  1. I got one for $.99 + free shipping.

    Ebay ...doh !!!

  2. Where was the heat in the first place?

    Latent versus sensible heat.

    You are ignorant of thermodynamics and unable to understand the physical
    principles.

    Yes. If it's like the one I measured, it would provide 1.6x800 = 1280 watts.
    Do you believe a 500 watt air conditioner can move 1500 watts of heat? :)

    It's time to admit you are wrong and apologize for your arrogance.

    or get one with two hoses, that draws in its condenser air from the
    outside

    I've had a Sunpentown 13000 BTU unit for 3 years. It's
    very effective, efficient, and the condensate goes out
    with the air exhaust. I installed a dryer vent through
    the wall to regain the full use of my window. It keeps
    the computer room cool and doesn't cost a lot to run.

    Ordering over the Internet, including shipping, was
    comparable in price to buying a 9000 btu unit with a much
    lower efficiency rating locally.

    The quality of this unit really surprised me.
     
  6. I'm flattered... you didn't insert the adjective "wannabee".
    Ahma haveta tell the group.... :)

    Indeed, soluble oil, but the output is too prodigious even for that (on a
    maintenance basis), so I basically pour it around the plants/lawn/house.

    I tried draining it right into the Fadal resevoir tank, figgered it'd be
    good as "makeup water", and boy was I surprised to see the tank overflow
    (30-35 gal!), not to mention the coolant getting awfully thin in the
    meantime.

    So I had to stop that, and do the 5 gal bucket thing.
    Somewhat the pita.
    Each 5 gal bucket is 40 lbs, made more difficult by pulling it from an
    awkward location, and then tryna not spill it, and then for some distance.
    sheeesh.....
    I think NYC water is about .00001 c per gallon.

    Oh well... .
    But, you know what they say:
    00001 penny saved is .00001 penny earned.

    I understand shit that you don't.

    The heat was there to begin with idiot!

    With an air conditioner the condenser is OUTSIDE.

    With a portable dehumidifier, the condenser is INSIDE.

    Big difference and the unit is NOT creating more heat then it's using,
    PERIOD!

    They are all pretty ineffecient. Better effeciency can be had by
    spending more money on central A/C (higher SEER) or a mini-split (for
    example Fujitsu's run up to a whopping 21 SEER). In both of those
    cases you would need a professional install.

    That being said, a dinky little A/C like that, even running at 8 SEER
    or something crappy like that, is not going to break the bank just
    because it's not big anyhow, and you probably don't run it 24/7.
    Additionally, depending on your situation, wasting some electricity
    dollars may be ok if the alternatives (putting central A/C in your
    rental unit or something) don't make sense. This "ineffeciency" may
    add up to something like $10 a month (guessing here) so it may not
    matter.

  10. Last year's rate was $2.02 per hundred cubic feet (ccf)
    PLUS an additional 159 percent for the accompanying
    sewage dump [a], or $5.2318 per ccf.

    With 750 gallons per ccf, that's $0.0069, or
    about 0.7 cents (3/4 of a cent) per gallon.

    Note that this is _last year's_ rate. There's
    been an 11 percent increase propsed
    for this year. I'm pretty sure that's the
    final number, but there might be some
    slight adjustments in the pipeline.

    [a] for most customers the pipeline water
    is the same quantity as the sewage dump. The
    city will do separate metering if
    there's a major difference - for example,
    if you're using well water for your
    car wash and dumping it in the sewer.


     
  11. Thanks everyone, especially to those who pointed out that some have 2 hoses.
    I was wondering before if the single hoses were split.
     
  12. I once read about a guy who used water (from the main supply) to fill a
    bucket that pulled his heavy iron driveway gate open, and *then* went to
    watering the plants.
     
  13. No doubt a guy with much too much free time.... :)

  14. I understand s*** that you don't.

    No doubt about that. Just not thermodynamics.
     
  15. Big difference and the unit is NOT creating more heat then it's using,
    Define "create".

    It doesn't "create" heat in the sense of violating energy conservation.

    However it does convert latent heat that doesn't affect a thermometer to
    sensible heat that does.

    Just think of it as evaporative cooling in reverse. Condensive heating, if
    you like. Multiple joules of sensible heat appear compared to the joules
    of energy used to run the machinery.

    By the way, that's 800 watts of power, vs energy.
    You might enjoy learning the difference :)
    Wow, you really ARE stupid... and not embarrassed at all? :)

    Think really hard. It takes energy to evaporate water...

    Whatever, you can believe what you want... even if it's wrong!

    It "converts" heat, but it doesn't "create" it, it was in the space already!
    Therefore, it's not 100% + efficient.
