The glass kettle with temperature selection is ideal for tea drinkers, as different types of tea require water at varying temperatures. The temperature can be individually set and increased at any time during the heating process. The heating process starts by pressing the on/off switch, which blinks until the desired temperature is reached. An acoustic signal indicates that the water is ready. Additionally, the kettle features a keep-warm function that maintains the water temperature for 30 minutes. This function is activated by pressing the keep-warm button, which stays lit until the time runs out or the button is pressed again. The cordless kettle sits on a separate, flat heating base, allowing for comfortable handling.
