How Long Do Hot Water Heaters Last?

Hot water heaters typically last between 7–20 years or longer, depending on what type of water heating system you have.

  • Standard water heater systems have a life expectancy of 7–10 years, perhaps even 12 years or more with regular maintenance.
  • Tankless/On-demand water heater systems can last 15–20 years or more, may save $100/year or more in energy consumption, and pay for themselves within 10 years due to the energy savings.

Do You Need a Hot Water Heater Replacement?

Are your showers turning cold far too quickly for your liking? Is this a sign that you need a water heater replacement? It just might be, but how can you tell? There are several other reasons you may want or need to look into and schedule a new hot water heater installation.

In addition to age, some more common reasons you should watch for and that indicate a replacement is needed are:

  • Leaks
  • Improper installation
  • Erratic functioning (sometimes it works, sometimes it doesn’t)
  • Rumbling/rattling noises
  • Tinted water or rust (visible on parts and pipes)
  • Want/need to cut energy costs
  • Desire for an upgrade

What Should I Consider When Planning a Water Heater Installation?

Now that you have determined the age and/or the reason you need a hot water heater replacement, your next step is to determine what type of system is best for your home.

You should consider the following in your decision to replace a water heater:

  • Size: For example, standard systems can hold 20-80 gallons of water.
  • Fuel type and availability (natural gas, propane, fuel oil, electricity)
  • Energy efficiency:
    • Standby heat loss is the energy wasted heating water not being used in standard hot water heaters.
    • Gas tankless water heaters have higher flow rates, but choosing between a standing pilot light (uses more gas) and an intermittent ignition device (works more like gas stove ranges and ovens) is a key factor in your decision and your budget.
  • Costs (purchasing, operating, savings)
  • Code/laws for gas or electric water heater installation
