Unlike traditional water heaters that store gallons of water in a tank, tankless systems heat water on demand, delivering a continuous supply to your home without the need for a storage reservoir. These units are incredibly energy-efficient, as they only consume energy when hot water is needed, which can reduce overall utility costs.

At Mattex Heating, Cooling, Plumbing, Sewer and Electrical, we can provide reliable assistance with tankless water heater maintenance, repairs, installations, and replacements.

Why Is Tankless Water Heater Maintenance Important and What Does It Entail?

Tankless water heaters require regular maintenance to operate effectively and maintain their longevity. Without proper upkeep, these systems can experience issues like mineral build-up, decreased efficiency, or even breakdowns. Hard water, for example, can lead to significant scaling inside the unit, reducing the system's ability to heat water adequately. Over time, this can strain the heating elements and limit the lifespan of the heater. Regular maintenance helps to prevent these issues so that the water heater continues to run efficiently and reliably for many years.

A typical maintenance visit for a tankless water heater involves several key steps. Our technicians can descale or flush your system to remove any mineral deposits that may have accumulated, especially in areas where hard water is prevalent. We accomplish this by circulating a solution, often in the form of vinegar or a descaling agent, through your system to dissolve calcium and other mineral build-up. Additionally, we can inspect and clean your system's filter, which can collect debris over time and obstruct water flow.

Signs Your Tankless Water Heater Needs Repairs

Recognizing the signs that your unit requires repairs can help you address problems early, avoid costly breakdowns, and maintain consistent performance. Our plumbing technicians at Mattex Heating, Cooling, Plumbing, Sewer and Electrical have the skills, experience, and tools to resolve many tankless water heater problems in a single visit.

Don’t wait to schedule an inspection if you are dealing with any of the following issues:

  • Fluctuating water temperature. If you notice that the water temperature is inconsistent – switching between hot and cold unexpectedly – your tankless water heater’s heating element may be malfunctioning, or there could be an issue with its flow sensors. Mineral build-up within your system could also restrict efficient water heating. Addressing this issue promptly is vital to avoid further stress on your unit.
  • Unusual noises. Strange cracking, hissing, or popping sounds coming from your water heater could indicate sediment build-up within its internal components. These deposits reduce efficiency and can damage parts of your heater over time. Persistent noises may require flushing your system or replacing worn-out components.
  • Reduced water pressure. A noticeable drop in water pressure when using hot water may point to blockages within your system, such as mineral build-up in your pipes or a clogged inlet screen. These types of water supply issues can strain your unit and reduce its operational lifespan if left unchecked.
  • Error codes on the display. Many modern tankless water heaters are equipped with diagnostic tools that display error codes when something is wrong. If an error code appears, referencing the user manual can help identify the issue, whether it involves gas supply, ventilation problems, or electrical malfunctions.
  • Discolored or odorous hot water. If your hot water has a rusty or cloudy appearance or if it smells unusual, bacteria may be growing in your water lines, or there may be corrosion somewhere within your system. A professional inspection can diagnose if this is an internal issue needing repair or replacement of components like the heat exchanger.
  • Water leaks around your unit. Water pooling around or dripping from your tankless water heater suggests a potential leak in the plumbing connections or internal sealing. Leaks can cause water damage and signify a more serious problem with your system’s internals that require immediate repairs.
  • Higher energy bills. A sudden increase in energy costs when using your tankless water heater might mean your system is working harder than usual to heat water. This could be due to sediment build-up, failing components, or improper installation.

When Do I Need to Replace My Tankless Water Heater?

Tankless water heaters are designed to be long-lasting and efficient, but like all appliances, they have a finite lifespan. Over time, wear and tear, as well as external factors, can diminish their reliability and performance. Our Champaign tankless water heater services include expert assistance with determining whether replacing your unit is necessary or if regular servicing and targeted repairs will suffice.

You may need to consider replacing your tankless water heater in any of the following scenarios: 

  • Your system is nearing the end of its lifespan. On average, a tankless water heater should last between 15 to 20 years with consistent maintenance and proper usage. If your unit is approaching or has exceeded this timeframe, it may be more cost-effective to replace it rather than continuing to repair it. Older units may also lack the efficiency and advanced features of newer models, leading to higher operational costs and reduced performance.
  • You are paying for frequent and expensive repairs. If you find yourself constantly calling a technician to fix your tankless water heater, it might be time to consider a replacement. Frequent breakdowns not only disrupt your access to hot water but can quickly add up in repair expenses. If the cost of a single major repair approaches or exceeds the cost of a new unit, replacing the system becomes the smarter long-term choice.
  • You notice decreased energy efficiency. One of the key appeals of a tankless water heater is its energy efficiency. However, as your system ages or develops issues like sediment build-up, its efficiency may decline, causing higher energy consumption. If you notice increasingly high energy bills despite no change in water usage, your unit may no longer be operating efficiently and might need to be replaced.
  • You are dealing with persistent issues with water temperature. Uneven or insufficient water temperature is a common sign that your tankless water heater is no longer performing as it should. Over time, failing components, internal corrosion, or scale build-up can hinder your system’s ability to produce consistent hot water. If flushing your system or replacing small parts does not resolve the issue, a new unit may be required to restore reliable performance.
  • You observe visible corrosion or damage. Corrosion and physical damage to your tankless water heater can compromise its functionality and safety. While some external issues may be repairable, internal corrosion typically signals the end of your water heater’s usability. Leaks caused by rust or damaged components are often irreparable and require a complete replacement to prevent further problems.
