Thanks for the helpful information on the forum on helping me decide which pump to get. I went ahead and ordered a new Pentair Intelliflo VS to replace my 2006 2HP single speed pump. At $0.0743 per kwh for the first 1 - 2,000 Kilowatt hours and $0.0979 for 2001 - 4000 Kilowatt hours it may take awhile to recoup the cost of the pump. But after a $200 rebate and selling my old pump I will only be out $600 or so for the pump not including the install and 3 new valves. I look forward to be able to swim and not hear the pump running in the background.
