How Much Electricity Does An Exhaust Fan Use – Exhaust fans provide essential ventilation in homes such as bathrooms to prevent excess moisture. Exhaust fans can reduce the risk of mold growth, making your home a comfortable and healthy environment. If your home does not have an exhaust fan, consider installing one as soon as possible to avoid costly damage.
An exhaust fan will be useful in any room where there is humidity. Bathrooms, kitchens and laundry rooms naturally develop moisture through use. Eliminating excess moisture prevents the growth of mold and mildew and protects fixtures, furniture, paint and finish.

There are also exhaust fans throughout the house. These systems are configured in a variety of ways, but all improve indoor air quality. They can be used in conjunction with HVAC systems as well as installed kitchen, bathroom and other fans.
Best Humidity Sensing Bathroom Exhaust Fans In 2022
Choose exhaust fans based on airflow and noise level. Airflow for all fans is measured in cubic feet per minute (CFM). The required air flow depends on the size of the room and the use of the fan. Airflow needs vary from room to room.
Choose a sound level that is tolerable in a quiet home. Expect quieter fans to be more expensive, although quieter isn’t always better. Some people prefer louder fans in their bathrooms because they can reduce the noise from the sink and toilet.
The lamps are equipped with many additional features such as light switches, heaters and automatic timers that determine the humidity level. Avoid fans that turn on and off with a light switch, as they often turn off before the fan can turn on.
The type of fan chosen will also depend on the existing duct systems. Bathroom fans come in three main types:

Whichever fan you choose, make sure it blows outside and not in the attic, as mold can develop.
Proper exhaust fan installation is critical to your family’s health and the preservation of your property. Electrical installation and proper ventilation require the skills of a professional electrician. Many people do not know that exhaust fans must be vented to the outside to work properly, and they are not properly ventilated in the attic or near the attic, causing costly losses.
Improperly installed and unvented exhaust fans simply divert excess moisture from the air to another area of your home, causing wood rot, mold growth, and more.
It’s always better to be safe when it comes to family and home. In Wichita and the surrounding area, call Graf Electric at 316-686-2090. The energy consumption of bathroom fans is measured in watts. The wattage of a device is a measure of the total electrical flow. A more powerful bathroom fan means it uses more electricity and will cost more.

In general, the power of a bathroom fan can vary from 10 watts to 100 watts. However, if the bathroom fan has a heater, the total power can be more than 1400 watts.
Home owners should remember that bathroom lights should not be used continuously 24 hours a day. It is important to turn off the exhaust fans when they are not in use, but they should be left on for at least 20 minutes after the shower to remove all the moisture.
Bathroom bathroom fans can be controlled by countdown timers, humidity sensors and even motion sensors, so they turn on and off automatically – saving energy.
If you want to know the annual costs, if your bathroom fan runs continuously throughout the year, just do a simple calculation.
Should My Home Have An Exhaust Fan?
The first step is to determine the maximum speed or CFM of your bathroom fan. You can also add maximum power if it has a heater or other extra features.
Once you’ve determined your maximum power, divide that number by 1000 to convert watts to kilowatts (kW).
When you have the number of kilowatts, multiply by the cost per kilowatt hour in your area. The national average cost of electricity per kilowatt hour is about ten cents or $0.10 per kWh.
And a full year is 8,760 hours, so multiplying 8,760 hours by 0.005 kWh gives an annual cost of $43.80.

Again, keep in mind that this is about 24/7 continuous use of the bathroom fan, which is almost never the case. To get a more realistic number, you can calculate how many hours per day your bathroom fan will run and multiply by 365 days.

Energy Star is a program run by the US Environmental Protection Agency that certifies household appliances as energy efficient. In order for a bathroom fan to receive an Energy Star rating, it must meet certain minimum requirements.
A key factor in the Energy Star rating is that a bathroom fan must have a basic “efficiency” rating, which is the number of CFM per watt. U

It is essentially an indicator of energy consumption or performance. You can read my full guide to choosing the right CFM for your bathroom fan here.
To get this rating, simply take the CFM of the bathroom fan and divide it by the maximum wattage. The higher the coefficient of efficiency, the more efficient the bathroom fan.
Bathroom fans 10-89 CFM should have an efficiency coefficient of 1.4 (1.4 cfm per watt).
For bathroom fans in the 90-500 CFM range, the bathroom fan must have an efficiency rating of at least 2.8 (2.8 cfm per watt).

If your bathroom fan has multiple CFM settings or additional functions such as a radiator, you want to get the maximum power. When you have your maximum watts, you need to divide by 1000 to convert to kilowatts. When you have the number of kilowatts, you can multiply it by the local cost of kilowatt-hours.
After doing this multiplication, you can multiply the price per kWh by the number of hours in the whole year, which is 8760, to get the final estimate of the annual cost.
