Understanding the Role of Heating Elements in Your Water Heater

Electric water heaters rely on one or two heating elements to warm the water stored in the tank. These elements are essentially thick metal rods that are immersed in water and controlled by thermostats. When you turn on a hot water tap, the thermostat detects the drop in temperature and signals the heating element to turn on, ensuring a steady supply of hot water.

Most standard electric water heaters have two elements: an upper and a lower. The upper element heats the top portion of the tank first, and once it reaches the set temperature, the lower element kicks in to heat the bottom. If either element fails, you may experience a lack of hot water, inconsistent temperatures, or other performance issues.

Gas water heaters, by contrast, use a burner and do not have electric heating elements. If you have a gas unit and are experiencing hot water issues, the problem likely lies elsewhere.

Signs and Symptoms of a Faulty Water Heater Element

Recognizing the signs of a bad heating element is the first step toward a solution. Here are the most common symptoms to watch for:

1. No Hot Water

If your electric water heater isn’t producing any hot water at all, it’s possible that both heating elements have failed or that there is a problem with the electrical supply. However, a single failed element can also cause a total loss of hot water if the thermostat is only activating the non-working element.

2. Insufficient Hot Water

When you notice that the water is only lukewarm or runs out quickly, it’s often a sign that only one of the two elements is working. Typically, if the lower element fails, you’ll get a small amount of hot water that quickly turns cold. If the upper element fails, you may get no hot water at all.

3. Water Takes Too Long to Reheat

A properly functioning water heater should recover and reheat water within a reasonable time frame. If it’s taking much longer than usual, a failing element may be to blame.

4. Fluctuating Water Temperatures

If your hot water temperature is inconsistent or fluctuates between hot and cold, this can indicate an intermittent or partially failed heating element.

5. Tripped Circuit Breaker or Blown Fuse

A shorted heating element can cause your water heater’s circuit breaker to trip or a fuse to blow. If this happens repeatedly, it’s a strong indication that one of the elements is faulty.

6. Strange Noises

While not as common, a failing heating element can sometimes cause popping, hissing, or sizzling sounds as it struggles to heat water or burns out.

Step-by-Step Guide: How to Test Your Water Heater’s Heating Element

Testing your water heater’s heating element is a straightforward process if you’re comfortable working with basic tools and electrical components. Always prioritize safety—if you’re unsure at any point, contact a professional.

Tools You’ll Need

• Phillips and flathead screwdrivers

• Digital multimeter (for continuity testing)

• Safety gloves and goggles

1. Turn Off Power to the Water Heater

Before you begin, locate your home’s electrical panel and switch off the circuit breaker that supplies power to the water heater. Double-check that the power is off by testing the water heater’s wiring with a non-contact voltage tester.

2. Access the Heating Elements

Most electric water heaters have two access panels (upper and lower) on the side of the tank. Remove the screws holding the panels in place and gently pull back any insulation to expose the thermostats and heating elements.

3. Locate the Heating Elements

You’ll see the heating elements attached to the tank, usually with two wires connected to each. Take note of which element you’re testing (upper or lower).

4. Disconnect the Wires

Carefully disconnect the wires from the heating element terminals. You may need to use a screwdriver to loosen the screws.

5. Test for Continuity with a Multimeter

Set your digital multimeter to the lowest ohms setting (Ω). Place one probe on each terminal of the heating element. A good element should show a reading between 10 and 30 ohms, depending on the wattage and model. If the reading is very high (infinite resistance) or zero, the element is faulty and needs replacement.

6. Check for a Short to Ground

With the wires still disconnected, place one probe on one terminal and the other probe on the metal base of the element. The multimeter should read “OL” (open line) or show no continuity. If there is continuity, the element is shorted and must be replaced.

7. Reassemble the Water Heater

If the element is good, reconnect the wires, replace the insulation and access panel, and restore power. If the element is bad, proceed to replacement or call a professional for help.

How to Replace a Faulty Water Heater Heating Element

If you’ve determined that your heating element is faulty, replacing it is a manageable DIY project for many homeowners. However, it does require careful attention to safety and detail.

1. Turn Off Power and Water Supply

Ensure the power is off at the circuit breaker. Shut off the cold water supply valve to the water heater.

2. Drain the Tank

Attach a garden hose to the drain valve at the base of the tank. Open the valve and allow enough water to drain so the level is below the element you’re replacing. Open a hot water tap in your home to allow air into the system and speed up draining.

3. Remove the Faulty Element

Use a heating element wrench or a large socket wrench to unscrew the element from the tank. Be prepared for some residual water to spill out.

4. Install the New Element

Insert the new heating element into the tank and tighten it securely. Make sure the rubber gasket is properly seated to prevent leaks.

5. Reconnect Wires and Refill the Tank

Reconnect the wires to the new element. Close the drain valve and turn on the cold water supply. Allow the tank to fill completely before restoring power. Turn on a hot water tap to let air escape from the system.

6. Restore Power and Test

Once the tank is full, switch the circuit breaker back on. Allow the heater time to warm up and test for proper operation.

Causes of Heating Element Failure

Understanding why heating elements fail can help you prevent future issues. The most common causes include:

Sediment Buildup

Minerals in the water can settle at the bottom of the tank and around the heating element, causing it to overheat and burn out prematurely. Regularly flushing your tank helps minimize this risk.

Dry Firing

If the heating element is turned on when it’s not fully submerged in water (for example, after draining the tank and forgetting to refill it before restoring power), it can overheat and fail almost instantly.

Corrosion

Over time, the metal in the heating element can corrode, especially if the anode rod is depleted or if you have particularly hard or corrosive water.

Electrical Issues

Loose connections, faulty thermostats, or power surges can cause the element to short out or burn up.

Age and Wear

Even with proper maintenance, heating elements have a finite lifespan. Most last between 6 and 10 years, depending on usage and water quality.

If you suspect any of these issues are affecting your water heater, schedule a professional inspection and maintenance service or call 833-864-6908.

Preventive Maintenance Tips for Water Heater Elements

Regular maintenance is the best way to extend the life of your water heater and its heating elements. Here are some tips:

Flush the Tank Annually

Sediment is the enemy of heating elements. Draining and flushing your tank once a year helps remove mineral buildup and keeps your elements working efficiently.

Check the Anode Rod

The anode rod attracts corrosive minerals, protecting the tank and elements from rust. Inspect it every two to three years and replace it if it’s significantly depleted.

Inspect Wiring and Connections

Loose or corroded wires can cause electrical issues that damage heating elements. Periodically check all connections for signs of wear or burning.

Set the Thermostat Properly

Keeping your thermostat at 120°F not only saves energy but also reduces stress on the heating elements.

Look for Signs of Trouble

Pay attention to changes in water temperature, recovery time, or unusual noises. Early detection can prevent major problems.
