System Overview
6 of 40 IM-HC 530590 0621 Climate Trak (EN)
1. Heavier aluminum than the Heat Transfer Plates
2. Fastest installation time (does not require Groove Tube)
3. Easiest to install (Traks and tubing are installed separately, so there is
no struggling with the tubing while the fastening is being done)
4. Predrilled holes for ease of fastening with screws
5. Comes in 4' or 8' long Traks that also help with installation time
6. Snap-in groove for tubing maximizes contact between the aluminum
and the PEX Tubing for e󶈷cient heat transfer
In the following pages, you will be guided through the system design,
layout, installation, and start-up of the Climate Trak System.
Climate Traks and Heat Transfer Plates are designed for retro󶈵t
applications or in applications where the buildup above the sub󶈶oor is
a concern. These types of applications are not the most e󶈷cient kind of
radiant heating compared to systems such as Viega Climate Panel and
Viega Snap Panel, but deliver the comfort of having warm 󶈶oors and full
radiant heating throughout the house. Both methods utilize Viega Barrier
PEX tubing and attach directly to the underside of the sub󶈶oor. This is a
fast, lightweight application to install and provides the comfort of radiant
heat the homeowner is looking for.
2 System Overview
2.1 Application Bene󶈵ts
2.1.1 Climate Trak
1. Made from thinner, more 󶈶exible aluminum than the Climate Traks
2. Comes in 20" long by 5" wide plates
3. Requires a small bead of Groove Tube down the channel where the
tubing is run right before installation
2.1.2 Heat Transfer Plates
Systems should be protected from freezing at all times.
Proper insulation or glycol mixture may be needed in system
if not used for an extended period of the heating season.

1. Calculate the total heated area.
2. Using the charts on the previous page and the total area, calculate
the total number of Traks/Plates and amount of tubing needed for the
job.
3. Using the circuit length chart, calculate the total number of circuits
needed.
Example: Heated Area - 1,500 sq. ft.
Calculating Number of Traks:
8 ft. Climate Traks 8" O.C.
# of Traks = 1,500 sq. ft. x .18
# of Traks = 270
- Sold in packages of 20:
(round up to order 14 boxes)
Calculating Amount of Tubing:
Amount of Tubing = 1,500 sq. ft. x 1.7
Amount of Tubing = 2,550 ft.
Calculating Number of Circuits (≤25 BTU/ft2):
Amount of Tubing = 2,550 ft.
2550 ft./400 ft. = 6.375
# of 1/2” circuits = 7

3.3 Calculating the Supply Water Temperature
1. Locate desired BTU output (from Radiant Wizard) on left vertical axis.
2. Follow to the right until you reach the selected total R-value curve.
3. Then move down to the horizontal axis and read the supply water
temperature.
(For additional Climate Trak/Heat Transfer Plate BTU output charts, refer
to Appendix E).

3.4 Calculating the Floor Surface Temperature
1. Locate desired output (from Radiant Wizard or other source) on left
vertical axis.
2. Follow to the right until you reach the curve.
3. Then move down to the horizontal axis and read the ∆T between the
room temperature and the 󶈶oor surface temperature.
4. Add the room temperature and the ∆T to get the 󶈶oor surface
temperature.
Example:
Output needed: 25 BTU/h/ft2
Room temperature: 68°F
Temperature ∆T (from chart): ~ 12°F
Floor surface temperature: 68°F + 12°F = 80°F
The 󶈶oor surface temperature will be 80°F with 25 BTU/h/ft2 output and
68°F room temperature.
This chart shows the relation between room temperature and 󶈶oor surface
temperature for 󶈶oor heating systems.
