During the period when you come across frequent excess indoor moisture levels, your home becomes an ideal breeding ground for mites, dust, and fungi. For this reason, allowing free air to flow into your home can help to reduce this excess moisture. However, some buildings do not receive enough air to remove the excess damp. When issue like this arises, you should plan on getting a dehumidifier.

For small places like bathroom stalls and storage spaces, cordless dehumidifiers like the Eva-Dry E-333 are usually the best option. While for large areas, powered driven dehumidifiers serve as better options to help remove excess moisture.

Electric dehumidifiers (as the name implies) operate with power source. Using this models draws more thought to the amount of energy consumed. This fact brings the question: how much electricity do dehumidifiers use?

But first, let’s look into the basic factors behind electric models.

 


 

How Does an Electric Dehumidifier Work ?

First, you need to know how a dehumidifier works.  The idea is quite basic and easy for you to have great insight.

A temperature of the surface of a metal is lowered. Humid air that touches this surface also gets cooled. Water starts to condensate on the metal because cold air has more liquid content than warm air. The moisture gathers in a plastic bucket which can be emptied regularly.

Most models work using this principle. However, these machines have different levels of it works.

 

 

How Much Electricity Do DeHumidifiers Use ?

As with most household types, the essential thing to take into account is how much energy it consumes. You should also look into how well your unit uses this energy. The energy consumption of your device (in kilowatts per hour) can be found on the label and the manual of your product.

Secondly, have a look at the energy efficiency, also expressed as the energy factor. Dehumidifiers that use electricity have energy factors based on how it removes Water per kWh. The Energy Star website provides the energy factors of standard models for easy way to compare the units.


 

Large capacity models perform better than smaller models. On the other hand, the product with the highest energy factor may not be the ideal or low-cost option. This happens because most rooms do not require the models with high capacities.

Another factor to take in to account is the apparent price range between brands and models. Dehumidifiers that use batteries work well in spaces that are limited.

The Approximate Operating Cost of Electric Dehumidifiers

An average model of dehumidifier works at 280 Watts- hour.  Let us assume your present power rate is 15 cents/kW, the Unit uses 4.2 cents of power every 60 minutes. Hence, if you put it on for 12 hours daily, the cost will become 12 * 4.2 cents = 50.4 cents. Surely, these calculations shown above are based on estimated numbers; they show a good idea of the operating costs.

 


 

Factors to Consider Before Getting Electrical Dehumidifier

In most cases, factors such as the humidity levels and the size of the room define the operating cost of a dehumidifier. Other factors include the period you need to keep it running and the kWh rate charged by your local power company. The temperature of the space where you operate also stands as another factor to focus on.

Besides, not all spaces have a steady source of power. Ensure to take into account the noise levels of your unit as some models make more noise than others. You should read the reviews carefully before making the purchase.

With all these figures and factors you have seen in this article, you wonder if you can reduce the energy usage of your dehumidifier. The truth is that it does. Let’s show you how.

How to Reduce Your Dehumidifier Costs

Although these devices protect our homes from the harmful effects of damp, using some models can result in massive electric bills. Below are some few ways to reduce costs and still make your home free from excess moisture.

 

Ensure You Purchase an Energy-Efficient Dehumidifier

Before embark on shopping for one, try to look for Energy Star website. The website shows that such models use 10% to 20% less humidity to remove an equal amount of moisture as regular models.  Buying such saves you a good sum of money in the long run and the prices of both models aren’t of great difference.

Free flow of Air through Other Means

Ensure that air flow into the room freely to help reduce excess moisture. Living spaces and basements most time get damp because the water vapor dispersed in the air has no means to escape.

Installing fans and small windows create enough airflow and easy way to let out air. These ways help to circulate the air and solve the excess moisture problem.

 

Use Calcium Chloride When Your Unit is off

Calcium Chloride is a chemical compound that can reduce the moisture content in the air. For this reason, this substance acts as an essential ingredient of products used to remove ice from surfaces. Most home improvement and hardware stores now stock calcium chloride products as an option for dehumidifier.

While the machine is off, you can place bowls with calcium chloride crystals in damp rooms around your house. When this substance absorbs water, it turns to brine. You may flush the salty water down the toilet.

 

Do Not Dehumidify Always

Most Electric models do not perform well in a colder indoor space. With this in mind, they work better in rooms with high temperatures.

In some areas, it’s ideal to use the unit during the humid season when the basement is kept warm in the cold season. The basement will be kept dry as the warm air rises to the upper levels of the building.

 


 

Conclusion

Electric Units help to remove excess moisture which can cause adverse effect to your home comfort. They make use of electricity measured at kwH and various models have different levels of how they work. Other factors also need to be taking into account before shopping for an electric dehumidifier to reduce the power it consumes. However, there are some ways to reduce your running costs thereby saving you money in electric bills.
