Default Crawl Space Moisture

I am sealing my crawl space and putting down a vapor barrier but was also going to put in a dehumidifier. I was looking at a unit by Seaira Global and wanted to know what you guys thought. I searched and asked on a couple forums and am just trying to get the most opinions about it.

Do you guys have any thoughts on this unit:

The crawl space is about 7,000 cubic ft. Not very big.

Please tell us more about the crawlspace.

is there an odor problem or "wet windows" problem you're trying to solve ?
is the crawlspace floor dirt, gravel ... ?
is that floor always wet ?
what are the crawlspace walls constructed of ?
are there foundation vents in the crawlspace walls ?
are there gutter downspouts that empty near the foundation ?

thx,
Ed

Have you solved all problems with water getting in?

Did you read the comments to your earlier identical post on HVAC? It is better to ask additional questions on the original post rather than creating duplicate identical posts.

Are you making your crawlspace conditioned and closing all the vents to the outdoors and insulating the exterior walls? If you leave the vents open and put in a dehumidifier you're going to try to dehumidify your neighborhood. Here in NC, I know that is impossible.

Do some research on a conditioned crawlspace. It is a good idea but needs to be done correctly or you can cause more problems. Covering the floor is always a good idea.

I had damp ground and walls in the crawl space.

Concrete block walls

yes there are vents that I was going to seal.

There are but they run away from the house.

I am going to put a vapor barrier and seal the vents. I believe that will solve that problem.

There's some good info here:
http://www.houserepairtalk.com/showt...ing+crawlspace

...and some other threads, as this discussion comes up occasionally. Do a search for crawlspace or sealing crawlspace.

You posted them both in the same HVAC section of the forum.
