Diagnosing Common Tankless Water Heater Issues

At TR Plumbing, we understand that your tankless water heater is crucial for maintaining a steady supply of hot water in your home. When issues arise, it's essential to address them promptly to prevent further complications. Tankless water heaters, while efficient, can experience a range of problems, from inconsistent water temperatures to complete failures. Our approach focuses on identifying and resolving these issues effectively.

One common problem is sediment buildup, which can impair the heater's efficiency and lead to overheating. Regular maintenance can mitigate this risk, but if your unit is already showing signs of trouble, it's time to call in professionals. At TR Plumbing, located in Newport News, we specialize in diagnosing these issues using advanced tools and techniques. Our technicians will carefully assess your system, ensuring we pinpoint the root cause before recommending the most effective solution.

Essential Maintenance Tips for Tankless Water Heaters

Maintaining your tankless water heater is vital to ensuring its longevity and efficiency. Regular upkeep not only prevents unexpected breakdowns but also enhances the performance of your system. Here are some key tips to keep your heater running smoothly:


  • Descale Regularly: Over time, mineral deposits can accumulate in your heater. Regular descaling can prevent this buildup and maintain optimal performance.
  • Check the Filter: The inlet filter should be cleaned periodically to prevent clogs and ensure proper water flow.
  • Inspect the Venting: Proper venting is crucial for gas-powered units. Regular inspections can help identify any blockages or leaks that could affect performance.
  • Test Safety Features: Ensure that safety features like pressure relief valves are functioning correctly to prevent accidents.
