Understanding the Dehumidifier
Before we launch into answering the question about whether dehumidifiers are energy efficient, let us understand what a dehumidifier is. According to Wikipedia, a dehumidifier is an electrical device that removes excess moisture from the air in the room. It works by sucking in moisture-laden air and expelling dry air back into the room. The unit requires electrical energy to work, and this energy consumption is where the question about energy efficiency comes in.
The Energy Consumption of Dehumidifiers
Dehumidifiers vary in sizes and energy consumption, but the standard electric dehumidifier uses approximately 300 to 800 watts per hour, according to the Energy Star program. The program estimates that an average dehumidifier running for 10 hours a day will use approximately 2.84 kilowatt-hours of electricity daily. The annual cost of running the unit will depend on the electricity rates in the area where the user lives.
Tips for Making Your Dehumidifier More Energy Efficient
While the use of a dehumidifier will raise your electricity bill, you can take steps to reduce the energy consumption of the unit. For instance, placing the dehumidifier in a location where it can work efficiently is crucial. Do not block the airflow or place the unit in a location with high humidity levels. Additionally, use a timer to run the dehumidifier during specific hours of the day when humidity levels are high. Clean the dehumidifier air filter regularly as a clogged filter will affect the airflow and increase the unit’s energy consumption.
When to Consider Replacing Your Dehumidifier
If you own an old dehumidifier unit, it may not be energy efficient. The more modern dehumidifiers use advanced technology, such as adjustable humidity sensors and dual-speed fans, to work efficiently and use less energy. The efficiency of a dehumidifier is determined by a measurement known as the energy factor (EF). If an older unit has an EF of below 1.0, it is time to consider replacing it with a more energy-efficient model with an EF of 2.0 or higher.
So, are dehumidifiers energy efficient? The answer is, it depends on the unit’s age, size, and technology used. However, it is possible to make your dehumidifier more energy-efficient by following the tips mentioned above, such as placing it in the right location, using a timer, regularly cleaning the filter, and replacing it with a more modern, energy-efficient model. With proper maintenance and usage, your dehumidifier will help save you money in the long run and benefit the environment by reducing your energy consumption.
