Temp required to fix kinks in Wirsbo hePEX?
I know I can use a heat gun to fix kinks in Wirsbo hePEX, but it has me wondering what temperature is required (minimum) before the product starts to return to the original shape? Is that temperature higher than the published max temp ratings or possibly close to or a little lower than the published max temp ratings?
The guy I was working with today installing Wirsbo hePEX kinked it bad. I told him to flag it and we'd come back later to fix it. However, that didn't happen and the kink is now buried under sheet plates somewhere.
It just got me thinking, maybe running the radiant system at a high temp close to the max temps for the tubing might actually take some of the kink out naturally? Or is that just dumb thinking and high hopes?
After coming home and having a beer I realized I could have just used my lighter to fix the kink right then and there. Or so experimentation is showing me, anyway. Live and learn...
