Vanex BPex Red (oxygen barrier) Tubing is designed specifically for radiant systems, including closed hydronic under-floor heating systems with ferrous components (cast iron boiler and pumps, geothermal systems, etc.) We also stock non-oxygen barrier Pex tubing and installation supplies. Vanex Pex and Vanex BPex conform to CTS-OD, SDR-9 and ASTM F 876/877 standards and are NSF-pw Potable Water Listed.
BPex (or Pex) tubing is generally spaced 6" to 16" on center in concrete slabs depending on the design temperature, heat loss, flow rate and several other factors. Most living areas require 6" to 8" spacing and most garages and basements require 10" to 16" spacing. Closer tubing spacing and shorter loop lengths allow for even heat distribution and helps minimize Hot-Spots and Cold-Spots due to excessive temperature drop in the loops. For 6" spacing, you will need 2 feet of tubing for every square foot of heated area, 8" spacing requires 1.5 ft per sq ft, 12" spacing requires 1 ft per sq ft and 16" spacing requires .75 ft per sq ft.
The absolute maximum loop length for 1/2" tubing is 400'. The recommended loop length is 290', or less (most loops are 100' to 250'). Shorter loop lengths work better because they provide less temperature drop in the loop. Hot-spots and Cold-Spots become very noticeable with longer loop lengths.

Tubing Installation Supplies:
Screw Clips (CLC3) and Nylon Tubing Zip Ties (HRCTMV100) secure Pex or BPex tubing loops prior to pouring concrete. Screw Clips install on the foam-board insulation to hold the tubing and the Zip Ties secure the tubing to the re-mesh or re-bar (tubing needs to be secured every 30"). Protective Elbow Sleeves (HRSL3) install wherever the tubing enters the concrete. The Protective Sleeve (HRCSL3) is used to protect the tubing at expansion joints and control grooves.

Note: Comap manifold and radiant package item numbers ending with "L" require a 1/2" crimp tool. Even though Radiant systems are very easy to install, we recommend installation by licensed, experienced professional installers. Radiant systems require electrical wiring, which must be comply with the NEC and other local electrical codes, if applicable. All electrical wiring must be preformed by a licensed electrician.
