Signs Your Tankless Water Heater Needs Repair

Tankless water heaters have become increasingly popular due to their energy efficiency and space-saving design. Unlike traditional water heaters with a storage tank, tankless models heat water on demand, providing a continuous supply of hot water as needed. 

However, like any appliance, tankless water heaters are prone to wear and tear over time. Recognizing the signs of a malfunctioning tankless water heater is crucial for preventing costly repairs and ensuring an uninterrupted hot water supply. In this blog, we’ll explore the common signs that you need tankless water heater repair in Dover, PA, and potential causes and solutions.

Lack of Hot Water

One of the most obvious signs that your tankless water heater needs repair is a sudden decrease in the hot water supply. If you notice that your water isn’t getting as hot as it used to or that you’re running out of hot water faster than usual, it could indicate a problem with your water heater. 

Mineral buildup in the heat exchanger or sediment accumulation in the pipes can hinder heat transfer, resulting in insufficient heating. To address this issue, it’s essential to contact our team of professional plumbers. We can flush the system and remove sediment buildup and any obstructions, restoring the heater’s efficiency.

Fluctuating Water Temperature

Another sign of a malfunctioning tankless water heater is fluctuating water temperature. If you experience sudden changes in water temperature while using hot water, it could signal underlying issues with your heater. 

A broken flow sensor can cause a tankless water heater to experience temperature fluctuations. Sediment deposits on the heating element can also cause this. Contact us for an appointment so we can assess the system, determine the cause of temperature fluctuations, and restore the system’s optimal performance.

Strange Noises

Unusual noises from your tankless water heater during operation can indicate potential problems. Popping, rumbling, or banging noises may be caused by scale buildup or loose components within the unit. Scale accumulation can interfere with heat transfer, while loose parts can create vibrations and noise. Scheduling regular maintenance to fix loose components and descale the system can help prevent further damage and prolong the heater’s lifespan.

Unusual Odors

Strange smells coming from your tankless water heater should not be ignored, as they could indicate serious issues such as gas leaks or electrical problems. A distinct odor similar to rotten eggs may indicate a gas leak, while a burning smell might suggest electrical issues or overheating. If you detect any unusual odors, it’s essential to immediately shut off the unit, ventilate the area, and contact a professional plumber for inspection and repair to ensure safety.

Recognizing the signs that indicate a tankless water heater needs repair is essential for maintaining a reliable hot water supply and avoiding an early replacement. Remember to schedule regular maintenance and contact us if you notice any signs of malfunction to keep your tankless water heater running smoothly for years to come.
