Any mishap wih a heater or any electrical equitment can be avoided with a GROUNDING PROBE! 15-30$ at ur lfs or online, i got a titanium one a few months back after my circulator was leaking ac current. All it does is ground the tank!
A very smart buy imo!

Grounding probe will reduce voltage, not current
Current kills, voltage is the potential of the current
