Copper pipe or plastic pipe for central heating

[Pipe slice]

Plastic has its uses like for ufh but for a first rate install you can’t beat a copper installation with capillary soldered joints imo

Copper pro’s
It lags better
It doesn’t sag as much
Its rodent proof
It’s cheaper than plastic if a lot of fittings are required
It’s a better job
Can be used for dhw secondary return
There’s recycling opportunities

Plastic pros
Quick to install
Less skill required to install
Lighter to work with
No blow torch required
Cleaner to work with
