Some people say that this pump will only run for a couple of dollars a day, other people dispute this, I like to hear from the Experts over here?
I am about to replace my pump which uses between 20-30 KW per day(24 hours on)
Update as of 10-1-2013
I did replace my old pump with an Eco-pump an EV4 and the electricity dropped by 400 % so it does work
Not only do I save on my electric bill from 55-60 KW per day average to 27-35 KW average right away, the pump is also running twice as long from 8 hours to 16 hours and halve the rpm 1750 versus 3500 RPM
Therefore in 3 weeks times hardly any chemicals used, the pool stays cleaner, more blue, less chemicals, less electricity.
more money in my pocket!
Overall the best money I ever spend on a pump period!, Ultra High efficiency, electric-bill cut in half, payback is 18-24 months on current level, 9-12 months, if dialed down to 8 hours a day !
Thumbs UP!!!

well if its a multi speed pump supposedly your using less kw per hour at low speed but u have2run the pump longer hours to get proper circulation,so thats a tough question…i personally dont care for them,the slow circulation leads to more algae and a dirtier pool overall…i know others will disagree
Yes, an energy efficient variable speed pump can save you thousands of dollars over the life of the pump.
The energy savings is a result of fewer watts being consumed to move the water at slower speeds. Because it is not a LINEAR equation, the watts drawn at 1750 RPM are less than 1/2 of the watts drawn at 3500 RPM.
But, the gallons per minute the pump moves are not linear either. You have to do some math to determine your particular runtime.
Most residential pools are designed for a 8 to 10 hour turn over. That means that in 8-10 hours the volume of the pool has passed through the filtration system 1 time. If you know the flowrate in GPM of your existing system/pump, this will be easy to traslate to the new pump.
You shoudl look at the pump curve of your existing pump. They are found on the manufacturer’s websites and in your owner’s manual. Compare that pump curve to the Variable Speed pump’s curve. They should be fairly equivalent.
Most homeowners realize the energy savings by utilizing the reduced speed, and just running their pump for a longer period of time (1/2 the speed usually equates to 2.5X longer run times). But since you are already running your pump 24 hours a day, it will take longer for you to realize the return on investment (ROI).
Variable Speed pumps are still more energy efficient that standard pumps - even when operated at full speed 24/7. Compare your pumps wattage consumption to that of the proposed energy efficient pump. Multiply the wattage saving by 24 (hours) X 30 (days billing cycle) X your KW cost per hour to determine your monthly savings.
Variable speed pump or Eco friendly pumps are bill reducing factor. The power savings is due to the fewer watts being consumed to move the water at slower speed. Variable Speed pumps are surely more energy efficient that standard pumps even if they are operated at full speed. Comparison of pumps power consumption to that of the proposed energy efficient pump will make you decide by yourselves.
Energy efficient pumps are a must if your concerns involve utility bills. They are great if you have water features etc that can be run on a lower speed also. Your climate will also play a role. The pump should be ran for 1 hr/ 10 degrees of air temp. Exmp: 75 degree outdoor temp= 7.5 hrs run time. Some pumps are oversized and they are variables but typically you want the pump to pull all of the water out of the pool, run it through the filter and back to the pool in a 6-8 hr time frame.
