Q: What exactly is PEX?

A: PEX is an acronym for crosslinked polyethylene. There are three different types of PEX tubing: PEX-a, PEX-b and PEX-c. Uponor manufactures PEX-a tubing, which is considered the superior type of PEX in the plastic pipe industry. This is due to the level of crosslinking in PEX-a tubing that creates a more flexible product that offers thermal and elastic memory for greater durability and workability.


Q: How does hydronic radiant floor heating and cooling work?

A: In an Uponor commercial radiant floor heating and cooling system, warm or cool water flows through flexible, durable PEX tubing that is embedded under the floor. The PEX tubing carries the water into designated areas, also known as zones, and radiates up from the floor to warm or cool people and objects in a room.


In other words, in radiant heating applications, the energy moves away from the heated surface towards the cooler area; for radiant cooling, the energy moves towards the cooled surface from the warmer area.


An Uponor commercial radiant heating and cooling system was installed in the Pier 15 Exploratorium. Watch the video below to learn more about the project.

Q: How can an Uponor PEX radiant heating and cooling system be both comfortable and efficient?

A:  Water has the capacity to transport energy 3,500 times greater than air, which allows a hydronic radiant heating and cooling system to provide greater comfort to a space using less energy than forced-air systems.
