Tankless Water Heaters

Common Problems and Solutions With Tankless Water Heaters:

  • Fluctuating Water Temperature:
      • Issue: Inconsistent water temperature can be frustrating, with hot water suddenly turning cold or vice versa.
      • Solution: This problem may occur due to a variety of reasons, including a clogged filter, inadequate gas supply, or scale buildup in the heat exchanger. Cleaning or descaling the unit and ensuring proper gas supply can help resolve this issue.
  • Mineral Buildup and Scaling:
      • Issue: Over time, mineral deposits can accumulate in the heat exchanger, leading to reduced heating efficiency and potential damage to the unit.
      • Solution: Regular maintenance is essential to prevent scaling. Flushing the system with vinegar or a descaling solution can help remove mineral buildup and restore optimal performance. Greer Water Works plumbers offer professional descaling services to ensure thorough cleaning of tankless water heaters.
  • Ignition Failure or Error Codes:
      • Issue: Ignition failure or error codes displayed on the unit indicate underlying issues that require attention.
      • Solution: Check for obstructions in the venting system, ensure proper gas supply and pressure, and inspect ignition components for faults. If the problem persists, it’s best to consult Greer Water Works plumbers to diagnose and repair the issue accurately.
  • Water Pressure Problems:
      • Issue: Low water pressure or inadequate flow can affect the performance of tankless water heaters, leading to insufficient hot water supply.
      • Solution: Check for clogged filters, valves, or pipes that may restrict water flow. Greer Water Works plumbers can assess the system, identify any blockages, and recommend appropriate solutions to restore optimal water pressure.
  • Leakage or Dripping:
    • Issue: Leakage or dripping from the unit indicates potential leaks in the plumbing connections or internal components.
    • Solution: Inspect the unit for visible leaks and tighten any loose connections. If the leakage persists, it may require professional repair or replacement of faulty components. Greer Water Works plumbers can conduct thorough inspections to pinpoint the source of leaks and perform necessary repairs.
