I'm renovating a small house and want to install an electric tankless water heater to save space. A local store offers one that requires 2 50-amp breakers; the house has 200-amp service. The house also has:
- an oven (40 amp breaker)
- maybe a stackable washer/dryer unit (30 amp)
- heat pump (2 ton - not yet installed, I'm guessing needs 25 amp breaker)
Will the 200-amp service be enough to handle all this?
