Q. We just bought a house, and the previous owners told us that the water heater is about 6 years old. Does that mean we’ll have to replace it soon? How long do water heaters last?

A.As long as it is still heating water enough and there are no leaks or weird noises, you should be able to get a few more years out of it. The usable life of a water heater varies based on the kind of water heater, the quality of the device, and how well it has been maintained. When it comes to water heaters, you may be thinking, “How long do they last?” Continue reading to learn about the indications of aging and what to consider when replacing an old water heater.

A Water Heater’s Life Expectancy

There are a variety of elements that influence the life expectancy of a water heater. In addition to the age of the water heater and whether or not it receives regular maintenance, the quality of the water and the amount of water that is used on a regular basis have an impact on its longevity. However, while a water heater may be able to outlive normal projections, there are expectations for how long a water heater will survive dependent on the type of water heater used.

A traditional tank-type water heater lasts an average of 8 to 12 years.

An anode rod is installed within the tank to preserve the internal lining by drawing all corrosive particles to itself through a process known as electrolysis, which is performed on the rod. The particles from the rod’s corrosion accumulate in the bottom of the water tank, where they may ultimately degrade or damage the tank’s lining. When this occurs, the rod is no longer effective at its task. Once corrosion begins to occur within the tank, the water heater has reached the end of its useful life.

A tankless water heater can last up to 20 years, sometimes even longer.

Known as “on-demand” water heaters, these appliances do not operate continually to ensure a constant supply of hot water, allowing them to survive far longer than their tank-style counterparts in the process. Tankless water heaters (which do not employ anode rods) may, at some point, succumb to corrosion and need to be replaced as a result.

Your existing water heater’s serial number holds the clue to its age.

The serial number of your water heater, which consists of a letter followed by a series of numbers and is situated on the upper section of the water heater, can help you establish when it was made even if you can’t locate the original documentation for your appliance at the time of purchase. Typically, the letter represents the month—for example, “A” represents January, “B” represents February, and so on, up to “L” representing December—and the next two digits represent the year it was created.

This rule of thumb applies to the majority of hot water heater manufacturers, but if you have any questions, you may double-check the information on the company’s website.

Signs Your Water Heater Might Be on Its Last Legs

It’s necessary to monitor the performance of your hot water heater on a frequent basis to ensure that it’s operating at peak efficiency.

This goes beyond simply following the manufacturer’s maintenance recommendations. However, even if allappliances have an average lifespanbased on regular use, it is recommended that you begin looking for a replacement as soon as you observe any of the following indicators of wear and tear.

  • When a water heater is nearing the end of its useful life, it is common to hear banging or rumbling sounds. Few individuals actually follow the manufacturer’s recommendation to flush a tank-style water heater on an annual basis, resulting in calcium buildup from hard water collecting at the bottom of the tank. This is a necessity for maintaining the warranty on the water heater. It builds up, hardens, and finally solidifies into a thick crust, which can cause the water heater to creak and bang when in use
  • The hot water also has an unusual scent to it. If the hot water has a strange odor or flavor to it, it is possible that something is polluting the water storage tank. Metal that has been absorbed by the water or bacteria that has gathered inside the tank might be the cause of this odor. Alternatively, if cleaning the tank does not resolve the issue, it may be necessary to hire a plumber. Rust might be present in any faucet that produces tinted hot water, whether it be red or filthy yellow. It’s critical to evaluate whether the discolouration shows while the cold water is flowing as well as when it’s not. A corrosion problem is more likely to begin inside the water heater rather than within any rusting galvanized pipework, if this is the case
  • It is possible that the water temperature will decline. This indicates that the water heater is approaching the end of its service life if the water does not heat up as quickly or does not remain at the correct temperature for as long as it once did
  • There is less hot water available than in the past. Over time, silt can accumulate inside the water tank, reducing the amount of space available for water storage within the tank. If the hot water is running out more quickly, it is possible that the tank has to be emptied and cleaned. If you wait too long to clean the tank, it may be necessary to replace it. The presence of water accumulating around the base of a water heater tank is also a bad omen. First, verify sure the leak isn’t coming from a fitting or valve that simply needs to be tightened or replaced by a qualified professional. Engage the services of an expert to investigate the issue and conduct any necessary maintenance. If you discover that the source of the leak is the tank itself, it is possible that the tank is fractured or rusted within. The hardness of the water is influencing the quality of the water. Using hard water can cause significant damage to a water heater, reducing its service life by two or more years. If you find white limescale accumulating on plumbing surfaces, it is possible that the water heater may need to be changed more frequently. The location of the heater might have an impact on its longevity. Garages and crawl areas, where the temperature lowers dramatically, need the use of more energy to heat the available water, resulting in a shorter lifespan than units installed in a climate-controlled home. It is recommended that you begin looking for end-of-life warning indications sooner than the manufacturer suggests if either of these factors applies to your system.

