Professionals in the commercial building market who are seeking innovative solutions to improve profitability, system performance and on-time project delivery are now looking to PEX as the design and installation solution for plumbing, heating and cooling applications that are designed to perform and last the life of the structure. With more and more engineers specifying PEX and more and more mechanical contractors installing it, PEX is quickly becoming the piping material of choice for hydronic heating and cooling systems.


This session will reveal the benefits of PEX for hydronic piping applications and explain the similarities and differences compared to metal pipe that are important to know when designing a system with PEX.

Topics will include:

  • PEX fundamentals
  • Design standards
  • Pipe sizing
  • Pipe routing
  • Expansion and contraction considerations
  • Design, layout and installation techniques
  • Case studies
