How the Humidity Gets Into Your Home

When your home was built it involved lots of wood and holes drilled through it for plumbing, HVAC, etc. Over time, your home starts to expand and contract and the tight seams began to warp, and more openings begin to appear. There are lots of openings between your first floor and your crawl space, which lets in the most amount of air as the warm air rises through your whole house, to leave through the attic.

The Function of a Crawl Space

A crawl space is not a replacement for a basement, most have dirt floors and some are only about one to two feet tall. When a crawl space is waterproofed it can also be a useful storage area. The original purpose was to provide air circulation while giving access to plumbing, electric, and HVAC. However, many crawl spaces are vented which brings in more outside humidity than air circulation.

Energy Efficient

Closing off crawl space vents has become an increasingly popular suggestion from professionals to homeowners. Almost 40 percent of the air circulating in your home comes from the crawl space, so you can understand how much of an improvement sealing vents could make. A closed off crawl space also increases energy efficiency by limiting the influence of the outside climate.

Dehumidify the Space

  1. You must close off vents first, otherwise, the dehumidified air will be replaced immediately by more outside air.
  2. Install a self-draining dehumidifier because one with a collection tray could fill up and shut down in as little as 12 hours.
  3. Make sure it is a powerful dehumidifier that is sure to keep things dry all the time.
  4. It’s got to be energy efficient.

This self-draining crawl space dehumidifier has a unique heat exchange system that operates at the optimal temperature of 40 degrees to 95 degrees, helping it achieve an Energy Star rating. It can remove up to109 pints of water per day without needing the collection tray emptied. It simply empties into a sump pump, dry well, or a special condensation pump to discharge the water outside. The large cold coil surface helps it handle a 6,000 square foot crawl space, at 3 feet high and adjustable knob lets you choose the level of dryness — all you have to do is set it and forget it!
