What is an Uponor PEX plumbing system?

Uponor PEX plumbing systems for residential and commercial applications use crosslinked polyethylene (PEX) tubing instead of metal piping to distribute the water.

Is the same PEX tubing used for both PEX plumbing and radiant floor heating systems?

Answer
Uponor offers two types of PEX tubing — Wirsbo AQUAPEX® tubing and Wirsbo hePEX™ plus tubing. Wirsbo AQUAPEX® is used in plumbing and under certain circumstances in radiant floor heating systems. Typically, Wirsbo hePEX plus is used for radiant floor heating as it contains an additional layer on the tubing which acts as a barrier and reduces the amount of oxygen entering into the heating system.
