Water heaters typically need to be replaced every 8 to 12 years, depending on the type and maintenance:
- Traditional tank water heaters usually last between 6 and 12 years, with many sources recommending replacement around the 8 to 10-year mark to avoid unexpected failures
- Tankless water heaters have a longer lifespan, often lasting more than 20 years
- Gas water heaters generally last about 8 to 12 years, while electric models may last 10 to 15 years
Replacement is advised when the water heater shows signs such as leaks, rust or corrosion, fluctuating water temperature, strange noises, or decreased efficiency
. Regular maintenance, including annual flushing and anode rod replacement, can extend the life of a water heater but does not eliminate the need for eventual replacement
. In summary, consider replacing your water heater if it is over 8-12 years old or exhibits significant problems affecting performance or safety
