New radiator, plastic polypipe and earthing query

mr_vampy

Hi,
Hoping someone here can be kind enough to give me some advice/info on a query for a friend of mine.
He's planning to replace his old single panel radiator to a new double panel one. At the moment the two pipes going into the radiator comes up from the centre and goes outwards to the radiator valves with lots of exposed pipework. He would like to get rid of the majority of the exposed pipes and as plastic polypipe is flexible, he wants to know whether he can join plastic polypipe to just above where the copper pipes comes up from the solid floor and directly into the radiator valves. He realises that using the plastic pipe will break the continuity of existing metal pipes which is used for earth bonding. How would he go about reinstating the continuity?
Any advice/info would be greatly appreciated.
Thanks

If it already has a earth cable the attach it to the rad, if not? then no need.

That doesnt make sense.

Can you explain again please.

He does not need to reinstate any continuity as central heating pipes are not used for earthing, nor do they need to be earthed.

The exception is in a bathroom under 16th Edition Wiring Regulations where metallic services entering a bathroom must be cross-bonded - this is not the same as earthing.

Is this in a bathroom?

We're on the 17th edition now;)

I know - and the 17th Edition does not require equipotential bonding in bathrooms if there are RCDs. But if the installation was designed to the 16th Edition then RCD protection cannot be assumed and the bonding would have to be reinstated for safety.
