How Much Does It Cost To Run A Dehumidifier For 24 Hours

Having a dehumidifier in your home will help you keep it at the ideal humidity level and prevent mold from growing. A dehumidifier is an essential piece of equipment for keeping humidity levels low, but how much does it cost to run one? We’ve put together this guide with all of our best tips on how to make sure your air-conditioner or dehumidifier is running efficiently.

Running Costs of Dehumidifiers

The cost of running a dehumidifier depends on the size of the unit. The larger it is, the more electricity it will use and therefore the higher your bills will be. Most units cost between $0.05 and $0.20 per day to run depending on their size (and whether they’re brand new or used).

How Much Electricity Does A Dehumidifier Use?

Dehumidifiers are very efficient, but they do use electricity. Dehumidifiers are often rated by their kilowatt hours (KWh) of energy used per year and can range from about 1 KWh to over 100 KWh. A typical home will use anywhere from 20 to 50 kWh per day, which means that a 24-hour period could cost anywhere between $0.20 and $1.50 if you use an average amount of electricity in your home every day—it depends on how many people live there, how often they run their AC/heating system and if they have any other appliances running at the same time as well as what type of climate control system you have installed in your house!

Calculating Running Costs per Day, Week and Month

To calculate the cost of running a dehumidifier for 24 hours, you first need to know how much power it uses. The average dehumidifier takes up about 18.9 watts when running, so if you have an average-sized unit that runs at 1.5 tons per hour (1 ton = 1,000 lbs), then you can estimate that your total cost will be around $0.0075 per day ($0.64 / 24 x 365 days).

This calculation is based on an average size dehumidifier; however, smaller units may use less energy and therefore yield cheaper costs per day than larger ones do!

Dehumidifier Types vs. Running Costs

The first thing to know about dehumidifiers is that their capacity, which is measured in British Thermal Units (BTUs), dictates how much moisture they can remove from the air. The higher the BTU rating, the more moisture it can remove from air.

For example:

  • A dehumidifier with a 1,000 Btuh capacity will remove 1 pound of moisture per hour;
  • A dehumidifier with a 3,000 Btuh capacity will remove 3 pounds of moisture per hour; and
  • A dehumidifier with a 10,000 Btuh capacity will remove 10 pounds of moisture per hour

How to Reduce Running Costs

  • Use a dehumidifier with a low power consumption. The higher the wattage, the more expensive it will be to run. If you can find one that runs on less than 25 watts, you should be able to reduce your running costs significantly by using this model instead of one with a higher power requirement.
  • Don’t leave it on for longer than necessary. It’s common practice to leave your dehumidifier running while you’re asleep or away from home; however, doing so can damage its components over time if they aren’t properly taken care of after each use (see “How Much Does It Cost To Run A Dehumidifier For 24 Hours” above).
  • Don’t use it in an area where there’s direct sunlight coming through windows or doors—this could cause overheating issues which could lead not only directly affect how long before needing servicing again but also potentially cause other problems such as electrical shock as well as increased risk for fire hazards within homes due specifically designed around keeping things cool enough without breaking down too quickly.”

Our table has outlined the rough cost of running a dehumidifier for 24 hours and it’s dependent on what size you have. With the average dehumidifier taking up about 18.9 watts when running, this means that 7000 BTU unit will cost around $0.92 a day to run for 24 hours.

To give you an idea of how much your dehumidifier will cost to run for 24 hours, we’ve outlined the rough costs below:

  • A 700-watt unit would cost about $0.92 a day to run for 24 hours, assuming that it’s operating at 70% capacity (which is actually more than most).
  • An 800-watt unit would cost around $1.21 per day to operate in its full capacity (assuming it’s operating at 90% capacity).


We hope this article has been helpful in calculating the cost of running a dehumidifier for 24 hours. This is a rough estimate and will depend on what size you have, but it gives you an idea of how much electricity will be used per day, week and month.
