Essential appliances that provide hot water for daily activities are water heaters. As they get older, they may show some signs of age and inefficiency. A common indication of a failing water heater is an increased energy bill. Another indication could be your water heater making some unusual noises. Inspect the system if these noises have gotten your attention and led you to think replacement may be necessary. Sounds you should pay attention to include:
• Popping or banging
• These two sounds could indicate the water is boiling due to excessive temperature or pressure. They could also mean that sediment has built up in your water heater.
Water that is discolored or rusty can indicate an issue with the water heater's tank. This can signal that corrosion or rust is forming inside the tank. When this happens, it often leads to water quality problems and potential leaks. Leaks are usually a sign of a more serious issue, like internal tank decay. If you notice water pooling around the unit, it's an emergency situation that requires immediate attention. Letting leaks go unfixed can lead to damage in your home.
Changing water temperature is yet another sign that your water heater is on the way out.
If you're getting inconsistent hot water, that's a sign that the system is possibly failing electrically. If you're not getting inconsistent hot water, then the heater is obviously not functioning at all! But what causes an inability to maintain a range of temperatures necessary to create "hot" water? This is rounded up to a few possible plumbing and electrical issues faulting things like the heating elements, the thermostat, or even the sediment build-up affecting the heating elements appropriately (when they were supposed to be doing their job). Knowing when to get something replaced or upgraded will save you money in the long run!
It is critical to recognize when it is time to change out your water heater, to keep your house running efficiently and effectively. One of the main signs to look for is—believe it or not—the age of your water heater. Most standard ones last around 8 to 12 years. If yours is of that era or older, you should be having some serious discussions with yourself about replacing it. They get riskier as they go on, not to mention more inefficient, and who knows how much more that's costing you on your energy bill.
A different factor that is no less significant is the performance and reliability of a water heater. If it has any common issues, such as inconsistent water temperatures, a lack of hot water, or visible rust in the water supply, these are pretty clear indicators that the unit is no longer functioning as it should. More often than not, these problems are a sign of internal deterioration. And that deterioration can result in repairs that, if we invest in them, will be much more costly than if we had just made the efficient choice and replaced the unit. Strange noises coming from a heater, which can indicate sediment buildup, are also very helpful indicators. Monitoring these signs can help in deciding whether to replace a unit.
Finally, the general efficiency of the water heater must be taken into account and how that affects the house. Older units used much more energy, driving up bills in all but the warmest months. Swapping out an ancient behemoth for a modern, efficient unit could save you appreciable amounts of money over several years. Then there are the performance aspects: electric models can swing the pendulum back in favor of tankless systems with regards to capacity (because low-flow demands are no longer the bottleneck they once were) and, more importantly, speed. Water warmed with electricity will tend to be warmer and warmed more quickly than water heated by, say, a propane burner. To put it in simple terms: electric heating tends to be more efficient than other methods.

The average life expectancy of a water heater is around 8 to 12 years. After that, they're more likely to wear out and become inefficient and energy-wasting. If your unit is getting close to that lifespan—or has already exceeded it—it might be time to think about replacing it. Regular maintenance checkups can help determine its current condition and assess how much life it might have left.
When you notice rusty water coming from your taps for hot water, it could mean your water heater is corroding inside. Once rust sets in, it'll only be a matter of time before the thing starts to leak. To see if the rusty problem is coming from the water heater, drain a few buckets of water directly from the tank. If the water seems to be reproducing the issue, you're probably better off replacing the whole unit.
As water heaters get older, sediment can accumulate in the tank. When the appliance heats and reheats, the sediment hardens, and the result can be rumbling or banging noises. This is not a good sound, and it is a pretty clear indicator that your water heater is not operating efficiently and is on its way to a slow death. Regular flushing of the tank may help, but if the heater continues or worsens in its noise output, you may just need to replace it.
You may be experiencing inconsistent hot water or are running out of it altogether. There are two possible reasons for this. Your water heater may simply be too small for your needs. (It is quite common, especially in older homes, to find that the water heater is only supplying the amount it's supposed to to meet the demand of the plumbing fixtures in the house. This doesn't always mean the heater is functioning consistently. It is more a matter of the 'heating portion' of the water heater meeting plumbing demands. If you have a tub, for example, which heats better in the vertical position, sometimes it's best to just soak. The water heater will not be supplying the temperature necessary to fill the tub in the same way that an upright heating element would.) An inadequate heating element is the second possible reason for the problem.
