When the water in the heating system is heated, the dissolved oxygen proportion which has a low heat conductivity increases. Hydromx water mixture has a better heat conductivity compared to water due to the deficiency of oxygen. It prevents any damages during freezing such as cracking etc. Because the freezing point is lower than that of the water. It prevents calcification. Because the lime which the city water contains decreases as per the proportion of Hydromx, it protects from the harmful effects which the sytem is exposed to due to calcification..
