I was redirected to this forum by someone in the pumps tanks forum. I need to pump water from the deep end(approx 6 ft) of a swimming pool, up a pillar to the ceiling, across the ceiling and up to the 2nd floor to an HVAC unit that uses water to cool the freon in a coil. After the coil, it exits thru pipe and simply spills back to surface of pool to dissipate heat. Can anyone thell me what kind of pump I should use, I also want to use an energy efficient pump. The current configuration uses the 1.5 hp pool pump and it has to run 24/7 using too much power.!
