I am looking for a low power consumption dehumidifier to cut costs. I
seen these 2 below that use only a couple hundred watts compared to
mine which uses 792 watts(30 pint). I have a 1000 Sq ft. house and
will have the unit in the basement. Would these work well. I would say
my house has the "typical"basement" . The surround air 510 says it
will remove 21 pints per day in the specs but 28 pints down lower in
the description? I used this formula to figure out I am spending
almost $60 per month to run my unit now which is 792 watts:

(watts/1000) x hours used x cents per kil. hour= operating cost
792watts/1000 x 24 hours (during summer) x10 cents(estimate)=$1.90
(24 hours) x 30 days= $57


With lower power consumption dehumidifier:

195 watts/1000 x 24 x 10= 47 cents x 30days= $14.10

Is this too good to be true or are these things marketing scams that
wont work well? Thanks a lot
