Crawl Space Dehumidifers

When it comes to crawl space dehumidifiers, quality means everything. A good high quality dehumidifier in the crawl space is extremely important. Unfortunately for homeowners, there’s several out there that just doesn’t perform the way you need. In the end, you’re left with a system that doesn’t work and a large bill to boot.

Do I need a dehumidifer in the crawl space?

Truth be told, there’s a lot of different things that could be going on in your crawl space. Most crawl spaces need dehumidifiers, at least if you want to fully control your crawl space. A lot depends on the type of climate you live in. The more wet and humid it is, the greater chances you’ll need a crawl space dehumidifier.

The typical number we use to guide us is 55. If your dew point is above 55, you should get a dehumidifier. This is the type of climate we consistently see down south and in the Midwest.

What happens if I don't get a dehumidifer?

Remember the purpose of the dehumidifier. It’s used to create proper air flow and proper water removal. The biggest scare of not having a dehumidifier has to be mold and mildew. Black mold is one of the biggest. Black mold can grow in a wet moist area of your crawl space. And if you don’t know, black mold can kill you.

There are two tools that will tell you what you will need, a hygrometer and a dew point calculator, both offered by CrawlSpaceRepair.com. You can use the hygrometer to keep an eye on the humidity in the crawl space with its wireless remote and use the dew point calculator to know how to adjust the crawl space environment with either dehumidification or a raise in temperature.

 

Crawl Space Dehumidifier Sizes

 

 

One of the most important elements when choosing your crawl space dehumidifier is ensuring that the dehumidifier you choose is capable of correctly working for the size of your crawl space. If your dehumidifier is not big enough, it defeats the purpose. So one of the most important rules is making sure your crawl space dehumidifier is capable of properly working for your crawl space area.

Not all crawl space dehumidifiers are created equal. You have to pay attention what your dehumidifiers are capable of. Just because a dehumidifier is priced higher does not mean that it’s better.

The key to proper dehumidification covers two important aspects, proper air flow and proper water removal.  First, you need proper air flow for the system to work. Secondly, you need proper water removal. Think about this,  If you can’t get your crawl space’s air moisture to the crawl space dehumidifier, it won’t matter how much water it removes.  Pints per kilowatt hour (P/kWh) or Liters per kilowatt hour (L/kWh) will determine how efficient your unit is, so always pay attention to that.
