A GutterMelt kit includes the heating cable with a factory-attached 6-foot power cord and LED plug, downspout brackets, roof clips, a complete installation and instruction manual, and access to Heatizon’s technical support team.

Yes. GutterMelt cable and kits can be installed in existing gutters and downspouts without modification to the gutter system itself. The cable is secured using hangers and clips designed for the installation, making it a straightforward retrofit for homes and buildings experiencing ice dam or gutter freezing problems.

GutterMelt is recommended for use in conjunction with a roof deicing system such as ZMesh or Tuff Cable in Invizimelt. GutterMelt protects gutters and downspouts, but meltwater coming off a roof still needs somewhere to go — pairing GutterMelt with an under-roof or surface deicing system ensures water has a clear path off the building rather than just clearing the gutters in isolation.

GutterMelt can be thermostatically controlled, hard-wired, or sensor-controlled, depending on the installation. For larger commercial projects, Heatizon offers a variety of relay panels that allow multiple circuits to be controlled from a single activation device. Automatic sensors that detect moisture and temperature are the recommended activation method for energy efficiency — the system only runs when conditions require it.

GutterMelt kits include downspout hangers and roof clips for straightforward installation in gutters, downspouts, and along roof eaves. Bulk GutterMelt cable is installed by a contractor or electrician according to a project-specific layout, typically run in a zigzag pattern along the eave and straight down through downspouts and drains. Cable can be cut to length in the field for custom runs.

GutterMelt’s cable construction is engineered to prevent water wicking along the length of the cable — a common failure point in lower-quality heat trace cables where water travels along the cable jacket and causes internal damage or shorting over time. This construction detail contributes directly to GutterMelt’s industry-leading warranty length.

Pre-configured GutterMelt kits are available in standard lengths of 10, 30, 50, 70, 90, 110, and 130 linear feet. GutterMelt sold by the foot can be cut to any length required for the project, giving installers flexibility for non-standard gutter and downspout configurations.

GutterMelt is available in 120V, 208V, 240V, and 277V configurations. Pre-configured kits are sold in 120V with a factory-attached plug; bulk cable sold by the foot is available across the full voltage range for custom commercial and residential installations.

GutterMelt SR cable produces 5, 9, 12, or up to 24 watts (CW version only) per linear foot at 32°F in snow and ice conditions, depending on the wattage rating selected for the project. Heatizon’s design team specifies the correct wattage based on climate, gutter/downspout size, and the specific freeze protection requirements of the installation.

Constant Wattage GutterMelt produces a fixed heat output regardless of ambient temperature, unlike the self-adjusting SR version. It’s typically specified for longer cable runs or larger commercial systems where consistent, predictable wattage across the entire length is required for accurate system design. Both SR and CW versions are listed to UL and CSA standards and carry Heatizon’s standard warranties based on per-foot vs. kit purchase.
