When January mornings bring cooler desert air, the last thing Phoenix or Scottsdale homeowners want is to step into a freezing shower. Hot water isn’t just about comfort, it’s a necessity for daily routines like bathing, cleaning, and cooking. But as your system ages, you may begin to wonder: how long should a water heater last? And more importantly, what happens when it doesn’t?
How Long Should a Water Heater Last?
On average, a traditional tank style water heater lasts about 10 to 15 years, while tankless models can operate up to 20 years with proper care (Energy.gov). Of course, those numbers can vary depending on the quality of the unit, water hardness, and how well it has been maintained. In Arizona, our mineral rich water often leads to sediment buildup, which can shorten the lifespan of a water heater if regular maintenance isn’t performed.
If you’re asking yourself how long a water heater should last, it’s smart to check the age of your system. If your unit is nearing the end of its expected life, planning for replacement now can save you from cold mornings and unexpected breakdowns later.
What Happens When a Water Heater Fails?
When water heaters start to wear down, the effects go beyond lukewarm showers. Some of the most common issues include:
- Cold Showers: The most obvious sign is inconsistent or no hot water. That quick splash of cold can be especially jarring on a chilly January morning.
- Rumbling or Banging Noises: Sediment buildup at the bottom of the tank can cause your system to overheat and make loud noises as it struggles to keep up.
- Rusty or Discolored Water: Corrosion inside the tank can lead to rusty water at the tap, a sure sign your water heater is nearing the end of its life.
- Leaks Around the Tank: A leaking water heater isn’t just inconvenient; it can also cause water damage to your home if not addressed quickly.
When you’re relying heavily on hot water during the cooler months, these problems can make daily routines frustrating, or even impossible.
Why Winter Usage Strains Water Heaters
While Arizona winters are mild compared to other states, colder nights and mornings increase hot water demand. Families often take longer, hotter showers, run dishwashers more frequently, and use hot water for extra loads of laundry. All of this adds strain to a water heater that may already be nearing the end of its lifespan.
That’s why understanding how long a water heater should last is so important. If your system is aging, pushing it harder in winter can cause it to fail at the worst possible time.
Be Proactive Before It Breaks Down
Replacing a water heater isn’t something most homeowners think about until it stops working, but waiting until it fails can leave you scrambling. If your unit is over 10 years old, showing signs of wear, or struggling to keep up with demand, it’s time to start planning your next step.
