Tankless water heaters are known for their energy efficiency, space-saving design, and on-demand hot water. But like any appliance, they can run into problems over time. Whether your unit needs routine maintenance, a hard-water flush, or urgent repair, Matthew & Sons Plumbing is here to help. As a Licensed Responsible Master Plumber (RMP #45952) proudly serving McKinney, Frisco, Prosper, and across Collin County, our family-owned team brings expert troubleshooting and honest, transparent pricing to every North Texas home.
Common Tankless Water Heater Issues
Even high-quality tankless systems can develop issues, especially if they haven’t been serviced regularly. Some common problems include:
-
Mineral buildup or scaling
-
Error codes on the display
-
Water that’s too hot—or not hot enough
-
Ignition or burner issues
-
Inconsistent water temperature
If you're experiencing any of these problems, our licensed plumbers can quickly diagnose the issue and recommend the right fix.

Routine Maintenance Save Money
Regular service keeps your tankless water heater running smoothly and extends its lifespan.
