You've been reading my TODO list! One of my spring projects is to trip the well pump early and pump up the pressurized accumulator tank early when I have surplus power. Ordinarily I let it cycle through a wide range since a gallon stored at low pressure takes me much less energy than a gallon stored against high pressure. More than linearly since it is a centrifugal pump and between the head and the lift I'm pushing the limits. I can't do hot water. I use an on-demand propane unit that can't throttle down enough to accept preheated water. Once that wears out I'll replace it with a unit that can accept preheated water. Two olympic sized pools would be a little decadent plus, I've only got about 12 feet of altitude variation to work with. Constraint of a small island, on the other hand, I do have over 1000 cubic miles of water in the lower pool.
