Constant Wattage Heating Cable for Roof & Gutter De-Icing - Medium Temp, Durable
Shandong Huaning's Constant Wattage Heating Cable delivers reliable winter protection for commercial buildings. Engineered specifically for roof edges and gutter systems, this medium-temperature cable automatically prevents ice dam formation and gutter blockages. Its self-regulating technology maintains optimal 65°C surface temperature while offering energy-efficient operation—critical for reducing structural damage risks and maintenance costs throughout harsh winters.
Key advantages include:
- ✅ Durable fluoropolymer construction resists UV degradation and chemical corrosion
- ✅ Precision thermal output (8-10W/ft) eliminates under/over-heating issues
- ✅ Self-regulating feature adjusts power based on ambient temperature
- ✅ UL-certified safety compliant with US/Canada electrical standards
| Model | Voltage | Power Output | Max. Length | Temp. Range |
|---|---|---|---|---|
| CWHR-M-120 | 120V | 8W/ft | 150ft | -40°C to 65°C |
| CWHR-M-240 | 240V | 10W/ft | 300ft | -40°C to 65°C |
Installation flexibility allows customization for:
- ❄️ Eaves and valleys where ice dams typically form
- ❄️ Gutters and downspouts prone to snow accumulation
- ❄️ Drain pipes and roof drains requiring freeze protection
The cable's braided metal shield provides mechanical protection against abrasion during severe weather, while its constant wattage technology ensures uniform heating across the entire length—unlike cheaper resistive cables that lose efficiency over distance.
Pro Tip: Combine with our HNT-100 thermostats (sold separately) for automated temperature-triggered operation, reducing energy consumption by up to 40% compared to continuous-run systems.
Choose this solution for long-term infrastructure protection that minimizes:
- 🛑 Roof collapse risks from ice weight accumulation
- 🛑 Water damage from backed-up gutters
- 🛑 Emergency repair costs during winter storms
Frequently Asked Questions
Q: Can this cable be installed on metal roofs?
A: Yes, the fluoropolymer insulation withstands direct contact with metal surfaces. For corrugated metal roofs, use mounting clips every 12 inches.
Q: How does it perform during power outages?
A: The cable requires electricity to operate. We recommend backup generators for critical infrastructure. The system draws 8-10W per foot during active heating.
Q: Is professional installation required?
A: While DIY installation is possible for small sections, commercial applications require certified electricians for NEC compliance and warranty validation.
Q: What maintenance is needed?
A: Annual visual inspections are recommended. Clear debris from gutters before winter. The cable itself is maintenance-free with a typical lifespan of 15+ years.
Q: Can it be used on PVC gutters?
A: Absolutely. The surface temperature stays below PVC deformation thresholds. For optimal performance, secure cables with adhesive-backed mounting tape.
