Many tea kettles are designed to be placed on a stove, while others can be electric, allowing for quick heating of water. Tea kettles are often used to prepare hot beverages, especially tea. They come in various sizes and styles, catering to different preferences and kitchen aesthetics. Some kettles feature whistles that signal when the water has reached a boil, adding convenience to the brewing process.
