This one's a bit OT, but I'm hoping someone can help:

I'm buying a dehumidifier to help with a condensation problem in my 3
bed house. I've narrowed it down to the Amcor PLDM18 (see
http://tinyurl.com/2pwbvp) or the Prem-I-Air PRDHZ80U (see
http://tinyurl.com/2ooau4). The Amcor is based on normal compressor
technology, while the Prem-I-Air is based on a newer dessicant
technology. According to one of the companies I spoke to the Prem-I-
Air is probably going to be more effective for my purposes & has other
smaller advantages (eg quieter & lighter).

The company that recommended it did point out the possible downside
that it is a higher wattage (ie 620w vs 260w) but reckoned that it
could well work out at a similar cost in the long run, as it would be
on less. Is that likely?

Thanks,

Michael

Dessicant wheel dhs use around twice as much energy, and cost
more to buy as well. Their application is in situations where temp
is below 12C, conditions in which compressor types are
ineffective. Compressor is the choice for nearly all living
situations.

However I'd steer clear of Amcor, they have significant problems.

As someone else said, stick with the low power ones for domestic
use as theyre quiet.
