Demister pad wiring question...

[JohneeBoy]

Is it normal to wire a demister pad/mirror to the main circuit/shaver point so the thing is always on? This is how one has been fitted. I don't see how this can be right other than having the advantage of working without having to put the lights on. Any advice please?

This is what I expected and would have done myself. It's a new build so we weren't involved in the decision.

My cheap Chinese one came wired permanently on - I changed it to a switch.

I presumed it turned on with the mirror light as my old one had.

There should be a way to isolate it. I'd code it improvement advised on an inspection.

As said lazy/inept installer afterthought; should be with main lights.

Ours is wired like this - was done as part of a full rewire. I also thought it strange that the fan is wired to the lights, but the mirror isn't.
