I tell my missus we should keep the boiler on high and turn the
thermostatic valves down in the other rooms but she thinks this will
use a lot more energy than turning the boiler down and having the
thermostatic valves fully open in the other rooms and put up with the
chill in the kitchen.
How can I explain to her that she is wrong?

Depends how big "a lot" is. Basically she's right that heating the
kitchen will use more energy than leaving it cold.
