Yeah... now try designing something to run for
*10* hours on a battery smaller than your laptops!

Yes, it's a 220V unit.  I don't recall how many
tons.

And, it is possible I have forgotten how to "do
the math" when reading a watt-hour meter  :<
(like "Kelly" in MWC -- once your head gets full,
stuff falls out as you try to cram new stuff in!)
((or, at least it FEELS that way!!  :> ))

Our cooler flushes at least once or twice per day.
I think the "flush pump" runs open loop at something
like "flush after 6 hours".  So, if the cooler runs
100% during the daylight/dusk hours, that's at least
two flushes per day *plus* whatever water the cooler
pumped into the house (sorry, too many years since
I've had to do *that* sort of math... :< )

I need to reclaim the water -- along with the
condensate from the ACbrrr... --- but both are
in hard to plumb locations.  (I am not fond of
creating "eyesores" just to move the water from
A to B).  I am hoping to tackle this whenever
I can get around to building a cistern
(anyone have a section of 3-4' culvert they don't
want??  :> )

As I said, it is hard to know what the true water
use is by examining the water bill -- since we have
far too many water hungry plantings in the yard
and Summer really beats on their water needs  :<
(sure, having fresh oranges is "way cool" -- until
you realize what a PITA they are to maintain!!)
