Age
Most traditional tank water heaters last 8–12 years, while tankless models can last 15–20 years with proper maintenance. If your unit is nearing the end of its lifespan, it may become inefficient or fail unexpectedly. Upgrading before a complete breakdown can save you from inconvenient and costly emergencies.
Inconsistent Water Temperature
Does your water alternate between hot and cold unexpectedly? If your water heater isn’t maintaining a steady temperature, the cause could be:
- A failing heating element (for electric models)
- Sediment buildup in the tank
- A malfunctioning thermostat
If flushing the tank or replacing a part doesn’t fix the problem, you may need a new unit.
Strange Noises
Loud banging, popping, or rumbling sounds from your water heater aren’t normal. These noises are usually caused by sediment buildup, which forces the heating element to work harder and less efficiently. Replacing the system might be the best option if you’ve tried other maintenance methods that have failed to address the problem.
Water Leaks
Visible leaks around the base of your water heater are a clear sign of tank damage. Even if you don’t see a direct leak, moisture, rust, or puddles around the unit could indicate a slow failure.
Leaks in the tank itself mean the unit must be replaced–it cannot be repaired.
Discolored or Smelly Water
If rusty, brown, or foul-smelling water is coming from your taps, your water heater may be corroding from the inside or experiencing bacteria buildup. These issues can pose health risks and shouldn’t be ignored. Installing a new system is the easiest and best solution to ensure clean, safe, and reliable hot water.
