I did some sums when I first heard of them, and I agree, a kettle used

maximum energy efficiency.

But for instant cuppa tea convenience - and the reality that no-one
but me will ever gauge the kettle contents accurately - if they live
up to the advertising, I will eventually get one.

But the boiling taps might be just as wasteful of energy as an
overfilled kettle considering that they keep a supply of permanently
heated water in a small tank under the worktop.

Do they work by electricity/coal/gas/oil/horse gin/nuclear energy? ;-)
