I have been reading about the potential energy savings of a variable speed pump. My electric utility offers a $200 rebate, so that would help offset the cost.
My question is in how much that energy savings would be offset by the VSP being a larger pump? My current pump is a Pentair WhisperFlo WF-23, 3/4 horsepower pump, with a service factor of 1.27.
The Pentair IntelliFlo Variable Speed is a 3 HP pump. Will the much larger motor offset any savings I would have gotten? Pentair doesn't seem to have a variable speed 3/4 or 1 HP pump.
