Cost To Operate A Ceiling Fan 24/7 (Tabular Array Alongside Monthly As Well As Annual Costs)

As you take near probable already heard, ceiling fans are 1 of the cheapest ways to keep you lot cool and inwards comfort during the sweltering summertime months. But equally it and then happens, not all of them are created equal.

Below, y'all tin notice a table of the average running toll of differently powered ceiling fans. On elevation of that, nosotros will give you lot an overview of factors that can impact the terminal cost of running your ceiling fan and tips on what to make to trim the price.

On average, running a low-powered ceiling fan all day costs 0.016-0.xi USD (0.17-0.12 GBP or 0.036-0.25 AUD). Running a medium-powered ceiling fan all twenty-four hours costs 0.115-0.24 USD (0.124-0.259 GBP or 0.26-0.54 AUD). Running a high-powered ceiling fan all 24-hour interval costs 0.242-0.383 USD (0.262-0.41 GBP or 0.55-0.86 AUD).

Power Ratings of Ceiling Fans

First, permit’sec look at approximately power ratings that tin let out a lot nearly your ceiling fan.

The voltage is the pressure level that pushes electricity (measured inwards V). The typical voltage for home ceiling fans is 120 V.

Next, nosotros take wattage too amperage.

Wattage is the measurement of energy that is used to run the fan. Therefore, the higher the ceiling fan’s wattage is, the more than power it uses too the greater your electric pecker volition be. Ceiling fans commonly come alongside multiple power settings. On the lowest setting, the fan uses fewer watts than on the highest setting.

The amperage is the force of the electrical current. It allows yous to calculate the wattage. At 12O volts, ane amp is equivalent to 120 watts drawn past a ceiling fan.

Average ratings for a depression-powered ceiling fan are 0.25 A in addition to almost thirty due west. For a medium-powered fan, it is 0.iv A together alongside 48 W, together with a high-powered fan starts around 0.6 A or 75 westward.

The component to check when buying a ceiling fan is its airflow efficiency (stated in CFM/west). It is determined by dividing the fan’second CFM (cubic feet per minute), which is the total of air a fan tin move inward lx seconds, by its wattage.

For optimum efficiency, look for a fan that has high CFM too operates at depression wattage. According to ENERGY STAR requirements, at least 75 CFM/westward at the highest speed is needed in social club for the fan to live considered efficient.

Calculating Wattage

If yous don’t know the wattage of a fan:

Watts = Amps 10 Voltage

With ceiling fans (those amongst air-conditioning motors especially), you likewise take to reckon the ability ingredient. It is the ratio between the power that is drawn (apparent power) too the power that is actually used (working power).

An ideal device would accept a ability ingredient of 1.0 (meaning 100% of the power is used together with none is wasted), 0.ix is slightly worse, significant that ninety% of free energy is used (the working power), as well as 10% is wasted, and then on.

The equation volition and then alter to:

Watts = Power constituent 10 Voltage x Amps

If y'all desire to know entirely the power ingredient:

Power element = due west / (volts 10 amps)

To calculate the running toll, commencement multiply the fan’second westward by the price of the electricity (that is stated inwards kilowatt an hr (kWh)). Then split the issue by thou to convert the issue to kWh, which is the hourly cost of running the fan.

The hourly toll of running a fan = (the toll per kWh x watts) / K

For example: The fan is 120 W, in addition to the price is x cents kWh, so $ 0.1

(0.one x 120) / grand = $0.012

Cost of Electricity

The price of electricity varies amongst state, region, in addition to exact locality.

The average cost of electricity for a residential customer inwards the the States is 13.31 cents (0.133 USD). The highest average cost of 32.76 cents per kWh can live institute inwards Hawaii, in addition to the lowest average rate is inwards Louisiana at 9.37 cents per kWh.

In the United Kingdom of Great Britain and Northern Ireland’second average electricity price is xiv.4 pence per kWh or 0.144 GBP. The lowest cost of 13.86 p can live enjoyed by people in East Midlands, piece, inward contrast, North Scotland comes alongside xv.6 p / kWh.

Finally, Commonwealth of Australia comes amongst a toll average of close to 0.xxx AUD. While the lowest rates are recorded in Tasmania in addition to New South Wales (starting around 25 cents), the highest ones (even equally high every bit 35 cents kWh) are recorded inwards South Commonwealth of Australia.

If you lot would like to compare this to the toll of running other types of fans, I take an article on the electricity utilisation of 11 different types of fans that yous may notice helpful.

What Could Affect the Cost?

It is good to call up that ceiling fans are non designed to cool the room. They serve to cool the people and keep them comfortable.

Even though they are an affordable cooling choice, it is reasonable to plough them off when leaving the room, especially when trying to trim the electricity pecker.

That being said, in that location are multiple variables that bear upon the concluding substance that the running of a ceiling fan will toll yous.

Lighting System

The beginning affair where y'all can salve money is buying a fan without lights. If you require lights, it is more price-efficient to opt for LED instead of incandescent light bulbs (y'all are likewise less probable to contend amongst having lights that are as well dim).

Comparisons show that incandescent lights tin can function upwards to vi times more watts during their performance, and their lifespan tends to be as much equally twenty times shorter than the one of LED lights.

Therefore, they could annually relieve the planet around 265 kW of power together with add together more than $30 to your bag. And that is without taking into account their long lifespan.

Fan’s Blades

The number of blades too makes a difference in the fan’sec efficiency. Typically the fewer blades the fan has, the faster in addition to more efficiently it tin run, merely it tends to be noisier as well. When in that location are likewise many blades, they tin create a drag and ho-hum down the fan.

For residential function, the fans amongst four or five blades are considered to bang the perfect residue between the airflow efficiency as well as the noise level.

However, nowadays, the number of blades is non the only defining ingredient. The length in addition to form of the blades will too influence the fan’sec functioning. To be more than exact, the angle of the blade, the so-called blade pitch, affects the fan’second air efficiency. Ideally, the angle should live around 12-fifteen degrees.

Therefore, the low drag blueprint as well as appropriate blade pitch are more important aspects than the issue of blades themselves.

Maintenance

Keep in mind that proper maintenance plays an essential part inward a fan’second cost-efficiency.

When the fan is covered amongst dust, the dirt can get into the motor too effort it to work less smoothly. On pinnacle of that, the dust or grease construct-upwardly on the blades often interferes amongst their spinning motility. In the video below, yous can find out how to properly make clean your ceiling fan.

Age of the Fan

An older fan volition naturally non be operating optimally, too ane of the results of clothing as well as tear too aged motors is an increase inward the ability used to operate the fan.

Overloaded Circuits

Ceiling fans don’t require a dedicated circuit. However, if your fan is connected to an overloaded circuit, so it tin can describe inconsistent ability during performance. Not entirely could you lot observe this in a stuttering rotation of the blades, just it tin can harm the fan’sec mechanics, causing it to describe more than power than it should.

The safest bet to observe a price-efficient ceiling fan is to buy an ENERGY STAR-certified fan. The fans that qualify for this certification are highly-efficient, toll-friendly, in addition to typically come with an extended warranty.
