I've been eying the Hayward eco star pool pump as a way to save on electric. It was mentioned elsewhere here the payback on these is pretty quick. They cost a bundle, $1100+, so I'm trying to see how it pencils out...
I put an ammeter on my existing conventional 3/4 hp pump and found it's drawing 5.4 amps, so:
5.4A x 240A = 1296W x 6 hrs/day x 30 days/month = 233.28 kWh/mo @ $0.11/kWh = $25.66 / month
That would be four years payback assuming the new pump uses zero. It isn't clear from the literature how much these new pumps actually draw. There is some suggestion it is in the 200-300 watt range, which would put the payback around five years.
Does anyone have one of these and can comment on what their actual current draw is? Also, do you run them more hours/day on slow speed? I'm also wondering what makes them more efficient. Sure people say they use less electricity because they are running slower, but presumably they are pumping less water in the process, so couldn't I accomplish the same thing by reducing the number of hours my existing pump runs?
Thanks in advance for any insights.
