Dehumidifier Energy Calculator (Cost and kWh Usage)

Dehumidifiers are an important appliance in many households, particularly in areas that experience high humidity levels. However, with increasing energy prices, it’s important to understand the energy consumption and cost associated with using a dehumidifier in your home.


How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

Your Energy Rate in kWh

The calculator includes an average energy rate (price in $/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

Before we dive into the specifics of energy consumption and cost, let’s take a moment to calculate the energy usage and cost of a dehumidifier. Assuming a power consumption of 240 watts and an energy price of $0.12/kWh, the hourly cost of running a dehumidifier is $0.03. This seems like a small amount, but it adds up over time.

Energy Consumption

A dehumidifier works by removing excess moisture from the air. Depending on the size of the unit, a dehumidifier can consume anywhere from 100 watts to 900 watts of power. This power consumption is required to run the compressor, the fan, and other electronic components of the appliance.

To put it into perspective, a 100-watt dehumidifier running continuously for 24 hours will consume 2.4 kWh of energy. That’s equivalent to leaving a 100-watt light bulb on for 24 hours. A larger model that uses 900 watts would consume 21.6 kWh of energy over the same period.

Importance and Relevance

The importance of a dehumidifier lies in its ability to reduce humidity levels in your home. High humidity can cause a number of problems, such as mold growth, musty odors, and damage to your furniture and clothing. With a dehumidifier, you can prevent these issues and maintain a comfortable living environment.

However, the energy consumption and cost associated with using a dehumidifier can be a concern for some homeowners. As energy prices continue to rise, it’s important to find ways to reduce energy usage and save money on your utility bills.

Cost in Dollars of Energy Usage

To calculate the cost of running a dehumidifier, you need to know how many hours per day you plan to use it. Let’s assume you run your dehumidifier for 8 hours per day.

The formula to calculate the daily cost is:

(hourly energy consumption) x (hours of use per day) x (energy price) = daily cost

Using our default values, the daily cost of running a dehumidifier for 8 hours is:

(240 watts / 1000) x 8 x $0.12 = $0.23

The monthly cost would be:

(daily cost) x (number of days in a month) = monthly cost

Assuming 30 days in a month, the monthly cost of running a dehumidifier for 8 hours per day is:

$0.23 x 30 = $6.91

And the yearly cost would be:

(monthly cost) x (number of months in a year) = yearly cost

Assuming 12 months in a year, the yearly cost of running a dehumidifier for 8 hours per day is:

$6.91 x 12 = $82.92

Money Saving Tips

Now that we know the costs associated with using a dehumidifier, let’s look at some money saving tips:

  • Use a timer: Set your dehumidifier to turn off after a certain amount of time. This will help you avoid running it for longer than necessary.

  • Choose a model with energy-saving features: Look for dehumidifiers with features like automatic shut-off and adjustable humidity settings. These can help you reduce energy usage and save money.

  • Clean the filter regularly: A dirty filter can reduce the efficiency of your dehumidifier, causing it to use more energy. Clean or replace the filter regularly to keep your appliance running smoothly.

By following these tips, you can reduce the energy consumption and cost associated with using a dehumidifier in your home.
