How does an electric water heater work?
Most electric water heaters are tank-type models that share the same basic anatomy. Electric heating elements inside the tank serve as the heat source for the stored water. A thermostat controls the current to the heating elements to maintain a water temperature between 120 and 140 degrees. Hot water leaves the tank through a pipe at the top of the tank. Cold water enters the tank through another pipe.
A sacrificial anode is installed inside the tank to help minimize corrosion on other parts of the system. A relief valve in the tank wall is designed to open if internal pressure or temperature exceeds safe levels. A drain valve at the bottom of the tank allows accumulated sediment to be drained periodically. All new tank-type water heaters have insulation covering the tank to reduce heat loss and improve energy efficiency.
What can go wrong with an electric water heater?
On average, an electric, tank-type water heater will last 10-15 years. Basic maintenance and (in some cases) occasional repairs will help prolong the heater’s life and improve its performance, too.
- Sediment. Corrosion inside the tank, combined with mineral deposits, eventually creates a layer of sediment at the bottom of the tank. This buildup should be drained at least once a year.
- Leaks. Water can begin to leak around openings for valves or pipes, or through worn valves. Metal tanks can corrode from the inside, developing leaks through weakened wall areas.
- Faulty thermostat. If the thermostat isn’t functionally properly, the stored water can get too hot, or stay too cool.
- Broken dip tube. Present on some tank-type water heaters, the dip tube can break or detach, cooling off the hot water supply before it leaves the tank.
- Corroded sacrificial anode. An older, fully corroded anode should be replaced with a new anode to maintain corrosion protection.
- Broken heating element. Electric heating elements can be damaged by lime buildup or sediment deposits.
Malfunctioning relief valve. The relief valve can cause problems if it leaks or if it doesn’t open at the correct temperature and pressure settings.
