   Hate to burst your bubble, but water conducts electricity. If one of those   
   heating elements ceases to become watertight inside the tankless unit, you   
   will have electricity going straight through the water and seeking a source   
   of ground. Quite frankly this potentially could be happening now and I   
   would've suggested it as the cause of the tripping breaker if only one   
   breaker was tripping. Both heating elements would have to be compromised in   
   order for both breakers to be tripping. The chances of it randomly happening   
   to both at the same time are very remote.
