1/2" oxygen barrier PEX is the most common size for all residential and light commercial radiant heating applications. It's commonly used for heating concrete slabs in basements, garages, warehouses, manufacturing and other facilities. It is also the most common oxygen barrier PEX size for staple-up installations (between joists - with and without the aluminum heat transfer plates) and sandwich type installations (between subfloor and finished floor).
Typical circuit length of 1/2" oxygen barrier PEX tubing is anywhere between 300ft and 350ft, depending on the design and radiant heating system requirements.
For snow melting applications, maximum recommended circuit length is 200ft.
Q: What is the typical testing pressure for an in-slab installation?
A: For all types of radiant heating projects, typical testing pressure is 100 psi for a duration of at least 30 minutes. Local codes may vary, so it's best to consult with a professional installer in your area.
