FAQ
How does the self‑regulating feature work?
The cable contains a sensor that reduces power as the surrounding temperature rises, preventing overheating and saving energy while still melting ice.
Can I install the cable myself?
Yes, the kit includes mounting clips and a step‑by‑step guide. Remove old de‑icing devices, clean the gutter, and attach the cable following the instructions.
What length should I purchase?
Measure the total linear footage of your gutters and downspouts. Our SKUs range from 60 ft to 105 ft, allowing you to select the exact length needed.
Is the cable safe for use near trees or vegetation?
The PE outer layer is non‑flammable and safe for installation near non‑combustible surfaces. Keep a clearance of at least 2 inches from vegetation to avoid heat exposure.
What warranty does SnulyHeet provide?
All heat cables come with a 2‑year limited warranty covering manufacturing defects and performance issues under normal use.
