

All in all, an average ceiling fan with a medium to a high setting usually needs 0.5 to 1 amp. Various factors affect the amount of the used amp, including the type of the ceiling fan, size, speed settings, etc. And ceiling fan with light may use more amps than the ceiling fans without lights.
