Hello to all. I am considering a 1 speed or 2 speed whisperflo (1.5 HP uprated) and I am torn with regard to which one would work out best in my situation. The pool….if it is ever finished will be 34K gallons with no spa or waterfall. The cost of electricity in our area is not high but I will take all the savings I can get. The main reason that I am considering the 2 speed is for the winter months. We are hoping to be able to leave the pool open in the winter. We have an Autopilot that has a freeze guard, but I was wondering if it would be better to simply run the pump 24/7 on low speed during the winter months and not worry about the temps outside or the equipment cycling on and off. I am in OKC and the temps can get pretty cold. We have been in the low 20’s several nights this week and would guess the water temps would be in the 40’s. PB doesn’t see much benefit in a 2 speed pump and says low speed is practically useless. The cost difference is about $150 for the 2 speed. Also, PB has offered to upgrade the Pentair SD80 filter to the Pentair TA100 for $200. Is the larger filter worth the cost? The Pentair rep says the SD80 is the filter recommended for the pumps we are considering. Any thoughts would be appreciated?
