Dehumidifiers are a must-have to regulate the plaguing humidity of a basement. Basements tend to have higher humidity levels than the rest of the house. In the absence of a dehumidifier that helps maintain the appropriate moisture level of this underground facility, molds start to form.
However, the usefulness of dehumidifiers depends on multiple factors. The outdoor weather and the indoor temperature are the two most significant factors that come into play when determining the need to use a dehumidifier. That leads us to our question, is running a dehumidifier in the basement okay in winter? Let’s learn the answer below.
2 factors to keep in mind while deciding whether to run a dehumidifier in the basement in winter
Dehumidifiers are known to not function well at lower temperatures. A temperature below 65 degrees Fahrenheit puts the coils of the dehumidifier at risk of freezing.
In areas where the ground freezes in winter, the moisture seeping into the basement from the ground and windows will reduce drastically and might even bring the need to run a dehumidifier to a negligible level. However, that isn’t always the case, especially in temperate regions.
The need to run a dehumidifier in the basement in winter depends on the following two factors:
Factor #1: Basements without a heating system
If your basement doesn’t have any sort of heating system in winter, then the temperature might drop below 65 degrees Fahrenheit. In this case, the dehumidifier will not function properly, and running it would be a waste of energy.
Factor #2: Basements with a heating system
Is your basement is equipped with a central heating system in winter? Then it’s likely that the warm air from the heater will lower the moisture level of the air significantly.
Due to the increase in temperature of the basement, the dehumidifier would now be able to function properly. However, you should keep the following two points in mind when deciding whether there is a need to run the dehumidification process:
Monitor the humidistat regularly to determine the level of humidity in the basement; if it is 50% or lower, then you don’t need to keep it running
Keep an eye out for molds in your basement
A regular home dehumidifier is usually designed to work at indoor temperatures above 65 degrees. Therefore, they might become ineffective in winter and it will be a waste of money to invest in one at this time.
Meanwhile, there are dehumidifiers in the market specially designed for basements and lower temperatures. It could feel like an added expense, but with a weather-specific dehumidifier, you will be able to regulate the moisture level of your basement in winter and reduce the dampness efficiently.
