How Long Should Your Hot Water Heater Last?

 

Quick Answer: 8-12 years for tanked models, 10-15 years for tankless

Long Answer: It depends.

There’s about a dozen variables that determines the amount of operational days left in your water heater.  Let’s break this down:

A water heater is an essential home appliance providing hot water for bathing, cleaning, and other household needs. Like any other appliance or machinery, a hot water heater has a lifespan and will eventually need to be replaced. If you’re wondering how often you should change your water heater, here’s a guide:

Typical Lifespan of a Water Heater

The lifespan of a water heater depends on the type, usage, and maintenance activity. Here’s a general breakdown:

  • Traditional Tank Water Heaters: 8 to 12 years
  • Tankless (On-Demand) Water Heaters: 15 to 20 years

While these numbers provide a range, several factors can influence how long your particular water heater will actually last.

 

Extending The Life Of Your Water Heater

How Long Does a Water Heater Last?

To make the most of what you have right now, follow these maintenance tips:

 

  • Flush the tank annually to remove sediment buildup.
  • Check the anode rod every few years and replace it if it’s corroded.
  • Inspect for leaks and rust periodically.
  • Insulate the heater to improve energy efficiency.
  • Have professional maintenance checks to ensure optimal performance.

Signs Your Need a New Water Heater

Even if your water heater has not yet reached the end of its estimated lifespan, certain warning signs provide an indicator that it’s time for a replacement:

1) Age of Unit

If your water heater is over 10 years old (for a tank model) or 15 years old (for a tankless model), it may be nearing the end of its efficiency. Check the manufacturer’s label on the unit for the installation date.

2) Rusty or Discolored Water

If you notice rusty or brownish water coming from your hot water taps, it may indicate corrosion inside the tank. Rusting can lead to leaks and contamination, showing the need for a replacement.

3) Insufficent Hot Water

 

If your water heater struggles to provide enough hot water or the temperature fluctuates frequently, it might be due to sediment buildup, aging heating elements, or an inefficient system.

4) Leaks Around the Tank

Water pooling around your heater is a clear sign of a leak. While some leaks can be repaired, a corroded tank generally means you’ll need a new water heater.

5) Strange Noises

Loud rumbling, popping, or banging noises indicate sediment buildup in the tank. Over time, this reduces efficiency and can cause damage, necessitating a replacement.

6) Increasing Energy Bills

An old or malfunctioning water heater requires more energy to heat water, leading to higher utility bills. If you notice a steady or steep increase in energy costs, replacing your heater with a more efficient model could be beneficial.

Wrapping It Up

On average, you should consider replacing your traditional water heater every 8-12 years and your tankless water heater every 15-20 years. However, signs such as leaks, rust, noise, and inefficiency can indicate that it’s time for a new unit soon. Proper maintenance can extend the life of your water heater and help you avoid sudden failures. If you suspect your water heater is nearing the end of its life, consulting a professional firm helps you determine the best course of action.
