Hello,
My 3/4 HP Hayward Northstar circulation pump motor is dead. I've decided on VS to replace instead of dual speed since my marginal electric rate is $.32+ kWh most months. I've spent a good deal of time using mas985 spreadsheets to evaluate pumps and narrowed to three above in addition to the V-Green VS replacement motor. First question: Does the V-Green retrofit to a Northstar wet housing? If so, is it possible to compare efficiency of the resulting configuration to the other pumps? Could this configuration be categorically dismissed because the Northstar is an old design in comparsion to the new pump/motors designed work together? Next question: Considering my application below, do any of the mentioned pumps rise above the others? Here are the stats:
- 19,000 gal IG plaster w/connected spa overflowing to pool
- separate jet pump for spa
- separate pump for roof mounted solar
- Hayward Navigator suction side pool cleaner
- all 2" plumbing at equipment pad
- 325 sf cartridge filter
- 35' equip pad to pool, 45' equip pad to spa
- 220V wiring
- Jandy RS4 controller
Any advice would be much appreciated. Thanks!
