A kettle is often the first kitchen appliance you buy. However, so that you don't have to buy several kettles in a row - because the initial option is not suitable - it is smart to think about how many people you will be boiling water for in advance. In addition to the size, water chains are not only in different colors, but also in different materials, such as porcelain, glass and of course stainless steel and plastic. The range also includes kettles with different functions for when you only need to heat water.
