How Long Does a Water Heater Last?

Like any other home appliance, water heaters have a lifespan. Regular maintenance can keep it working reliably for many years, but eventually, every water heater needs replacing. 


As experienced plumbers in Euclid, Ohio, we receive many calls from homeowners who need help with their water heaters. Many ask us, “How long does a water heater last?” and worry about whether they’ll need to invest in a new one soon.

 

When Can You Expect to Replace a Water Heater? 


The type of water heater you have determines its expected lifespan. Tank water heaters, which store heated water and replenish it throughout the day, typically last 10 to 15 years before they need replacing. Tankless water heaters, which heat water on demand, usually last for about 20 years. 


These are just estimates, and multiple factors influence the exact lifespan of your water heater. 


Why Water Heaters Fail 


Over time, you may notice that your water heater doesn’t perform as well as it once did. This decreased performance can happen for various reasons, with wear and tear and a lack of maintenance topping the list. 


Tank Water Heater Issues

If you have a conventional or tank water heater, a lack of maintenance, or more specifically, flushing the tank to remove sediment, is the most common reason for failure. Over time, minerals in the water can settle at the bottom of the tank and accumulate. When this happens, it can contribute to corrosion that causes a leak.


Sediment build-up can also affect the heating elements in the tank. The minerals coat and insulate the heating elements and keep them from being able to heat the water efficiently. This causes the heater to work harder and use more energy to warm water, putting more wear and tear on the mechanical components. 


Flushing the tank at least once a year to remove sediment is an essential task for keeping the water heater running for many years. However, another common issue is corrosion on the anode rod, the part of the tank that protects the steel tank from rust and deterioration. If this rod corrodes, the tank can also corrode and crack, causing a leak.


Tankless Water Heater Issues 

If you have a tankless water heater, the answer to “How long does a water heater last?” depends more on your water quality than the appliance. While low-quality tankless water heaters will almost always fail sooner than a well-made model, the mineral content of the water in your area can also speed up failure. 


Tankless water heaters have more mechanical elements than conventional models and, therefore, require more ongoing maintenance to stay in good condition. Scheduling annual maintenance service to clean and inspect these components increases the likelihood of getting 20 years or more out of the unit. 


Signs of Impending Water Heater Failure 


Water heaters don’t typically fail without warning. Usually, there are signs of impending trouble well before it stops working and leaves you taking a cold shower. Sometimes, a plumber can make repairs to get the heater working again, but if the appliance is old and nearing the end of its useful life, they’ll likely recommend a replacement. 


You should plan on replacing the unit soon at any of the following signs of impending failure:


  • Discolored water. A failing water heater can make the water look dirty or rusty, a sign of corrosion inside the tank. 
  • Unreliable heating. If the water doesn’t reach the desired temperature or the heating is inconsistent, there could be an issue with the gas or electric coil, and the water heater is in its final days. 
  • Strange noises. Unusual noises, like cracking, popping, rumbling, or gurgling, can indicate hardened sediment inside the tank, causing it to work harder than it should.
  • Leaks. A leak in the water heater is a surefire sign that it’s time for a new one. Excess pressure inside the tank due to a malfunctioning valve or high-temperature setting can cause a leak.
  • Visible damage. Any visible damage, like rust, dents, or cracks, means it’s time for a new water heater, especially if the appliance is over ten years old. 


Replace Your Water Heater Before It Fails 


The last thing you want is for your water heater to fail, forcing you to shop for a new one under pressure. Now that you have the answer to “How long does a water heater last?” check the age of yours. Look for a sticker indicating the manufacturer or installation date, or use the serial number to find information about the appliance from the manufacturer. 


If your water heater is nearing the end of its lifespan or showing signs of age, start shopping for a replacement now. Doing so can save you money since you won’t have to pay emergency service fees or repair water damage that can occur when the heater breaks down. 


Shopping for a new water heater before your existing one fails also allows you to do your homework and choose the model that works best for your budget and needs. Chances are, you have had your current water heater for a decade or two and aren’t aware of the new technology and options. Instead of buying the first water heater you can find under duress, give yourself some time to identify the best choice for your money.

