Tankless Water Heater Repair

Amarillo’s municipal and well water often has lots of mineral buildup, including dissolved calcium and magnesium. Tankless water heaters are a great option for many homes in the area; however, high water hardness can sometimes cause problems.

The water across the area is classified as “very hard”, which can affect your tankless water heater’s functionality. Our local team understands these needs, allowing us to inspect your unit and know exactly what to look for with geographical conditions in mind. In addition to mineral buildup in the water, high total dissolved solids, chloramines & municipal disinfectants, and alkaline conditions can also impact your tankless water heater.

Signs Your Tankless Water Heater Needs Repair

Unlike traditional water heaters, tankless water heaters rarely fail without warning. Most issues associated with tankless water heaters show early warning signs. If you notice any of these early warning signs, call Mr. Rooter today:

  • Fluctuating water temperatures (the shower starts warm, then the water turns ice cold after about thirty seconds)
  • Sudden changes in water pressure
  • Rumbling, clicking, or strange noises
  • Flashing error codes on the digital panel of your tankless water heater

frequently asked questions

Why does my shower start out warm, turn ice cold, and then get hot again?
This phenomenon is known as the “cold-water sandwich.” It occurs when a tankless unit shuts off briefly between uses (such as when someone turns off the faucet and then turns it back on). The system must re-fire its burners and heat the heat exchanger, leaving a brief pocket of unheated water trapped in your supply lines. Modern high-efficiency tankless units or small recirculation buffers help eliminate this temperature drop.
Due to the “very hard” water in Amarillo, which contains high levels of calcium and magnesium, tankless units should be professionally flushed with a descaling solution at least once every 12 months. Hard minerals quickly bake onto the compact copper or stainless steel heat exchanger tubes, restricting flow, reducing thermal efficiency, and triggering system overheat error codes if neglected.
Not always. Tankless water heaters require a high volume of gas on demand—often up to 199,000 BTUs compared to roughly 40,000 BTUs for a standard tank unit. During our initial evaluation, our technicians assess your home’s existing gas meter, gas supply pipe diameter, and venting path to ensure your line can handle the instant load required by a tankless system.
Digital tankless units feature built-in diagnostics that flash specific error codes when a fault is detected (such as flame failure, air intake restriction, or heat exchanger overheating due to mineral scale). Instead of guessing, calling a professional with your unit’s brand and error code allows us to quickly diagnose the exact sensor or component issue.
