Hydronic Piping with PEX: Pros and Pitfalls!

For our upcoming meeting, Distinguished Lecturer Devin Abellon will be presenting on Hydronic Piping with PEX.


While the use of crosslinked polyethylene (PEX) piping has been widespread in residential applications for some time, building owners, contractors and engineers are moving towards it as a cost-effective and flexible alternative to conventional metallic piping systems on large-scale commercial projects. PEX has become a proven system solution that can reduce both material and labor costs while providing the reli­ability and peace of mind that building owner’s demand. When considering PEX, however, it is important that contractors and engineers understand not only the benefits but the challenges and potential pitfalls. 

This seminar will examine the following:

  • What is crosslinked polyethylene (PEX)?
  • What are the different types of PEX available in the commercial marketplace?
  • What are the advantages of PEX compared to conventional metallic systems?
  • How does a PEX design differ from a metallic pipe design?
  • What are common design and installation best practices?


The Tri-County chapter is eager to get its members more involved with ASHRAE. We not only want to improve our monthly attendance, but we want to share some leadership opportunities with you within our chapter. We want you!

Do you have any ideas on how we can improve our chapter?

Are you able/willing to volunteer (become an officer) to make our chapter great again?

Is there anything that prevents you (or people that you may know) from coming to our meetings/events?


Former Tri-County officers (past presidents, board of governors, etc...) as well as Region X leaders/officials will be attending to this meeting. They will be there to answer any question you may have about ASHRAE and will be providing past/current experiences while volunteering in ASHRAE. We want you to realize the great impact and true value of your involvement with ASHRAE!

Our Chapter was born 31 years ago, and we are willing to do what it takes to make it great yet again! Are you with us?

Come to our meeting, join the family!
