What is the maximum operating temperature that should not be exceeded in hot water boiler operation?

The maximum operating temperature that should not be exceeded in hot water boiler operation is 121 degrees Celsius. This temperature is significant because it relates to the safe and efficient operation of hot water systems. Exceeding 121 degrees Celsius can lead to increased pressure within the boiler, thereby increasing the risk of mechanical failure and potential safety hazards, such as steam explosions or structural damage to the boiler.

Maintaining the temperature at or below this threshold helps ensure that the water remains in a stable state and that the system operates within its designed safety limits. It balances efficiency and safety, preventing overheating and ensuring the longevity of the boiler.

Choosing a temperature higher than this threshold, such as 130 degrees Celsius, could compromise safety protocols and exceed the design specifications for typical hot water boilers.
