I have begun looking at replacing my Superpump with something which could give me electricity savings. I saw that my 1.5 hp superpump flow rate curves match almost exactly with a full rated .5 hp whisperflo. I then went to the maximum electricity used in each. The Superpump says its 1.5 hp draws a maximum of 1.1 Kw. The Whisperflo .5 hp energy efficient model draws a maximum of 5.6 amps at 220 volts. I was told that this converts to 1.2 kilowatts (5.6 times 220 volts), which is more than the 1.5 hp superpump. I have no idea if this is correct as my understanding of the relationship between watts and amps is limited, at best. The Pentair website also indicates that the standard motor draws slightly less in amperage than the energy efficient motor (5.5 amps v. 5.6 amps). Can anyone help?
I am also looking at two speed pumps. I am not sure if they would play well with my with my solar heater unless I got a controller that could turn them on high every time the actuator turned on my solar, but that is a different issue. The low speeds seem to max out at just over 20 feet of head and my panels are on the second floor roof, about 20 feet up.
