I have a 20X40 pool with a spill over SPA. Currently I have a Hayward Super pump II model SP2510 X15 (1.5HP Single Speed). The motor is bad and needs to be replaced so I am not sure what to get.
1. I had considered switching to a two speed motor to save energy. With my Jandy system I was thinking I could run it at low speed for pool circulation and then bump it up when using the spa. Would I save that much energy vs the cost of a two speed motor ?
2. Just get the same motor.
3. Buy a new motor and pump. ECM or two speed.
Since I need to replace the motor anyway I was hoping to replace it with something that would reduce my electrical bill.
