I have a heating system from 1988 - it has the small(est) pipes and the
double entry valves in one end of the radiators (not a bad idea - seems to
work well)

I would quite like to move a radiator about 10 feet along a wall. The walls
are dry lined and the pipes are behind the plasterboard until they emerge
into the valve.

To move the rad, I guess I need to cut off the pipes where they drop down
the wall and extend them to the new location.

Question One: Should I use copper or plastic for this:

Question two: Should I try to cut and remove a strip of plasterboard and
re-use it to cover the extended pipe route and the area of the pipe joint?
Any tips on making this invisible?

Question three: should I re-use the double ended valve (Twinfast?) or change
to conventional?

Many thanks to anyone who can build up my confidence to do this neatly.

Copper as that is what already is there.

Just cut away the plaster board, fit new pipes and cover it. Wrap new pipes
in plastic tape to protect them from plaster.

Question three: should I re-use the double ended valve (Twinfast?) or

Use the double ended valve.

Use a stanley knife to cut the slot in the plasterboard, takes a few
cuts to go right through but it is really neat and you will be able to
reuse the board you cut out if you remove it carefully. You might need
to drill a small hole to start it off.

When I first saw someone cutting a hole like this I didn't believe it
would work, but it's definitely the neatest way to do it.

If the system is working well the extending the length of the microbore
pipes might cause problems, because if the pipe run becomes too larg
relative to the othr radiators then not enough heat might come to the
moved rad.

The double ended valves are trouble, one valve each end is better and a
far wider choice of fittings is available. Although you seem happy (so
far).

I have no opinion of the plastic or copper is you are keeping the pipes
hidden. Trunking is sold to hide microbore pipe, but then the trucking is
more obtrusive than the pipes!
