Water boils at 100Â°C at standard pressure, no exceptions! However, the water temperature in the kettle is not even. Around the heating elements, the water rapidly reaches 100Â°C, even if the water in the rest of the kettle is cooler.
Every electric kettle I have ever used has heated the water until it is boiling vigorously and then stopped. As @Jolenealaska says, when it's boiling, it's boiling and the temperature that water boils at is 100C at sea level, minus about 1C for every 300m of altitude. â David Richerby Oct 20 '14 at 21:03.
