HOW DO ELECTRIC KETTLES WORK?
These are the components inside a kettle responsible for bringing it to a boil
WORDS AILSA HARVEY
People have been boiling water for thousands of years for purposes such as killing bacteria, cooking or brewing a drink. Whereas some of our early ancestors would have needed to build an open fire to get their water bubbling, today we can boil water in a couple of minutes simply by using a kettle. Electric kettles convert electrical energy into heat energy, and this is transferred to the water much more efficiently than by an open fire. While an open fire allows heat to escape into the surrounding air, kettles include a lid to trap the heat inside and insulation around the element that heats the water.
