Dehumidifier upgrade

[vangonebuy]

Hello to all,
New to Ecomodder. Enjoyed what I've read. Great stuff.

My old dehumidifier isn't cutting it.
New dehumidifiers are now judged by Liters per Kwh.
Time for a test.

Before I went to spend new money, I decided to test my old one.
So I ran 3 different tests.
It ran for 2 hours with a Kill a Watt meter attached.
Drained it after a wait. And measured the water with an old kitchen measuring bowl.
Results were averaged. In basement.
2.04 Kwh
1.37 liters= .67 L/Kwh
(liters / Kwh)

Now the new dehumidifiers are rated in L/Kwh.
See attached link:

I chose a 1.6L/Kwh 50 pint GE unit. It was a great price. Although a 1.8L/Kwh is a better unit. The extra $50 didn't seem worth it.
And the payback is kinda small .

What was interesting was that the difference of basement cooler temperatures had on output.
While the new GE was averaging 1.56- 1.6 L/Kwh upstairs in warmer temps.
In the basement it was reduced to 1.38. Still, At least a double.
I'm now testing downstairs at different fan speeds. To get max out of it.
But, So far it's much much dryer and hopefully cheaper.

Interesting stuff. We don't have humidity problems in California. My only experience with dehumidifiers was in Acapulco. We turned one on in our room, went to dinner, and came back in 2 hours to find the 2.5 liter unit almost full to the brim with water it had removed from the air.

Your basement results don't surprise me. Cooler air holds a lot less moisture than warmer air does. We used to add humidity to our home in the winter in Utah. There was a humidifier pan in the heating unit.

I have this same type of setup where we add humidity in the winter. I moved into my house with little guidance on how to use this. I had an HVAC technician come out, and it is very simple! I not know how to change the necessary humidifier parts to make it work properly. It does help keep it warm!

We've found (several people with whom I've asked with classic cars) in hot & humid South Texas that a cheap window A/C uses not so much more electricity than a fair sized dehumidifier with the benefit of cooling the room (attached garage, not basement as we have none here). Drawback is wall-mount (cut hole).

I empty better than 2-gls day from my portable garage dehumidifier at present. Garage door not in use.
