Since the SF on the 1HP Sta Rite was 1.25 would you have any idea how much I might save with the new WhisperFlow running 8 h per day.
Cost of electricity is $0.20/kwh
Depends on your plumbing and which pump you got (WF vs WFE) but as a rough estimate, your old pump probably used around 1400 watts while your new pump uses around 1300 watts. So you are probably saving 100 watts per hour of operation or $0.02/hour.

BTW I gravity feed the back wash water back into the pool after it settles and clears. Essentially I use only a gal to back wash my pool
Sounds more or less like a homemade separation tank.
