With the Staple-Up panel on the left and Warmboard on the right, the differences in performance are abundantly clear. Within 20 minutes, Warmboard has achieved a panel temperature of 70º F and has output 10 BTUs per sq ft. Staple-Up was unable to reach this temperature or BTU output within 2 hours. At 20 minutes the Staple-Up has output 1 BTU per sq ft.

The striping (the temperature variation across the surface of a panel) only varies by 2.1º F on Warmboard while Staple-Up was double at 4.1º F. Warmboard is also generating 16 BTUs/HR/SF (British Thermal Units per hour per square foot), while Staple-Up produces on 4. This means Warmboard uses energy 4x more efficiently than Staple-Up; good news for your monthly energy bills.

Tubing on the Warmboard panel is 12” apart. Staple-Up tubing is at 8” increments. This means more tubing and manifolds are added to the Staple-Up 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.
