does it take longer to boil a full kettle?
It’s often assumed that it takes longer to boil a full kettle, but the truth is, it actually takes about the same amount of time as boiling a half-full kettle. This is because the heating element in a kettle is designed to heat a certain amount of water, regardless of how much water is in the kettle. So, if you put less water in the kettle, the heating element will simply work harder to heat it up to the same temperature. In fact, some people even claim that it actually takes longer to boil a half-full kettle, since the water has more space to move around and therefore takes longer to come to a boil. However, this is a small difference, and for most people, it’s not noticeable. So, if you’re wondering whether it takes longer to boil a full kettle, the answer is: no, it doesn’t.
what is cheapest way to boil water?
