Residential steam boilers typically operate at less than what psi?

Residential steam boilers are generally designed for low-pressure applications. The common operating pressure for these systems is 2 psi or lower. This low-pressure operation is crucial because it ensures safety and efficiency for residential heating systems, which do not require the high-pressure capabilities that might be necessary in larger industrial applications.

At pressures around 2 psi, the steam produced is sufficient to transfer heat effectively for residential heating without the risks associated with higher pressures, such as potential for equipment failure or dangerous situations. Steam systems at higher pressures typically belong to industrial settings where greater heating needs exist, making the application of such pressures inappropriate for standard residential settings.

Thus, the choice of 2 psi reflects the typical operational limit for residential steam boilers, aligning with safety standards and operational efficiency for home heating systems.