Planning Ahead to Replace a Water Heater

A hot water heater replacement is not an uncommon undertaking, but it is one that requires careful preparation and consideration. Depending on whether you have a regular tank water heater or a specialist electric tankless water heater, the time it takes to order a replacement might differ. Additionally, scheduling a time with a professional plumber to make the switch when it is not an emergency will save you money on additional installation expenses. Most importantly, knowing the precise hot water heater that will be needed before the present one reaches the end of its useful life may help the procedure run much more easily and efficiently.

Think 2 years beyond the predicted lifespan of your water heater.

When considering the normal water heater life expectancy for the present model, keep the following in mind: A tank-style water heater should be replaced when it reaches the age of 8 to 10 years, and a tankless water heater should be replaced when it reaches the age of 15 to 18 years. The inconvenience of a broken pipe and the inconvenience of running out of hot water will be avoided, and excess energy consumption will be minimized as a result of these measures.

Take advantage of the energy-saving tech features newer models offer.

After several years of use, either kind of water heater is susceptible to mineral deposits and silt accumulation, which can increase the amount of energy required to heat the water, hence decreasing the overall efficiency of the device. Install a replacement, on the other hand, and the combination of a decade’s worth of technological advancements and the new model’s clean interior will almost certainly result in a reduction in your power bill in the months to come.

Start looking for a new water heater before it’s needed.

The procedure of replacing a water heater might become more complex and expensive if you wait until it becomes an emergency or is exceedingly inconvenient. If your present water heater is exhibiting symptoms of wear and tear, begin investigating replacement choices and speaking with a professional about arranging an appointment for an evaluation and possible replacement. A conventional water heater can be delivered in a few days and replaced in a few hours by a professional, but having a plan in place before your water heater breaks can be extremely beneficial.

Call the manufacturer if the water heater is still under warranty.

While a variety of problems might indicate that a water heater is nearing the end of its useful life, if your unit is only a few years old, the problem may be repairable and covered by the manufacturer’s warranty. Before purchasing a new appliance, it may be worthwhile to contact the manufacturer or a plumber to have the item inspected. Repairing an older unit will also provide you more time to choose a replacement unit when the time comes. RELATED:Solved! How to Choose the Most Appropriate Water Heater Sizeistockphoto.com

How long do water heaters last?

To answer this issue simply, the typical age of a water heater is determined by the quality of the water available in your area, how frequently you use it, and how frequently it is maintained. The following are some of the factors that influence the life expectancy of a water heater:

  • The sort of water heater you have and where you are located are as follows:
  • While many people believe that a normal gas-powered water heater has an estimated life of 8 to 12 years, this range can vary and is highly dependant on where you live. The amount of sediment in your water heater’s tank has an impact on its longevity. If you live in a location with sediment-heavy water, this will significantly reduce the lifespan of your vehicle. The average life lifetime of electric vehicles is somewhat longer than that of gasoline vehicles.
  • The regularity with which a water heater is maintained has an influence on how long it lasts. It is essential that you maintain it on a regular basis to ensure that it remains in good shape. Tank vs. tankless: Which is better? Because tankless heaters do not have to deal with the stress of storing and heating water (even when not in use), they can survive up to twice as long as typical gas or electric storage heaters

How Long Does a Water Heater Last?

