This document is subject to updates. For the most current Viega technical literature please visit www.viega.us. Viega products are designed to be installed by licensed and trained plumbing and mechanical professionals who are familiar with Viega products and their installation. Installation by non-professionals may void Viega LLC’s warranty. -
Page 6: System Overview
These types of applications are not the most efficient kind of radiant heating compared to systems such as Viega Climate Panel and Viega Snap Panel, but deliver the comfort of having warm floors and full radiant heating throughout the house. Both methods utilize Viega Barrier PEX tubing and attach directly to the underside of the subfloor. -

The floor surface temperature will be 80°F with 25 BTU/h/ft output and 68°F room temperature. This chart shows the relation between room temperature and floor surface temperature for floor heating systems. Floor Surface Temperature Chart 10 of 40 IM-HC 530590 0621 Climate Trak (EN) -
Page 11: Calculating The Pressure Drop
4. Multiply pressure drop per foot by length of longest circuit. Example: GPM through ½” Viega Barrier PEX tubing: 0.7 GPM Pressure drop per foot: ~ 0.022 ft. of head / ft. Total pressure drop: 0.022 x 350 total ft. = 7.7 ft. of head... -

Page 16: Installing The Tubing
Climate Trak / Heat Transfer Plate System Installation 4.5 Installing the Tubing Begin to make non-stressful (teardrop) type loops for each of the bays, keeping loops small and manageable. Continue making the “teardrop” loops, being sure not to install any of the tubing into the Traks yet. -
Page 17: Post-Installation Tips - Insulation
Climate Trak / Heat Transfer Plate System Installation Continue transferring the tubing through the loops, finishing one bay at a time. 4.6 Post-Installation Tips - Insulation Insulation should always be used in a staple-up radiant installation. Ideally there should a 1" to 2" air gap in between the insulation and the Traks/ Plates. -
Page 18: Piping And Controls
In many applications either an Injection or Mixing Station can be used; Reducers however, because a staple-up system generally uses 10-20° higher water temperature, Viega recommends only using a Mixing Station with this type of application. Mixing Station includes: 2 - Ball valves 1 - Pump (low, medium, high) 1 - Diverting valve with integrated high temp. -

All schematics are conceptual. The designer must determine whether this application will work in the system and must ensure compliance with national and local code requirements.

Page 26: Pressure Testing
Before the finish floor is installed, the radiant system must be pressure tested. Air or water may be used as the medium. The following procedure is recommended by Viega. Check the local building codes for compliance or additional test requirements. -

Page 29: Finish Flooring
Vinyl flooring is another common choice for kitchens and baths and has a low R-value. Using carpet over radiant heating requires careful planning. Viega’s recommendation for a covering over a radiant system is to not exceed a total of a 2.5 R-value (the carpet pad plus the carpet itself). -
