I am running some pex piping to a couple of hot water radiators. I can't find any info on the temp. limit for the poly fittings - are they OK to use on the heating system piping or only for potable systems? Thanks.

    What fitting brand?
    The uphoner fittings are ok for heat. I am not sure about all brands.

    I wouldn't even use poly fitting for domestic.... unless its Uponor (cold-expansion joints).

    I've had 0 issues with Uponor or Viega EP fittings for heat.
