Dehumidifiers are becoming increasingly popular in the home. They help regulate the moisture in the air, which is beneficial to your health and well-being and can also help prevent moisture damage to your home and belongings.
Dehumidifiers have many different uses, but people often ask, does a dehumidifier cool a room? In this article, we’ll help to explain what a dehumidifier does and doesn’t do and whether it can be used to cool your home.
What Does a Dehumidifier Do Exactly?
A dehumidifier’s primary purpose is to remove moisture from the air. They do this by drawing air into the dehumidifier, removing the water vapor, and then releasing it back into a room. The moisture gathers in a tank so it can be emptied afterward.
Dehumidifiers are often used in specific locations or rooms within your home that have more moisture than others (like basements or cellars). They’re particularly effective in hotter climates with higher levels of humidity which, if left unchecked, can damage your home and belongings.
Dehumidifiers are great tools to help you control the environment in your home effectively and can have a range of additional benefits if used correctly.
Does a Dehumidifier Cool Your Room?
There’s a lot of debate and discussion about the impact a dehumidifier can have on the temperature of a room, and it isn’t exactly straightforward. The quick answer is that yes, it can make a room feel cooler, but no, it won’t technically cool it down.
Every single electrical device in your home gives off some heat and will contribute to the overall temperature in a room or area. Usually, you have ventilation of some kind to counteract this, but dehumidifiers only work in rooms with no ventilation.
This means that if left running, your dehumidifier will actually have the opposite effect and will make the room hotter.
However, almost every homeowner feels that a room becomes cooler when you run a dehumidifier, so what is happening? This is all to do with the moisture in the room and our physiological reaction to heat.
When we’re really hot, we produce sweat that is evaporated from our bodies to get rid of the heat. In a humid environment, this sweat can’t evaporate because the air is too wet already. Still, as the dehumidifier works and the moisture is removed, we can cool down more effectively.
The temperature in a room may rise by 0.5 degrees Fahrenheit while the moisture goes down by 40%. So, in crude terms, a dehumidifier can make a room warmer, but you will get cooler.
What Can Affect a Dehumidifier Cooling a Room?
A dehumidifier needs to be set up correctly to help you feel cool in a room. There’s a couple of variables that will impact how effective it can be:
The dehumidifier you choose should be suited to the size of room it will have to operate in. Dehumidifiers are rated on the amount of moisture they can take from the air and how this relates to the square footage of an area.
If you choose a dehumidifier that’s too small, then it won’t be able to remove the moisture and make the room feel cooler– too big, and it could make the air too dry. Make sure you measure the room correctly and choose the right model for the job.
Temperature In Your Location
Different dehumidifiers have different temperature requirements. The majority will work best at 70-80 degrees Fahrenheit, but it’s worth checking the manufacturer’s specifications. It’s also worth remembering that some dehumidifiers can’t work in freezing conditions, so if you live in a very cold climate, then you’ll need a specialist model.
It’s important you put the dehumidifier in the right location so it can cool a room effectively. If you have spots in your home where you know there’s higher humidity, then direct the dehumidifier there. If not, then make sure you position it right in the center.
Cooling A Room Using a Dehumidifier – How To Do It?
Here are the steps you need to follow and some tips to cool a room using your dehumidifier:
- Set Up the Dehumidifier
Place your dehumidifier right in the center of a room. This will allow it to remove the moisture more effectively and give the best cooling effect.
- Set the Device
You need to set the humidifier based on the humidity in your home.Some models have a gauge built-in, but you may be best off buying a hygrometer so you can understand the current moisture level. The manufacturer’s guide will give instructions on how to set the device, but the higher the humidity, the higher you’ll need to set the machine.
- Seal the Room
As much as possible, you need to seal the room so the humidifier can work effectively. Close all windows and doors so that it’s working in an area that it can comfortably handle.
- Maintain the Device
Your dehumidifier will gather water in a tank, which needs to be emptied periodically so it can continue to function. If you have higher humidity levels, you’ll need to do this more frequently, but you should check the device every day at a minimum.
Dehumidifiers are programmed to turn off when the humidity levels reach a certain level. This helps to stop the air from becoming too dry. It can be better for your health (particularly your skin) if you switch it off at night, but if you’re leaving it on, make sure it’s programmed to switch off before it becomes too dry.
Should You Keep Your Dehumidifier Running All Summer Long?
Dehumidifiers are generally more useful in summer when humidity levels reach their peak. Most dehumidifiers are designed to be left on for long periods, but that doesn’t mean you should just leave them running 24/7. This will depend on the climate and the conditions it’s being used in.
Generally, dehumidifiers should be left on for at least 12 hours to manage the moisture levels in the air. This helps to prevent your air from drying out and enables you to limit the amount of money you’re spending on energy to power it. It’s worth getting a hygrometer to measure the moisture levels in the air so you can determine how much you need to use a dehumidifier.
If you live in a particularly humid area, then you may need to leave it on for longer, so it’s worth investing in an energy efficient dehumidifier.
Dehumidifiers can be left running all summer long but make sure you program it correctly so the air doesn’t become too dry. You’ll also need to empty it regularly, or it will switch off automatically. If your air continues to be very damp, then it might be worth exploring the issues causing the humidity, like leaky pipes or broken window seals.
People Also Ask (FAQ)
Can I use a dehumidifier instead of an air conditioner?
Air conditioners are used to remove the moisture and heat from the air in your home. Dehumidifiers are only designed to remove moisture and shouldn’t be used to replace an air conditioner. Dehumidifiers are often used in conjunction with air purifiers & air conditioners, but a dehumidifier on its own won’t have the same effect.
Should you run a dehumidifier and air conditioner at the same time?
Generally, dehumidifiers and air conditioners don’t need to be used at the same time, and the air conditioner will only turn on when the temperature becomes too high. However, running both together can lead to a spike in your energy bills.
Is it cheaper to run a dehumidifier or an air conditioner?
Dehumidifiers are generally less expensive to buy than air conditioners and use less electricity to run, making them cheaper all around.
Will a dehumidifier help with heat?
A dehumidifier won’t actually cool a room, but it will make it feel cooler to everyone in it.
Technically speaking, dehumidifiers won’t actually cool a room, but the way they operate they will make a room seem cooler. Hopefully, this article has helped explain what that actually means and has given you some useful tips to set up your dehumidifier correctly to maximize the cooling effect.
