    Get one with two hoses, the single hose ones cause a fair bit of
    outside air to infiltrate in

    Ahh I see I have a fan:) thats awesome makes for great debates that
    invaribly I win.

    Locally a portable unit is 450 bucks

    thats kinda pricey

    You can buy 3 5000 BTU windows units and have bucks left over.

    plus no messing with condensate drain, noise mostly outside, walk from
    room to room in comfort.

    plus often its useful to cool say a bedroom before bedtime.

    with a portable it will already be in use.

    so please explain why my advice is bad. sure portables have their
    place but its not a mainstream product, since its cost is high
     
  3. Wish I had known about the two hose units! :(
    Now that I think back, I seem to recall two hose units, but didn't realize
    the purpose.
    Unfortunately, never saw any two-hose units when I was ready to buy, and
    likely the PC Richards people wouldna known what they were for, either.

    Good link, but website wasn't that informative--no price, EER. Any ideas?
    Other observations good as well. Prodigious condensate. I "prefer" to empty
    buckets/use the water, but it is a chore.
    A pump to a storage barrel would be better.
    The 850 watt Amana can readily fill a 5 gal pail in 24 hrs.

    They're all pretty much the same, there's virtually no difference at all
    between the small rotary compressors they use, and they're all about the
    same efficiency (not very) due to mandated standards. Buy one that has the
    features and cosmetic design you like.

    The OP said he didn't require heating. I think you're a bit on the
    high side in your heat output estimate. I think 400 watts for a
    residential unit would be more realistic. You're dropping the
    relative humidity which will affect latent heat, and the units
    themselves only draw 600-800 watts. Even a heating element isn't 100%
    efficient.

    R


    Dehumidifiers don't use heating elements, they just pass the chilled
    dehumidified air through the condenser which heats it back up. There's some
    net gain, since the power consumed by the compressor (about 400W) becomes
    heat.
     
  8. What would be realistic is :

    The total power consumption of the unit
    plus
    The latent heat of condensation of any water it takes out.

    100 % of the above will be sensible heat in the space.

    Not another one...

    Since when is electric heat not 100% efficient?

    What are you using the water for?
     
  12. Or you can add a condensate pump for about $40.
     
  13. So you're saying a dehumidifier that consumes 800 watts of energy is
    Yep. Think of it as a swamp cooler in reverse. An unswamp heater.

    Psychrometrics are not so favorable, however. It's a dry heat.
     
  14. I prefer to haul it out in 5 gal buckets--water ther tomatoes and whatnot.

  17. From elsewhere, I know he's also a machinist--and so probly he uses it ( as
    do I ) to mix with water soluble cutting oil or synthetic instead of buying
    DI water...just need to add an anti-microbial..

    Well, it will produce more than 800 watts worth of
    heat. Where did the extra come from, the
    condensing of the water from the air. When water
    vapor is condensed to liquid, it gives up heat.

    Where was the heat in the first place?

    In the room... so it's not EXTRA heat!
     
  20. Fucking idiot, as usual.

    Don't dispose of the water, and don't take in any additional moisture and
    then what exactly do we have here now?
