Generally speaking, the volume of a kettle is the maximum amount of water it can boil, so the kettle can burn up its own volume of water at most. If the kettle can boil 1.5L of water, the water will overflow after boiling.

Although the volume of the kettle is fixed, we don't necessarily need to burn the whole kettle when boiling water. We can measure the amount of water we need according to our own needs, and then pour it into the kettle to boil. So the actual amount of water that a kettle can burn is determined according to the amount of water we need.

And the speed of boiling will also affect the amount of water we can boil, because if the kettle boils slowly, we may have to wait a long time to boil the whole kettle, which will affect our water consumption time and demand.

Tips for choosing a kettle

The capacity of electric kettle is the first factor to be considered when choosing. Generally speaking, the capacity of domestic electric kettle is between 1 and 2 liters, which can be determined according to the number of family members and the use demand. If there are many family members or often need a lot of hot water, it is recommended to choose an electric kettle with a large capacity, which can meet the water demand of more people at one time and avoid frequent water addition.

The heating speed of electric kettle directly affects the convenience of our use. Generally speaking, a better electric kettle should have the ability of rapid heating, which can heat the water to a boiling state in a short time. When we are in urgent need of hot water, quickly heating the electric kettle can save our precious time and improve our living efficiency.
