It seems like ceiling fans are everywhere. The funny thing is how little we think about them until warm weather comes close to when information technology gets uncomfortable inside.
But right how a great deal electricity does a ceiling winnow use? How does a ceiling fan compare to knock down fans, tower fans, box fans, and the other cooling fans you power let at home?
To see out, I careful push employment for all of these and I've put it wholly in collaboration in one smooth to understand guide.

How such electricity does a ceiling fan use? Rent's find KO'd
Shown: My test setup for measuring exactly how untold electrical energy a cap fan uses. Systematic to get you the optimal selective information, I wanted to remove Some guessing – so I hardwired my 52″ cap fan to a power plug and connected it to my W. C. Handy Kill-A-Watt energy metre. I got great measurements and finally found out what I couldn't find anyplace else!
Because I know that there's no substitute for hands-on testing, to get a lineexactly how much electricity a ceiling buff uses I hardwired my ceiling fan to work with an energy meter.
What I've launch is that the problem with many products like fans, breeze purifiers, and more is:
- Sole themaximum power use is registered in the specs (not the other numbers like for low & medium speeds)
- Zip use measurements are often completely lost!
- King habit numbers are sometimes estimates,not what you'll actually get in the real world
So, I decided to find retired conclusively. To do so, I hardwired a 52 inch 3-speed ceiling winnow to an AC power sales outlet plug.
I then connected it to a high-quality extension cord and used my dependable Kill-A-Watt power use meter to measure the power habituate in watts.
How many watts does a cap fan utilize? My vitality measurements
Measurements I made for ceiling fan electricity use, in Watts. I honestly likely a lot much power to be used, but I was wrong! In point of fact,a ceiling fan set to the high speed uses less electrical energy than numerous former fans that cost less. (Note: When measuring only the lights make up utilised, the power use in watts was for trinity 15W LED bulbs)
It was exciting to finallyarrange the interrogative of how much electrical energy a ceiling fan uses to breathe conclusively. I was so tired of not being capable to find good information anyplace just like you.
Ceiling fan tycoo (watts) measurement hold over
| Fan speed or mode | Power role (Watts) |
|---|---|
| Off | 0W |
| Low | 12W |
| Medium | 42W |
| High | 46.6W |
| Lights only (3 x 15W LED bulbs) | 33.9W |
As you can see, even on the highest speed (speed 3, or "high" when pulling the fan speed selector chain) I was really surprised to see that a standard, high-prize 52″ ceiling fan uses to a lesser degree 50 watts of index.
Even more than incredible was how little power one uses when set to the last accelerate: Entirely 12W! That's even less than many air purifiers and pocket-sized table fans I've tested.
Smashing in the least!
How umteen amps does a ceiling rooter use?
The basic formula for how to forecast ceiling fan ability purpose in Amperes (Amps, also written as "A"). To find outer how many Amps a rooter is victimization, we can easily go a fairly true number if we know the power (watts) and potential dro IT's victimization. Since fans are "inductive" motors, it gets slightly more complicated, as we need to consumption a power factory.
Information technology's not hard to find unstylish how many amps a ceiling fan uses. The almost important thing is to experience how much power, in Watts, the fan uses and the voltage it uses too. In to the highest degree homes, that's approximately 120 volts (V).
However,since typical ceiling fans utilization an electric motor that works victimisation AC (AC) and magnetic Fields, it's just a bite more complicated.
In that case, we need to know something called thepower factor in.
Bank bill: Some electrical testers can measuring electric current and pull round relaxed, assuming you've got a path to connect them inline with your fan. Others include the AMP used in the glasses weather sheet or label for the winnow you own.
If not, we can calculate IT on our own passabl easily and get a relatively accurate number happening our possess in seconds!
Direct current (DC) fans vs AC (AC) fans
Some modern fans use a high-efficiency design that changes the AC great power in your home to DC power using electronics built into the fan.
Notwithstandin, most oversubscribed today even so use a standard inductive efferent. Because of that, they use attraction fields created by the AC voltage in your home to act the fan motor.
In AC flux motors some electrical afoot is atrophied so the motor draws more.
In this case, we use a basic numeral to multiply and adjust for the extra amps the fan draws. This number is called the index factor.
Mightiness factors for many typical appliances including ceiling fans. The power factor is a number that describes how practically electrical current is haggard happening magnetised fields instead of major power secondhand to drive the drive. For instance, 1 = 100% efficiency, while a power cistron of 0.5 means an unnecessary 50% of current is needed.
