Crawl Space Dehumidifier

Crawl Space Dehumidifiers

During summer, when it’s hotter outside than inside, high humidity in a crawl space is common. Condensation forms as warm, damp air infiltrate your chilly crawl area.

This is because cold air cannot store as much moisture as warm air, causing humidity to rise. Leaking pipes or a lack of insulation in your crawl space can contribute to humidity levels.

Crawl space dehumidifiers are more compact due to the limited space. A more powerful fan is also required for crawl space dehumidifiers. This guarantees that dry air travels around narrow places and corners.

For these reasons, if you’re going to use a dehumidifier in your crawl space, make sure you choose the right one.

When placing a dehumidifier in a crawl area, make sure it is in the right place. You want to make sure the dehumidifier has the most surface area to exchange air with.

Using a fan to circulate air around your crawl space may be helpful. Moving air around in confined spaces helps with dehumidification.

If your dehumidifier does not have a continuous drain, you will need to empty the tank. If you’re collecting water in your dehumidifier’s tank, make sure it’s accessible. [1]

Does A Crawl Space Dehumidifier Works?

Crawl space dehumidifiers work to remove water in the buffer between the wet ground and the living areas in the home above.

Crawl space dehumidifiers are compact enough to fit in small tight spaces. They are still very efficient with a humidistat to set it to the desired humidity level. A defrost function will prevent the coils from freezing.

Where Should I Place A Crawl Space Dehumidifier?

If you have a narrow storage or utility space in your home or office, a crawl space dehumidifier is a great solution. It makes that space a little more pleasant when it needs to be accessed.

Crawl spaces are often poorly insulated, and rarely accessed. They are usually only used when there is a problem elsewhere in the structure. This makes them vulnerable to the elements, promoting mold growth and allowing in air that will encourage excess indoor humidity. It also means that by the time you notice a problem, it could have progressed quite far.

Controlling the humidity in your crawl space also makes the environment less favorable to pests, including insects that thrive in high humidity areas.

Dehumidifiers placed in a crawl space perform two specialized functions to work most effectively in that particular space. Look for one with a strong fan to push air throughout the entire space and one which is compact enough to fit in this cramped area but still allows airflow over the whole unit.
