Difference Between Low- and High-Pressure Boilers …

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
