How Long Do Water Heaters Last?

Posted on: June 7, 2016

water heatersIt depends.  Usually water heaters are warranted for five years, ten years or even for life.  A water heater with a five-year warranty should provide 4-6 years of trouble-free service.  A 10-year warranty unit could last 15 to 20 years if properly maintained.

Very few things fail in a water heater.  Since hot water expands, over time this can cause your water heater to leak.  The electrical heating element is usually the only other part of a water heater that needs regular maintenance.

The hardness of the Tampa Bay area water supply corrodes these elements over time.  Telltale signs include a reduction of hot water available and reduced hot water temperatures.

According to HouseLogic, a simple maintenance routine will add years to the life of your home water heater.

  •    Adjust the thermostat to 120 degrees. You’ll save up to 5% in energy costs for every 10 degrees you lower the temperature. You’ll also reduce the risk of scalding.
  •    Drain about a quarter of the tank a few times a year to remove sediment and debris.
  •    Annually test the temperature-pressure relief valve by quickly discharging it two or three times.
  •    Examine the sacrificial anode rod every three years.
  •    Insulate older units with a fiberglass jacket to improve efficiency.
