What is the typical operating pressure for residential boiler systems?

The typical operating pressure for residential boiler systems is generally around 12 psi. This pressure range is appropriate for efficiently delivering hot water or steam to heating systems without excessive risk of leaks or failures. Most residential boilers are designed to function effectively within this pressure to ensure optimum heat distribution while maintaining safety standards. Operating at this level helps to avoid issues such as boiling and excessive wear on the boiler components, which can occur at higher pressures. It strikes a balance that allows for adequate heating while minimizing the risk of system damage or inefficient operation. Other pressures listed, while they might be used in specific applications or systems, are not standard for residential settings.
