Electric water heaters typically last 10 to 15 years, while gas water heaters last 8 to 12 years. Both can be extended several years with proper annual maintenance (flushing, anode rod inspection, T&P valve testing), and shortened by hard water, high pressure, or neglected sediment buildup.

Lifespan factors

  • Water hardness — higher hardness shortens life
  • Static water pressure — above 80 PSI shortens life
  • Annual flushing and anode rod care
  • Quality of original installation
  • Frequency of use

Extend the life of yours with regular water heater maintenance, and consider a water softener if you’re in a hard-water area.
