Energy Efficient Pool Pump

[mas985]

1) It is some arbitrary but most POs with two speeds find they need at least 1 hour per day at high speed for better skimming and a cleaner. Low speed usually doesn't work so well for both of those things including myself. I can't create a scenario that fits all pools so I make the workbook available for those who want to customize it: Pool SpreadSheets

2) Larger motor (>HP) generally have better efficiency only because they use larger wire to handle the current. Also, the motor type makes a difference. Anything with a run capacity such as a Permanent Split Capacitor (PSC) or a Capacity Start Capacitor Run (CSCR) motors are more efficient than the motors with just a start capacitor. But for the Whisperflo, the main difference is HP.

3) Depends on the TriStar. The standard two speed pumps have CSCR motors which have better efficiency. The TriStar VS is an ECM permanent magnet motor. BTW, what sort of problems are they having? I know Hayward has had some issues with bad seals over the years which a third party manufactures so unfortunately they get the bad rap for it.

I don't know. I got the reports second-hand from the assistant manager of the local wholesaler. Like I said, I don't know how indicative those reports are -- and in my experience, every pump comes off second-best compared to the SuperPump's reliability which has dominated this local market. But, I'll try to remember to ask him for details the next time I see him . . . when he has time to talk.

Thank you both! I think I have been running the pump much longer than needed based on information given by the installer. It sounds like Ben's recommendation is a smart one (2 speed). Thanks again and I will keep you posted on the results.
