Reheating Tank

[sphelps]

It'll take a while for the tank to heat up anyway so I wouldn't be concerned about heating it up too fast.

See if you can setup your controller with black out delays at different intervals for various equipment, that way everything won't attempt to turn on at once and trip breakers/GFCIs. I personally don't run my return pump and controller power through a GFCI, everything else yes but the controller doesn't need it and the return pump is just too important.

Best of luck.
