It was easy to install with the optional hanger kit. Lowered the humidity from 78% to 57% in less then 24 hours. Runs quiet can only hear it if the TV is off and you listen real hard from inside the house.

I had a high humidity problem in my crawlspace, over 81%. I looked at several products, but settled on the Moisture Medic (rebadged Aprilaire 1820) with the 8082 communicating thermostat. I'm glad I did. I installed it and in one day the moisture level dropped 18 pts to 63%. After sealing the vents around the crawlspace and letting it work, the humidity level now stays around 55%, this morning it was 52%.



The installation wasn't without issues, but Crawlspacerepair.com was great to work with. I worked with Larry to get it setup. The remote sensor (humidity and temp) would not work. It turned out I needed a separate 24 AC transformer (similar to the one for the fans) as the Moisture Medic 70 supplies 30v DC. Found a 24v AC 20VA (10va min was recommended), installed it, connected that to the thermostat and the system worked. I can now monitor/set the humidity level on my phone. This is the most cost effective solution out there!

Question..How far does the sensor have to be from the unit? My crawl space is approximately 3,000 sq ft. to get an average reading?

good dehumidifer

I've had my Moisturemedic installed now for about 4 months. Our crawl space is already encapsulated, and we have sealed off the foundation vents. Our house is about 1800sq ft. I bought the 70 pint version. So far this little unit has done the job very well and keeps the crawl space humidity right at 50% confirmed with an external humidistat. I took the sides off the unit to look at the guts and it is a simple design that would be easy to clean if the need every arises. The drain is completely on the bottom of the unit unlike the old unit I am replacing which kept getting clogged with algae. I was able to plumb the drain line into the 2" shower drain line just upstream from the p-trap so that that the shower will keep water in the p-trap. The dehumidifier is quiet and is clearly made by Aprilair.
