Oh dear... how old is "old stuff" ?
... Actually, looking at their site they still use the same stuff they
were using when I did ours.

My mate used Nu-Heat a year or 2 before us (well, his builder did) and
said they provided brass manifolds for the floor lops which the builder
just cemented in with the rest of the loop. He's sold that property now.
