Also, why would you post a thread which begins "Wiring questions" in the Plumbing section?

On a Persimmon Homes house orignal wiring I found the class II thermostat on the tank used green/yellow as a line wire. With that in mind how can one really answer questions like that.
Only one answer is get an electrician. The "doitall" answer could well be what would get it running however I would never tell some one to connect an earth wire to a line connection even if it would make it work.

Well, the OP has gone and done it that way, it seems.
I guess he looked at the range of opinions on offer, discounted the huge majority saying not to use the G/Y for anything other than an earth, and went with that moronic f***wit doitall's advice because that was easy.
What a t**t.

514.4.2
Which refers to not sleeving green/yellow single core cables for any other purpose.
This was pointed out to me in the office when I tried to pull up a 3core flex to a photocell with the green/yellow mis-used as being incorrect. Apparently the reg has had a slight re-wording to suit harmonisation with europe.
I simply stated that may well be the case, but it doesn't comply with the final paragraph of 411.3.1.1 and was still wrong
There's always our old friend 134.1.1 
looks like you sparks are all wrong then.
It's perfectly acceptable to use an insulated green and yellow for heating controls, provided it's oversleeved and identified.
Confirmation from NICEIC, and building control, still waiting for John at NAPIT to reply.
Uninsulated earths cannot be used.
Get to grips with the regs guys.

To answer Adam before I retreat back to the heating forum.
They did say that heating controls is the only instance that you can oversleeve the green and yellow.
Well, IMO that does seem to be a particularly daft thing for 'them' to say - regardless of the rest of the debate about the interpretation of the wiring regs, one thing which is clear is that BS7671 certainly doesn't single out 'heating controls' as being different from any other application.
Kind Regards, John
What makes heating controls any different?
The correct answer is 'nothing'.
You can get 7 core flex easily. If it's not enough, install two cables.
