Designing a new IG residential pool. I am digging through posts on this topic but I wanted to post my own pool specs (still in the design phase).

Is it worth paying an extra $750 to upgrade from a Whisperflo pump to the IntelliFlow 4x160?

My main factors are energy savings if I can take advantage of some of the lower settings on the Intelliflow but still keep the pool clean. I will have a separate blower for the spa. I will also have a legend pool cleaner with its own 3/4hp pump.

85' perimiter IG pool
420 sq foot of pool surface
Approx 13225 gallons
16' perimeter attached spa
51 sq foot of spa surface
2 skimmers with separate runs to pump
4 surface returns
Pentair 420SF Cartridge Filter

Thanks for you input.
