    Default pex and steam heat

    I have a steam boiler I want to put another zone in my basement .I put a ciculating pump on The pex that I bought has an oxygen barrier and is for base board heat HOWEVER I just noticed that it is rated for 180F and I am sure that my steam boiler puts the water hotter than that IS there a PEX rated for steam???

    Are you using a heat exchanger? If not then all your piping must be well below the water level in the boiler.

    Short answer is no, you can't use pex.
