11 Myths Nearly Ceiling Fans Busted
Ceiling fans, in i form or another, take been around for over a hundred years. Some people love them patch others don’t. Where differences in opinions exist, many theories abound to justify beliefs that, whether truthful or non, sometimes become urban legends. So, let’second bust more or less of the more than mutual myths!
Ceiling fan myths:
- They cool a room
- Winter manner warms a room
- They are outdated
- They are costly to work
- They shouldn’t be operate with air conditioning
- More blades are better
- Blades decapitate people
- They are unsafe
- Putting them outdoors is pointless
- Fan-rated junction boxes are always required
- Direct attachment to joists is necessary
one. Ceiling Fans Can Cool a Room
Ceiling fans are non able to cool a room downwards. They make non own a system that actively removes thermal free energy from the air. Ceiling fans simply act the air around the room inwards a item style.
This can assist to even out the temperature in the room by eliminating pockets of colder or warmer air, but they do not change the overall temperature in the room.
Instead, ceiling fans cool people (too pets). They make this past blowing air over our peel.
When the moving air passes over pare, the naturally-occurring, insulating layer of warm air sitting against the pare is removed. The trunk volition unloose more heat every bit a response. This, likewise, is blown away too our bodies cool downward.
This is called air current chill together with it way that the cooling machinery of ceiling fans is entirely subject on the presence of occupants. Leaving a fan on inwards an empty room won’t go far colder for yous when yous go in the room later on.
2. Ceiling Fans Are Effective in Winter Mode
Most ceiling fans are fitted amongst a wintertime way setting equally criterion. This setting allows the fan to plough in the contrary direction during the wintertime or colder months.
Winter manner reverses the normal airflow inwards the room, blowing air upward against the ceiling instead of blowing air from the elevation downwardly onto the room’sec occupants.
Ceiling fan manufacturers claim that this has the power to brand a room feel warmer past displacing the warm air that gathers at the ceiling in addition to distributing it throughout the occupied space.
Now, they for sure can terminate together with redistribute this warm air. However, in that location are distinct limitations every bit to how much of an result this has on the temperature of the room.
Remember from the previous section that ceiling fans on their ain tin’t alter the temperature of a room. In wintertime fashion, they are likewise merely eliminating pockets of hotter in addition to colder air in addition to creating a more even distribution of the rut.
The sum of oestrus that gathers at the ceiling, or rather the disparity of temperatures between the air hither in addition to the air lower down inward the room is not going to be that keen. In add-on, the rut from this displaced air is going to live diluted as it spreads through the air below the fan.
What this agency is that you lot are not going to experience the temperature increment significantly.
This does not mean that the opposite part of ceiling fans is useless, though. If you lot function the ceiling fan in winter mode in conjunction alongside an external rut source like a radiator, space heater, or woods-burning stove/fireplace, then the fan makes rut distribution much more even, increasing the effectiveness of these heat sources.
three. Ceiling Fans Are Outdated
Ceiling fans accept undoubtedly come nether force per unit area regarding relevance since the advent of free energy-efficient air-conditioning in addition to heating equipment. Despite the challenges, ceiling fans are withal plant in a significant pct of homes worldwide.
Ceiling fans are however relevant and accept a role inward the abode. Fans fitted amongst a calorie-free serve as a dual-function appliance providing light together with making the room experience comfortable. The fans remain the about efficient inwards price of circulating air around a room, and they’re cheap to function.
Modern blueprint styles are endless together with cater to every possible gustation as well as are oftentimes a feature in a room that accentuates the room’s décor without getting inward the way.
Being attached to the ceiling frees up flooring and wall space, as well as, inwards terms of price, ceiling fans are significantly cheaper than a chandelier or designer calorie-free.
4. Running the Fan 24/vii Is Expensive
A modern ceiling fan is one of the cheapest appliances to work inward a domicile, even if yous run it 24/seven (although this is non necessarily the best idea). When running on the highest speed setting, ceiling fans solely swallow betwixt 25 to 70 watts of electricity. DC ceiling fans swallow the least.
