Choosing A Dehumidifier For Your CrawlSpace

1. Seal Your Crawl Space From Outside Air

In the moisture control business, we see crawl space dehumidifiers set up like the one shown on the left all too often. Notice the cans underneath the legs, placed there to keep it above the floodwater line.

This poor dehumidifier doesn't stand a chance! Two-foot floods aside, this system is up against a vented crawl space. As soon as it dries the air, new outside air is there to replace it, and it will never keep up. Your unit can't possibly work in a vented space, no matter how powerful it is. What a dehumidifier will do in a vented crawl space is run continuously, costing you a bundle in utility bills.

Before trying to dehumidify the space, install a crawl space sump pump if you ever have standing water in the space. You should also seal off the vents, and install a crawl space vapor barrier. This will limit the new air reaching your system, and giving your dehumidifier a chance to dry the space.

1. Install A Self-Draining Dehumidifier

Once you've installed your crawl space dehumidifier, you're probably not going to want to think about it again. However, if that dehumidifier includes a water collection tray, your dehumidifier may be full to capacity and shut off automatically in as little as 12 hours.

Who wants to go into their crawl space every day to empty a collection tray? Even in a clean, well-maintained space, it's a chore most people would pass on if they could. Our SaniDry CSB has got you covered. With a self-draining design, it can remove up to 90 pints of water per day in your crawl space, without ever needed to have its collection tray emptied.

It can empty to a sump pump or drywell, or a special condensation pump can be added to discharge the water outside.

1. Find A Powerful Dehumidifier

If you have a dehumidifier in your crawl space, and the area is still damp, musty, and moldy, then you can make an obvious conclusion: it's not doing its job.

Sometimes a crawl space dehumidifier will not stop the mold and rot in a crawl space, but it will slow it down a little. How much damaging fungus is acceptable in your crawl space? If the answer is "I don't want any mold or rot there!", then it's time for an upgrade.

The answer is not to buy a second dehumidifier! Twice the units means twice the noise, twice the electricity used, and very often, a crawl space that's still damp.

The SaniDry CSB is a crawl space dehumidifier that's strong enough for the job! Its powerful 240 CFM blowing motor will circulate air throughout your humid crawl space, drying everything out and keeping it dry all the time! Its large cold coil surface (see comparison in photo) helps it handle a 6,000 square foot crawl space, at 3 feet high. An adjustable knob lets you decide how dry you want your crawlspace-- just set it and forget it!

1. Make Sure It's Energy Efficient

Typical hardware store dehumidifiers can really tank up on energy usage! In many cases, these systems can cost you 10, 11 cents or more to remove a single pint of water.

One of the main reasons for this is the small cold coils that many dehumidifiers have installed in their system. They just don't have the power or efficiency to do the job the way it's meant to be, and as the homeowner, you pay for it.

Our SaniDry CSB Crawl Space Dehumidifier has a unique heat exchange system that helps it achieve an Energy Star rating! Water can be removed at a cost of about 3.3 cents per pint. Our system removes four times as much water from the air at the same energy usage (6.3 amps).
