I am leaning towards replacing our current pump, which is a Whisperflo single speed 2.5HP model (see pic), with a variable speed intelliflo 3HP model, such as the one below:
Amazon.com : Pentair 011018 IntelliFlo Variable Speed High Performance Pool Pump, 3 Horsepower, 230 Volt, 1 Phase - Energy Star Certified : Swimming Pool Water Pumps : Patio, Lawn Garden
Using back of the envelope calcs, I figure my energy savings would be roughly $20/month (depending on how it's ultimately setup of course), but would provide other benefits such as being quieter, having freeze protection, and being able to run the pump longer at a lower speeds in order to keep the water moving. So it's not all about immediate financial payback as I know that will take some time given the purchase price.
Would there be any issue replacing my current model (2.5HP) with this one (3HP)? My old model is 230V so I think in terms of electrical it's no problem (assuming I don't electrocute myself). Also, the pump today is hooked up to the intermatic timers so could I bypass those with the new pump?
Thanks for everyone's help.
