Water Heater Element Replacement Cost

Most electric tank water heaters have two heating elements, upper and lower, each controlled by its own thermostat. When an element burns out, the water runs lukewarm or cold.

Cost

HomeGuide's average for electric water heater repairs overall is $100 to $350, lower than its $50 to $600 for gas.

Signs of a bad element or thermostat

• Hot water runs out much faster than before (often the lower element).
• Water is lukewarm or there is no hot water at all.
• The breaker for the water heater trips.

Before booking a repair, Angi notes that a tripped breaker costs nothing to reset. If it trips again, call a professional.

Element replacement and safety

Element replacement involves both electricity and draining the tank. Turn off the breaker before opening any access panel. If you are not sure the power is off, hire a plumber or electrician.

Repair or replace

An element is usually worth replacing even on an older tank. If the tank is leaking or over 10 years old with repeated problems, compare with electric water heater replacement cost. Angi lists electric tank replacement at $600 to $3,500.

How electric water heater elements work

Most electric tank heaters have two heating elements, one near the top and one near the bottom, each controlled by its own thermostat. When an element burns out, the heater produces lukewarm water, runs out quickly, or produces none at all.

Signs of a failed element

• Hot water runs out much faster than before.
• Water is warm but never hot.
• No hot water at all, especially if the breaker is fine.
• The breaker trips repeatedly, which can mean a shorted element.

What the repair involves

A technician turns off power at the breaker, tests the elements and thermostats with a meter, drains the tank enough to expose the element, unscrews the old element, installs a new one with a new gasket, refills the tank, and only then restores power. Turning power on before the tank is full will burn out a new element immediately.

What affects the price

Elements and thermostats are inexpensive parts, so most of the cost is the service call and labor. Replacing both elements and thermostats at once costs a little more but can save a second visit on an older heater.

Repair or replace?

Element replacement is almost always worth doing on a tank that is not leaking. If the tank is old, heavily scaled, or already leaking, put the money toward a new heater instead.

Preventing element failure

Hard water causes scale to build on elements, which makes them run hotter and fail sooner. Regular tank flushing and, in hard water areas, low-watt-density elements help them last longer.

In Texas

Hard water in much of Texas is a common cause of element failure. If you replace elements often, consider flushing the tank more regularly or treating the water.

How to tell which part has failed

Electric tanks usually have two elements and two thermostats, one set near the top and one near the bottom. The upper thermostat controls the upper element first, then passes power to the lower element once the top of the tank is hot. That design produces typical symptoms:

• No hot water at all: often the upper element, the upper thermostat or a tripped high-limit switch.
• Some hot water, but it runs out fast: often the lower element.
• Water too hot: a stuck thermostat, which should be checked right away because the relief valve may start to discharge.

A technician confirms the fault with a multimeter. Elements are tested for resistance with the power off, and thermostats are checked for voltage on the correct terminals. Replacing parts without testing can mean paying for parts that were not the problem.

The reset button

Above the upper thermostat there is a red reset button behind the access panel. If it has tripped, pushing it may restore hot water. If it keeps tripping, something is wrong, such as a shorted element or a failing thermostat, and the heater should be checked rather than reset over and over.

Doing the job safely

Element replacement requires opening a panel with exposed terminals carrying high voltage. The breaker must be off and the power confirmed off with a tester before touching anything. The tank must also be partly drained so the element can come out without a flood, and completely refilled before the power goes back on. Turning the power on with the element out of water burns it out almost instantly.

Choosing the replacement element

Elements are matched by wattage, voltage and style. Using the wrong wattage can overload the circuit or the thermostat. Low-watt-density elements run cooler and tend to last longer in hard water, where scale builds on the element surface.

What else to do while the tank is open

Since the tank is already partly drained, it is a good moment to flush sediment from the bottom of the tank. Sediment is a common reason lower elements fail. Checking the anode rod at the same time can also make sense on an older tank.

How long elements last

In soft water, elements can last many years. In hard water, scale coats the element, making it run hotter until it fails, and loose scale settles on the lower element. If you replace elements more than once in a short period, flushing the tank regularly or treating the water may save money over time. A popping or sizzling sound from an electric tank is often scale on the elements, and it is a hint that a flush is overdue. Some homeowners in hard water areas switch to stainless or low-watt-density elements for that reason.

Before you call

Check the breaker first. Then check the reset button behind the upper access panel. If both are fine and there is still no hot water, an element or thermostat is the likely cause.
