12.5 cents per day
Yep, with my new settings on the VFD pool pump we're down to 12.5 cents per day.
1000 RPM for 16.5 hours @ 54 Watts = .891 kWh
2400 RPM for 2.5 hours @ 350 Watts = .875 kwh
1.766 kWh @ $0.071/kwh = $0.125 per day
Taking into account rounding, I'm down to $46 per year for the stupid pool pump. Before, I was running a 1hp pump 14 hours a day
1 hp with a 1.86 SF = 1379.5 Watts
@ 14 hours per day = 19.3 kwh/day = $1.37/day or $500 per year
Now if only I could do something about the pool cleaner boost pump, which uses 1035 Watts for 2 hours a day...
