Generally "the soft water" and "the hard water" often mentioned in our lives refer to the content of calcium and magnesium ions in the water.
If the water hardness is too high, it is lead to produce scale in the state of white sediment, and scale adheres to the heating container or heating tube, which will prolong the heating time after a long time scaling and in-crease energy consumption ac- cordingly.
