[C320-list] Basic hot water heater and charging question

[Jeff Smith]

Gene,

I may be wrong, but my understanding is that the water heater draws AC current when on shore power. When motoring, hot water occurs because of the recirculating system ‎using the cooling system of the engine. Thus, you will have residual hot water after motoring until the heat finally dissipates.

If I recall correctly, my hot water breaker is a push button breaker, not a toggle.

Hope this helps. Someone should correct me if I am wrong.

Very basic: from where does the hot water heater draw electricity?  Is it
off the battery bank?  The alternator? The battery when the alternator
isn't charging?

 I ask because we are having alternator problems when motoring.  Or maybe
voltage regulator problems.  We get full charging for 30-35 minutes
regardless of battery state, then it shuts off, meaning we are then drawing
from the house 4Ds. When we shut the engine off (an hour or more later), we
have lots of hot water. We're concerned that once the alternator shuts off,
the water heater is still drawing power until the WH thermostat shuts it
down.

If so, is there an easy way to turn the hot water heater off.  It isn't an
obvious toggle on the instrument panel.

thanks,
