A person who wants to buy a fan wants to know about the wattage, efficiency, and cost to run a fan. so this article is all about the fan wattage, the efficiency of a fan, what it cost to run a fan, and the comparison of the fan with other types of fans.
What is the wattage of a fan?
On average the fan wattage is 39.3w and the lowest fan wattage of 6.9 watts. But the most common fan wattage is 33 watts.
The amount of wats that a fan consumes depends upon various factors like the size of the fan and the type of fan. The following table describes the fan wattage of different types of fans.
| Fan type | Average fan wattage on maximum | Average fan wattage on low | Most common fan wattage | The highest fan wattage recorded | Lowest fan wattage recording |
| Ceiling fan | 31.1 watts | 3.6 watts | 33 watts | 99.8 watts | 1.7 watts |
| Box fan | 73 watts | 47.3 watts | 100 watts | 220 watts | 5 watts |
| Tower fan | 56.5 watts | 44 watts | 54 watts | 110 watts | 6 watts |
| Table fan | 42.5 watts | 17 watts | 40 watts | 110 watts | 1.1 watts |
| All | 3 9.3 watts | 6.9 watts | 33 watts | 220 watts | 1.1 watts |
So the ceiling fan has the lowest fan wattage then it is the table fan. And box fans have the highest average wattage.
What is the electricity consumption of a fan?
A kWh is the measurement done for measuring electricity it can also be called a unit of electricity which means the number of kilowatts the electricity is consumed over a period of time.
The following table explains the electricity consumption by different types of fans in one hour.
| Fan type | Average kWh in 1 hour on Maximo | Average kWh in one hour on low | The most common kWh for 1-hour | Highest kWh recorded for 1 hour | Lowest kWh recorded for 1-hour |
| Ceiling fan | 0.0311 kWh | 0.0036 kWh | 0.033 kWh | 0.0998 kWh | 0.0017 kWh |
| Box fan | 0.073 kWh | 0.0473 kWh | 0.01 kWh | 0.0220 kWh | 0.005 kWh |
| Tower fan | 0.0565 kWh | 0.044 kWh | .054 kWh | 0.0110 kWh | 0.006 kWh |
| Table or standing fan | 0.0425 kWh | 0.017 kWh | 0.040 kWh | 0.0110 kWh | 0.0011 kWh |
| All | 0.0393 kWh | 0.0069 kWh | 0.033 kWh | 0.0220 kWh | 0.0011 kWh |
The electricity used by the fan over various durations:
The electricity used on average by a fan is 0.0393 kWh per hour, 0.3144 kWh per night, 0.0943 kWh per week when it is run for 24 hours, and 28.3 kWh per month when it is used for 24 hours.
The following table explains the electricity consumption of a running fan used at various durations:
| Fan type | Per hours | Per night used for 8 hours | per day used for 24 hours | per week used 24/ 7 | Per month used 24/7 |
| Ceiling fan | 0.0311 kWh | 0.2488 kWh | 0.7464 kWh | 5.225 kWh | 22.39 kWh |
| Box fan | 0.073 kWh | 0.584 kWh | 1.752 kWh | 12.264 kWh | 52.56 kWh |
| Tower fan | 0.0565 kWh | 0.452 kWh | 1.356 kWh | 9.492 kWh | 40.68 kWh |
| Table or standing fan | 0.0425 kWh | 0.34 kWh | 1.02 kWh | 7.14 kWh | 30.6 kWh |
| All | 0.0393 kWh | 0.3144 kWh | 0.9432 kWh | 6.602 kWh | 28.30 kWh |
What is the cost to run a Fan?
The cost of running a fan on average is up to 0.0059 cents per hour, 0.047 cents when a fan is run over a night, 14 cents per day, $0 0.99 per week, and $4.25 per month when it is used 24/7 hours.
The following table explains the cost of a running fan of different types on various time duration but using 15 cents per kWh.
| Fan type | Per hour | Per night used for 8 hours | per day used for 24 hours | per week used 24/7 | Per month used 24/7 |
| Ceiling fan | $0.0047 | $0.037 | $0.11 | $0.78 | $3.36 |
| Box fan | $0.0110 | $0.088 | $0.26 | $1.84 | $7.88 |
| Tower fan | $0.0085 | $0.068 | $0.20 | $1.42 | $6.10 |
| Table or standing fan | $0.0064 | $0.051 | $0.15 | $1.07 | $4.59 |
| All | $0.0059 | $0.047 | $0.14 | $0.99 | $4.24 |
What is fan CFM and efficiency?
A CFM of a fan refers to the amount of air in cubic feet per minute of the fan that can move in it. A fan who is having higher CFM will be able to move more in the air thus it will be effective to cool the temperature. And the amount of air a fan is able to move for each watt that it consumes is the energy efficiency indicator. The Following are the CFM result:
- The fan having the highest CFM per vote is the ceiling fan.
- At the second position is the box fan with 1750 CFM for watts and having the higher average voltage.
- The table or standing fan has a CFM per watt of 1672 which is lower than the average box band CFM.
Conclusion:
In the end, it can be concluded that ceiling fans are the most efficient fan type, and they can move fast air per watt. After the ceiling fan, box fans are the most efficient fan type preferable for personal cooling, and the average cost spent on a running fan is approximately $0.0059 per hour.
Talking about the Website, I was Very Fond of Electronics from a very small age and my love for it grew as time passed. I then Opted for Electronics as a subject in the College along with Research on my own.
I then decided to share my Gathered Knowledge with you guys, So that it can help you too for Making Decisions and Solving Problems.
