7 Signs You Need a Water Heater Replacement

Your water heater works hard every day, providing hot water for showers, dishes, and laundry. But like all appliances, it has a limited lifespan. Knowing when to replace your water heater can save you from cold showers—or worse, a flooded home.

How Long Do Water Heaters Last?

Traditional tank water heaters typically last 8-12 years, while tankless models can last 15-20 years with proper maintenance. If your water heater is approaching or has exceeded its expected lifespan, it's time to start watching for these warning signs.

The 7 Warning Signs

1Age Over 10 Years

Check the serial number on your water heater to find its age. If it's over 10 years old and showing any other symptoms, replacement is likely more cost-effective than repair.

2Rusty or Discolored Water

If hot water from your taps looks rusty or has a metallic taste, it could mean the inside of your tank is corroding. This rust will eventually cause leaks.

3Strange Noises

Rumbling, popping, or banging sounds indicate sediment buildup at the bottom of the tank. This sediment hardens over time and reduces efficiency, eventually causing damage.

4Leaking Around the Base

Water pooling around your water heater is a serious sign. While it could be a valve issue, it often indicates a crack in the tank itself—which means replacement is necessary.

5Inconsistent Water Temperature

If your water temperature fluctuates wildly or you're running out of hot water faster than usual, the heating element may be failing.

6Higher Energy Bills

An aging water heater has to work harder to heat water, which shows up on your utility bills. A new, efficient model could save you 10-20% on water heating costs.

7Frequent Repairs

If you're calling a plumber every few months for water heater issues, those repair costs add up. At some point, replacement becomes the smarter investment.

Tank vs. Tankless: Which Should You Choose?

When replacing your water heater, consider whether a tankless model might be right for you:

Tank Water Heaters

✓ Lower upfront cost
✓ Simple installation
✓ Works during power outages (gas)
✗ Takes up more space
✗ Higher operating costs

Tankless Water Heaters

✓ Endless hot water
✓ Energy efficient
✓ Longer lifespan
✗ Higher upfront cost
✗ May need electrical upgrades

Don't Wait for a Failure

A water heater that fails suddenly can cause significant water damage to your home. If you notice multiple warning signs, schedule an inspection before you're dealing with an emergency.
