How Long Does a Water Heater Last? Signs It’s Time to Replace

What to know about lifespan, warning signs, and when it’s time for a new unit.

As a company that has been servicing Wichita, Kansas homes since 1996, we know exactly how frustrating it can be for homeowners to experience a damaged water heater. It’s not just about missing out on hot water. Ruptured water tanks can release dozens of gallons of water, damaging floors and flooding walls. If left unchecked, it can lead to mold and expensive repairs. That’s why Comfort Systems provides 24/7 emergency services 365 days a year.

As a company that provides in-house financing alongside licensed and bonded technicians and installers, we promise we’ll be there when you need us most. However, as a homeowner, there are several signs it’s time to replace your water heater. So, how long does a hot water heater last? More importantly, what are the signs that it’s time to replace your water heater?

Key Takeaways

1Traditional water heaters typically last 8 to 12 years, while tankless units can last 20 years or more.
2Once a water heater nears the 10-year mark, it’s worth watching closely for early warning signs.
3Not enough hot water, rust-colored water, and rumbling noises can all signal a water heater nearing the end of its life.
4Water pooling around the base of the tank usually means a leak, and it won’t get better on its own.
5Rising energy bills can be a sign your water heater is working harder than it should to keep up.

How Long Does a Water Heater Last?

Comfort Systems supports, services, maintains, and installs both traditional water heaters and tankless water heaters. The average lifespan of a water heater is about 8 to 12 years. Some may last longer, but relying on a water tank past 12 years comes with considerable risk. For tankless water heaters, 20 years or longer is the norm.

For traditional water heaters, sediment buildup in the tank can reduce the efficiency of the unit and shorten its life. However, while sediment buildup is typically a sign of an older water heater, corrosion can become an even greater and more frequent concern as the unit ages.

Water heater maintenance and inspection

Ultimately, it’s important to be aware of the age of your water heater rather than simply waiting for it to fail. By staying mindful of your water heater’s age and taking advantage of our maintenance services, you can avoid the high costs of a sudden and catastrophic failure.

Signs It’s Time to Replace Your Water Heater

There are several signs to pay attention to when assessing the condition of your water heater to avoid a serious failure. First, always be aware of your unit’s age. Once it approaches 10 years old, older water heaters frequently start to develop problems.

Second, if you start to notice that you don’t have enough hot water throughout the day, it could point to an issue with your water heater. As a unit reaches the end of its lifespan, it often encounters issues with its heating components or sediment buildup at the bottom of the tank, negatively impacting performance.

Third, rust or discolored hot water is a clear sign that something is wrong. This typically indicates that corrosion inside the tank is causing a rusty or discolored appearance in the water. Fourth, water pooling in and around the bottom of the tank indicates leaks. Over time, a tank can deteriorate, leading to cracks that allow water to escape.

Other warning signs include strange noises. If you hear rumbling sounds while your water heater is running, it could be caused by hardened sediment at the bottom of the tank. Finally, unexpected spikes in your energy bills serve as another common warning sign.

When combined with a water heater nearing the 8- to 10-year mark, these warning signs strongly suggest that the unit should be replaced.

Nearing 10 Years Old
Age alone is reason to start paying closer attention.
Not Enough Hot Water
Heating components or sediment buildup affecting performance.
Rust or Discolored Water
A sign that corrosion has developed inside the tank.
Water Around the Tank
Deterioration and cracks can let water escape over time.
Rumbling Noises
Often caused by hardened sediment at the bottom of the tank.
Higher Energy Bills
A less efficient unit often means rising costs to run it.
