The Dangers of Distilled Water in Boilers: Fact or Fiction?

16/1/2014 · Distilled water corrodes; hard water scales. In the steam boiler, it's water + minerals in, and steam, no minerals out. So any minerals you add will build up over time. If you don't introduce any, some will build up anyway due to the leaching of the metal ions. In other words, the corrosion ends as the minerals build up.