Maintaining your water heater will ensure that it operates at peak efficiency for the longest possible time. You must, however, be aware of when it is necessary to replace your current one. As a result, you should be able to conduct simple activities such as flushing your water heater or relighting the pilot light on your stove. But other folks are uncomfortable with the idea of fiddling with their water heater. In this scenario, you should consult with a plumbing professional who can ensure that your hot water heater remains in good working order at all times.

  1. If the pressure in your water heater becomes too high, the relief valve will open to relieve the pressure.
  2. As a result, you need be aware of how to drain a hot water heater in order to keep it in perfect working order.
  3. For example, you should be wearing protective clothes such as gloves, goggles, and thick clothing to keep you from being burned while working.

How to Flush a Water Heater

Sediment can have a negative impact on the functioning of your water heater over time. Sediment lowers the performance of your water heater’s heating element. It can possibly cause a blockage in your water lines as well. Every time you check your water heater pressure relief valve, clean the tank to extend the life of the water heater and prevent issues from developing. Pour water into the tank and direct it to a location where it won’t cause harm before starting the project. Ensure that the pressure relief valve is closed before opening the drain valve and allowing the tank to completely empty.

Open all of the hot water faucets and turn on the cold water to the tank to start the process.

You may now switch on the power and, later, the natural gas.

Reigniting the Pilot

The pilot should be re-ignited by turning on the gas valve and turning the control knob to “Pilot.” Whenever the water heater is turned on, a light should blink. By looking through the windowpane, you may see a little flame, which indicates that the pilot has been ignited. Set the temperature to around 120 degrees Fahrenheit at this point. Remember to always refer to the manufacturer’s instructions for further information on how to ignite your pilot. In the case of a modern water heater, the pilot light may be tiny and difficult to notice.

Condensation may form on the surface of your water heater when it is initially turned on. Condensation is natural and will subside as soon as your water heater begins to heat up.

Remember that there are two basic types of water heaters, each with a varied lifespan, which you should know about. There are two types of water heaters: tankless and tank storage. Because they act in various ways, their lifespans differ. Tank water heaters heat water continually, whereas tankless water heaters heat water just when it is required.

Among the issues we’ll explore in this post are the ones listed below:

  • How long should a water heater be expected to last? Factors that might shorten the life of your water heater include: When should your water heater be replaced? Instructions on how to replace a water heater

How Long Do Water Heaters Last?

Regardless of whether they are tank or tankless, all water heaters are built to survive for more than 10 years. Ultimately, how well you maintain your heater will determine its longevity. Identifying common problems and resolving them as soon as possible will significantly increase the lifespan of your water heater.

Lifespan of Tank Water Heaters

Water heaters with a traditional tank design can endure for an average of 8 to 12 years. However, if it is used and maintained properly, it may endure for up to 15 years or even longer. The tank is equipped with an anode rod, which draws corrosive substances in the water and prevents corrosion of the tank’s inside lining. After utilizing the tank water heater for a long period of time (about 10 years), the rod becomes corroded and no longer functions properly. It is the corrosive particles that accumulate on the tank’s internal lining, especially the tank’s bottom, that ultimately cause it to fail.

Lifespan of Tankless Water Heaters

Tankless water heaters employ innovative technology that allows them to survive far longer than traditional tank water heaters. Generally speaking, the life expectancy of these heaters is 20 years. Some, on the other hand, can endure for up to 30 years if they are properly maintained. The capacity of this type of heater to heat water only when it is required has given it the nickname “on-demand water heater.” When compared to tank water heaters, they don’t have to operate all of the time to keep the water warm, which increases their longevity.

