How Much Does A Dehumidifier Reduce Your Utility Bill?

  • If you run your dehumidifier for 8 hours each day for 30 days, your electricity bill will rise by $15.36, or 13%.

Will using a dehumidifier help me save money on my electricity bill?

Heat is the summer’s worst enemy when it comes to comfort. Humidity, on the other hand, is a close second. High temperatures can be made tolerable on a dry day. When the moisture content in the air rises, though, it prevents your body from sweating adequately, making you feel hotter than the actual temperature.

The installation of a whole-house dehumidifier is one technique to combat humidity during the summer months. Dehumidifiers do more than make a home feel more comfortable; they also save money in a variety of ways.

Installing a whole-house dehumidifier necessitates the assistance of an indoor air quality specialist who can assess your needs and appropriately integrate the dehumidifier into your HVAC system.

Air Mechanical, Inc.’s skilled indoor air quality team will help you choose and install a whole-house dehumidifier in Ham Lake, MN.

How a dehumidifier saves you money

When you turn on a dehumidifier, it will immediately begin to lower your utility bills. You won’t need to run the air conditioner as much because your home will seem cooler with less moisture in the air. Reduced stress on your air conditioner implies fewer service needs and a system with a significantly longer lifespan, in addition to lower electricity expenses. What better way to save money in the long run than to extend the life of your air conditioner before it needs to be replaced?

Don’t be concerned about the additional electricity required to run the dehumidifier. Dehumidifiers consume a fraction of the energy that an air conditioner does. (A central air conditioner runs on 220 volts, while a dehumidifier runs on 100 volts.) If you can reduce your air conditioning use by just one hour per day due to the dehumidifier’s activity, you’ll save roughly $20 per day… and you’ll probably be able to lower it even more.

By absorbing moisture onto the evaporator coils, air conditioning systems help to reduce humidity. Air conditioners, on the other hand, are not designed to control humidity and have minimal effect at humidity levels above 50%. If your home suffers from excessive humidity, investing in a whole-house dehumidifier to supplement your air conditioner is a good choice.

The other advantages of a dehumidifier, such as decreased moisture damage to furniture, reduced mold and mildew growth, and improved health, will save you money in indirect but substantial ways.

If humidity is making your summer miserable, or if you’ve discovered moisture damage in your home, a whole-house dehumidifier should be installed in Ham Lake, MN. Call Air Mechanical, Inc. immediately for advice and installation services that will ensure you get the best dehumidifier for your needs.

Is it true that a dehumidifier uses a lot of electricity?

The energy consumption of a dehumidifier is quite minimal. A tiny 30-pint dehumidifier consumes 300W of power. A typical large 70-pint dehumidifier consumes 700W of power. A dehumidifier uses significantly less electricity than a water heater, air conditioner, or even a hair dryer.

In a year, how much electricity does a dehumidifier consume?

Germs and molds thrive in environments where the humidity is too high for lengthy periods of time. This is why it’s crucial to have a well-ventilated home. However, not every home can be adequately aired to remove all extra moisture. If enough ventilation is not possible, a dehumidifier should be purchased.

How electric dehumidifiers work

Let’s start with a simple explanation of how electric dehumidifiers work. The concept is actually quite simple: The temperature of a metal surface is reduced. Humid air that comes into contact with the metal surface cools down as well. Water condenses on the metal because cold air can contain less moisture than warm air. This condensation is collected in a plastic bucket that may be emptied on a regular basis. Despite the fact that most electric dehumidifiers operate in this manner, there are significant disparities in efficiency.

Dehumidifier energy consumption

The most significant factor to consider is the device’s energy usage, measured in kilowatt-hours (kWh), as well as how efficiently it consumes that energy. The energy usage is always listed on the product’s label. Next, look at the energy efficiency, which is measured by the energy factor. The energy factor for an electric dehumidifier is dependent on its performance per kWh, so this will tell you how many liters of water are removed from the air per kWh. By visiting the Energy Star website, you can simply compare energy factors of typical models.

Larger gadgets are frequently more efficient than smaller devices. However, because most places do not require high capacity devices, the device with the highest energy factor may not necessarily be the best or cheapest option for you. There are also significant price discrepancies between models and manufacturers when it comes to purchasing. Non-electric dehumidifiers are worth considering, especially if you have a moisture problem in a small space.

What would be the approximate operating cost of an electric dehumidifier?

Let’s look at a standard model that uses 280 Watts each hour. An electric dehumidifier requires 4.2 cents of power per hour assuming the current power rate is 15 cents/kW. As a result, if you use it for 10 hours each day, the cost is 10 hours * 4.2 cents = 42 cents per day, or $153.30 per year. Of course, the preceding calculations are based on estimates, but they provide a reasonable picture of the operational costs.

So what things should you take into consideration when buying an electric dehumidifier?

The cost of running an electric dehumidifier in real time is determined by the size of the room, the humidity in the area, the number of hours you require it to run, and the kWh rate charged by the power company. The performance of an electric dehumidifier is also influenced by the ambient temperature. Furthermore, not every space will have a reliable power source. Always consider the noise that an electric dehumidifier produces. Some electric dehumidifiers are as loud as pedestal fans, so give them a test run before you buy.

When choosing a dehumidifier, be sure to do your research because the operating costs of a dehumidifier that is too large may be higher than the cost of adding adequate ventilation. In many cases, a high-capacity electric dehumidifier is simply overkill. We hope this information aids you in making an informed decision.

Is it cheaper to run an air conditioner or a dehumidifier?

However, this convenience comes at a cost, and many people ask if it is more cost effective to use an air conditioner or a dehumidifier. When both units are of average capacity and have typical running times, it is generally cheaper to run a dehumidifier than an air conditioner. Regardless, because each has its unique role, this does not mean you should get rid of your air conditioner and replace it with a dehumidifier.

Both air conditioners and dehumidifiers have their functions, and understanding them will keep you from preferring one over the other without reason.

On average, you can anticipate to pay the following amount on your monthly power bill:

  • Depending on their size, portable dehumidifiers can cost anywhere from $25 to $350 per year. Although this isn’t the most accurate way of looking at it, it breaks down to $2 to $29 every month. In the hot and humid winter months, most dehumidifiers, like air conditioners, operate nonstop, whereas in the summer, they barely run or are even turned off.
  • Your monthly electricity bill will normally increase by $80 to $125 if you have central air conditioning.
  • Electricity costs for mini-split air conditioners with an average capacity (about 12,000 to 20,000 BTU) range from $35 to $50 per month. Portable or window air conditioners with equivalent BTU capabilities should cost around half as much.

Let’s look at the similarities and differences between your air conditioner and dehumidifier now that you know the pricing.
