How Long Should a Water Heater Last?

Water heaters are one of those appliances we rarely think about — until they stop working. Understanding their lifespan helps you plan ahead.

Tank Water Heaters

Traditional tank water heaters typically last 8–12 years. The lifespan depends on water quality, usage, and whether annual maintenance (like flushing the tank) has been performed.

Tankless Water Heaters

Tankless units last significantly longer — typically 15–20 years — because they’re not constantly heating and storing water.

Extending the Life of Your Water Heater

Annual flushing to remove sediment, inspecting the anode rod, and addressing leaks promptly can add years to your water heater’s life.

When It’s Time to Replace

If your tank is more than 10 years old and showing signs of rust or leaking, it’s likely time. Call Air & Energy at 941-778-0773.
