When should I replace my water heater?

You should replace your water heater when it’s old, unreliable, or showing signs of wear such as leaks, rust, rising energy bills, or water that never gets hot enough. Most water heaters last 7–10 years, so if yours is approaching that age range, it’s smart to watch closely for symptoms that it’s failing.

Common Causes of Water Heater Problems

Water heaters fail for several reasons, many of which worsen over time:

• Sediment buildup: Minerals, rust, and debris settle at the bottom of the tank, causing overheating, burned-out heating elements, and wasted energy.
• Improper installation: Only a qualified plumber can confirm whether your heater was installed to code and vented safely.
• External leaks: Water leaking onto the exterior of the tank causes rust from the outside in and can damage electrical components, posing shock hazards.

Is Your Water Heater Worn Out?

Even with great maintenance, every water heater eventually needs replacement. Here are the top signs:

• Frequent repairs: Occasional service is normal, but if you’re calling a plumber several times a year, replacement is usually the more economical choice.
• High energy bills: If your usage hasn’t changed but your bills keep climbing, an aging water heater may be losing efficiency.
• Water isn’t hot enough: Sediment buildup inside the tank can insulate the water from the burner or heating element, making it hard or impossible to heat properly.
• Rusty water: Red or brown water from your faucets often means the tank is corroding from within—one of the clearest signs it’s time for a replacement.
