Endless Hot Water, Expert Repairs: Tankless Water Heater Services by All Things Mechanical

While highly efficient, tankless water heaters can experience specific issues that require professional attention. Here are some of the common problems we encounter and expertly repair:

• Mineral Buildup (Scaling): This is perhaps the most frequent issue, especially in areas with hard water. Minerals like calcium and magnesium can accumulate inside the heat exchanger, reducing efficiency, causing inconsistent temperatures, and eventually leading to system shutdown or damage. Regular flushing (descaling) is crucial preventative maintenance.
• "Cold Water Sandwich" Effect: This occurs when a brief burst of cold water interrupts hot water flow, often experienced between back-to-back hot water uses. While sometimes inherent to the design, prolonged or severe cold spells can indicate other issues like flow rate problems.
• System Overload: If too many hot water fixtures or appliances are used simultaneously, the unit's flow rate capacity can be exceeded, causing it to struggle to keep up or even shut down.
• Ignition or Flame Failure: Problems with the gas supply, faulty ignition components, or improper ventilation can prevent the unit from igniting or maintaining a flame, resulting in no hot water.
• Inconsistent Water Temperature: Fluctuating water temperatures can be caused by various factors, including mineral buildup, a dirty water filter, or issues with the unit's flow sensor.
• Low Water Pressure: Clogged filters, mineral buildup, or issues with the water supply can lead to reduced hot water pressure.
• Error Codes: Most modern tankless water heaters display error codes to indicate specific malfunctions. Our technicians are trained to interpret these codes and quickly identify the underlying problem.
• Leaks: While less common than with tanked heaters, leaks can occur from connections or internal components, requiring immediate attention.
