Corrosion and encrustation is "the obstinate disease" for water heaters, boilers, hot water pipes, and other equipment, which give rise to 30% of failures or troubles for the above equipment. In China, mineral content and furring are relatively high in most of the freshwater regions in highland, especially Guizhou. The water in that place is quite harmful for electric water heaters. After years of experiments, Weber found it is a very effective and economic way to use magnesium alloy anode protection among many decontamination methods. According to reasonable calculation, this new technology could protect the equipment and prolong its life to several times antisepticising and decontaminating automatically.
