How Many Watts Does a Fan Use? (7 Fan Types Examined)

Right now, we are at the beginning of the month of March. We are just starting to feel warmer days and relief from the winter. Some days are cooler and some almost summer like. But windy to be sure.

This is about the time of the year people began to pull out the fans.

In our house, We have fans in every room, except the kitchen and the bathrooms.

We have a ceiling fan in every bedroom and in the living room, that stays on constantly. And in the master bedroom there is two tower fans on each side of the bed that run almost all year long.

You would think with all the fans running that we must be using a ton of energy and our electric bill is outrageous.

But comparably, when you look at the wattage of an average fan which is usually around a 100 w and compare it to say a space heater that uses up to 1500 w on high, the difference is quite striking.

40 w up to 120 w is the average.

How much does it cost to run a 120 w fan 24 hours a day?

23 cents a day or 7 dollars a month.
$3.50 if you only run it at night for the entire month.

But that is a estimate based on the average price per kilowatt hour in the United States per state. Which is 12.8 cents per kilowatt hour.

Those numbers can vary greatly if you live in say Hawaii. Where the price per kilowatt hour is 29.14 cents. Which means the cost to run a 120 watt fan for 24 hours in the aloha state is more like 83 cents a day and $26 a month.

You can figure out how much energy any of your appliances use by using a simple formula.

Watts x Hours(used) ÷1000 x cents per kilowatt hour

How do you position a fan to get the best out of it?

How you position the fan and where you put it can make all the difference in how effective a fan is regardless of the wattage that it is using.

In the springtime, putting a box fan in the window and blowing the cool air from the outside into the inside is a great way to cool the house off. The humming of the fan also has the unintended effect of discouraging insects from coming through the window.

Placing a fan where it can easily pull in air is the trick to getting the air moving. Many times people will want to place a fan closer to the wall or the drapes to get it out of the middle of the room, but that has the effect of limiting the amount of air that can move through the fan. Thus the fan should always be in an open area where air can easily enter it.

Keeping the fan clean is also a easy way to get a lot better effectiveness out of it.

Though you will not find this problem with the ceiling fan, every other type of fan has a tendency to gather dust and Lent on the back grill. If the dirt and dust are allowed to get thick enough, they will keep air from flowing through the fan.
By cleaning the grime and dust off the back of a fan, you will be amazed at how well that old fan works.

Most of time you view a fan as a way to cool off the air inside of a room or inside of a computer, etc.

But a fan is simply a way to move air from one place to another and can be used to move the warm air from the ceiling down by simply switching the direction of the ceiling fan from counterclockwise to clockwise.

This works because as you know, heat rises.
By reversing the direction of the blades you can pull the heat from the ceiling into the room.