Your hot water heater might need to be replaced if you notice several things. If the water temperature is inconsistent, if the heater makes strange noises like rumbling or banging, if the water is rusty or discolored, or if there are visible leaks around the unit, these could be signs that your water heater is failing. If you have no hot water at all, if your energy bills are unusually high, or if your unit is over 10 to 15 years old, these are also major signs that the heater might need replacing. It's definitely better to look into these signs sooner rather than later.
Several indicators can point to a water heater on the fritz. 1. Hot water is gone, or there's inconsistent water temperature. 2. Noises coming from the unit are louder or stranger than normal. 3. Water coming from the unit is rusty or discolored. 4. The unit seems to be leaking or has water pooled around it. 5. The unit is older than ten years or your energy bills have significantly increased.
Your water heater may show several signs of needing replacement. Think first about how old it is. If it's more than 8 years old but less than 12, it may be time for a new one. Next, look for leaks. If you see any significant water pooling at the base of the unit, that indicates tank failure may be imminent. Do you have inconsistent water temperatures? Is there very little or no hot water coming out? Those issues might suggest problems with your heating elements or the thermostat. You can't hear them if they're making noise, but if your heating elements are working inefficiently, they're liable to be making more noise than normal. Or maybe they're working fine and the sediment inside your water tank is making all the noise. Popping and rumbling sounds coming from your water heater could mean damaging amounts of sediment buildup. And a reputable water heater authority says that
If a 7-year-old water heater is working well and shows no serious signs of wear or damage, there's no reason to think it needs replacing. But if you find that it's requiring more repairs than it used to, or if you're noticing some pretty significant changes in its operating "normal," that's a good indicator that you should be planning to replace it soon. Signs like strange noises, leaks, or water temperature that's all over the place can also mean that it's time to start looking for a new water heater. On average, at least according to the manufacturer's suggested ratings, they last anywhere from about 8 to 12 years.
Indeed, a water heater that has reached the age of 20 years is well past its anticipated lifespan. The typical expectation for water heater longevity is 8 to 12 years. After 20 years, even if the contraption seems to be functioning well, it's almost certainly not running with the kind of efficiency one takes for granted in a newer model. And then there's the question of imminent failure, which is always a possibility with an old device. Replacing a 20-year-old water heater with a new model could save a significant amount of money.
Your hot water heater can give you several signs that it's on the verge of going out. One of the most common and telling indicators is a sudden lack of hot water. You might also notice that your water is only coming out at lukewarm temperatures. If this is happening, it could mean that your hot water heater's heating element has gone bad. Then there's the matter of rust. If you start to see rusty or otherwise discolored water coming out of your taps, it could mean that corrosion has set in inside your tank. Short of actually cutting your water tank open, there's no way to know for sure how much corrosion is going on. A telltale noise that you might hear from your water heater is a rumbling or banging sound. A less common, but still possible, scenario is that your water heater is leaking.
Several factors influence this decision, including the type and severity of the problem, the cost of repairs, and the overall condition of the water heater. On average, water heaters last around 8-12 years, meaning a 10-year-old heater is on borrowed time. If the repairs are minor and the unit is still in decent shape, it might be worth it to fix the thing. But if the problems are significant and/or the repairs are costly, it becomes a question of cost-effectiveness and energy efficiency. The next model will almost certainly pay for itself in the long run.
Water heater longevity may depend more on usage and maintenance than brand alone. Still, water heater companies such as Rheem, A.O. Smith, and Bradford White are often named when asserting the reliability of water heater brands. And part of their reputation stems from how long they seem to last. The warranties on the more or less same water heaters also point to the company’s confidence in their product.
Indeed, a water heater's age can influence home insurance. A water heater that is old may present a greater risk of breakdown and leaks, which can result in water damage. The age and condition of a water heater are often taken into account by insurers when they are deciding what kind of coverage to offer and what kind of premiums to charge. And an insurance company does appear to look more favorably upon a home with a newer water heater. So if you have an old water heater, replacing it might not only reduce the risk of a claim but also save you some money on your premiums.
Flushing a water heater once a year is generally recommended in order to remove sediment accumulation and maintain the heater's efficiency.
