Ceiling Fan Power Consumption: Calculate Your Fan’s Wattage

We think you’ll agree with us when we say – having a ceiling fan is an absolute necessity in every Indian household! They bring a comfortable breeze to any room during the summer season. Not to mention, they are more affordable and energy-efficient as compared to air conditioners.

However, despite their popularity, you might not be aware of how much power a ceiling fan consumes. This is why it is important to calculate the power consumption of ceiling fans before making a purchase. If you’re confused about how you can calculate the power consumption of electric ceiling fans, we have your back! In this article, we will analyse the wattage of ceiling fans and how much power they consume.

How much Power does an Electric Ceiling Fan Consume?

On average, the electricity consumption of a ceiling fan is about 75 Watts. However, this number may vary because of the following factors.

1. Ceiling fan brand

2. Size of your ceiling fan

3. Average duration of using a ceiling fan

4. Air delivery rate

5. Speed at which the air is delivered

6. Revolutions per minute

The power demand of a ceiling fan at its greatest speed, excluding the light fixture, is measured in watts. The size and kind of motor used in the ceiling fan will determine how much power it uses. In comparison to an energy-efficient ceiling fan, a regular ceiling fan would use more energy.

Ceiling Fan Wattage Based on Size

If the electricity consumption of the ceiling fan is a deciding factor for you, and you’re looking to reduce your electricity bill, we are here to help! Below, we have listed the wattage of a ceiling fan based on its size.

How much Power does a Ceiling Fan Consume Per Hour?

Power is measured in watt and kilowatt. It essentially displays the rate at which a device consumes power. For instance, a 100-watt ceiling fan will use 100 watts of power per hour. 1000 watts equals one kilowatt.

The power consumption of a ceiling fan per hour is measured in kilowatt-hours. For instance, a 100-watt TV that runs continuously for 24 hours uses 2400-watt hours, also known as 2.4-kilowatt hours, or 2.4 units of electricity.

How much Power does a Ceiling Fan Consume Per Day?

Let’s study the power consumed by a ceiling fan in a day with the help of an example:

In your home, let’s say there is one 75-watt fan which runs for four hours during the day and eight hours at night. So, we will calculate the power consumed by this one fan:

1. Power consumed by one fan in a day = Rated power X Operational hours

2. Power consumed by one fan in a day = 75 watts X 12 hours

3. Therefore, power consumed by all 1 fans in a day is 900-watt hours 

How much Power does a Ceiling Fan Consume Per Month?

The power consumption of a ceiling fan throughout the month is calculated in the same manner. Let’s understand the same using the previous example itself: 

So, the power consumed by one 75-Watt ceiling fan is 900 Watt-hours. To obtain the monthly power consumption, we simply multiply the number by 30 days.

This means:

The power consumed by 1 fan in a month is 900 X 30

Which is 27,000 Watt-hours. When simplified into Kilowatt-hours, it becomes 27 kWh.

Power Consumption of Fans with ActivBLDC Technology

Brushless Direct-Current (BLDC) motors convert electrical energy to mechanical energy. Intelligent speed control, high torque, and low maintenance are the main characteristics of DC motors. Direct-current electricity powers a brushless direct-current motor. Instead of the electromagnets used in induction motors, permanent magnets are used in BLDC motors.

Crompton’s fans use ActivBLDC technology which lowers your electricity bills up to 50% and provides superior air delivery. Most BLDC fans are found to compromise on air delivery as they reduce power consumption. However, Crompton’s ActivBLDC fans go one step further by providing a higher air delivery in your home, while saving money on your electricity bills. 

Factors That Determine the Energy Efficiency of Ceiling Fans

You must determine the ceiling fan’s wattage in order to comprehend how much electricity it consumes. In addition, you should consider the national price of electricity in India as the second factor to determine how much it costs to run a ceiling fan each hour, day, week, or month.  

While traditional ceiling fans consume a significant amount of power, ActivBLDC fans use less power and are able to produce superior air delivery. This makes ActivBLDC fans a more cost-effective and environmentally-friendly choice for households. Activ BLDC Fans are also 5 Star rated by BEE. In the end, it’s a no-brainer: ActivBLDC fans are the clear winners when it comes to energy efficiency, so make the switch today!

FAQs

1. Do ActivBLDC Fans consume less power compared to regular fans?

ActivBLDC fans consume up to 50% less power as compared to regular fans. Crompton uses ActivBLDC technology which reduces power consumption without any compromise on air delivery.

2. How many units of electricity are consumed by fans per day?

An average ceiling fan consumes approximately 75 watts of electricity. This may vary according to the brand, size of the fan, and several other factors.

3. Does fan speed affect electricity consumption?

Yes, the fan motor consumes less electricity at a slower speed. Inserted resistance reduces the voltage available to the fan motor.

4. How much does a ceiling fan cost to run?

The electricity cost of a ceiling fan depends upon the ceiling fan’s wattage and the price of electricity. Using these two factors, you can determine the amount of your electricity bill.
