Why you should never reboil water again?
The Main Risk of Reboiled Water
Reboiling water drives out dissolved gases in the water, making it “flat.” Superheating may occur, making the water hotter than its normal boiling point and causing it to explosively boil when disturbed. For this reason, it’s a bad idea to reboil water in a microwave.
Is kettle boiled water safe to drink?
A Boil Water Order is typically issued to a drinking water system owner when the RMOH feels that, to protect public health, water should be boiled before it is consumed. Boiling water will kill any potentially disease-causing microbes, making it safe to drink.

What triggers an electric kettle to turn off?
A channel within the kettle, typically inside the handle, carries steam from the top of the boiling interior down to the thermostat (often near the base), where the temperature rises very rapidly from around ambient to near 100°C as soon as boiling starts. This causes the disk to snap and disconnects the power.
