That's what I used to do, but since going induction, the hob heats the

I cannot really see how that can be, if the Kw rating are the same. A
kettle is as near as matters delivers 100% of the energy direct into
the water, as the element is submerged directly in contact with the
contents. An induction hob has losses, the heat is also wasted heating
the container, then the contents.

People usually put more water than they need in the kettle, often
because of a rather high safe minimum level.

I always put more in than I need otherwise completly emptying the kettle results is some bits of calcium carbonate and other crude being poured into the cup and I'd rather it stayed in the kettle.
