Your analogy falls apart in that an electric water heater is more like a thermos than a teapot.
Well somewhere in between, but closer to the teapot. The thermos does not have copper pipes sticking out thru the vacuum jacket.

If you have the parts for free to turn the heater off sitting in your junk boxes, it makes sense to do so. If you have to buy them, then do a payback calculation.
