I'm hoping to rip this tank out in a couple of weeks. Any free time/money before that happens will be prepping for the replacement and the solar setup. One of my future plans for the "it runs everything" arduino project is have it switch a relay to turn the tank off the easiest way to do that may be to hack a digital timer. I'll look into it later. For right now I'm curious how this bit of insulation makes a difference. I think somewhere in the back shed I have enough to finish wrapping the tank and I'll do that tomorrow if I dig it up.
