You're very much on your own when it comes to your definition of

The application of efficiency to a radiator isn't just heat out / heat
in. Best get used to it or be forever stuck in the past and viewed as
senile.

come back when you've got a fact to offer us.

The fact is some of us have moved with the times and accept new or a
change of meaning to a word.

It's another fact others are in denial, suffering from senility.

The definition of energy efficiency has not changed. Nor has the looser usage of the word efficiency in other contexts. Some people believe anything.
