Does anyone have one themselves. Are the savings between variable speed and single speed really that great? And would you say the high upfront cost offsets itself with the savings?
I have a Pentair 3HP VS Pump. Its super quiet, and like Jim, I run mine 24/7 and costs about 20 a month. If it died tonight, I would buy another one just like it immediately.
I recently replaced a single-speed 1.5 HP 3450 RPM pump with a Pentair SuperFlo VS. The old pump pulled over 2000 watts and everything was always at hovering at the skimmer: floating lights, kickboards, floats, toys etc. I have the SuperFlo programmed to run at 1,200 RPM for daily circulation. At that speed it's nearly silent and uses 170 watts. The skimmer isn't very effective at that speed however, so when necessary I run it at 2,800 RPM which pulls 1,080 watts. The surface stays clean, but I can have items float in the pool without immediately heading for the skimmer.
I have an app that monitors energy consumption in my house in real-time. The difference is impressive. No regrets.
