Water heaters perfectly embody “out of sight, out of mind.” Since they’re often stored in the corner of basements and garages, it is easy for people to forget about them and assume they’re working just fine as long as there is running hot water. But this couldn’t be farther from the truth: water heaters start deteriorating over time, and eventually, you’ll need a water heater replacement.

Sometimes, you start running out of hot water and assume your water heater must have failed suddenly. However, water heaters usually give early signs that something is wrong and may need replacement. It’s just that, due to a lack of knowledge, you don’t recognize the signs unless they’re notorious, like rusty water or water turning cold mid-shower, and fail to schedule a water heater maintenance on time.

Hence, if you’d like to expand your knowledge of water heaters to preserve their lifespan and know when to get a well-deserved water system replacement, stay until the end!

How long should your water heater last?

On average, heaters with a storage tank should last 6 to 12 years before needing a water heater replacement. In contrast, a tankless water heater can last for over 20 years. However, the lifespan of your heater depends on several factors, such as its model and how often you get it serviced. Hence, you can usually find more accurate timelines within your water heater’s warranty.

How often should you replace your water heater?

Most water heaters should be replaced after 10 years, as daily wear and tear can deteriorate their safety, performance, and energy efficiency. If you don’t remember how long ago you bought yours, look for the label with the serial and brand numbers, which often also contain the manufacturing date.

Also, remember that this recommended timeline can vary depending on how frequently you get water heater maintenance to catch minor issues, such as corroded sacrificial anodes before they damage your heater. Thus, you may need a water heater replacement 6 years later or 6 months after installation.

Signs you may need a water heater replacement

Several signs can indicate you may need to replace your water heater, so be on the lookout for:

Leaks: Noticing water puddles around your water heater or water dripping from any joints, seams, and seals is a warning sign that your heater isn’t functioning properly. Leaks are usually caused by pressure building up and can lead to an explosion if ignored for too long.

A water heater inspection can help you determine if the build-up pressure is due to excessive pressure, water temperature, or a malfunctioning relief valve and whether or not you can repair it or if it’s better to replace it.

Rusty water and visible corrosion: Corroded water or water with an unfamiliar odor often signs that your unit is underperforming, and you’ll likely need to look for water heater replacement services.

Sometimes, this corrosion is caused by the sacrificial anode rusting and needing to be replaced, but other times, it happens because the tank is starting to rust, often on the steel lining. If the issue is the tank, you should replace it as soon as possible.

Knocking or rumbling noises: If you notice strange noises coming from your water heater, such as rumbling, vibrations, or banging, you may need a hot water system replacement. These noises are often caused by sediment build-up in your tank that moves around and knocks against the walls.
