There are 2 ways to install the pex for retrofit heating: attached to
the underside of the floor with metal fins underneath the pex to
distribute heat, or hanging below the floor about 10cm with
insulation below the pex. The 2nd option makes for a quiet system,
as the pex expands 10% when hot and will creak loudly if it is in
firm contact with anything and doesn't have room to move freely.

anything from heating to electric bikes - the source behind that web
site is a write for Home Power Magazine, Mother Earth News, and
others. You'll find detailed installation instructions for under floor
pex.
