Here in San Diego our utility is switching us over to a Time Of Use (TOU) plan. Using electricity (and I suppose natural gas) after 9pm and before 6am is the the cheapest time, so I'm wondering if there are any downsides to running my pump mostly at night and before 6am. I will still run it between 10am and 2pm (also cheapest) for my solar, which needs higher speeds to pump the water up onto the roof (which also runs my cleaner faster too), although I don't need to run it at all during the day (for solar) during the winter months.
Thoughts?
