You need to be aware that your collector loop is pressurized and
likely contains glycol, and because of this, it can develop
temperatures much hotter than the boiling point of water.  A 300F
slug of hot pressurized glycol will be the death of your PEX.  Also,

think it is a wonderful material in the correct application), it is
plastic, and as such, it will rapidly loose strength when it gets too
