If I did the Lowes 2.5 gal expansion tank with an efficient high flow pump the pump should run a few seconds then be off a minute then on a few seconds again. I have to imagine this would use much less electricity. Anyone experiment with pumps to see which is the most energy efficient?
Pumps are made to run, not start. Starting a pump causes a high inrush current that can be higher than the total when it is running a few minutes. Also, the hardest thing on a pump and its quickest killer, is a short start/stop cycle, ie: running doesnt kill a pump, starting does.
