How Long Do Water Heaters Last?

It’s important to note, however, that several factors including maintenance, water quality, and usage will affect these expected lifespans.

Factors that impact water heater longevity

We’ve already mentioned that tankless models generally outlast tank-style water heaters since these units don’t store water and are less prone to issues like rust or sediment buildup, but each is influenced by other factors that affect longevity as well. Here are some common considerations:

• Maintenance Routine: Perhaps the most important is maintenance timeliness. For tank-style units, flushing the tank annually to remove sediment buildup and checking the anode rod (and replacing if necessary) can keep the unit in top shape. Tankless models require descaling to prevent mineral buildup in the heating elements.
• Water Quality: The hardness or softness of your water plays a significant role. Hard water contains high levels of minerals like calcium and magnesium, which can lead to sediment buildup in tank-style water heaters. Over time, this sediment can corrode the tank and reduce efficiency.
• Quality and Brand: To no surprise, higher-quality water heaters from reputable brands often come with better materials, advanced technology, and longer warranties which promise a longer lifespan.
• Usage Levels: Water heaters in larger households or businesses that use hot water frequently may experience more wear and tear.

Signs it’s time to replace your water heater

A water heater replacement is inevitable, but when is it time to pick up the phone and call Mr. Rooter Plumbing? Typically, we recommend a replacement when the cost of repairs approaches half the cost of a new unit. It’s also wise to upgrade when the life expectancy is fulfilled as old water heaters tend to be inefficient and waste energy.

Moreover, severe corrosion and leaks at the base of the tank also warrant a replacement. Rust-colored hot water could indicate that the tank is corroding from the inside.
