I got a concrete floor poured in my crawl space 2 weeks ago and I have installed a 65 pint dehumidifier to keep down the humidity. I have it set at 45% and the unit runs non stop since it says that it is 55% down there. Is it safe to assume that the reason that is can't get lower than 55% is due to the concrete. The unit is rated for 2500ft2 in wet conditions so this thing should be able to keep up, right?
Thanks. I was setting at 45% just to be safe. Turns out that I think that the sensor on the dehumidifier is bad. I put a digital and dial meter down there and it turns out that is it is less humid than the dehumidifier says. The DH will say 65% and I go check on it 30 minutes later and it will say 45 or 50 and then 65 again. I am returning and getting a new one.
