I have a 90 Pt Dehumidifier in the encapsulated crawlspace of a 1700 sq ft ranch (house). The home is in a cool, shady forested area that sees quite a lot of rain (and there is a lot of groundwater). If not for humidity, you could probably not even have air conditioning. The water runs out into a small pump/reservoir like you would use with an air conditioning system and is automatically pumped outside when the small reservoir is filled. The dehumidifier has a humidistat and runs pretty much continuously. It makes a big difference in humidity levels and doesn't seem to cost a lot to run.
