dehums don't seem very efficient compared to acs. i added the kwh
consumed to the number of pints produced (/3.41) then divided by the
number of kwh to get a cop of 1.6 vs 3 or so (seer/3.41) for a good ac.

can we fix that with some newspaper or duct tape? :-)

the cold air exits with entrained water?
the duct tape might help with that as well.

sounds good to me.
