Crawl Space Dehumidifiers

What You Need To Know About Dehumidifiers for The Crawl Space

Not all crawl space dehumidifiers are made to work in the crawl space, in fact most are not. Light duty dehumidifiers fail in a short period of time because of the consent demand on them to remove moisture and condensation. Spending a little more on a commercial grade dehumidifier will yield better results and extend the service life up to 8-10 years instead of 8-10 months.

The Real Cost of Saving Money

If a $200 dehumidifier lasts 10 months it will cost you $16.60 per month (divide cost of unit over life span) but a Moisture Medic® 70 pint dehumidifier would only cost you approximately $9.95 a month using the same ROI (return on investment) calculation. Almost every one of the .2% (.002)of the Moisture Medics® that need repair or replacement (in the 10 year window) happens during the 5 year bumper to bumper warranty period.

Selecting the correct size is very important to the performance and lifespan of the dehumidifier.

Crawl space dehumidifiers come in many sizes depending on your homes needs. Selecting the correct dehumidifier depends on the volume of air in your crawl space. Bigger is not better! When a dehumidifier is too big for the space the on board controls will work against the productivity of the dehumidifier. One of the byproducts of running a crawl space dehumidifier is heat. Heat is not a bad thing when it is winter, but it is not a good thing when you are removing moisture from the air with a dehumidifier. Relative humidity is affected by two things; air temperate and dew point temperature. When the dehumidifier gives off excess heat, that heat will lower the relative humidity and can turn the dehumidifier off. Larger than needed dehumidifiers in a crawl space will create that excess heat and cause the dehumidifier to run short cycles...eventually shortening the life of the dehumidifier. Properly sizing a dehumidifier for your crawl space will ensure you get the lifespan you expect. If you need help with sizing your crawl space dehumidifier, please give us a call 864-223-7800.
