Is Your Tankless Water Heater Acting Up? Common Issues We Resolve:

Tankless water heaters are complex systems, and various issues can lead to a loss of hot water or decreased performance. Our technicians are adept at diagnosing and resolving a wide range of problems, restoring your unit's efficiency and reliability.

No Hot Water / Inconsistent Temperature:

  • Cause: This is often due to mineral buildup (scaling) restricting water flow, a faulty flow sensor not detecting water demand, or issues with the gas supply or igniter. Over time, hard water deposits can accumulate inside the heat exchanger, preventing efficient heat transfer.
  • Our Solution: Our service involves thorough descaling procedures to remove mineral buildup, inspection and replacement of faulty flow sensors, and comprehensive checks of gas lines and ignition components to ensure proper operation.

Error Codes Displayed:

  • Cause: Modern tankless units display error codes to indicate specific malfunctions, ranging from a clogged vent to a component failure like a fan or circuit board. Each code points to a particular system issue requiring expert interpretation.
  • Our Solution: Our technicians are trained to interpret all common error codes from various manufacturers. We precisely diagnose the underlying cause, whether it's a blocked exhaust, a malfunctioning sensor, or a circuit board issue, and perform the necessary repair or part replacement.

Strange Noises (Banging, Hissing, Rattling):

  • Cause: Noises often signal mineral accumulation ("kettling" sounds from boiling water in sediment), air trapped in the lines, or a failing component like the heat exchanger. Hissing might indicate a minor leak or issues with the pressure relief valve.
  • Our Solution: We perform descaling to eliminate sediment, purge air from the system, and inspect all components for wear or damage. Addressing these issues not only quiets your unit but also prevents more significant problems.

Reduced Water Flow/Pressure:

  • Cause: This can be caused by clogged inlet filters, mineral deposits restricting internal pipes, or issues with your home's overall water pressure or the unit's internal pressure regulators.
  • Our Solution: Our service includes cleaning or replacing clogged filters, descaling internal components, and checking water pressure settings to ensure optimal flow and performance from your tankless unit.

Leaking Tankless Unit:

  • Cause: Leaks can result from loose connections, a failing pressure relief valve, or cracks in the heat exchanger, often caused by freezing or excessive pressure.
  • Our Solution: We meticulously inspect the unit to pinpoint the source of the leak, tighten connections, replace faulty valves, or address any damage to components, preventing water damage and restoring integrity.

Tankless Water Heater Repair vs. Replacement: We Guide You

One of the most common questions homeowners ask is whether to repair their existing tankless unit or opt for a replacement. Our experts provide honest, data-driven recommendations tailored to your specific situation in Oakley.

Consider the following factors:

  • Age of the Unit: Tankless water heaters typically last 15-20 years. If your unit is approaching the end of its lifespan and facing a significant repair, replacement might offer better long-term value.
  • Cost of Repair: If the repair cost approaches or exceeds 50% of the cost of a new unit, investing in a new, more efficient model might be a more economical choice.
  • Frequency of Breakdowns: Consistent issues often indicate underlying problems. Multiple repairs within a short period suggest a replacement could be more beneficial for consistent hot water and peace of mind.
  • Energy Efficiency Goals: Newer tankless models often boast higher energy efficiency ratings, which could lead to significant savings on utility bills over time. If your goal is to reduce energy consumption, replacement may align better with your objectives.

We will provide a comprehensive assessment, outlining both repair and replacement options, along with their respective benefits and costs, allowing you to make an informed decision for your home. You can also explore available Financing options to support your investment.

Maintain Your Investment: Preventative Care

While our focus here is on repair, understanding the importance of regular maintenance can significantly extend the life of your tankless water heater and help prevent future breakdowns. Annual flushing and descaling are crucial for removing mineral buildup, which is a primary cause of tankless issues in areas with hard water, like parts of Oakley. Considering a Maintenance Agreement can ensure your unit receives the regular care it needs, safeguarding its efficiency and longevity.