Let’second compare this to the average consumption of common household appliances
| Appliance | Average – Watts | Kilowatt | Cost to function per hr in Cents |
| air conditioning Motor Ceiling Fan | lxx | 0.07 | 0.93 |
| DC Motor Ceiling Fan | 30 | 0.03 | 0.39 |
| Kettle | ane 700 | i.vii | 22.67 |
| Hair Dryer | 2 200 | ii.two | 29.28 |
| Washing Machine | 500 | 0.v | 6.65 |
| Ventless Heat Pump Dryer | 800 | 0.8 | 10.64 |
| Vented Electric Dryer | three 000 | 3 | 39.93 |
| Ventless Condenser Dryer | three 000 | iii | 39.93 |
| Vented Gas Dryer | 1 800 | ane.viii | 23.95 |
| Refrigerator | 350 | 0.35 | four.65 |
| Electric Oven | 3500 | iii.5 | 46.58 |
| air conditioning – 9000 BTU | 900 | 0.9 | xi.97 |
As seen to a higher place, ceiling fans cost less than 1 cent per hr to function. Compare this to the dryers that swallow about twoscore times more than per hr.
five. air conditioning in addition to Ceiling Fan Should Not Run Together
Many people will say you lot that running an AC as well as ceiling fan together makes both systems less efficient too wastes money. The opposite is true.
Running your ceiling fan together with air conditioning simultaneously is an first-class thought equally they complement each other perfectly. An air conditioning blows hot or cold air from vents located either high upwards or low downward inwards a wall or fitted into the ceiling.
The closer you are to the duct, the more than pronounced the temperature issue volition live. The temperature departure will feel less if you lot’re far from the vent.
Vents just about floor degree tend to cool the lower layers of air inward the room, cooling your feet just leaving your upper torso parts warmer. This is due to cold air sinking patch hot air rises.
Running your ceiling fan patch the air conditioning is besides on assists the air flowing from the air-conditioning to live circulated evenly throughout the room, removing warm and common cold pockets of conditioned air.
At the same fourth dimension, in summer, the air circulation created past the ceiling fan, fifty-fifty when real slight, makes you feel comfortable due to the air current chill event that nosotros spoke almost earlier.
As the ceiling fan and the AC go in unison to make y'all more comfortable, the AC too the fan tin be function at higher temperatures as well as lower speeds, respectively, resulting inwards savings on your utility neb.
six. More Blades Means Greater Airflow
A pop misconception is that a ceiling fan amongst more than blades will produce more airflow. The truth is that many factors contribute to a fan’sec airflow characteristics.
- Blade configuration: As the issue of blades increases, the drag increases, then the motor has to operate harder to rotate the blades.
- Shape too size of blades: Fans with two to iv smaller blades produce a more focused column of air every bit they tend to spin faster. Long blades tend to generate a much gentler, wide-spread breeze.
- Motor type: The type of motor used inwards the fan directly affects how fast the blades plough too how efficient the fan volition be. DC fans make more torque than AC motors, thence allowing a smaller motor to be used, permitting a compact fan design piece however delivering the same CFM equally an air conditioning fan.
- Blade pitch: The steeper the blade’s pitch, the more air volition live displaced, which way the motor needs to be stronger to hold its speed due to increased air resistance. Domestic fans utilise a pitch angle of between 12-fifteen°.
More than blade issue, pitch in addition to motor size accept a greater influence on airflow.
seven. People Can Be Decapitated By Fan Blades
A ceiling fan is capable of causing severe injury together with fifty-fifty death if a heavy fan falls from a ceiling onto a individual. Still, no documented record of decapitation by a ceiling fan exists.
Ceiling fans are mounted at least vii ft (2.one k) to x ft (iii thousand) or more than from the flooring. You’re unlikely to reach the blades unless yous’re standing on something.
Furthermore, fan blades are mostly lightly constructed and made of woods composites, plastics, or thin metallic sheeting that easily bends or breaks. The fan would need a robust, abrupt blade driven past a powerful motor to decapitate individual. Neither of which are establish on ceiling fans.
