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

[Gene Helfman]

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,
