You can't use a switched one of any variety for supplying a boiler.

I don't, having made my own decision 26 years ago. Is it now in the
regs?

What's the logic behind that directive ?

my logic was that removing power to the system, which includes the pump,
could result in overheating of the boiler and a consequent shut down, so
that when power was restored the boiler wouldn't restart. This could, if I
wasn't at home, result in expensive call out charges.
