Common Problems with Tankless Water Heaters
Tankless water heaters are efficient but not immune to problems that might leave you without hot water when you need it most. These issues, from inconsistent performance to certain system errors, often require professional attention.
Inconsistent Hot Water Supply
One of the most frequent complaints is uneven temperatures or no hot water. This can be caused by:
- Sediment Buildup: Over time, minerals from hard water can collect inside the unit, clogging the heating elements or pipes and reducing efficiency.
- Scaling: If your home has hard water, calcium, and lime deposits can coat critical components, leading to fluctuating temperatures or cold water.
Routine descaling and flushing are typically needed to address buildup and prevent further damage. Ignoring them can shorten your unit’s lifespan.
Low Water Temperature
Does your tankless water heater produce lukewarm water instead of hot? This could stem from:
- System Overload: The unit may not keep up when multiple devices demand hot water simultaneously. For example, running the dishwasher and shower simultaneously can strain an undersized system for your home.
- Malfunctioning Heating Elements: The heating components may have worn out or become damaged over time.
If you frequently experience lukewarm water, it may be time to upgrade to a larger unit or call a technician to inspect the heater.
System Error Codes
Modern tankless water heaters have error codes to signal when something’s wrong. Some common ones include:
- “Error Code 11” Often indicates ignition failure. This might be related to gas supply or venting issues.
- “Error Code 16” is an overheating warning. It usually occurs if water flow is restricted or the unit is not descaled regularly.
- “Error Code 29”: A faulty heat exchanger can trigger this, often caused by scaling or sediment clogging.
While some codes might seem easy to decipher, they often point to underlying issues that require professional diagnostics and repair. Attempting DIY fixes without proper expertise risks causing bigger problems. Keeping an eye on these potential problems can help you avoid major disruptions. However, expert help from Certified Plumbing of Brevard is often the safest course of action with tankless water heater repair.

Without the right approach, you might only fix a symptom while ignoring a bigger issue lurking beneath. A professional diagnosis by Certified Plumbing of Brevard saves time and prevents small problems from becoming costly repairs.
Safety Considerations
Tankless water heaters operate with gas, electricity, and water—which can pose safety risks if handled improperly. Attempting DIY repairs could lead to:
- Gas leaks increase the risk of fire or carbon monoxide poisoning.

Here’s why hiring Certified Plumbing of Brevard protects your investment:
- Ensures repairs align with manufacturer and warranty guidelines.
- Records proper service documentation for claims.

Considering the cost of replacing a tankless water heater, preserving your warranty is a smart and economical decision. A professional repair not only fixes the problem but also safeguards your long-term financial investment.
Choosing professional tankless water heater repair eliminates guesswork, enhances safety, and keeps your system efficient for years. As tempting as a DIY fix might be, leaving it to the experts ensures the best results without unnecessary risk.
Cost of Tankless Water Heater Repair
When your tankless water heater stops working, one of the first questions you might have is, “How much will this cost me?” Repair prices vary greatly based on several factors, but knowing what to expect can help you budget and avoid surprises. Here’s a breakdown of the key considerations.
Factors Influencing Repair Costs
The cost of repairing a tankless water heater depends on several variables. Understanding these factors can give you a clearer idea of what to anticipate:
- Brand and Model: High-end brands or models with advanced features often have pricier components, which can increase repair costs.
- Age of the Unit: Older units may require harder-to-find parts, leading to more expensive repairs. Plus, wear and tear over time can make them more prone to issues.
- Type of Problem: Some issues, like flushing out mineral buildup, are relatively simple and inexpensive. More complex problems, such as replacing a heat exchanger, will cost significantly more.
- Labor Costs in Your Area: Rates for professional technicians can vary depending on location. Urban areas or regions with a high cost of living will often have higher labor charges.
- Gas vs. Electric Units: Gas-powered systems cost more to fix than electric ones due to the complexities of venting and gas supply components.
Asking the technician for a detailed estimate before starting repairs will help you understand how these factors affect your final bill.
Typical Repair Prices
Tankless water heater repair costs usually fall within a wide range, so it’s good to know common price points for various fixes. Here’s a general rundown:
- Descaling or Flushing: If mineral buildup is reducing water flow or causing inconsistent temperatures, expect to pay between $100 and $200 for a professional flush.
- Ignition System Repairs: The cost of fixing ignition issues, often caused by gas supply problems or faulty sensors, can range from $150 to $500.
- Replacing Heating Elements: Depending on the model, worn-out or malfunctioning heating components may cost around $200 to $600.
- Fixing a Leaking Unit: Addressing leaks may require part replacements and labor, typically costing $300 to $700.
- Heat Exchanger Replacement: One of the costliest repairs, replacing a heat exchanger can range from $600 to $1,300. Therefore, it is essential to consider whether repair or replacement is the smarter option for older units.
For minor problems, you might spend under $200. However, larger issues could push repair costs into the $1,000 range. Most homeowners spend $350 to $600 on professional tankless water heater repairs.
Recognizing the type of problem and understanding influencing factors helps you better plan for professional repairs. Regular maintenance can reduce overall repair frequency and extend the life of your system.

When to Call Certified Plumbing of Brevard for Repair
Despite their efficiency and reliability, tankless water heaters may encounter issues beyond basic troubleshooting. Knowing when to call Certified Plumbing of Brevard can prevent minor problems from escalating into costly repairs. Let’s explore two common signs that indicate it’s time to seek expert help.
Unusual Noises
Tankless water heaters are typically quiet during operation. If you hear strange sounds, it’s a red flag that something’s wrong. Some common noises and their potential causes include:
- Knocking or Banging: This can indicate mineral buildup or issues with the water flow. Hard water deposits in your system can create blockages, disrupting normal operation.
- Rattling or Vibrations: Loose components like pipes or brackets can lead to excess noise. An experienced technician might be required to tighten or secure parts safely.
- Hissing or Whistling: Air trapped in the system or a potential gas leak could be the culprit. Certified Plumbing of Brevard should immediately inspect this, as gas leaks can pose a safety hazard.
These sounds should never be ignored. Attempting to fix them without the required tools or expertise could lead to further damage or even safety risks.
Fluctuating Water Pressure
Inconsistent water pressure is more than an inconvenience; it’s a sign of potential system issues that need attention. Here’s why fluctuating water pressure occurs and what Certified Plumbing of Brevard’s professionals might find upon inspection:
- Clogged Filters: Tankless water heaters have filters that can become clogged with sediment or debris over time, reducing water flow.
- Mineral Buildup: Hard water is notorious for forming deposits restricting water movement through pipes and heating elements.
- Pressure-Regulating Valve Issues: The pressure-regulating valve ensures constant water pressure in your system. If malfunctioning, it could cause pressure to spike or drop unexpectedly.
High or low water pressure can disrupt your shower and appliances and strain the system, leading to long-term damage. Certified Plumbing of Brevard can diagnose the issue swiftly and take the appropriate steps to restore consistency. Detecting these signs early and contacting a professional can save you from unexpected system failures. Tankless water heater repair requires precision, and expert technicians have the tools and training to resolve these problems efficiently.
