Does a dehumidifier heat a room? Explained (2022)

Does a dehumidifier heat a room? It’s a commonly asked question many potential buyers have.

Yes, but only slightly.

To better understand the answer, it helps to know a little bit about how a dehumidifier works.

The dehumidifier has one basic job and that is to “de-humid” or reduce the level of humidity in a space, room, or house.

Here’s a great video to better explain how a dehumidifier work.

However, you are not likely to notice this warmer air since it is only slightly warmer than room temperature. In addition, by removing the moisture from the air, the treated area will feel cooler.

The warm air coming from the dehumidifier is actually the treated air with the moisture removed.

The process of dehumidification starts by pulling air into the unit. At this point, the air is chilled to remove water from the air, and heated to remove additional moisture before being blown back into the room.

The majority of dehumidifiers function by sucking air from the room over a coil that has been chilled to a very low temperature by a refrigeration system.

Refrigeration dehumidifiers are what they’re called. The liquid water drips into the water collection bucket underneath as the water vapor condenses on the chilly surface.

Desiccant dehumidifiers are becoming more popular as an alternative to traditional dehumidifiers. Desiccant dehumidifiers circulate air over a water-absorbing material-coated wheel ( called a desiccant).

The water is removed from the desiccant by blowing heated air through it, which dries it out and regenerates it so that it may gather more moisture on the next pass. The collected water is stored in the water collecting tank of the unit.

How does a dehumidifier prevent mold and mildew?

Second, the air is too dry for mold and mildew spores to form if the dehumidifier is adjusted to maintain relative humidity at 50 percent or slightly below. Fungi require both airborne and surface water to thrive.

Can a dehumidifier be used for cooling?

Does a dehumidifier help to keep a house cool? The same concept applies to a whole house, much as dehumidifiers don’t technically cool a room but might have a cooling impact due to the reduction in humidity. The important thing is to get a device that can cover a large area.
