Some boilers of this size are also used at paper mills and institutions and for other industrial applications.
Low-Pressure Boiler Definition. In a low-pressure boiler the pressure does not exceed 15 psi, and hot water heating boilers are not designed to exceed over 260 psig. The temperature in a low-pressure boiler will not rise above 250 degrees F. Because these types of boilers operate at lower pressures, they don't need to be monitored regularly
