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

for longer than necessary after the water starts boiling.

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 don’t get false tripping.

People will simply return kettles as not fit for purpose if they regularly
cut-off too soon or even worse, cut-off and won't reset for some time.
