It has a grounding cord, but the ground is totally redundant because the tank is tied into the copper plumbing. (That would not be the case with non-metallic plumbing.) I made a choke with a two-wire extension cord, and left the green wire open. No more cold showers.

That's NOT an exception, because 1) is a VERY unsafe, and 2) it is a 
major violation of virtually all building codes in North America, which 
require that the Green Wire run WITH the phase and neutral conductors.

Because you have added resistance and inductance to the grounding path, 
you greatly reduce the likelihood that a breaker or fuse will operate in 
the case of a fault.
