Water Heater Repair in WaxahachieTankless Water Heater Repair in Waxahachie, TX

What Usually Causes These Problems
Tankless heaters heat water as it flows through a compact heat exchanger. Minerals in hard water coat it over time and reduce flow and efficiency. Venting issues and sensor failures are the other common sources of trouble.
When to Call a Professional
If your unit shows a repeating error code, smells of gas or exhaust, or leaks, stop using it and call. Regular descaling often prevents the most common faults, so do not ignore a drop in flow.
