Uponor/Wirsbo Radiant Systems

Uponor Radiant Floor Heating has existed for more than three decades. They've been making the PEX tubing used in their radiant floor heating systems since 1970, longer than any other PEX tubing manufacturer. PEX (crosslinked polyethylene) tubing is a specially designed plastic tubing with distinctive properties that make it ideal for radiant floor heating and plumbing systems. Uponor produces PEX-a tubing, which is considered the superior type of PEX.

A hydronic radiant cooling system is an installation of embedded tubes or surface mounted panels that are designed to absorb and remove energy from a space, 50% to 80% of which is radiant energy. Just as in heating, a radiant cooling system uses the structure and surfaces of an area to transfer energy. A floor cooling system should primarily be used where the system also will be used for heating in winter.
Design a radiant heating/cooling system to maximize the cooling capacity.

Uponor PEX carries the following hydrostatic temperature and pressure ratings: 

  • 200°F at 80 psi
  • 180°F at 100 psi
  • 120ºF at 130 psi (1/2" Wirsbo AQUAPEX tubing only)
  • 73.4°F at 160 psi