Ceiling fans rotate with the blade’s leading edge higher than the trailing edge due to the pitched blueprint. Entering the blades from below volition deflect the blade off your caput before the leading edge can hit yous. In wintertime fashion, the leading border would be exposed together with can potentially cause superficial injury.
viii. Ceiling Fans Are Dangerous
Ceiling fans are non inherently unsafe when they’re correctly installed in addition to used. Injuries resulting from ceiling fans are actually rare in addition to when they make hap are mostly tiddler injuries.
Most injuries involving ceiling fans are caused past accidental contact alongside the blades. Accidental injuries are generally caused past not being aware of the fan’s location when, for example, stretching your arms upward near a low-hanging fan, standing upwards onto a chair, etc. Injuries are most commonly inflicted on the caput, arms, hands, and fingers.
Falling ceiling fans are extremely rare. Even if they do fall out of the ceiling, they are frequently caught on the wires, and then they don’t autumn to the flooring or onto people.
When fitting a fan, reckon the place as well as positioning of piece of furniture inward the room to ensure children tin’t come up into contact alongside the fan when they climb onto or jump on the article of furniture. Bunk beds in addition to loft beds in bedrooms are especially risky if the room is fitted with a ceiling fan due to the bed’second tiptop.
Fitting the correct fan for the specific place will go a long way toward preventing injury. A even out mountain fan on lower ceilings is a expert way of ensuring the fan is high plenty from the floor.
Fan maintenance is an essential factor that is frequently overlooked. Fans take regular cleaning together with dusting to ensure that the fan motor breather vents don’t become congested and forestall the fan motor from running hot. Although unlikely to pass off, If a spark occurs inward an overheated motor, the flammable dust make-upwards tin can ignite, setting burn to the home.
9. Outdoor Ceiling Fans Are Pointless
There is a myth that ceiling fans installed in outside areas are every bit pointless because the space is besides large to benefit from the cooling action.
As I order, this is only a myth. Ceiling fans are swell for outdoor areas such as patios, entertainment areas, or your favorite outdoor infinite. The cooling machinery acts on people, and then if people are around the fan, they volition benefit. Outdoor ceiling fans are peculiarly effective inward humid regions.
Outdoor fans are built to withstand harsher climatic conditions as well as are made to tolerate moisture and resist corrosion. Models fitted amongst lights serve a dual purpose by providing calorie-free together with making y'all comfortable.
Your option of designs, shapes together with size options for outdoor fans is vast, making the fan more than just a fan. The fan is both practical too a feature that volition heighten the ambiance of outdoor spaces.
ten. All Ceiling Fans Must Use a Fan-Rated Junction Box
It is slowly to say that all ceiling fans must be fitted using a fan-rated junction box. I accept made like statements myself. When we get to the specifics, yet, this is really non necessarily true.
A junction box serves a dual role by housing the electric connections betwixt the fan in addition to the electric provide cables as well as as well serves every bit a mounting bespeak for the fan mounting bracket when rated for the purpose.
The National Electrical Code (NEC Section 314.27 ( C )) stipulates that solely fans weighing 35 lbs in addition to more involve to be fitted to a junction box that is specifically rated in addition to labeled for function amongst ceiling fans by the manufacturer.
Fans weighing less than 35lbs make non necessitate a fan-rated junction box and can be attached to the ceiling using regular junction boxes.
Old plastic junction boxes property lite fixtures such as plastic calorie-free fittings are more often than not not rated every bit fan junction boxes unless expressly stated on the box. To live prophylactic, replace the one-time junction box with a metal fan-rated box.
eleven. Ceiling Fans Must Be Directly Secured to a Joist
Ceiling fans should be secured to joists. This is what supports their weight. However, you lot don’t take to screw the fan directly into a joist, which would bound your placement of the appliance.
An off-eye ceiling fan inwards a room doesn’t wait adept. Ceiling fans are typically located inwards the center of a room. So, what happens if this placement falls between two joists? Well, you lot just brand purpose of the especially designed ceiling fan span.
The duet is a metallic pole attached between two joists. An adjustable saddle loops around the rod, providing a secure anchoring indicate for the fan’second junction box. The fan and so attaches safely to the junction box.
Braces are available inward several different configurations depending on whether you take ceiling access. The braces are length-adjustable in addition to are attached to the joist amongst screws or through an innovative threaded design that wedges the twosome between the joists.
