When shopping for a model, look for one with a built-in sensor that detects voltage/current 'leakage', which translates to a potential that the user might be electrocuted. On the two water heaters that we use, these are called ELB (Earth Leakage Breaker) on the Panasonic and ELSD (Electricity Leakage Sensing Device) on the AEG.

With these protection devices, you'll be safe if the heater core or its electronics develops a problem and starts leaking electricity into the water or anywhere electricity shouldn't exist. As soon as the safety mechanism above detects this electricity leak, it shuts off an internal breaker.

Equally important is to properly connect the heater ground wire (the green wire) to earth ground or alternatively, to a metal pipe that has several meters of its length buried underground. This is one of those things that your life depends on.
question po, pag wala ELSD yong heater unit, would a circuit breaker address this issue?? am considering some brands na wala ELSD, just want to confirm kung totoo yong sinasabi ng sales agent. thanks
