Can Copper/Silver ionization be used successfully on non-hot water systems (i.e. cold water)?
Yes, Copper/Silver ions are not affected by water temperature and have been used successfully in hot and cold water applications, unlike Chlorine and Chlorine Dioxide which are temperature sensitive and dissipate at warmer water temperatures. However, Legionella is considered to be far more prevalent in warm water temperatures and once the hot water system is disinfected the problem of Legionella is eliminated through the entire water system in most cases.
