Hot Water Heater Lifespan

The water heater gets a workout in most homes. The manufacture’s tank warranty is a good guideline to use as far as life expectancy is concerned, but this will vary with the severity of local weather, the unit design, quality of installation, and the level of maintenance your unit has received.

While the typical water heater has a lifespan of about 10 years, careful consideration of the factors that pertain to its lifespan can provide homeowners with information about the potential costs of replacing the water heater. These factors include: correct installation; usage volume; construction quality; and maintenance.

Correct Installation - A water heater should generally be installed upright, in well-ventilated areas, not be placed in an area susceptible to flood damage, and placed in an easily accessible area for maintenance.

Usage - water heater life expectancy depends a great deal on the volume of water used - large quantities of water use means that the water heater works harder while increasing the corrosive effect of the water.

Construction Quality - you get what you pay for in a water heater. According to a 2007 Consumer Report that deconstructed 18 different models of water heaters, it was determined that models with longer warranties invariably were of superior manufacturing quality, with nine- and 12-year models typically having larger or higher-wattage heating elements, as well as thicker insulation. Models with larger heating elements have a much better resistance to mineral buildup or scum. Note: Warranties often exclude labor costs.

Maintenance - periodically flush the water heater system, taking care not to damage the water heater valve, which is usually made of plastic and is easy to break. As the homeowner, you should consider the age and warranty of the model, and carefully weigh the cost-benefit of maintaining an existing heater versus buying a new one.

When looking for a water heater, consider these features:

  • Gallon capacity (40-gallon and 50-gallon heaters are most common)
  • Recovery rate (the number of gallons the heater will heat in an hour)
  • Dimensions (width and height — physical space may limit your ability to upgrade your unit’s capacity — will the heater fit in the space you have for it?)
  • The energy efficiency rating (a sticker on the side should list the estimated annual cost of operation for the unit)
