Are you planning to buy new fans for your home or office? Or are you just curious to know about how much electricity do you think your fan consumes per hour? We often neglect the fans and try saving on the lights. But the crucial point that most of us miss is that even fans contribute a major portion to your electricity bills.
Here we are with this article that will educate you on the power utilization by the fan. It will help you with how to calculate the amount of power used by your fan. We will also learn how to save on the electricity bills.
Let us get started to know how much power your fan uses.
How Much Electricity Does A Fan Use?
If you want to know how much power your ceiling fan consumes, you should consider the wattage. It is the deciding factor for electricity consumption. The rated power of most ceiling fans falls under the range of 60 -100 watts.
If you want to get the specific wattage for your ceiling fan, you can find the number mentioned in the user manual. Or, you may even find it in the specifications given on the package. Here is another thing you can do. You can google search for the rated power by typing your model and the brand. It will display the exact number of watts your ceiling fan model consumes in the results.
Let us dive deeper into the topic and learn about some key terms like watts, kilowatts, and kilowatt-hours.
I am sure you are aware of the units of electricity – watt and kilowatt. 1 kilowatt equals 1000 watts. Let us say you have a fan with 75 watts power rate. That said, it will consume energy 75 watts per hour.
Usually, we calculate electricity bills in kilowatt-hours. It means the energy consumed by any device per hour. Before we learn who to calculate the power consumed by a fan, let us take a look at the below example:
Let us consider two ceiling fans at your home with a rated power of 70 watts and 60 watts, respectively. Let us assume that these fans run for at least eight hours during the day and 12 hours during the night. Let us now try to calculate the power consumption from these fans, and what would be the electricity bill you will be paying at the end of the month:
Total number of hours each fan runs every day= 20
Power Consumed by the First Fan:
Power Consumed by the Second Fan:
What’s the Bill you Need to Pay for Using your Fan?
The electricity cost for operating your fan is mainly dependent on where you live. The tariff charges per unit for electricity are different for different places. While some have the tariff charge of Rs. 4 per unit, other majority areas in India have it as Rs. 8 or more per kWh.
Let us say the electricity tariff in your area is Rs. 10 per kWh. Here is how much you will have to pay per month:
The electricity bill you can expect is 78kWh*Rs10/kWh = Rs.780
|OPERATIONAL HOURS||POWER CONSUMED BY A 70-WATT FAN||ELECTRICITY BILL (RS)|
|1 hour||70 X 1 = 70-watt hour||0.070 X 10 = Rs 0.70|
|12 hours in a day||70 X 12 = 840watt hour||0.8 X 10 = Rs 8.0|
|12 X 30 = 360 hours in a month||70 X 360 = 25-kilowatt hour||25 X 10 = Rs 250|
Rs. 250 per month is the charge of one fan. So, for three fans, it’ll be 250*3 = Rs.750.
How Much Power a Pedestal Fan or Table Fan Use?
Pedestal fans consume less power when compared to ceiling fans. It is primarily because of the pedestal fan blades and their smaller radius. We all know that the pedestal fans have a radius of about 16 inches. Moreover, these appliances are portable. Since they stand on a vertical rod, they are capable of delivering a better airflow than the ceiling fans.
Let us have a look at the rated power of the pedestal fans, which come somewhere between 50-60 watts. Since pedestal fans offer a high number of revolutions, they tend to consume the mentioned power. Some models from the pedestal models come mounted on the rod, whereas some come with a rod and stand, as well.
If we talk about the table fans, they are similar to the pedestal fans, except that they do not have a vertical rod. Most of the table fans widely used today have blades of the same size as their pedestal counterparts. You can directly mount these fans on the wall, or you can use them normally by placing them on the table.
If we consider the power rating, it is the same for both pedestal and table fans. It is around 50 watts to 60 watts.
Do you want to calculate the power consumed by either a pedestal fan or a table fan? You can follow the same method, as mentioned above.
|OPERATIONAL HOURS||POWER CONSUMED BY A 60-WATT PEDESTAL FAN||ELECTRICITY BILL (RS)|
|1 hour||60 X 1 = 60-watt hour||0.060 X 10 = Rs 0.60|
|10 hours in a day||60 X 10 = 600watt hour||0.6 X 10 = Rs 6.0|
|10 X 30 = 300 hours in a month||60 X 300 = 18-kilowatt hour||18 X 10 = Rs 180|
How To Save On the Electricity Bills When Using A Fan?
If you want to save electricity consumption when using a fan, here are some tips to follow:
- We recommend buying energy-efficient fans with a nice BEE energy star rating. These fans have an energy efficiency of about 15% more than conventional fans.
- When purchasing fans, look for the ones having brushless DC motor or BLDC motor. The significant feature of such fans is that they consume energy less than 30 watts, yet deliver the same airflow.
- Always switch off the fan when not in use. It is an essential thing that we often tend to neglect. It applies to other electronic devices, as well.
- To help cool air circulated in the room, you can use cold towels in the windows.
- Keep your windows open when using your fan. This will make sure that the room gets proper ventilation.
- The effective functioning of the fan has a direct impact on electricity consumption. If your device is not functioning properly, it will consume more power than usual. It is advisable to have your fan checked to ensure it is working properly.
