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?

Close all faucets/water outlets. If there is air in any lines, the water pump will run for a short time, intermittently. Either slowly open the relief valve on the water heater till water flows or do as others have said and let the faucets flow until no bubbles.
