???? How is that possible? Where did the heat go?

I had this problem a year ago, and that's how I found the problem: My
water was suddenly ferociously hot when I'd shower. The short feeds
through what would be the neutral side (bypassing the thermostat).

I'd get just a little bit of discharge when I opened the T&P valve
manually, so I guess it was just on the verge of overpressure or overheat.

You could hear the localized boiling just by standing next to the water

What limited it to
30 amps?

I was wondering the same thing. It's not a dead short, but very very
low resistance.
