Tankless Water Heater Installation & Replacement in Atlanta Metro

Tired of Your Tankless Water Heater Failing You?

Is your tankless water heater constantly flashing error codes, or are you getting that dreaded “cold water sandwich” in the middle of your shower? These aren't just minor glitches; they're signs your unit is likely at the end of its life or was never installed correctly in the first place. Head's Plumbing Sales and Service, Inc. has seen it all across Atlanta Metro and is ready to provide a permanent solution.

Warning Signs Your Tankless Unit Needs Replacement

When a tankless water heater starts to fail, it gives you clues. These aren't just annoyances; they're symptoms of a system that's overworked, aging, or improperly matched to your home. Ignoring them often leads to a complete breakdown when you least expect it.

Inconsistent Hot Water

You turn on the shower and get hot water, then a blast of cold, then hot again. This "cold sandwich" effect means the unit can't maintain a consistent temperature, often because of a failing flow sensor or a heat exchanger choked with mineral scale. It’s a clear sign the unit is struggling to meet your home's demand.

Reduced Water Flow and Pressure

If your hot water pressure has noticeably dropped, it's a classic symptom of sediment buildup. Over the years, minerals from our water supply clog the narrow passages inside the heat exchanger. This restriction forces the unit to work harder for worse results and can cause permanent damage.

Loud Banging or Grinding Noises

Your tankless unit should be relatively quiet. If you hear loud banging, popping, or grinding sounds, it’s often due to "kettling"—water boiling against super-heated mineral deposits inside the heat exchanger. This is a sign of severe scaling and puts immense stress on the unit's core components.

Frequent and Recurring Error Codes

A one-off error code might be a simple reset, but if you're constantly seeing codes for ignition failure, flame loss, or overheating, it points to a deeper, systemic problem. These recurring faults indicate that critical internal parts are failing. Constantly paying for repairs on an old unit is often more expensive than a replacement.

Visible Leaks or Corrosion

Any water dripping from your unit or rust forming on the casing is a serious red flag. Leaks can come from failing seals, cracked pipes, or, most critically, a compromised heat exchanger. A leaking heat exchanger is often the final nail in the coffin, as the cost to repair it typically exceeds the value of the unit itself.

Common Causes for Tankless Water Heater Failure

We see the same core issues time and again across the Atlanta Metro area. Understanding why your unit failed helps ensure the new one is installed for maximum longevity and performance. It’s rarely a single event, but rather a combination of factors over time.

Severe Mineral and Sediment Buildup

Atlanta’s water can be hard on plumbing. Without regular flushing and maintenance, minerals build up inside the heat exchanger, forming a rock-like scale. This forces the unit to overheat to do its job, eventually leading to component failure and cracks in the exchanger itself.

End of Operational Lifespan

A quality tankless water heater can last up to 20 years, but only with proper care. Units over 10-15 years old, especially those that have been neglected, will start to experience failures in their electronic boards, gas valves, and sensors. At a certain point, replacing the unit is more practical and cost-effective than chasing down one failing part after another.

Incorrect Sizing or Improper Installation

We frequently replace units that were never right for the home to begin with. An undersized unit will constantly struggle to keep up with a family's hot water demand, leading to premature wear and tear. Likewise, improper gas line sizing or inadequate venting from the original installation can starve the unit of fuel or cause it to overheat, drastically shortening its life.

Heat Exchanger Failure

The heat exchanger is the heart of your tankless water heater. Corrosion from water chemistry or constant stress from overheating due to scale can cause it to crack and leak. This is not a simple repair; a failed heat exchanger almost always means it's time for a full unit replacement.
