Just opening the hot water valves will definitely not insure that the water tank is full.
If the wh bypass accidentally gets turned or is stuck you'll still get water from the hot water taps.
You need to fill the tank and purge the air from the pressure relief valve on the water heater.
Never heard of a hum coming from a hw tank.
When using electric side you should actually hear a sizzle.
Btw did the dealer tell you that you can use them both @ the same time for faster recovery during shower times? Gas and electric?