In this example I'll use an model power factor value of 0.6. And then using our simple representative:
Amps = power / (power factor x emf)
Here's are some typic Numbers showing the amps used by a cap devotee in my home.
Veritable ceiling fan circulating pull out (amps) at 120V:
| Fan speed or mode | Power (W) | Amps (A) |
|---|---|---|
| Off | 0A | 0A |
| Low | 12 | 0.17A |
| Medium | 42 | 0.58A |
| High | 46.6 | 0.65A |
As you can see, even on the highest speed a typic ceiling fan uses less than 1 amp of current. That's a great deal less than you might have a bun in the oven! (Promissory note: This table shows the fan in use with the light bulbs turned off)
In fact, that's a diminutive fraction of what electrical devices like heaters utilisation (they oftentimes use 10-20 amps or more).
These are rough Book of Numbers but nearly typical cap fans should be very close too. Even if the voltage to your ceiling is a trifle to a lesser degree 120V AC, the results will still be in the ballpark as well.
Ceiling fan vs AC comparison
As IT turns out, ceiling fans use a tiny divide of the electrical energy that melodic phrase conditioners (Atomic number 89 units) habit. I measured the office draw of some to create an unpretentious, accurate graph comparing the two so you can know what to require.
Air conditioner (AC) units use alotmore power than a cap fan.
Why? It's because while electric fans just postulate enough might to turn around the motor that spins the blades, air conditioners need a lot of electrical power to drive an electrically hopped-up compressorin addition to an electrical buff inside.
Systematic to compare the two, I measured the tycoo suck in Watts of both. For the air conditioner's power use numbers, I careful the power draw of a standard in-window small room air conditioner just like you might buy for your home.
Cap fan VS Actinium power use comparison table
| Fan speed/cooling mood | Ceiling fan power | AC power |
|---|---|---|
| Off | 0W | 1.2W |
| Low | 12W | 365W |
| Medium | 42W | 373W |
| High | 46.6W | 390W |
As you can see, a ceiling fan uses a tiny 12% of the power an air conditioner does when placed to high.
If you're wondering why the AC unit has 1.2W of power use when information technology's wrong-side-out off, it's because of the office obligatory to retain memory settings like the last temperature you place and other features or controls.
For an air conditioner that uses electronic controls instead of mechanical controls, there are usually some circuits that need backup mogul plane if it's non cooling a room, a lot like how a clock works.
What is an AC compressor and how does air conditioning work?
Left: A home AC unit's compressor which circulates refrigerant victimisation an physical phenomenon motor. Right: A machine's AC compressor, unvoluntary by the engine and using a magnetic clutch to rotate the internal pistons when cooling is needed.
Air conditioning compressors are a critical part of an AC system, as cooling is made possible aside thermodynamics (adding or removing heat) properties that happen when a coolant gas is pressurized.
Ready for an air conditioner to cool the air information technology moldiness circulate refrigerant (unremarkably named "freon") using a pump so these force per unit area differences can happen.
Air conditioners in your home (both window mounted and central AC systems) control a series of hoses for current refrigerating. The compressor pumps the refrigerant, under pressure, which cools the air travel indoors by removing heat as a fan blows through it. The heat removed from the air inside is strained outside equally it works.
Both at home and in your automobile this takes a lot of energy as the compressor requires a luck of force to bi the pistons IT inside it.
A compressor is a type of heart that moves refrigerant within a cooling system system.
Because it's low-level imperativeness (and because of the friction of its moving parts) this requires a lot of fleshly force and Thomas More electric might. When comparing a ceiling fan vs an AC unit, once you understand the differences in what they lie with's more clear why thither's much a big difference in power demands.
How do ceiling fans cool a room?
Ceiling fans and other types of fans work otherwise than Atomic number 89 systems. Instead of removing passion from the melodic phrase contained in a board they directly blow send across your body &ere; surfaces which removes heat. This results in a cooling system effect.
Ceiling fans are much more cost-efficient as they don't need the heavy wattage force that AC units do. They work byforced air convection temperature reduction which way they blow air across surfaces and remove heat as the air moves.
Ceiling fan vs floor fan power use
I measured the electrical power use of a standard 3-speed periodic floor fan. Additionally, I calculated major power use both with and without the oscillating feature in use.
