epdm vs. pex tubing

[mjfnff]

I am trying to decide between epdm and pex tubing for radiant heating. Less than 30 psi and 180F. Any advise on pros and cons with respect to life expectancy greatly appreciated.

mjfnff,

Both materials should work fine.
Although it is my belief that you will get more radiant heat transmission from the PE tubing.
