At what temperature does the temperature relief device typically open?

The temperature relief device typically opens at approximately 99°C (210°F). This temperature setting is crucial as it provides a safety mechanism to prevent excessive pressure build-up in a system, such as a hot water tank or boiler. When the temperature reaches this threshold, the device activates to release excess pressure and steam, ensuring the safe operation of the equipment.

The selection of 99°C is designed to strike a balance between safety and efficiency, as it is near the boiling point of water at standard atmospheric pressure. This point ensures that the risk of overheating, which could lead to equipment failure or dangerous situations, is mitigated effectively.

In settings where water or steam can become dangerously pressurized, this safety feature plays a vital role in protecting both the equipment and the surrounding environment, ensuring compliance with safety standards.