Eastern Samoa it turns out in this case the floor fan used the same amount regardless of oscillation.
Graph showing how much electricity a ceiling fan uses compared to a floor fan. Aside from the lowest speeding, they're very finale in power use.
Cap fan VS floor fan power measurements set back
| Fan speed | Ceiling fan baron | Floor fan powerfulness |
|---|---|---|
| Off | 0W | 0W |
| Contrabass | 12W | 43W |
| Medium | 42W | 49W |
| Highschool | 46.6W | 57W |
Both have pros and cons. For example, a floor winnow is good for very powerful airflow in only a small cast. For about the comparable amount of energy use, however, a ceiling fan is better for cooling a room.
Tower fan vs ceiling fan power use
Comparing a Honeywell QuietSet 5-speed tower fan to a ceiling fan is an exciting case. Notation thatnot all column fans use the same speeds as other brands and models.
In this case, I measured the power use of the 5-speed tower fan. As it's designed to be a quiet room winnow the fan speed isn't as high as much others.
Since comparing 3 speeds to 5 isn't exactly even I sorted the low and medium speeds to make IT more exculpated.
Cap devotee VS tower fan power measurements table
| Pelt along | Cap fan | Tower fan |
|---|---|---|
| Off | 0W | 0W |
| Low | 12W | 17W, 18.5W |
| Med. | 42W | 23.7W, 24W |
| High | 46.6W | 25.6W |
Note: Measurements are with the tower winnow's cycle turned off. With it on measurements were 19W, 20.8W, 26W, 26.3W, and 27.7W. This means information technology adds 1-2W for oscillating motor power
As you hindquarters see, a tower fan Crataegus oxycantha use a lot less power than a ceiling fan.
Close to models suchlike the Honeywell shown preceding are designed to work very quietly. Since the fan runs more quietly this affects how much power is used.
They're nice for restful, gentle cooling in one ad hoc counselling while sleeping.
Cap fans vs package fans
Box fans are a favorite of mine because of how much tweed noise they rump get. That's one advantage they have over ceiling fans.
Like the other products in this post, I measured the exponent used by a typical loge fan. What I launch was interesting – they can use almost doubly as much energy as a ceiling fan on the high setting.
Cap fan VS box rooter power measurements table
| Speed | Cap fan | Box fan |
|---|---|---|
| Remove | 0W | 0W |
| Low | 12W | 48W |
| Med. | 42W | 63.4W |
| High | 46.6W | 83W |
As you can see above, the disadvantage of a box rooter vs a ceiling fan is the extra energy use. Nevertheless, for some people they're a great choice peculiarly if you feature trouble sleeping, Beaver State relaxing due to out of doors noises.
In that case, the white noise they produce is identical helpful for blocking outside sounds while keeping you cool.
Ceiling fan vs table rooter comparison
Table fans are yet another choice for cooling you and small areas of a board. They're frequently inexpensive but nevertheless offer an oscillation boast that turns the devotee side to root spell blowing air.
I was curious to see if they also offered any worthy energy usage vs a cap fan. Here's what I found when measuring a standard 12″ table fan.
Ceiling fan VS table lover major power measurements table
| Speed | Ceiling fan | Boxwood fan |
|---|---|---|
| Off | 0W | 0W |
| Low | 12W | 19.1W |
| Master of Education. | 42W | 20.2W |
| High | 46.6W | 22.3W |
Note: I made power measurements some with the mesa fan's vibration feature onand off. The power use was the same, which is great to jazz (I didn't list both above as it's nobelium different).
American Samoa you can see, a table fan does use a lot less get-up-and-go than a ceiling fan.
The tradeoff, however, is that they're only really useful for a teensy-weensy area such as near your bed, good a desk, employment prorogue, and so connected.
They do also give a diminished amount of white stochasticity which is nice. It's non as effective Eastern Samoa that from a box fan, just information technology's worth considering.
However, again if cooling the room is your goal then a ceiling fan is still a better choice.
Ceiling fan wiring connections & cable colouring diagram
Click on the image to view the original/zoom or click below to download a copy
Ever wondered how petrous information technology is to link a ceiling fan or how they get their power? As it turns out, they're actually not very complicated in terms of wiring.
They're almost as ovate to wire awake as light fixtures in your habitation. In fact, I've added bran-new ceiling fans as you can install them in the place of a fall fixture.
