Would a dehumidifier in a basement change the temperature of the room/basement?
My basement is hot. I'm wondering if the dehumidifier is warming it up.
Yes. Or maybe. It depends on what ventilation or circulation practices you have in place.
A dehumidifier works by cooling a coil, on which water vapor then condenses. In order to cool something, you usually have to heat something else. In this case it's ultimately air exhausted out the back or side of the unit, just as with a refrigerator. This can raise room temperature if you don't have air circulation preventing it.
However, in my experience the net effect is a wash. The feel of dryer air is cooler, so even if the room warms a degree or two, it'll feel the same or cooler due to the improved function of body sweat.
A dehumidifier converts vapor to liquid water - that releases heat.
It also has a electric motor that also releases heat.
It's basically the inverse of a swamp cooler.
Yes for sure. The more the humidifier works the greater the energy output. Unless it is dissipating the energy out a window and in only in that direction your basement will be warmer.
In a closed basement if you run fans continuously it will get warmer. We have ran fans to get rid of water and if the thermostat is on the first floor it is quite normal for the basement to be 2-3 degrees warmer after a day of running heavy fans.
Yes, the dehumidifier compressor will exhaust heat in the room. However not much, more like a 150 Watt light bulb.
The main change in the temperature will be in the Feels like
They have "Feels Like" in the weather forecast.
