A water metering device 10 usable to allow electric kettles to be charged with metered quantities of water. The device is inserted into a kettle to intercept and divert water used to charge the kettle. It is supported at or near the top of the kettle body and has a metering chamber 20 formed with an uncontrolled outlet aperture 20a through which water can pass into the kettle, and the relative dimensions of the chamber and the outlet aperture are configured such that, once the chamber has been filled with water, the amount of water in the chamber, together with the amount of water that has by then already entered the kettle through the outlet aperture, amounts in total to a charge of water. Should the user wish to charge the kettle directly, it is only necessary to ensure that the water flows through the by-pass path 22, which guides unmetered quantities of water directly into the kettle. |
