Is My Water Heater Supposed to Leak?

Tankless water heaters have gained popularity for their energy efficiency and space saving benefits. Unlike traditional tank style water heaters, tankless models heat water on demand, eliminating the need for a large storage tank. Some homeowners may be concerned when they notice water around their tankless water heater. While most often this is a result of processes not directly related to a leak in the system, it can raise concern and have a homeowner looking for tankless water heater services in Boynton Beach, FL. Let’s investigate whether your tankless water heater is supposed to leak and the potential causes behind any leaks.

Understanding Tankless Water Heaters

Before addressing the issue of leaks it’s important to understand how tankless water heaters work. These units heat water directly as it flows through a heat exchanger providing hot water instantly when you turn on a faucet or shower. They do not store water, as traditional water heaters do. This eliminates the risk of water damage due to a ruptured tank.

Possible Causes of Leaks in Tankless Water Heaters

  • These systems can produce condensation. This is especially true when heating cold water. This condensation may drip from the unit creating the appearance of a leak. Condensation is a normal byproduct of the heating process and is generally not a cause for concern.
  • Like any plumbing system, tankless water heaters have various connections. This includes inlet and outlet pipes, gas lines and electrical connections. These connections can become loose or develop minor leaks over time. Routine maintenance and inspection can help identify and address these issues.
  • The systems are equipped with pressure relief valves as a safety measure. If the pressure inside the unit becomes too high the valve may open and release water. This can make it look like the unit is leaking.
  • There is a drain valve used for flushing the system to remove mineral deposits. If this valve is not closed tightly after maintenance it can produce the same effect.
  • Tankless units may have a TPR valve. This valve is designed to release extra pressure and hot water if the temperature or pressure within the unit becomes too high.

When to Seek Professional Help

While some minor condensation or occasional drips around your system can be normal the presence of persistent leaks or any unusual behavior needs further inspection. It’s important to address leaks quickly to prevent water damage to your home and guarantee the continued safe operation of the unit. 

In general, tankless water heaters should not leak under normal operating conditions. However, some minor condensation or occasional drips may be normal. This is especially true during the heating process. It’s important to differentiate between normal operation and problematic leaks. Regular maintenance and professional inspections can help make sure that your tankless water heater functions efficiently and safely without any unwanted leaks!
