The standard operating pressure for most commercial boilers typically falls between 15 psi and 100 psi. This range is considered appropriate for a variety of applications such as space heating, water heating, and process heating. Operating within this pressure range allows boilers to function efficiently while maintaining safety standards.

Boilers operating at this pressure are designed to handle the demands of heating systems in commercial settings without risking damage or requiring extensive maintenance. Higher pressure settings, such as those above 100 psi, may be utilized in specific industrial scenarios but are not standard for general commercial use. Thus, understanding the typical range of 15 psi to 100 psi is crucial for safe and efficient operation of commercial boilers.
