1 Answer from this member: Unless you are very experienced on replacing water heater elements, Yes, I strongly recommend draining the tank first. Otherwise, it could cause a lot of damage. To drain the tank, be sure to turn the breaker and supply water valve off and open any hot water tap in the house.
Water is drawn off the top of tank, so you should you run out of water, your hot water heater remains full. To drain or empty the tank you must remove the drain plug on the bottom. What burns out is the heating element or the burner tube depending you your choice of fuels. Bill.
