Dehumidifier Energy Cost

Cost of living is something that keeps going up dramatically. The economy is tough and more and more people are looking for ways to save money. One of the most common questions when it comes to purchasing a dehumidifier is how much does it cost to run a dehumidifier?

Dehumidifier energy cost will vary quite a bit from unit to unit. Some dehumidifiers will run up your electricity bill a substantial amount, while others, such as Energy Star rated units, will be quite cost effective. The first thing to look into will be whether the unit is made with a refrigerator coil system or a desiccant system.

Refrigerator coil systems are the most effective. The dehumidifier energy usage varies from unit to unit but more models now are highly energy efficient.

A desiccant system is the least cost effective dehumidifier. The unit has to use hot air to extract the water from the desiccant material. This means this style of dehumidifier has to consume a lot more energy to do the same job. On average, a desiccant dehumidifier will be 50% less energy efficient then a refrigerator coil system.

The next step is to look for a model that’s Energy Star rated. Energy Star is a government group that evaluates a host of electrical products to determine how energy efficient products are. To receive an Energy Star rating the unit must be at a minimum 15% more effective than its non-rated counterpart. Buying an Energy Star dehumidifier will make a significant difference in total operating costs.

Once you have found a unit you can see how much electricity it uses and calculate how much the unit will cost to run during a certain period of time. Here is an example of how to calculate the cost for running the unit for a year’s time:

First, you need to find out the wattage of the unit. Then you take the wattage and multiply it by the hours in use and divide by 1000. This will give you your kWh measure.

For example,

(400 watts x 10(hours per day) x 365(days per year)) divided by 1000

=1460kWh x 7cents(kWh)

=$102.2/per year

This method will only give you a rough estimate of how much a dehumidifier energy cost will be. There are many other factors that come into play other than strictly the dehumidifier energy usage per hour.

For example, a very efficient unit compared to one that barely removes humidity. Unit A use 25% more energy than Unit B, however, Unit A successfully controls moisture with a run time of 4 hours per day while unit B controls the same moisture running 10 hours per day. Clearly, unit A is far superior and energy efficient even though the unit technically uses more power while running.

Do dehumidifiers use a lot of energy? If using a desiccant one the answer is yes; however, many units, such as the Energy Star ones, cost quite little to operate.

The dehumidifier energy cost will vary depending how much humidity you have and how big an area is. For a typical basement, you can expect to pay around $15-25 per month.
