What is the function of a water softener in a steam system?

A water softener plays a crucial role in a steam system by removing minerals that contribute to water hardness, such as calcium and magnesium. These minerals can form scale deposits on the heating surfaces of boilers and pipes, which can significantly impair heat transfer efficiency and lead to reduced performance of the steam system. By softening the water, the water softener helps prevent the buildup of these scales, thereby enhancing the longevity and efficiency of the equipment. This process ultimately ensures that the steam system operates smoothly and reduces the need for maintenance or repair due to scaling issues.
