That's interesting to know about solar hot water.  It's one of the
applications I am plannning on.  I'd like to know more if you can dig it
up.  Solar collectors can get very hot - perhaps it pushes the maximum
temperature?  Esp if you are using a glycol loop, which can get above
212F without boiling?

We used the PEX system in a recently built house.  I believe every
positive thing Lawrence has to say about it is true (chlorinated water
is not a problem).  But be aware there are several 'systems' 
out there and the tools required to compress the rings (to hold the
fittings together) are proprietary to the specific system.  PEX tubing
comes in several sizes btw.  I gather it can not be used for solar hot
water because it won't expand properly.  Let me know please if I'm wrong
about this latter point.  Sacie Lambertson