How Long Should a Water Heater Last? Determining Age

Now that you know how long each type of water heater is expected to last, you can estimate the year in which you will need to replace it. However, it is only achievable if you are aware of the age of the object. What happens if you purchase a property that has a used water heater and you don’t know how old it is? When you buy a used water heater, how will you know how old it is? It is necessary in that situation to look up the machine’s serial number, which is comprised of a letter followed by a series of numbers.

To symbolize the month of December, the letters can only reach as high as the letter ‘L.’ Consider the following example: if you come across a water heater with the serial numberA11 0297340, the letter “A” stands for January, which is the first month of the year, and the first two numerals “11” stand for the year 2011, respectively.

Inquire with the manufacturer of your water heater to see whether or not they adhere to this standard. If not, they may be able to determine the age of your heater through other techniques.

How Long Should a Water Heater Last? Factors to Consider

There are a few elements that can have an impact on the longevity of a water heater, both favorably and adversely.

  • Water Quality: If the water heater is forced to heat hard water more frequently, its lifespan will most certainly be reduced by around two years. Hard water includes minerals that can cause limescale to build up in your water heater, lowering the effectiveness of the appliance. In order to prevent minerals from reaching equipment such as your water heater, water softeners are used. Practices for preventative maintenance include: If you do not perform regular repairs and maintenance on your water heater, it may eventually fail after a few years of service. Water heaters that are properly maintained, on the other hand, might live much longer than predicted. If you want plumbing services in Gilbert, you can reach out to us for water heater tune-ups and repairs, among other things. The following is the material of the Water Heater: Water heaters constructed of high-end materials such as fiberglass have a longer lifespan than those constructed of less expensive materials such as steel. Water heaters can be powered by either electricity or natural gas, depending on the manufacturer’s recommendations. Generally speaking, electric-powered water heaters have a longer lifespan than gas-powered water heaters by around 1-2 years. Installation Site: If you put your water heater in a chilly crawl area, the machine will have to work harder to keep the water at the temperature you want it to be. You may expect it to wear out quickly and eventually fail. Water heaters that are put in temperature-controlled houses tend to live longer than those that are not.

When Should You Replace Your Water Heater

When your water heater reaches the age of ten, you’ll be able to recognize the warning signals that it’s on the verge of failing. Some water heaters, on the other hand, may fail after only a few years of use. A number of factors can contribute to your water heater failing unexpectedly, including the following:

  • Buildup of Sediment: Because a tank water heater warms and reheats repeatedly, impurities may accumulate at the bottom of the tank and harden over time, speeding up the deterioration of the heater and decreasing its effectiveness. Over-pressurization: This condition happens when the pressure of water in a tank water heater exceeds the maximum allowable, causing the water heater to malfunction and fail. A significant element contributing to over-pressurization in the tanks is excessive heating
  • However, there are other contributing variables as well.

Signs to Watch for to Replace Water Heaters

Now, let’s take a look at some of the things you should be on the lookout for when utilizing your water heater. When you see any of the above indicators, it is time to start thinking about purchasing a new water heater. Your water heater will begin to make unusual noises as time goes on, and you will begin to notice them anytime the unit is heating the water. When you use a lot of hot water in your home on a regular basis, the pounding sound may become much more audible in your home. Sediment accumulates in the bottom of the tank, which is the major source of this phenomenon.

  • In order to avoid sediment building at the bottom of the water heater tank, the majority of manufacturers recommend that you clean it once a year.
  • Despite the fact that the majority of tank water heaters are composed of stainless steel, they are susceptible to rusting.
  • The pressure relief valve, water intake connection, and water outlet connection are all susceptible to rust or corrosion if not properly maintained.
  • It is your only choice to have it replaced.
  • When a water heater begins to deteriorate from the inside, it is common for it to leak.
  • Tankless water heaters are a good choice if you want to avoid leaks.

