The power bill difference running a single high speed pump for 12hours per day should be much much more than $25 if using a variable speed pump running at very low speed 24x7. Maybe that’s where the misunderstanding is?
Replacement pump with timer including freeze control OR using Intermatic timer version?

No I was comparing 1.5 vs to 3.0 variable speed the longevity is the issue 10 years no repairs versus 5 on smaller works otherwise smaller and replace every 5 years
I shut my pool down (ie blow out the lines) from mid/late December to early March just cause it freezes and I don’t want the hassle of worrying about it during that time.
The pump has been running non-stop since last March except for a couple shut downs to backwash during the summer.
The noise difference alone was the best benefit of running the pump at very low speed. I don’t even know it’s on unless you walk over there and check it. The secondary benefit is that the power bill doesn’t even noticably change when it’s running like that 24x7 but our homes AC does significantly increase our power bill though.
Ah, I see. If you only get 5 years out a pump that would not be cool. Im not sure smaller/larger is related to longevity and would guess it’s more about the manufacturers name. I’ve heard the really inexpensive seasonal type pumps can have issues like that though.
So the Inyo pump is definitely cheaper, does that make this selection a 5 year time frame? If so 3.0 versus 1.5 really not gaining anything. From talking to pool service techs around here they estimate VS pump 5 year life. These are intelli Flo etc. I felt lucky to get more than 4 out of the Waterway after talking to the pool techs
I don’t know anything about that pump, but from reading here a pump labeled Hayward, Pentair, Jandy can be expected to last much longer than 5 years. Anything else…not so much.

The point of the larger pump is you can run at lower speed and move the same amount of water at a lower cost, even if you don't run 24/7.
If you have to run the 1.5hp at 2500RPM to move 30GPM, in this example it would cost$81/mo.
If you can use the 3.0hp and run at 1400RPM and move the same water, it would only cos $18/mo.
Pump wear comes from turning them on and off. It is better for the pump to run 24/7.
Running 24/7 at low speed allows you to make chlorine all day and keep FC steady.

This stuck for me. I wish the intelliflo tech hadn’t jaded me to 5 year threshold and I doubt he was exaggerating. Most of the repair people work for pool companies that do not balance their pools the way that we do, so maybe their chemicals ruin pumps. I’m influenced to return the stuff to Inyo and go with a larger whisperflow since my fittings might work. Thanks again!
