How do you know if your water heater is full?
Ok - so I have read never turn on the 110 heater coil in your water heater unless it has water in it - how do you know if its full or not?

Just to re-enforce what malexander said: make sure your heater bypass valve(s) are closed.
If the valve(s) are open, water will come out the hot water faucets and the electric heater element will burn up in seconds.
