What is a common concern with hydronic systems if not maintained properly?

Corrosion within pipes is a significant concern in hydronic systems if they are not properly maintained. Over time, the presence of oxygen and other contaminants in the water can lead to rust and corrosion within metal piping. This degrades the integrity of the pipes, potentially leading to leaks, pressure loss, and ultimately system failure. Maintaining the correct water chemistry, including pH levels and oxygen content, is vital to prevent corrosion. Regular system maintenance, including flushing and using inhibitors, is necessary to protect the pipes and ensure the longevity of the hydronic system.

In contrast, while air circulation, water temperature, and water pressure can impact system efficiency and performance, they do not pose the same long-term structural risk as corrosion. Air circulation issues can affect heat transfer but are often easier to remedy. Similarly, water temperature and pressure can fluctuate for various operational reasons, but these conditions do not lead to the physical degradation of the system's components like corrosion does.
