If you’re thinking about buying a ceiling fan, it’s a good idea to know how much energy it will consume. There are a few factors to consider, including its Wattage, the size of its blades, and its efficiency. If you have a fan that isn’t energy efficient, you may end up paying more for electricity than you need to.
Cost of Running a Ceiling Fan
The cost of running a ceiling fan depends on the power tariff that you have in place in your area. This is the charge that you pay for electricity per kilowatt-hour. It is easy to calculate this by comparing how much electricity each fan consumes and the price per kWh for your region. The highest rates of electricity are found in Hawaii, while the lowest are found in Louisiana and Washington.
If you plan to run a ceiling fan non-stop for a year, expect to pay about $44 to $88 in electricity. This works out to about $0.09 per hour for each fan, depending on the size and type. These figures are based on a ceiling fan that uses 50 to 80 kilowatts of electricity. The average national electricity rate is $0.11 per kilowatt-hour. But if you aren’t going to use your ceiling fan on a daily basis, you can cut that cost down to only $5 to $10 a month.
Wattage of A Ceiling Fan
A ceiling fan is a relatively inexpensive way to cool your home. The amount of electricity used depends on its wattage. You can figure out how much the fan costs by multiplying the wattage by the average rate for residential electricity in the US. A 25-watt ceiling fan, for instance, would cost around $33 to run continuously for a year. A 75-watt fan, on the other hand, would cost $165, or a little less than two cents per minute.
The wattage of a ceiling fan is easily determined by looking for its wattage label on the bottom or back of the appliance. It will have wattage, amps, and voltage on its label. Watts are equal to voltage x amps, and they represent the capacity of the electrical appliance. This number is also helpful in determining how much electricity your ceiling fan will use.
Efficiency of A Ceiling Fan
Ceiling fans can be classified according to their efficiency by measuring the amount of electricity they use to generate airflow. Ceiling fans with higher efficiency ratings can run longer on top speed per unit of electricity. However, the primary purpose of ceiling fans is to provide thermal comfort, which means the trade-off between efficiency and thermal comfort should be carefully considered.
Currently, the DOE requires ceiling fan manufacturers to test their fans in a multi-phase power configuration. This configuration is the most representative for assessing energy use. In addition, manufacturers will be required to test their fans for the EnergyGuide label in this configuration. If they pass the test, they can earn an EnergyStar rating.
The DOE recently proposed testing ceiling fans with a seven-foot blade span using an ENERGY STAR test procedure. However, the DOE has yet to specify what voltage is required for a fan to operate on three phases. Since many large-diameter ceiling fans operate on three-phase electricity, this requirement is needed. This change will help the industry to avoid confusion when measuring the power consumption of three-phase fans.
