Central Heating: Copper vs Plastic Pipework?

If you're replacing pipework why not hide it in the wall it makes things look so much better

Plastic pipe has a smaller internal diameter compared to the equivalent sized copper. Push fit fittings also have a much smaller internal diameter. This can be a consideration if flow rates and pressure loss are a concern over longer runs, as you may need to go one pipe size bigger.

Other than that, I've seen both push fit fittings fail and soldered fittings fail. Both usually down to installer error.

The pretty pictures are on p2. The plastic joins you see were all replaced with copper.

Yes, that is pretty.

Plastic would have done the job just as well. But, man, it would have looked... :-p

 Any drop down legs (vertical pipework) will be boxed in with plasterboard.

Plastic trunking would be easier.

From memory the issue was that those joints would be buried in screed and you are not supposed to do that with push-fit unless you put them in an accessible 'box'