Estimating the Lifespan of a Water Heater

Nick Gromicko, CMI®, and Barry Fowler contributed to this article. A water heater has a lifespan of around 10 years, but thorough evaluation of the elements that influence its longevity can offer the InterNACHI home inspector and the homeowner with information about the possible expenses associated with replacing the water heater. These considerations include the following: proper installation, amount of usage, building quality, and upkeep. Installation Done Correctly It is recommended that water heaters be positioned upright in well-ventilated locations, not only to meet fire safety regulations and prevent carbon monoxide accumulation, but also because inadequate ventilation can reduce the lifespan of the water heater.

  1. Water can corrode the unit’s exterior and pipes, shortening the unit’s life expectancy and diminishing its efficiency.
  2. It should also be easily visible in order to comply with fire and health hazard regulations.
  3. The installation of tankless gas water heaters, for example, takes more skill than the ordinary do-it-yourself project, despite the fact that homeowners can save money by doing it themselves.
  4. Usage When it comes to water heater life expectancy, the amount of water utilized makes a significant difference.
  5. Furthermore, the bigger the amount of water, the greater the corrosive effect of the water will be on the surrounding environment.
  6. In the case of a water heater, as with most other household systems and components, you get what you pay for.
  7. The guarantee that comes with a water heater is an excellent indicator of the quality of its construction.

The findings of a 2007 Consumer Report, which disassembled 18 different models of water heaters, revealed that models with longer warranties were invariably of higher manufacturing quality, with models with nine- and 12-year warranties typically having larger or higher-wattage heating elements, as well as thicker insulation.

  1. Pay close attention to the model’s characteristics.
  2. Some versions are equipped with a self-cleaning mechanism that removes mineral deposits from the pipes, which is an essential element for determining the unit’s lifespan.
  3. Maintenance and Replacement Parts Replacement When attempting to estimate the lifespan of a water heater, it is important to take the hardness of the water into mind.
  4. Although mineral deposition is less likely to occur in locations with softer water, it is inevitable in all areas.
  5. This not only eliminates some of the buildup, but it also warms the water in the tank, which is particularly useful in tank systems.
  6. It is critical not to damage the water heater valve on versions that require manual flushing since the valve is often constructed of plastic and is easily broken when the water heater is turned on.
  7. Given that labor expenses are frequently excluded from warranty coverage, it’s a fair rule of thumb to follow: if the total repair cost each year exceeds 10 percent of the overall cost of purchasing and installing a new water heater, it’s generally not worth repairing broken parts.
  8. It is easy to damage the unit during the difficult process of emptying the tank and changing the anode, and because anode replacement can void some warranties, the expense of future repairs or maintenance that would otherwise be covered must be taken into consideration.

After looking for obvious signs, such as a puddle under the heater or ice cold showers in the morning, that indicate that a new water heater is needed, the homeowner should take into account the manufacturer’s age and warranty, as well as the cost-benefit analysis of maintaining an existing heater as opposed to purchasing a new one.

How Long Do Water Heaters Last [2022 Homeowners Guide]

No one enjoys taking a cold shower. This is especially true during our bitter Minnesota winters. Keep an eye on the health of your water heater is a key concern for a large number of homeowners. Water heaters, on the other hand, endure for how long? When should a homeowner anticipate that their water heater may break down? What are the indicators that your water heater is beginning to fail? It is very dependent on the sort of water heater you have, as well as how well you keep it maintained. Let’s get started and obtain some more detailed answers.


There are various factors to consider when determining how long your water heater will survive and when to replace your water heater. Water that is colored or chilly, as well as clanking noises emanating from the device, are all indicators of a failed water heater, which we’ll discuss further later. With regular maintenance and servicing, a new water heater will typically last 12 years on average, give or take a year or two on average. Although there are several elements that influence how long your hot water heater will survive, these little-known statistics are among the most important.

