Really.

Well you can if you want, but foolish to do so.

Using the hot water of mains pressure systems when filling kettles
reduces
expensive electricity consumption.

As does filling the kettle from a hot water cylinder.

Once again, "You can't drink the water from a tank". Or to be more
specific, it is not drinking water and not recommended for drinking. Drink
at your own risk
