Taking cold showers is something that nobody enjoys, especially when the weather is chilly. However, many homeowners tend to neglect the upkeep of their water heaters, which leads to questions such as “When can I expect my water heater to fail?” and “What are the warning signs that my water heater is on its last legs?”
The lifespan of a water heater can vary greatly, depending on the type of heater and how well it is maintained.
How long do hot water heaters last on average?
Determining the longevity of your water heater tank and when to replace it requires understanding multiple factors. One of the key signs that a water heater may need to be replaced is if the water appears discolored, if it’s not producing enough hot water or if it’s making clanking noise.
Generally, with proper care and maintenance, a new water heater can last up to an average of 12 years. However, the lifespan of a water heater can be influenced by various other factors, like
- Tank water heater vs. tankless water heater
- Quality of water in your area (hard water can shorten the lifespan by a few years)
- Frequency of use
- Location of the unit (if it’s in a poorly ventilated area like crawl space or basement, it can take longer to heat up)
The type of water heater you have can also play a part in determining its longevity. Tank water heaters typically last between 8-12 years, while tankless water heaters can last as long as 20 years. Also, the fuel type used in the water heater can impact its lifespan, generally gas water heaters (i.e., gas burner) can last 8-12 years, while electric water heaters have an average lifespan of 10-15 years.
To extend the life of your water heater, it’s important to carry out regular maintenance and service checks, including flushing the tank, inspecting the temperature and pressure relief valve, and checking for leaks.
What are the signs your water heater needs to be replaced?
You hot water heater can give you several signs that it is time for replacement. If your water heater is over 10 years old and you are experiencing any of the following issues, it may be nearing the end of its lifespan.
Lack of hot water
One of the most common signs of a failing water heater is a lack of hot water. If you find that your faucets or shower are not providing sufficient hot water, it may be a sign of sediment or mineral buildup in the unit.
Another indication of an aging water heater is inconsistent heating. If you notice that hot water runs out quickly or does not stay hot for long, it may be a sign that your water heater is no longer able to function properly.
Build up of sediment
Sediment buildup can also occur in older water heaters, which can affect the heating elements and reduce the amount of space inside the tank for water. This can cause the water heater to make creaking and rumbling noises during use.
If you are experiencing these issues, it may be beneficial to call a repair person to clean out the sediment and flush the system. However, if your water heater is older and experiencing these issues, it may be best to consider a replacement to ensure your hot water needs are met.
Degradation from lack of care
Another prevalent problem, particularly in tanks that haven’t received proper care, is general wear and tear. If you notice your water heater leaking or making loud banging noises, it’s a good indication that it is no longer functioning properly. Additionally, when rusty water comes out of your faucets, and your tank is over 10 years old, it’s time to consider a new water heater.
Repairs for water heaters can be expensive, and often multiple parts need to be replaced. Therefore, if you find yourself making multiple repairs on it, it’s more cost-effective to replace the water heater and ensure you take the necessary steps to properly maintain it to extend its lifespan.
Additional indicators of a water heater in need of replacement
Besides the warning signs mentioned above, there are other indicators that your water heater may need to be replaced. If you observe any of the following, it’s best to contact a professional plumber immediately:
- Puddles of water surrounding the base of the water heater (i.e., leaking water heater)
- Accumulation of limescale on the surfaces of your plumbing fixtures
- Discoloration of water to red or yellow color
- Foul smelling or bad-tasting hot water
- Lukewarm or cold water
These are signs that something is amiss with your water heater and might need attention, or need replacement. They might indicate that there is internal damage or other problems that can’t be resolved by simple repairs and need immediate attention.
Anticipating your water heater replacement
By considering factors such as lifespan, location, usage and the quality of the water in your area, you can make an educated estimate about how long your hot water heater will last. Many experts recommend replacing your hot water heater before it reaches the end of its expected lifespan.
One strategy to consider is to plan ahead and replace your water heater two years prior to its expected end of life. For example, if you have a tank-style water heater that is 8-10 years old, it’s a good idea to begin planning for a replacement. Similarly, for a tankless water heater, it’s advisable to start planning for a replacement when it reaches 15-18 years of age.
By taking the time to plan ahead, you can avoid unexpected expenses and budget for a new water heater. Additionally, you won’t have to be without hot water while you wait for repairs or replacement. Furthermore, you can take the time to research your options and pick a water heater that best meets all of your needs.
Take advantage of improved technology
As new models are developed over time, it’s likely that your 10-year-old water heater has been less energy efficient than newer models for quite some time. This means that your water heater may not meet current energy requirements or that you may be spending more on utility bills than you need to.
When you upgrade to a newer model water heater, you will see a reduction in your utility bills right away due to the technological advancements that have been made in recent years. You can learn more about how efficient water heaters should be and how a new one can save you money.
Investigate your warranty options
It’s always worth checking with the manufacturer to see if your water heater is still under warranty. If your water heater is only a few years old and there is an issue, it may be covered by warranty and you could save money by getting it repaired.
Before you invest in a new water heater, reach out to the manufacturer to find out if there are any additional warranty options available that could extend the life of your current water heater.
Selecting the best brand of water heaters
When it comes to purchasing a water heater, you want to invest in a quality product that will last for years to come. With so many different brands and types of water heaters on the market, it can be difficult to know where to start. One way to narrow down your options is by researching the different types of water heaters available, such as tank, tankless, storage, and solar.
In addition to considering the type of water heater, you should also look at other factors such as price, customer service, and reliability when choosing a brand. Some of the most reputable and popular water heater brands include:
- Bradford White
- A.O. Smith
- Rheem
- Westinghouse
- GE
- Whirlpool
- Kenmore
These brands are well-known and have a history of providing high-quality appliances. For a brand that specializes in a specific line of products related to water heaters, filters, and other plumbing fixtures, A.O. Smith, Bradford White, and Rheem may be your best bet. In fact, when looking at lists of the top 10 best water heaters, you will likely see these brands mentioned.
It’s worth noting that professional plumbers usually recommend brands like Bradford White as they are higher quality than water heaters mass-produced for big-box retail stores. To avoid the inconvenience of a sudden cold shower and ensure you have a water heater that works effectively, it’s best to consult with a professional plumber for recommendation.
