What is a low-pressure boiler?

Low-pressure boilers operate at a lower pressure and reach lower temperatures than high-pressure steam boilers. Water in low-pressure boilers is not heated beyond 250ºF, and the steam pressure does not exceed 15 psi (pounds per square inch).

Low-pressure steam can be more economical to produce than high-pressure steam, as it requires less energy to create and does not lead to as much wear and tear on components.

Low-pressure steam boilers heat and provide hot water to hospitals, university campuses, office buildings, and multi-family dwellings. Low-pressure boilers can also provide steam used directly in a limited number of small-scale industrial processes.
