The variable-speed pump has been the #1 leading technology "game-changer" for residential and commercial pool owner's for the last 10 years. The pump technology has dramatically (like, really really dramatically) reduced the power consumption for every pool that has a variable-speed pump installed. The combined energy savings worldwide since the introduction of these pumps into the pool market is astronomical!
The key to any energy savings with these pumps is PROGRAMMING. It doesn't make much sense to peg these pumps at maximum 100% capacity, 3 Horsepower or 3450 RPM 24/7! Smart, efficient programming based on your pool's water flow needs will determine the amount of energy you will save. Expect energy savings in comparison to your older, single-speed pump anywhere from 40% to 80% (if the pump is programmed correctly).
Love Pool Care has installed, programmed, and repaired thousands of variable-speed pumps in the Phoenix market... "Ground Zero" for pool equipment applications! Without a doubt, the Pentair Intelliflo (all generations) has maintained the lead in pump quality, efficiency, dependability, and overall ease of use.
The Pentair IntelliFlo VSF (Variable Speed & Flow) 011056 is our pump of choice, and will continue to be until another manufacturer proves to us otherwise. Why do we like this pump so much?
