Many Americans do not own kettles, and the hassle of boiling water on them probably does not seem worthwhile. However, some folks in the United States have opted to invest in a kettle, and it’s been fun to see them discover the delights of instant teas. If you’re wondering why Americans don’t have as many kettles as British, it’s because the voltage in the United States is lower. The majority of residences in the United States are powered by 100-127 volts, but the United Kingdom and many other nations use 220 to 240 volts. Electric kettles in the United States do not boil water as rapidly as they do in the United Kingdom due to the lower voltage. Consequently, they haven’t taken off in the United States. It takes around 355 kilojoules of energy to increase the temperature of one liter of water from 59℉ to bursting at 212℉. Typically, a UK kettle delivering 2800 joules per second would take 127 seconds to boil, whereas a US kettle supplying 1500 joules per second will require 237 seconds, more than a half longer. The majority of kettles used in the United States are stovetop kettles. You can add the water to the kettle, then heat it on a gas or electric burner. The water boils, creating steam, escaping from the kettle’s spout, making a whistle.
