Hi Carl,
Ok your running at 1/4hp, on a pool pump with plumbing and filtration load I would guestimate that is using 280 watts per hour x 12 hours = 3.36kw per day
I don't know your flow rate but again a guess at that level 38 GPM.

My system is built to be super efficient and I know if your flow rate less than 22 GPM then the skimming action on the surface is not good enough with a skimmer but it could still work with an infinity edge.
My pool runs at 23GPM overnight (16 hours) and when swimmer are in the pool 26 GPM (8 hours) but the total electricity per day is just 960 watts 0.96kw.

The reason for 24 hour running is that I have many trees and also we are in a farming area so debris is usual, if the pump isn't running this debris gets water logged and sinks, some people spend $100's on pool robots, if they spent that upgrading the system they wouldn't need the robot, I sold mine a few seasons ago. If the pump is running it gets skimmed off and the water stays cleaner.

I wish Marks report was more scientific, with proper turbidity test carried out and a particle count to see what was really in the water. If the pump is off the debris sinks but it doesn't show until it's stirred up. Since doing this the water is much clearer 0.5-1 NTU and there is no dirt or debris to stir up.

What Marks report does show is how little is really needed to keep the water in condition, too many people hung up on turnover rather than brilliant filtration which actually removes the dirt not just recirculates it.
Gage and Bidwell's paper on water turnover and dilution says after 1 turnover 63% of the water has been filtered, by my action I get a 6 hour turnover and that filters 4 times in 24 hours so 98% of the water is filtered. I am reducing the speed of my pump to just the 23 GPM for the full 24 hours as that will give just less than 3 turnover rates and 95% of the water filtered on 0.84kw of electricity and I will see if that makes any difference to the water quality. At that flow it should still be sufficient for a heat pump to run (just) but likewise a good solar setup may need a bit more push if it's not that well made but these are terrific energy savings.

There is very little leaf collecting or pool vacuuming to do compared to short running that I used to do.

John
