wort chiller-Pex tubing?

[bruno24]

I was thinking of making my own wort chiller out of Pex...what do you think?

from http://www.pexinfo.com/
"PEX tubing does not transfer heat as readily as copper, and so conserves energy."

so it would make a poor wort chiller when compared to copper.

Just gave my DIY copper chiller it's first work out - 200+ to 75 degrees in less than 15 minutes. Stick with the copper. You won't be sorry.
