Question: Why Is My Dehumidifier Blowing Out Hot Air

Warm or hot air coming from under or behind the dehumidifier is normal and part of the dehumidification process as long as the unit is drawing moisture from the air. When the unit is dehumidifying, the compressor is generating heat as it operates.

Should the air coming out of a dehumidifier be hot or cold?

The air temperature coming out of a dehumidifier should be at least 50 to 59 degrees Fahrenheit higher than the initial air. Like I said earlier, the air passes through the heating coils before it’s ejected from the dehumidifier. The heating coils warm the air slightly before releasing it into the atmosphere.

Why is my dehumidifier making my room hot?

Yes, dehumidifiers naturally create a small amount of heat as they operate. But most customers don’t notice it for a few reasons: (1) it’s a very slight increase and (2) since dehumidifiers remove moisture from rooms, they naturally make rooms feel cooler and more comfortable.

Do dehumidifiers cool air?

Dehumidifiers remove excess moisture in the air by drawing it in from the outside and cooling it. A refrigerant (or compressor) dehumidifier draws in air. While they remove humidity, neither type of dehumidifier won’t noticeably affect the temperature of a room. However, removing humidity may make the room feel cooler.

Should a dehumidifier compressor get hot?

Running a dehumidifier in endless humid conditions can cause the unit to run non-stop and cause compressor overheating. Most dehumidifiers are designed to work at a room temperature of 65°F or above. Temperatures below 65°F can cause the coil to get too cold and freeze up.

Should a dehumidifier run all the time?

Should a Dehumidifier Run Constantly? No, there is no need to keep the dehumidifier running constantly. It’s generally enough to run the unit when the humidity level is 50% or higher. A good rule of thumb to remember is to maintain a comfortable 30-50% humidity level for most homes.

Does a dehumidifier heat the air?

To be clear, dehumidifiers are designed to remove moisture from the air, not cool it. There’s also some additional heat generated by the dehumidifier’s air compressor. The overall result is that the air going back into the room might be warmer than it was going in, usually around 10 to 15 degrees.

How many degrees will a dehumidifier cool a room?

Requirements for a dehumidifier to cool a room You should also consider the temperature of the environment. Some dehumidifiers cannot run in low temperatures, while others can. On average, most dehumidifiers work best in temperatures from 70 degrees Fahrenheit and higher.

Can I use a fan and a dehumidifier at the same time?

The simple answer is Yes. You can use a fan and a dehumidifier at the same time. The fan creates a strong breeze, displaces the air in the room and helps to ensure the dehumidifier can collect more air from the room and drain them of moisture. Also, you’ll not just have the dry air you desire, but a cool one as well.

What should I set my dehumidifier at?

You should set the relative humidity (RH) level of the dehumidifier between 30 to 50%. Many people reported 45% as an ideal relative humidity level. This percentage can be increased or decreased depending on your comfort level and your home’s needs.

How do I know if my dehumidifier compressor is bad?

Humidity will not reach the set point If the blower in the dehumidifier is running it is possible that the compressor is not operating. Check to see that the indicator light, on the dehumidifier, is confirming that the compressor is operating. If the compressor is not running call a competent HVAC company for service.

How hot should a dehumidifier get?

Ideal Dehumidifier Operating Temperatures. The ideal operating temperature for refrigerant dehumidifiers is between 70 and 90 degrees F.

Is a dehumidifier a fire hazard?

“The recalled dehumidifiers can overheat and catch fire, posing fire and burn hazards,” according to a notice posted earlier this by the U.S. Consumer Product Safety Commission.

How do I know if my dehumidifier is working properly?

Hygrometers are inexpensive and readily available. Set the humidistat at the appropriate level; usually, we recommend around 35% relative humidity. After the dehumidifier has run for around an hour, check the reading on the hygrometer. If the unit is functioning the display should tally with the setting.

Why do dehumidifiers have to be upright?

Why does the dehumidifier need to be to be upright 24 hours before running for the first time? It’s necessary for the oils in the compressor to settle before turning the unit on, not doing so can affect the performance of the unit.

What are the disadvantages of a dehumidifier?

Con: Noise and Heat Dehumidifiers also tend to blow warm air out of the back of the unit. In the winter, this can be an advantage — but not so much in the summer. Position the back of your dehumidifier in a doorway so that it doesn’t heat up the room from which you are removing excess moisture.

Will a dehumidifier make my house feel warmer?

Will a dehumidifier make my room warmer? Dehumidifiers work much the same way as air conditioners, however unlike air conditioners, a dehumidifier does not cool the air. The smaller the room, the more the air temperature will be raised, while in a large area, the effect is usually negligible.

Do dehumidifiers use a lot of electricity?

Dehumidifiers use energy (some more than others), but they can also reduce energy consumption in other ways. They are also the fastest way to reduce humidity, which has a range of benefits.
