Compare Radiant Edge PRO ice melt system to Company “A”
At a distance, all roof ice melt systems may look alike.
Just how does Radiant Edge PRO ice melt system compare?
- More energy efficient: Radiant Edge PRO ice melt system uses 33% LESS energy than Company A.
- Radiant Edge PRO circuits extend 50% FURTHER, so fewer home run circuits.
- Less heat is lost downward to roof deck: Radiant Edge PRO ice melt system has 72% LESS roof contact.
- Thin extrusion subject to warping: Radiant Edge PRO ice melt system is twice as strong.
- Higher percentage of heat to ice and snow: Radiant Edge PRO ice melt system has 45% MORE top surface area.
- More heat to ice and snow: Radiant Edge PRO ice melt system has 86% more convective surface area along the top edge of the panel
Why is Radiant Edge better?
Because WE follow
the FOUR SIMPLE RULES:
- Minimize heat lost downward to the roof deck due to surface contact.
- Maximize heat transfer from the heater cables to the top melting surface.
- Maximize heat transfer from the heater cables to the drip edge.
- Eliminate air gaps in the heat transfer path. Air is an insulator and the enemy of efficient heat transfer.
Problem: Drip edge. Inefficient Heat Transfer to Drip Edge. SUMMIT’S SOLUTION: Radiant Edge’s heater cable nests in a snug slot, and its massive profile promotes direct heat transfer to the drip edge to melt ice and snow. (Rules # 2, #3, and #4).
Thin Heater Walls: Less efficient heat transfer from cable to top surface. SUMMIT’S SOLUTION: Radiant Edge’s heavy heater slot walls (more than 65% thicker) maximizes heat transfer from cables to the top melting surface. (Rule #2)
Problem: Loose Slots : Air space in slots means less thermal contact and less efficient heat transfer. SUMMIT’S SOLUTION: Radiant Edge’s heater slot clearance is only .010″. This super-snug fit around the cable conducts heat better by eliminating insulating air gaps. (Rules #2, #3 & #4)
Problem: Electrolysis Risk With Dissimilar Metals: Contact between the aluminum base and a copper cover will eventually corrode due to electrolysis. SUMMIT’S SOLUTION: Summit has a proprietary isolator coating that prevents contact between the dissimilar metals.
Problem: Inefficient Top Heater: Minimal heat is transferred from top heater to the top surface and up roof. SUMMIT’S SOLUTION: Radiant Edge maximizes efficient transfer of heat to the top surface and the convective fin to distribute heat across a 45% larger top surface area than Company A. The fin provides 86% more convective surface area to better distribute heat up the roof to melt ice and snow. (Rule #2)
Problem: Excess Roof Deck Surface Contact: Excessive roof contact area loses heat drawn into the cold overhang below. SUMMIT’S SOLUTION: Radiant Edge has 72% LESS roof deck contact. Every feature has been engineered to minimize heat loss and maximize heat transfer to the ice melting surfaces. The result is less energy needed = less operating costs. (Rule #1)
Problem: Fastener Slot: Burrs from pre-drilling are created on the bottom surface can damage roof membranes that cause leaks. SUMMIT’S SOLUTION: Radiant Edge cleverly raises the slot where fasteners are driven. No pre-drilling or deburring of holes is required. This feature eliminates roof leaks and minimizes roof deck surface contact (Rule #1). Radiant Edge also includes specially coated super-duty #14 screws which are compatible with aluminum. Their waterproof gaskets prohibit moisture from tracking down the screw shank and leaking. Company A specifies you furnish your own “Outdoor Screws.”
Problem: Three Heaters Required: Company A’s panel requires 50% more heat and energy to perform. Excessive heat loss downward and low cross section makes their’s need more heat to melt the ice and snow. SUMMIT’S SOLUTION: Every feature of Radiant Edge is designed to minimize heat loss and maximize heat transfer to the melting surfaces. Radiant Edge uses just two heaters to get the job done so it costs much less to install and operate. Radiant Edge conveniently has an auxilliary slot for a return raceway if needed.
Problem: Thin Top Surface. Low cross section means less efficient heat transfer to melt ice and snow. SUMMIT’S SOLUTION: Radiant Edge’s top surface is 100% thicker than company A’s resulting in better heat conductivity. (Rule #2)
