Real-Life Case: A Heater That Kept Shutting Off

A local homeowner in Knoxville reached out when their on-demand water heater would suddenly go cold and only work after flipping the breaker back on. The unit was only a few years old and had never been flushed, so they called HEP for expert help. After an initial review, our HEP technician determined that mineral deposits and debris were most likely causing the repeated shutdowns.

How the Issue Was Solved

The HEP technician carefully isolated the unit and circulated a cleaning solution to break up scale inside the heat exchanger. Once the build-up was removed and fresh water ran clear, the system was reassembled and tested. The result? Steady hot water without tripping the breaker. Before leaving, our technician also advised the homeowner on installing a filtration system to soften incoming water and reduce future maintenance.

Why Flushing Matters

Scale from hard water can accumulate quickly in tankless heaters, leading to inefficiency and unexpected shutdowns. By scheduling a professional flush roughly once a year, you clear out those deposits before they become a problem. Adding a whole-home filter can also extend the life of your system, saving you time and hassle down the road.

Tip: Keep Service Areas Accessible

Clear away storage boxes, cleaning supplies, or any items stacked near your water heater. A tidy utility space gives HEP technicians room to work and helps ensure quick, safe service whenever you need it.

General Plumbing Tips for Homeowners

• Inspect for leaks regularly: Even small drips can signal hidden scale or corrosion.
• Check exterior vents: Make sure vent caps are free of debris or bird nests.
• Label your breakers: A clearly marked circuit for your water heater speeds up safe shut-offs.
• Schedule routine inspections: Professional check-ups catch minor issues before they turn into major repairs.

By combining regular maintenance with a few simple checks, you’ll keep your tankless water heater—and the rest of your home plumbing—running smoothly. When you need reliable Plumbing in Knoxville, trust HEP’s skilled technicians to get the job done right.