  • Tank vs. tankless water storage
  • Quality of your water (hardwater can reduce lifetime by 2 years or more)
  • And the location of your home or business. How frequently you utilize it
  • In case it is improperly installed in a crawl area or basement, where it will take longer to warm up

The longevity of your water heater is also determined by the type of water heater you have. Tank water heaters have an average lifespan of 8 to 12 years, but tankless water heaters have a lifespan of up to 20 years and are more energy efficient. There are both electric and gas water heaters, and their lifespans can vary, but in general, gas water heaters will last 8-12 years, whilst an electric water heater could live up to 10-15 years on average.


There are a few telltale signals that it is time to replace your hot water heater that you should be aware of. First and foremost, if your water heater is more than ten years old and you are experiencing any of the following symptoms, it is likely that your water heater is nearing the end of its life.


Inadequate hot water coming out of your taps or shower is one of the first symptoms that your hot water heater is malfunctioning. You may notice that when you turn on the shower, you are only getting cold water after a few minutes. This might be a symptom of excess sediment or mineral deposits in your water heater. In the final stages of its service life, a water heater has difficulties maintaining a constant temperature of the water. If you find that your hot water is running out rapidly, it is possible that your water heater is too old to continue to function effectively.


In older appliances, sediment can accumulate at the bottom of the water tank, causing the heating components that provide regular hot water to become ineffective. Large quantities of silt building reduce the amount of space available for water in the tank. Sediment accumulation can also be a tell-tale indicator of a failing water heater: the calcium deposits solidify and form a thick crust on the water heater’s surface, causing the water heater to creak and rumble while the water heater is in operation.

In order to ease the problem, you can hire a repair person to clear out the sediment and flush your system, which may be necessary. If the appliance is more than a decade old, it may be prudent to consider replacing it.


Another prevalent problem, particularly in tanks that have not been adequately maintained, is the wear and tear that occurs over time. If you notice that your water heater is leaking or makes banging noises, it’s a solid indication that it’s no longer functional. Aside from that, if your water heater is more than 10 years old and your faucets are running with rusty water, it’s time to replace it. Water heater repair may be quite expensive, and there are frequently multiple parts that need to be replaced.


More warning indications should be kept an eye out for in addition to the three previously mentioned indicators. If you observe any of the following problems, contact a reputable plumber as soon as possible:

  • A large amount of water is accumulating around the base of the heater
  • Limescale accumulation on the surfaces of plumbing fixtures
  • Water that has been tinted red or yellow
  • Hot water that smells or tastes strange


When considering factors such as longevity, location, usage, and hard water, you may make an educated guess as to how long your hot water heater will survive. According to industry experts such as Bob Vila, replacing your hot water heater before it reaches the end of its anticipated lifespan may be a smart idea.


It is possible that replacing your hot water heater at least two years before it fails can save you a great deal of pain and inconvenience. When your tank-style hot water heater reaches the age of 8 to 10 years, it’s time to think about replacing it. When your tankless water heater reaches the age of 15 to 18 years, you should do the same thing. If you realize your water heater is reaching the end of its useful life, you may prevent the surprise expenditure and plan ahead for a replacement. You will also avoid the inconvenience of being without hot water while you wait for the problem to be resolved.


As the years pass and newer models are introduced, it is likely that your ten-year-old water heater has been less efficient than any newer type for a significant period of time already. It’s probable that your water heater is either not fulfilling standards or is at the very least increasing your electricity expenses needlessly as a result of its inefficiency. When you update to a newer brand of water heater, you will discover that the technical advancements that have occurred in the meanwhile will result in a reduction in your utility cost that is noticeable immediately.


If your water heater is still under warranty, it’s never a bad idea to get in touch with the manufacturer. If your water heater is only a few years old, the problem may be covered by the manufacturer’s warranty, saving you a significant amount of money.

Before making the decision to purchase a new water heater, contact the manufacturer to see if you can purchase any additional time before needing to replace it.


With water heaters, you don’t want to take any chances and choose anything that’s too inexpensive to function well. Brands do, in fact, matter.
