Let me give you a brief introduction of relevant knowledge. First of all, scale, commonly known as "water rust, water alkali", refers to the white block or powdery substance that the minerals contained in hard water attach to the container after boiling. The main components are calcium carbonate, magnesium carbonate, calcium chloride and magnesium chloride. In fact, due to the poor thermal conductivity of scale, the main harm of scale is to affect the efficiency of boiler, which will cause accidents such as boiler explosion in serious cases.
However, the impact on drinking water is not great. After all, we have boiled and disinfected the water at high temperature, and most of the scale is sediment, which will be filtered out, so don't worry too much, because if you boil a lot of scale, it means that this water contains more mineral components.
