20 minutes after the test has begun, Warmboard has achieved a panel temperature of 70º F. Quik Trak is able to reach this temperature after 1 hour 20 minutes.
The striping (the temperature variation across the surface of a panel) only varies by 2.1º F on Warmboard while Quik Trak is at 4.9º. After 2 hours, Warmboard was generating 16 BTUs/HR/SF (British Thermal Units per hour per square foot), while Quik Trak produced only 10. This means Warmboard is using the energy you pay for more effectively.
Tubing on the Warmboard panel is 12” apart. Quik Trak tubing is at 7” increments. This means more tubing and manifolds are added to the Quik Trak cost as well as longer installation time.
Both panels were in an environment with a 65º F air temperature. They both also had the same water temperature, 120º F. The insulation over each panel had a R-Value of 2.22.
Note: Temperatures were taken from just above the center of each panel. Striping differences were also gathered from this area. Temperatures from on top of the tube were compared to temperatures at the midpoint between the tubing pattern.
