There are actually 3 types of copper, and even the lowest grade (Type M) has a working pressure of 326 PSI @ 250F, even if that was the stuff I was going to use it would work. The question was never the rating, durability or strength of the copper but the heat transfer comparison to black iron pipe. My original intent was to use black iron; however after talking with a friend of mine about what he has plumbed shops around here locally with and pricing out the final system with copper being the less expensive solution, I chose copper.
