Getting tired of the cost of running my 1 HP Hayward Super Pump, so I've begun researching dual or variable speed pumps. Our pool is 18x36 and I've estimated ~20,000 gallons. 1 1/2" piping. We do not have 240V wiring at the pump, so would really prefer to keep any replacement to the 120V to avoid extra electrician expense. I also can get a $300 rebate from energy company on a variable speed pump (need to double check if it's still good if self-installed, which is my preference. Let's assume it is). I've done some testing using a kill-a-watt and looks like my current pump averages right around 1 kW per hour, which from what I've read seems inline with my pump size. In reading old threads, seems that it's difficult to get the payback on a variable vs just getting a dual speed. That said, maybe the $300 rebate tips the math in my favor? Also - my desire to stick to 120V also seems to restrict my choices. Best option I've found thus far is the Pentair SuperMax VS Variable Speed Pump 115/230V - 343001. Presently $820 but would be net $520 for me post rebate.
Looking for some advice/experience of those that have gone through this process. Pump is at least 6 years old (was in place when bought house), but put a new motor on in 2017.
