A steam heating boiler operates at pressures not exceeding what value?

In a steam heating boiler, the operating pressure is a critical aspect of its design and safety. Typically, steam heating boilers used in residential and some commercial applications are designed to operate at a maximum pressure of 15 PSI. This pressure limit is significant because it allows for effective heat transfer while ensuring the safety of the system and its components.

Operating at or below this pressure helps to prevent potential hazards such as leaks and failures of steam lines, which can occur at higher pressures. Additionally, many safety regulations and codes dictate that steam heating boilers designed for low-pressure heating applications must not exceed 15 PSI. This regulatory standard helps ensure that the systems are safe to operate for their intended use without risking overheating or serious accidents.

While higher pressures can be used in specific industrial applications, standard steam heating systems are capped at 15 PSI to maintain operational safety and efficiency.
