Is PEX okay for h/w-radiator heating system?
Can PEX piping be used for a cast iron hot water radiator heating system?
Right now, the system is a combination of original galvanized steel pipes and more recently added copper lines. I am just wondering if when moving the location of a couple of the radiators for a remodel job, can I use PEX to reconnect the radiators at their new locations? |

I've seen PEX used to supply hot water to wall heaters in new construction. This obviously passed inspection in Seattle. O.P. - contact your local inspector for the final word. Bob |

Some have a temperature limit below what your radiator may be. |

Yes, many hybrid hydronic systems are using PEX. they are running at 180F, so no reason you couldn't. I would want to verify the specs on the pex tubing though. |

Hydronic or floor heat is around 110f not the 185 my boiler gets to, You risk loosing your boiler to a fancy garden hose. But its your house not mine. |

Thomas A. Edison And the site did say 140f for saftey, for a reason, plastic has failed. 140f would not get me through a winter without being cold. Boilers can run at 190-200f safely, aquastats go bad. Plastic pipe is is just not safe at high temps for the long term. Also his system pressure must be figured in. |

The Wisbro/Uphonor and Zurn pex's are rated at 200 degrees and 80 psi. Pex is approved by code for hydronic radiator systems in many areas. I Vanex PEX - 160 psi @ 73°F and 100 psi @ 180°F. From the data sheet:* * Vanex tubing can also be used in "continuously-recirculating" plumbing systems at temperatures of up to 140° F while still maintaining excellent chlorine resistance. For information on the suitability for other hot and cold water applications not listed here, consult with your Vanguard Piping Systems representative. |

I don't understand the comment about underfloor heating running at a different pressure. It typically uses 12 PSI just like other hot water heating systems. PEX has been in use for over 50 years.

I am currently a Colorado Master Plumber and I have been a plumber for more then 35 years. I have installed miles of PEX pipe. Like all pipe it has a number rating on it. It should have a temperature rating on it. If it has a temperature above 160 then it is OK for hot water heating. |
