A room with humidity feels uncomfortable and suffocating, and a dehumidifier is seen to make the room feel cooler and more comfortable. A dehumidifier is an invention that has made lives easier and more advanced. You do not need to put on big fans or let your windows left wide open to get humid free air. Just put a dehumidifier near a window a let it show its magic!
There are multiple types of dehumidifier for every size of the room and if you’re experiencing prominent heat in your room you probably need to check your dehumidifier or question your choice!

Which dehumidifier can be the reason behind the heat in the room?
If you live in the southern half of the United States, particularly if you live in Texas or Florida, you’ve probably spent at least some time watching the temperature on your thermostat rise while your air conditioner struggles to keep up with the heat outside. So, do dehumidifiers heat a room? We decided to find out!
In this article, we’ll explain how dehumidifiers work, how they can help cool your home, and what steps you can take to stay comfortable while using one in your home.
As we have said earlier, dehumidifiers are of multiple types, and one that heats your room could be a desiccant dehumidifier. The built-in heating element in the desiccant dehumidifier regenerates the desiccant gel, the heat produced is not lost, neither it is absorbed by the gel. It throws in all the warmed-up, moisture-free air into the room and the temperature of the room rises with a noticeable change. The temperature of air blown into the room ranges from 7 degrees to 12 degrees elevated to the ambient temperature.
Dehumidifiers sometimes heat the room for the following reasons;
- If the room is too small for the dehumidifier
- If it is left on for a long period at a constant place
- If it is a desiccant dehumidifier
Different sizes for different spaces!
Dehumidifiers are available in different sizes for example for a large space you would be recommended to put on a larger dehumidifier as compared to a small space where a smaller dehumidifier would be perfect. Installing a large dehumidifier in a small space would result in unwanted heat. Also, prolonged placement of a dehumidifier in one area can heat the space.
Do dehumidifiers heat a room?
It’s a common question—but you may be surprised to learn that there’s not really an easy answer. It depends on so many factors, including what size your dehumidifier is, where you place it in your home and how long you run it for each day. We’ll explain what we learned when we tested various models of humidifier in an attempt to see if they do indeed warm up your home. But first, let’s talk about why a dehumidifier warms or cools a room.
As most people know, these appliances draw moisture out of air by pulling it through their condenser coils (or evaporator coils). The coils use fans to move air over them. In some cases, water collects inside coils; other units are designed with separate tanks or reservoirs that collect water from condensation instead. As air passes over cold metal coil surfaces in either case, moisture from within will condense into liquid form as it comes into contact with cooler temperatures than those found within your home’s atmosphere.

Don’t Leave the Fan On All Day
A lot of people believe that dehumidifiers can cool down an entire room, but that’s not entirely true. The cooler air created by these machines does indeed make for more comfortable temperatures, but it doesn’t raise them to a desirable level. You should always turn off your dehumidifier when you leave your home or office so it isn’t running while you aren’t there to enjoy its benefits.
If you don’t do so, your machine will continue to pull moisture from the air and release warm air into your space. This will create a backdraft effect that could potentially cause mildew and mold growth in your house or business. If you want to keep things as clean as possible, remember: Turn off dehumidifiers when they aren’t in use!
Keep a Mist Humidifier in Your Bathroom
Do dehumidifiers heat a room? It depends on how hot your room is. Keep an eye on things by keeping a mist humidifier in your bathroom. You won’t risk over-chilling yourself, and if you see that condensation forms on your windows or mirror at night—don’t sweat it. It’s totally normal. Just be sure to use distilled water to prevent mineral buildup from messing with your equipment. Plus, keep your door closed so you don’t lose all of that moisture into your hallway.
It can also help to keep a window cracked open for ventilation (but be careful not to let any bugs in). If there are any vents near where you have your humidifier set up, make sure they aren’t blowing cold air directly onto it (you’ll want them pointed away from it). And finally, do not use tap water when filling up any part of your humidifier—always use distilled water instead to avoid mineral buildup and potential damage to internal components.
What Not to Do with Your Dehumidification Machine?
Many people think that because a dehumidifier takes moisture out of the air, it must also take heat from that same room. A general rule of thumb is that one can remove four to five times as much heat from an area using dehumidification than through simple ventilation. This means that for every 100 BTUs/hour produced by your dehumidifier, you could also theoretically remove an additional 300 to 400 BTUs/hour of heat by removing moisture from within a room.
The amount of energy needed to do so depends on several factors including: The efficiency rating of your unit, The volume of water removed from a given space and the temperature difference between inside and outside.
For example, if you were trying to lower humidity in a 1,000 square foot space with an average temperature differential between inside and outside (20 degrees), then you would need roughly 2 kilowatts per hour (kWh) in order to maintain temperatures at or below 80 degrees Fahrenheit. If there was no temperature differential between inside and outside (for example: 70 degrees), then only about 1 kWh would be needed per hour instead.
Can a Dehumidifier be used in summers?
It is best to use a dehumidifier in summers as the atmosphere is most humid in the season. It helps in making your surroundings more comfortable and less muggy and also favorable to your skin. The air is improved and made free from allergens such as mildew and mold.
Does the dehumidifier heat the room?
A dehumidifier generally creates a very small amount of heat which is usually negligible and does not change the temperature other than adding a bit of warmth to the space. But some dehumidifiers are made to throw heated air after removing the moisture.
How do dehumidifiers work?
Dehumidifiers are an excellent aid to remove the moisture from the air and it saves so much energy. How? Without a dehumidifier, you would need to switch on your fans for hours which will only add figures to your electricity bills.
Dehumidifiers suck in the humid air and remove all the moisture from the air, in a way that no traces of air are left behind. The dried air is then thrown into the room making the atmosphere more comfortable and admirable.
Dehumidifiers are not meant to add to the heat in your room instead they contribute to cooling your room. They are made to exist to eliminate the moisture content from the air. This elimination makes the air allergens-free and more comfortable.
The answer to the question “Does dehumidifier add heat to the room?” is that a dehumidifier doesn’t add heat to the room except for a desiccant dehumidifier but a dehumidifier can be the reason behind a comfortable warmth.
