You should not drink Tap water. Boiling water only kills parasites. It does not filter water from other harmful residues not to mention the excess salts and unwanted minerals. Rust within residential pipelines could cause serious problems as well.
Even bottled water would create a layer or salts in electric water kettles. The rate could be slower for the build up though. When you boil water, pure water evaporates leaving salts at the bottom of the boiler. The more you do this, the thicker and more visible those layers become.
