What is one common safety concern when working with hydronic systems?

Pressure buildup in pipes is a significant safety concern when working with hydronic systems. These systems use water or other fluids to transfer heat, and improper management of this fluid can lead to dangerously high pressure levels within the pipes. If the pressure exceeds the design limits, it can result in pipe bursts or failures, leading to flooding, water damage, and potential injury to individuals nearby.

To mitigate these risks, it’s essential to regularly check and maintain pressure relief valves, ensure that expansion tanks are functioning correctly, and monitor the overall system for leaks or blockages that could contribute to excessive pressure. Understanding the mechanics of pressure buildup is crucial for HVAC professionals to ensure both system efficiency and the safety of the environment they work in.
