When operating a hydronic system, what is critical to monitor for safety?

Monitoring water temperature and pressure in a hydronic system is critical for safety because both factors directly influence the overall performance and safety of the heating or cooling processes.

Water temperature is essential to ensure that the system operates within safe limits, preventing overheating that could lead to equipment failure or even hazards like bursting pipes or boiler explosions. High temperatures can indicate a malfunction or blockage in the system, which must be addressed promptly.

Water pressure is equally important, as it maintains the proper flow of the water throughout the system. If the pressure is too low, it could lead to insufficient heating or cooling; if it's too high, it poses the risk of leaks or catastrophic failures due to excessive stress on the components.

In contrast, focusing solely on water pressure, water level, or air quality does not provide a comprehensive view of the system's operational safety, as these factors do not encompass the critical aspects of temperature which can also indicate the functioning state of the entire system. Monitoring both temperature and pressure allows for proactive measures to maintain the integrity and safety of the hydronic system.