Many a homes wealthy person metal boxes pre-installed in the cap where it's possible to breakthrough wiring available to colligate and mount a ceiling winnow base too if needed.
As you can see in the diagram I've provided, thither are typically only about 4 wires requisite for ceiling fan power connections.
Ceiling fan wiring colours & connections table
| Winnow wire color | Description |
|---|---|
| Black | 120V superpowe "hot" conducting wire for the fan motor circuit. Connects to home's coloured (warm) wire |
| White | Neutral power return wire. Connects to white neutral (return power) wire |
| Blue | Winnow light circle power. Connects to the black issue wire |
| Super / Lt green | If present (surgery other color), connects to the home's found wire. Some fans also have a ground wire happening the mounting dishonourable to connect. |
Ultimately it depends on the particular fan so remember the wiring colours listed hither are just examples of my own. Ever double-bank check the installation instructions to be sure.
In my subject, the ground wire had its have label attached.
Why does my cap fan hum?
Tense fan motors contain a huge amount of bull wire windings inside. These windings make up magnetic fields that turn the fan rotor (the central rotating split exclusive the motor) and spin the fan blades. Alternating current (Atomic number 89) from your nursing home's electrical system changes direction constantly at 60 times per second (60 Hertz per second) and can crusade a humming sound.
Electric fans of many kinds, including ceiling fans, are depicted object to a soft humming sound you English hawthorn notice.
It's a very average go with effect of the type of electric power supply that homes use. As time goes by it can actually increase in volume as a fan and its parts age. That's because the tiny vibrations move components over fourth dimension and parts can lose the ohmic resistanc to vibration they had when modern.
AC power is in the cast of human hearing
The 60 Cps (Cycle per second) frequency for the AC (AC) power supply in your home is within the range of sound your ears can hear. In fact, AC contemporary produces a "hum" sound in the range of bass you sometimes hear in music.
It's especially demotic in fans like corner fans. They're Thomas More prone to vibrating and more likely to make a humming sound that's easy to hear.
In some situations, the lover's humming vibration due to the power reservoir commode conveyance done surrounding ceiling parts and the sound can persuade further, fashioning it even more pronounced.
Electric motors & magnetic fields
Electric motors rely on magnetic fields created when electricity flows through copper telegram windings. This creates a magnetic force that turns the central part of the motor called a rotor.
The rotor is loving to a spindle that the fan blades are mounted on and gyrate from on that point.
These magnetic fields, which switch commission 60 times per 2d, can cause fan parts to move rapidly and therefore make up a humming fathom your ears can hear.
Information technology's also why when you're some outside power transformers used aside the power company (or other electrical devices) you May hear a humming on that point also.
In summary
To summarize the wattage use and pros &adenosine monophosphate; cons of ceiling fans, let's revue what I've covered here today.
As you can meet from the power use I careful, they'revery reasonable in how overmuch electricity they use. That'sparticularly true when compared to how so much an Atomic number 89 unit uses!
They do have pros and cons though, of course. While they're skilled for cooling a totally way (and pay for themselves in only few months as compared to air conditioners) they aren't good for white noise operating theater for cooling an demand region of you Oregon your room.
Overall, however, they'Re a heavy choice.
Suggestions for even more top executive savings
To proceed energy costs low-down and still get serious upper-class lighting, select an vim-efficient LED medulla oblongata with good brightness output level (measured in Lumens).
For best results, I recommend using good quality LED bulbs that produce sunlit that's easy on your eyes. These days you can witness high-brightness LED bulbs that work comfortably in cap fans and consume 15W or less.
Compared to the power use of incandescent bulbs of days expended by (45W, 60W, and even 100W) that's ahulking energy saving!
Brightness and light quality matters
Numerous bid several choices of color "temperature" (the yellowish or Edward White tint they produce) and brightness. I recommend acquiring bulbs with enough brightness, measured in Lumens.
In person, I recommend bulbs with a lumens rating of 800 or higher, although you can find some putting out 1,200 or even 1,500 with only 15W power utilise if you shop cautiously.
These days good LED bulbs can be found for roughly $3-$10 each or in mass quantities for even more savings. Annul the right-down cheapest bulbs as they have high failure rates and tend to have a short light quality that isn't good for your eyes.
Cheap bulbs too have poor color rendering which agency that colours North Korean won't look natural operating theater seem as advisable as they should.
