How Long Do Water Heaters Last?

The lifespan of a water heater depends on factors such as the type of heater, maintenance, and water quality. On average, traditional tank water heaters last 8 to 12 years, while tankless water heaters can last 20 years or more with proper upkeep. Regular flushing of the tank, checking for sediment buildup, and replacing worn-out components can help extend a unit's life.

  • Traditional tank water heaters last 8-12 years
  • Tankless water heaters last 20+ years
  • Regular maintenance extends longevity
  • Water quality and usage affect lifespan

Why Do Water Heaters Fail?

Water heaters fail due to various reasons, including sediment buildup, corrosion, and component wear. Over time, minerals in the water accumulate at the bottom of the tank, reducing efficiency and causing overheating. Additionally, corrosion inside the tank or a failing anode rod can lead to leaks. Other common issues include a faulty thermostat, heating element, or pressure relief valve.

  • Sediment buildup reduces efficiency
  • Corrosion and rust cause leaks
  • Thermostat and heating element failures
  • Lack of maintenance accelerates failure

What Are the Signs You Should Replace Your Water Heater?

Recognizing the warning signs of a failing water heater can prevent unexpected breakdowns. If your water heater is over 10 years old, shows signs of rust, leaks, or provides inconsistent water temperature, it may be time for a replacement. Other red flags include strange noises, rising energy bills, and frequent repairs.
