A boil kettle is a kitchen appliance designed to heat water quickly to its boiling point. It typically features a heating element and a container, often made of stainless steel or plastic, where water is stored. Many boil kettles come with an automatic shut-off feature that activates once the water reaches a boil, ensuring safety and energy efficiency. These kettles are commonly used for making hot beverages like tea or coffee, as well as for cooking purposes such as boiling pasta or preparing instant meals. Some models also offer temperature control settings, allowing users to heat water to specific temperatures for different types of tea or other beverages.
