How Long Should a Water Heater Last?

One of the most common questions we hear from Bradenton homeowners is: “how long should my water heater last?” The answer depends on the type of water heater and how well it’s been maintained.

Tank Water Heaters

Traditional tank water heaters typically last 8-12 years. With annual maintenance (flushing sediment, checking the anode rod), some last up to 15 years. Florida’s water quality can affect longevity — hard water accelerates corrosion inside the tank.

Tankless Water Heaters

Tankless water heaters have a significantly longer lifespan — typically 15-20 years or more. They’re more energy efficient and, with proper maintenance, can outlast two or three tank water heaters.

Signs Your Water Heater Is Aging Out

Watch for rusty or discolored hot water, inconsistent temperatures, unusual noises, or visible corrosion around the unit. These are signs that replacement may be near.

Don’t Wait for a Failure

A failing water heater doesn’t always give much warning. If your unit is approaching the end of its expected lifespan, plan ahead. Contact Air & Energy at 941-778-0773 to discuss water heater replacement options in Bradenton.
