The best pipe for the job

Learn about Uponor’s two different PEX piping products for residential radiant floor heating systems.

Uponor residential radiant floor heating system piping products

Uponor offers two different piping types for residential radiant floor heating systems: Wirsbo hePEX™ and Uponor helioPEX™ X2. Both pipes are flexible, durable and feature an oxygen barrier to protect the ferrous components in a hydronic radiant system — a must for any radiant project.

Choose the right pipe for your radiant project

With 40 years of proven performance, Wirsbo hePEX is Uponor’s premium PEX-a pipe available in various sizes from 5/16" to 4". Uponor helioPEX is a “PEX-other” crosslinked polyethylene pipe that allows greater profitability in projects using pipe sizes from ½" to ¾".

Uponor PEX piping vs. other radiant piping products

Uponor PEX piping products feature the highest degree of crosslinking for the greatest flexibility and durability. And unlike PEX-b, PEX-c and PE-RT pipe, Uponor pipe can be kink repaired with a simple shot of heat from a heat gun to eliminate unnecessary couplings in a system. Best of all, Uponor PEX pipe offers thermal memory, which enables the strongest connections for ASTM F1960 expansion fittings.
