I have a motor that has died on me; i've replaced the capacitor and it still won't work. it's about 8-10 years old so i think it's finally time to replace it. The impeller spins freely but just won't kick into high gear. I have a 38,000 gallon pool in South Carolina with a Jacuzzi salt system installed last year. I would like to save some money on operating costs. I currently run the motor about 10-12hours/day in the peak season, and 4-6hours/day in the winter. i do not cover the pool in winter. there is also a booster pump that i run 2 hours/day for the Polaris.
I guess my two main questions: given the above description of my pool, how much money would i expect to save using a variable speed motor? how do i determine what speed and hours/day to run the motor to get the most efficient?
I have a US Motors 1.5HP 1.3SF 3450RPM 56J. I think it's a Hayward Super Pump (square top not round).
I can't seem to find the direct replacement for a single speed motor with the same specs. I found the dual speed AO Smith 1.5HP B2977.
But I am reading about the more efficient variable speed motors, like the AO Smith 2.7HP ECM27CU
