Very often, when problems occur, they are related to either lack of maintenance, or improper installation.

Tankless water heater service problems include:

  • Installation Issues:
    • Gas fired tankless systems can have very high firing rates. As a result it is critical that their gas supply line and pressure regulator be properly sized. In sufficient gas supply will result in intermittent failures and inconsistent operation.
    • Most tankless water heaters in the Knox, IN area are interior models, and require a properly designed intake air and venting system. An improperly supported vent, a vent utilizing improper materials, or one that is improperly sized can cause condensate accumulation, vent freeze-ups, or intermittent failures.
    • Older facets installed in many applications combined with water pressure fluctuations can cause random changes in the outlet water temperatures at a point of use. Proper sizing of hot water lines and the use of pressure to balance faucets, shower, and tub valves is a must.
  • Maintenance Issues:
    • Some areas in northwestern Indiana can have water quality challenges that require the scheduled maintenance of tankless water heaters to ensure consistent performance. Hard water and other chemical issues that are ignored can result in premature tankless water heater failures. Almost all tankless water heaters have inline screen water filters that can become restricted over time without periodic cleaning.
