Sometimes referred to as electric kettles, water boilers/warmers are an indispensable countertop kitchen appliance. Water boilers and warmers are powered by electricity and usually have about a 28 to 40 cup capacity and are designed with precise temperature settings so you can arrive at the temperature you need. They can be used to make coffee, tea, or even steaming vegetables without having to wait for a stovetop to boil. Water boilers boil the water and then cool it to your desired warm setting. In other words, you can have any temperature water at any time during the day without having to wait for a stovetop boil or wait for the water to cool, the device does all this for you automatically. You can also set it to warm if you don’t actually need the water to be at boiling temperature. Most models today have LED displays indicating what temperature the water is at any given time throughout the day.
