Then, why is the soft water needed for the steam boiler? If the supply water contains the hardness, the hardness is condensed in the boiler as heating, becomes the scale, and then adheres inside the water tube. Then, the heat efficiency declines remarkably as the scale adhesion because the heat conductivity of the scale is very low.
