The cooling water is warmer? Therein lies the key to you efficiency. I
bet you don't count the amps the circulation pump uses? Some of those
things use up to five amps.


Nice try, but my pump is the common March 809, which draws 1.5 Amps.
(It might even be the half power version, but I can't tell without
un-mounting it.)

Even so, my Amp measurements include the pump as I have an Amp-hour
meter (half of my Link 2000) on the entire refrigeration system.
