The water heater that feeds a clothes washer and a kitchen sink went out and I'm going to replace it with a tankless.
I have both a dedicated 120v line with a 30amp breaker to use or I can have the electrician tap into the 220v line that powers the living room airhandler.
My question is this: The current breaker on the 220v line is 30amps. The 220v tankless needs up to a 60 amp breaker. If an electrician taps into that 220v wire and adds the 220v tankless on it, can he then just upgrade the total amps on the breakers to 90amps to ensure that both can run at the same time without tripping the breaker?
