When is a hot water boiler considered a high temperature water boiler?

A hot water boiler is classified as a high temperature water boiler based on its operating temperature. Specifically, it is considered a high temperature water boiler when its operating temperature exceeds 120°C. This classification is important because high temperature water boilers operate at temperatures that can pose significant safety and operational considerations, necessitating specific design standards and safety measures.

Operating at temperatures greater than 120°C allows for more efficient heat transfer and utilization in various applications, particularly in industrial settings. It also signifies that the boiler can handle increased thermal stresses and pressures, requiring precise engineering to manage these conditions safely.

Understanding this classification helps operators and engineers ensure compliance with relevant codes and standards, promoting safety and efficiency in boiler operations.
