These motors are now code for pools in my city. I had pool built right before they became code and it wasn't even mentioned as an option. My builder is the "finest" in the area, but missed this opportunity to give me an efficient pool. I would have liked to have the lower run-cost option. The filter efficiency is still good because they don't "jam" particulates through the filter media with excess flow. I have a friend that switched his to 2 speed motors. He figured it would pay for itself in a year or two.

This isn't enough info to do a calculation but an encouragement to keep up the research. There are 2 speed motors and variable speed. I presume you can dial in the lower speed with the variable type - but the controllers increase cost quite a bit. There is also the need to have a control module in the electronic control unit. Or perhaps the two timers can be wired to control it, but if your sophistication installs a variable speed pump, then a programmable timer seems appropriate.
