I have personally installed some of these pumps in southern California and they are excellent. Every install saves $55 - $105 a month. We program for 22 hours at 20gpm and 2 hours at about 60gpm. The slow speed makes the water crystal clear. When you vacuum or run spa jets it can do up to 125gpm. That is about 2 horsepower. Your pool service company should be able to give you an exact electrical savings for your situation. Pump is almost silent. You have to stand next to it and listen carefully when it is in the 22 hour slow speed. Awesome!