Dealing with a broken water heater can feel like trying to navigate a ship in stormy seas. But don't worry, you can take control of the situation with some straightforward steps. From checking the power supply to flushing the tank, these smart tips will help you get your hot water back in no time. But what if the problem is more complex than you think? Let's explore what you can do next. Identify the Symptoms of a Malfunctioning Water Heater Have you noticed anything unusual with your water heater lately? If you're experiencing inconsistent water temperatures or lukewarm water when you need hot water, it's a clear sign that something's wrong. You might also hear strange noises, like popping or humming, which could indicate sediment buildup or other issues inside the tank. Additionally, check for any leaks around the base of the unit; even small puddles can signal a serious problem. Discoloration in your water, like a rusty or brown tint, suggests corrosion or a failing tank. Finally, if you smell gas or a strange odor, it's essential to act immediately and contact a professional. Regular inspections can help detect corrosion issues early and prevent more significant problems. Recognizing these symptoms early can save you from costly repairs down the line. Stay vigilant and trust your instincts; if something feels off, it probably is. Don't hesitate to reach out for help if you need it. Check the Power Supply and Circuit Breaker Before you get into any repairs, check the power supply and circuit breaker first. Make sure the power connection is secure and examine the circuit breaker for any issues. If the breaker's tripped, simply reset it and see if that solves the problem. Additionally, ensure that your water heater is not older than 10 years, as older units are more prone to issues . Inspect Power Connection When your water heater isn't functioning, the first step is to inspect the power connection to confirm everything's in order. This confirms that power is flowing properly to your unit. Here's what you should do: Check the power cord – Make sure it's securely plugged into the outlet. Inspect for visible damage – Look for frayed wires or burns on the cord. Verify the outlet – Test it with another appliance to confirm it's working. Look for tripped GFCI outlets – Reset any that may have tripped, affecting the power supply. Examine Circuit Breaker Checking the circuit breaker is essential in diagnosing your water heater issues. Begin by locating your electrical panel and inspecting the breakers. Look for any that are in the "off" position or have a tripped appearance. If you find one, it could mean your water heater isn't receiving power. It's vital to guarantee that the breaker supplying power to your water heater is functioning correctly. If it's not tripped, you might still want to reset it by turning it off and then back on. Be cautious and check for any signs of damage or wear on the breaker itself. If you're unsure about the process, don't hesitate to consult a professional for assistance. Your water heater needs reliable power to function efficiently. Reset Tripped Breaker After inspecting the circuit breaker, you may find that it's tripped, which can prevent your water heater from getting power. Resetting it's often a simple fix. Here's what you need to do: Locate the breaker panel – It's usually in a basement, garage, or utility room. Find the tripped breaker – It'll be in the "off" position or in the middle. Reset the breaker – Flip it fully to the "off" position and then back to "on." Check your water heater – If it powers on, you're good to go; if not, further troubleshooting may be needed. Inspect the Thermostat Settings To guarantee your water heater is operating at its best, it's essential to inspect the thermostat settings regularly. Start by checking the temperature setting; it should typically be around 120°F for peak performance. If it's set too low, you mightn't get enough hot water, while a higher setting can lead to scalding and increased energy bills. Next, make sure the thermostat is functioning properly. You can do this by adjusting the temperature and observing if the water heats up accordingly. If you notice inconsistencies, the thermostat may need replacement. Lastly, don't forget to check for any wiring issues or loose connections that could affect the thermostat's performance. Regular inspections can help prevent common plumbing issues that lead to costly repairs and ensure your water heater operates efficiently. Taking these steps can help you maintain a consistent hot water supply and prolong the lifespan of your water heater. Regular inspections save you time and money in the long run! Examine the Water Heater Tank for Leaks Maintaining your water heater's performance goes beyond just inspecting the thermostat; it's also important to examine the tank for leaks. Leaks can lead to significant damage and higher utility bills, so don't overlook this critical step. Here's how to check for leaks effectively: Inspect the Tank Exterior : Look for any signs of moisture or water pooling around the base of the tank. Check Connections : Examine all inlet and outlet connections for drips or corrosion. Look for Rust or Corrosion : Pay attention to any rust spots on the tank, as they can indicate a potential leak. Listen for Sounds : If you hear hissing or dripping noises, this might signal a hidden leak that needs immediate attention. Additionally, remember that corroded water pipes are a common cause of leaks, so be vigilant in your inspections. Flush the Tank to Remove Sediment Buildup Flushing the tank regularly helps remove sediment buildup that can hinder your water heater's efficiency. When minerals and debris accumulate at the bottom, they can cause overheating and reduce the effectiveness of your heater. To flush the tank, first, turn off the power supply and close the cold water inlet valve. Connect a garden hose to the drain valve at the bottom of the tank and place the other end in a suitable drainage area. Open the drain valve and allow the water to flow out. As the tank empties, you may notice sediment being washed away. Once the water runs clear, close the drain valve, remove the hose, and reopen the cold water inlet valve to refill the tank. Don't forget to turn the power back on. Regular flushing can extend your water heater's lifespan and improve its performance, so make it a part of your maintenance routine. Replace the Anode Rod for Longevity To keep your water heater running smoothly, you can't overlook the anode rod. This essential component helps prevent corrosion inside the tank, extending its lifespan considerably. Make it a habit to check and replace the anode rod every few years to guarantee peak performance. Importance of the Anode Rod An anode rod is an essential component of your water heater, playing a crucial role in preventing corrosion and extending its lifespan. By attracting corrosive elements, the anode rod sacrifices itself to protect the tank. Here's why you should prioritize its maintenance: Corrosion Prevention : It helps prevent rust from forming inside your tank. Extended Lifespan : A well-maintained anode rod can greatly prolong the life of your water heater. Cost Efficiency : Replacing the anode rod is cheaper than replacing the entire unit. Improved Efficiency : A healthy rod enhances the overall efficiency of your water heater, saving you money on energy bills. Regularly checking and replacing your anode rod is a smart investment for long-lasting hot water comfort. Replacement Frequency Guidelines Regular maintenance of your water heater includes checking the anode rod to confirm it's in good condition. This rod plays a vital role in preventing corrosion, and replacing it every three to five years is a smart practice. However, if you notice significant corrosion or a foul smell, it's time to replace it sooner. For homeowners in Wickliffe, OH, keeping an eye on the anode rod helps extend the life of your water heater and can save you from costly repairs down the line. When you replace the anode rod, choose a high-quality magnesium or aluminum option for the best protection. By staying proactive with this simple task, you guarantee your water heater operates efficiently and lasts longer. Call a Professional for Complex Repairs When dealing with complex repairs like a broken water heater, it's essential to recognize when to call in the professionals. Tackling these issues on your own can lead to further damage or safety hazards. Here are some signs it's time to reach out to an expert: Leaking Water : If you notice significant leaks, it could indicate serious internal damage. Unusual Noises : Banging or popping sounds often signal sediment build-up or mechanical failure. Temperature Issues : If your water isn't heating properly or fluctuates wildly, a professional can diagnose the problem. Old Age : If your heater is over ten years old and showing signs of wear, it's best to consult a technician. Calling Formica Plumbing & Sewer Co. guarantees you get reliable, expert service. Their licensed professionals are ready to handle your water heater woes with care and efficiency.
