Does the underfloor heating pipe have an aluminium core?
No, the pipe we use does not. Pipe with an aluminium core, or Alpex, was originally developed for use with higher temperature domestic hot water plumbing and radiators. Some underfloor heating supply companies use Alpex, but it can be difficult to work with because it is not easy to reshape if you get it wrong and need to reposition the pipe. Also, Alpex is more expensive than normal plastic Pex pipe. Some people believe that using Alpex pipe will protect the pipe from accidental damage, but Alpex is just as easy to put a nail through as any other.
