The bulk of the heat loss has nothing to do with the

Civilised countries have kettles that switch off on boiling.

But how quickly they do that clearly does affect their efficiency,

And if you make it react very quickly, you increase the sensitivity and
make it liable to false tripping.

Turns out you dont get false tripping.

I do on mine.
Because the thing that switches is a mechanical thing based on teh bi-metalic strip this sometimes discoinnects before teh kettle has actaully boiled.
