I'm trying to decide whether or not to upgrade our current single speed pump, which works fine, to a 2speed or variable speed. I've had some people tell me it would be cheaper to just stick with my current pump until it fails but I'm a numbers guy so was hoping someone could help me work the math. I've been trying to find info on this but I haven't been able to find any info that didn't seem biased. What i need to know is the average kwh that a 1 hp single speed pump would draw per hour, the kwh that a 2 speed would draw on a low setting, and how many times a day a pool should be turned over. Thanks friends and have a great day.
