Hi all, I want use PEX-AL-PEX tubes for antifreeze liquid which goes from solar collectors to heat-exchanger. But not sure if this material is fine for that. Has alumunium corrosion problems with antifreeze liquid? Or any others?
This material is not rated for the temperatures delivered by the solar panels. Only copper or stainless steel linesets should be used. The Pex piping will be compromised by the high temps and fail prematurely.
