Would electricity be cut from a shower if flow is only restricted beyond the outlet?

The reason for my rather odd question is that I have a redundant electric shower in the bathroom which is situated very close to the basin. I have a cunning plan to divert its hot water into the cold basin tap, which would not only provide almost-instant hot water when usually it's lukewarm, but would also save most of the water wasted by waiting for the hot to come through because
⦁ the pipework from the cylinder is double the length I propose
⦁ That pipe is 22mm whereas in my scheme, I'll be only be using 15mm pipe
⦁ The water from the shower will be so hot that I'll need that otherwise wasted cold water to mix in.

The only snag in this that I can think of is the safety aspect in ensuring power is cut as soon as the basin tap is closed, but I'm unsure how showers are designed to detect the ceased flow when their water knob is turned off.

Showers MUST be open vented- they should not have a tap or anything that will restrict the flow after the shower outlet


Read the instructions - most are available as free downloads from the manufacturer sites

its important enough to repeat

NO NO NO

the above advise could save you a rather nasty boiling hot water pressure explosion and nasty facial burns.

You may be able to use the shower wiring with one of these making installation easier or cheaper.
