Despite all the silly schemes and logic the simple answer for 99% of the people
is to increase their air circulation.

This gets the moisture throughout the house where it may be desired and heat the
basement more so the rH drops.

Moisture in the basement is only a sign of air stratification and does not
indicate leaks. Only higher rH due to cooler air and condensation.

If your basement is damp in the winter time, *thats* a sign of a poorly
waterproofed/sealed basement foundation/floor. The only time you should
have trouble with damp basements is summer, when the warm moist air from
outside finds its way into the much cooler basement (RH goes up in the air
as its cooled, making things 'feel' damp/clammy), -or- when the foundation
is below the water table and not properly sealed. How does a 50F 100%RH
weather outside make a basement 'damp', unless the basement is even cooler??

Those in Pacific northwest obviously have a different issue, but for most of
us the dehumidifer gets shut off in the winter as there isn't enough
humidity in the air to condense (unless your dehumidifier works down in the
30F range)
