When to Replace a Water Heater

When to Replace a Water Heater

Is your water heater acting up? Whether it’s leaking, making weird noises, or failing to heat properly, you’re probably wondering if it’s time for a repair or a full replacement. Let The Trade Table break it down so you know exactly what to do!

How Long Do Water Heaters Last? 

Tank Water Heaters: 6-12 years (with proper maintenance).

Tankless Water Heaters: 20+ years.

Check your water heater’s warranty—this will give you the best estimate of its expected lifespan.

Signs You Need to Replace Your Water Heater 

🚨 If you notice any of these issues, it may be time for a new unit:

Leaks – If you see moisture or puddles around your heater, replace it immediately before it causes water damage or an explosion risk.
Loud Knocking Noises – This means sediment buildup inside the tank. If flushing the tank doesn’t fix it, replacement may be needed.
Rusty or Cloudy Water – Discolored water with a metallic odor could indicate corrosion inside the tank—a major sign it’s failing.
Inconsistent Water Temperature – If hot water runs out too fast or stays cold even when the tap is on hot, your heating elements may be failing.
Higher Energy Bills – An inefficient water heater works harder and uses more energy, which can increase your bills.

Can You Repair Your Water Heater Instead? 

Before replacing, check if a simple repair can do the trick! You might just need to replace a part, such as:

🔧 Burner assembly
🔧 Heating elements
🔧 Thermostats
🔧 Valves
🔧 Thermocouples
🔧 Igniters & motors

Repair if: The unit is under 10 years old and the issue is isolated to one part.

Replace if: The unit is over 10 years old, leaking, or showing multiple problems.

How to Make Your Water Heater Last Longer 

Want to avoid premature replacement? Regular maintenance is key! 

Flush the tank at least once a year (every 6 months in hard water areas).
Inspect & replace the anode rod if it’s corroding.
Check pressure relief valves to prevent dangerous buildup.
For tankless heaters, flush the system annually to remove lime and mineral deposits.

Time to Replace Your Water Heater?

If your water heater is over 10 years old and showing signs of failure, it’s time to replace it. A new water heater will be more efficient, save you money on bills, and keep your home running smoothly.
