What type/brand of PEX?

Patchogue Phil_29

What kind or type of PEX should I use for baseboard heating i.e. interconnecting copper fintube from room to room or making homeruns from fintube to the boiler?

Operating temps to 180* maximum. Should teh PEX be able to stand 200* to be safe?

PEX AL PEX? Other ???

Brand(s) that are good? Brand(s) that I should avoid?

TIA,
Phil

Definitely use PEX-AL-PEX. It expands less, but remember it does expand so with high temperature delta-T's and longer runs, use expansion loops!

Lots of good brands out there.

PAP all the way

I've used Wirsbo MultiCor without any problems, also Kitec. I recently tried the Viega FostaPex, it has an extra PE outer layer and full size pex inner tube. Seems very durable, especially for slabs.

I like the new crimp fitting offered by Wirsbo and Viega. A sturdy, good looking stainless ring. The white tube is the Wirsbo.

Wirsbo and Rehau are a couple brands that I like. It should be PEX A (aka Engel Pex). There are three ways to accomplish the cross linking thus A/B/C Pex. The PexA has the highest percentage of cross linking and therefore is stronger and more flexible.

If you use regular PEX to feed high temp baseboards.. make sure you're calculating for and accomodating expansion!! 1.1"/10deg temp rise/100 feet. racks up fast!
