Or you can add a condensate pump for about $40.

I got one for $.99 + free shipping.

Ebay ...doh !!!

Where was the heat in the first place?

Latent versus sensible heat.

You are ignorant of thermodynamics and unable to understand the physical
principles.
 
So you're saying a dehumidifier that consumes 800 watts of energy is
providing more than 800 watts of heat?

Yes. If it's like the one I measured, it would provide 1.6x800 = 1280 watts.
BULLSHIT!!!!

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.

Don't waste your money on one. I had an 8000 BTU model. It was a
worthless piece of junk. They have a *very* serious design flaw - the
air the gets blown across the condensing coils (high side, the hot part)
on normal a/c units comes from outside, blows across the high side, and
is vented to the outside. Works great. With the portable units, the air
that blows across the condensing coils comes from the room your are
trying to cool, and is vented to the outside. This causes a relatively
high volume of air to be vented to the outside - and hot air to be
sucked into the room. IOW, it is constantly sucking in a lot of hot air
from outside, and trying to cool it along with the hot air that is
already in the room. Because of this, they will not cool as much space
as a window mount 8000 BTU unit will.

Bite the bullet and get a window mount unit.

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.

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..

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.

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!

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.

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 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.

I think NYC water is about .00001 c per gallon.

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.


Oh well... .

Thanks everyone, especially to those who pointed out that some have 2 hoses.
I was wondering before if the single hoses were split.

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.

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 :)
... the unit is NOT creating more heat then it's using, PERIOD!

Wow, you really ARE stupid... and not embarrassed at all? :)

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

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