The power consumed by bathroom fans is determined by the wattage, which typically ranges from 10-50 watts. Simple fans use about the same amount of electricity as a single light bulb, but fan units that include lights and heaters use significantly more energy.
Would you like to know how much energy does a bathroom fan uses each year?
As energy prices rise and we all try to conserve energy to keep our planet clean, it’s important to analyze every appliance in our homes that consumes energy. We don’t always realize that the smallest things can make a big difference! You invest in your comfort and health when you spend money on such electrical appliances.
Here’s A List Of The Best Bathroom Fans This Year:
What is the electricity consumption of different types of bathroom fans?
The fact that different types of fans use different amounts of energy makes perfect sense. Even though the type of fan has little impact on consumption, wattage is more important, wattage tends to be closely tied to the type of fan.
Bathroom Vent Fans
Vent fans have an airflow rate measured in cubic feet per minute (cfm). The standard vent fan moves air at a rate of around 5 cfm with about 1 watt of energy.
A 1000 cubic-foot bathroom (10ft x 10ft x 10ft) requires a fan that can move 1000 cubic feet per minute of air. A fan using this power will consume about 200 watts, or 1000/5, to remove moisture from a bathroom.
Small bathrooms that measure 125 cubic feet (5ft by 5ft by 5ft) require a fan with a 125 cfm. It will require 25 watts to power a small bath vent fan.
Bathroom Ceiling Fans
Depending on the voltage supplied to the fan, a typical bathroom ceiling fan will consume between 40 watts and 100 watts. Using a 10 cent kilowatt price, it is estimated that the cost of operating a ceiling fan will be 0.4 cents per hour at lower speeds and 1 cent per hour at higher speeds.
Moreover, larger fans consume more power. Electricity costs increase with larger fans because more power is required to spin the blades.
How To Calculate The Cost Of Running Bathroom Fans?
It is possible to figure out how much electricity an appliance uses by using certain methods. However, these are only rough estimates. By using these figures, you can determine when and how many fans to use.
A simple calculation can tell you how much money your bathroom fan will cost you if it is run continuously throughout the year.
Determine how many watts does a bathroom fan use at maximum speed or CFM in the first step. Adding the maximum wattage is also possible if it has a heater or other extra features.
To convert watts into kilowatts (kW), you will need to divide the maximum wattage by 1000
1. Divide the Bathroom Fan Wattage by 1000 = kilo-watts (kW)
For a 50-watt bathroom fan, the kWh will be 0.050 kWh. In order to figure out your cost per kilowatt-hour in your local area, you will need to multiply the number of kilowatts by your local electricity price per kilowatt-hour.
In the US, the average cost of electricity is about ten cents per kilowatt-hour or $0.10 per kWh (10/100=$0.10).
While in Australia, electricity costs approximately 34 cents or $0.34 per kilowatt-hour(34/100=$0.34).
2. Multiply Bathroom Fan Kilo-Watts (kW) with electricity price of your local area (in dollars) = Bathroom Fan kWh Cost
For the US,
Bathroom Fan kWh Cost = 0.050-kWh x $0.10-kWh
Similarly, for Australia
Bathroom Fan kWh Cost = 0.050-kWh x $0.34-kWh
3. Multiply Bathroom Fan kWh Cost by 8760 Hours = Annual Cost
It is important to note that this is for continuous use of a bathroom fan 24/7, which is very uncommon.
For the US,
For an entire year, there are 8760 hours,
Annual Cost in the US = 8760 hours x $0.005 kWh
Similarly, for Australia
Annual Cost in Australia = 8760 hours x $0.017 kWh
1. Do bathroom fans lose heat when running?
Yes, bathroom fans lose heat when they run. You can reduce heat loss by running fans at the lowest possible speed. This will keep more warm air inside your home. Though this might not always be possible, you can experiment with various speeds to make your exhaust fans more efficient and cost-effective.
2. Is it a good idea to run the bathroom fan while showering?
The humidity in the bathroom is increased by showers. When the temperature rises high enough, condensation appears on the mirror and other surfaces in the bathroom. It can lead to mold growth (fungus) on the surfaces. So, you should keep a bathroom fan running for at least 20 minutes after you get out of the shower.
3. Is it possible for a bathroom fan to cause a fire?
When taking a shower or using the toilet, homeowners often turn on the bathroom exhaust fan. The fans are sometimes left unattended for an extended period of time to eliminate humidity and fumes. A poorly cleaned bathroom fan can ignite combustible dust and structural framing materials, resulting in a major fire event.
Electricity is one important aspect of our modern life. One of the most common electrical appliances in your bathroom is the bathroom vent fans. It will help you keep your bathroom very well ventilated. However, some people question the amount of electricity used when the bathroom fan turns on.
The electricity cost of running a bathroom fan is $43.8 (annually) and $3.65 (monthly) in the US. While the electricity cost of running a bathroom fan in Australia is $148.92 (annually) and $12.41 (monthly).
Bathroom fans are a wonderful way to keep the air in your bathroom fresh and clean. These fans help purify the air in your bathroom resulting in a healthier environment.
