A common thing for most homeowners is to fill a kettle with water and boil it or heat it up as needed until it runs out.
At the same time, warnings are heard from all sides that water should not be boiled several times, that it is harmful and spoils the taste of drinks. Is this really true?
What happens to the water
According to experts, repeated boiling of water affects its composition.
Due to the evaporation of some of the water, the liquid remaining in the kettle supposedly becomes more concentrated and contains more minerals and salts.
But there is other data. If you want, you can find information that re-boiling leads to the formation of almost carcinogenic substances in water.
How it really is
Research shows that repeated and subsequent boiling will not make water hazardous to health.
The amount of harmful substances formed in it is so small that the water simply cannot cause harm to health.
A much more important point is the quality of the water and the limescale that forms in the kettle.
