Understanding Common Noises From Navien Water Heaters

Is your navien water heater making strange noises? Don’t worry, you’re not alone. Understanding the different types of noises your navien water heater may produce can help you diagnose and address potential issues before they become larger problems. In this section, we’ll explore three common noises and what they may indicate.

Banging Or Hammering Sound

  • Loose pipes: Check for loose pipes that may be vibrating against the wall or floor. Tighten or secure the pipes to eliminate the noise.
  • Water hammer: When water flow is suddenly stopped or redirected, it can cause a banging sound. Installing a water hammer arrestor can help reduce this noise.
  • Sediment buildup: Sediment accumulation at the bottom of the tank can cause water to boil and create banging noises. Flushing the water heater annually can help prevent sediment buildup.

Whistling Or Whining Noise

  • Water flow restriction: A whistling or whining noise may be due to restricted water flow. Check the water inlet valve and make sure it is fully open.
  • Venting issues: Improper venting can cause a whistling noise. Ensure that the vents are clear from any obstruction and properly installed.
  • Heat exchanger problems: A damaged heat exchanger can also result in whistling or whining noise. If you suspect this to be the case, it’s best to contact a professional plumber for inspection and repair.

Gurgling Or Popping Noise

  • Air in the system: Gurgling or popping noises may indicate air in the pipes or water heater. Bleed the air from the system by opening the air vents until water flows consistently.
  • Scaling or mineral buildup: Mineral deposits or scaling inside the water heater can create gurgling or popping sounds. Regular maintenance, such as descaling, can help prevent this issue.
  • Backflow: If the water heater is connected to a closed system, a gurgling noise may occur due to backflow. Install a pressure relief valve to eliminate this noise.
