Pentair intelliflo variable speed pool pump 011018 electricity projects for high school students

#############

BEST ANSWER: I am on my third season of using this pump. I had a constant speed pump before. The VFD pump requires a bit more work because I do not have a pool control system that can automatically electricity kwh to unit converter speed up the pump when my gas fired pool heater is used. We manually push a button on the pump to put the pump in a pre-configured higher RPM speed to provide enough water flow across my heater when the heater is in use. My pool is 31,864 gallons and I run the pump 14 hours per day at 1,200 RPM (uses 196 watt per hour) to get one turnover of pool water in my FNS DE 60 sq. ft. filter. My old pump used over 2,200 watts per hour and I ran it for eight hours a day. The k electric jobs test VFD pump is a real money saver ($3 per day or $540 per season @ $.20 per kWh). You cannot hear it running at that low speed unless you are next to it. The programming is easy and the VFD Pentair pump has the same footprint and piping port locations as my old pump. Check the amperage of your two speed pump on low speed (and convert to watts=volts times amps) and compare it to my figures above and see if it pays to switch just due to energy savings. I do not believe it will be. My pump had a bad bearing so it was a no brainer to spend the extra money (constant speed gas tax in texas pump cost verses VFD pump cost) and also get less than a two year payback. In addition the pressure reduction going thru my DE filter from the old pump was dramatic (from 20 PSI to 4 PSI electricity in the body symptoms). This will make my DE filter media last forever. Replacing the DE complete cartridge is over $1,800. Also by running the pump for longer hours the pool water stays cleaner because the skimmers are removing any leaves or pollen that use to drop into the pool and sink when the pump was not running those additional six hours.
