When is the hot water kettle usually ready in the hotel?

It depends on the power and capacity of the electric kettle. Generally speaking, if the power is about 1000 watt and the capacity is below 2 liters, it can be boiled in about 10 minute.

Generally, a kettle can be filled with water from two thermos bottles, and the heating power is 1500 watts. When the ambient temperature is about 20 degrees, it takes about 15 minutes to boil a pot of water. The weather is cold, and the time is slightly longer. According to the current temperature, the time is shorter. If you buy a new kettle, you can choose to call it a kettle. When water boils, it will make the sound of train whistle. Generally, a 500w kettle with the size of 1.5L needs to be burned for 15-22 minutes. If it's automatic, then leave it alone and let it burn there. It will jump when cooking, so don't worry about spillage.
