Heat Trace & Freeze Protection Cable

For decks adjacent to gutters or downspouts, pairing the deck pan system with GutterMelt keeps the full drainage path clear — meltwater from the heated deck needs to flow freely through gutters and downspouts to the ground. GutterMelt is recommended wherever deck meltwater drains into a gutter system.

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.

Yes. GutterMelt SR cable is safe for use with plastic downspouts because of its self-regulating heating characteristics — the cable cannot overheat, since its heat output decreases as the surrounding temperature rises. This makes it safe on materials that would be damaged by a constant-output cable running too hot in warmer conditions.

Yes. GutterMelt is ETL listed for the United States and Canada, certified to UL and CSA standards.

GutterMelt cable sold per foot carries a 10-year manufacturer’s warranty. Pre-configured cordset kits carry a 5-year warranty. The difference comes from the kit’s added components — the factory termination and LED plug — which have a shorter rated service life than the heating cable itself. The cable in both versions is identical; the warranty difference reflects the additional hardware required to make the kit plug-and-play.

GutterMelt sold per foot is bulk cable cut to the length specified for the project, intended for custom installation by a contractor or electrician. GutterMelt kits are pre-configured, ready-to-install cordsets that come factory-terminated with a 6-foot power cord and LED plug, along with downspout hangers and roof clips, in standard lengths from 10 to 130 linear feet. The kit format trades custom sizing for plug-and-play simplicity — ideal for straightforward residential installations.

GutterMelt is Heatizon’s heat trace cable for gutters, downspouts, eaves, and drains — designed to maintain a clear water flow path and prevent ice dam formation. It’s available in Self-Regulating (SR) and is ETL listed to UL and CSA standards for the United States and Canada. GutterMelt operates at 120V, 208V, 240V, or 277V and can be ordered by the foot for custom installations or as a pre-configured, ready-to-install cordset kit.

Yes. Installing pipe insulation over Outpipe cable significantly reduces the energy required to maintain the pipe temperature — the insulation limits heat loss from the pipe surface to the surrounding air, allowing the cable to work more efficiently. Without insulation, the cable must work harder to compensate for continuous heat loss, increasing energy consumption. The type and thickness of insulation depends on pipe diameter, ambient temperature, and the desired maintenance temperature.

Yes. Outpipe is rated for outdoor installation — protecting exposed exterior pipes, outdoor valve stations, and unheated structures such as barns, garages, and outbuildings where pipes are at risk of freezing. The ETL listing covers outdoor applications.

Outpipe cable is wrapped or run longitudinally along the pipe surface and secured with fiberglass tape at regular intervals. For freeze protection only, a single cable run along the bottom of the pipe is typically sufficient. For temperature maintenance at higher heat loss rates, a spiral wrap or multiple longitudinal runs increase watt density per linear foot of pipe. The pipe is then insulated over the cable to minimize heat loss and reduce energy consumption. Bulk cable is connected to the electrical supply by a licensed electrician; kit versions plug into a GFCI-protected 120V outlet.

Outpipe is used for four primary pipe heating applications. Pipe freeze protection maintains water and fluid lines above freezing point during cold weather. Pipe temperature maintenance keeps process fluids at a specific operating temperature regardless of ambient conditions. Valve freeze protection keeps valves and actuators operable in cold environments where ice can prevent valve movement. Tank heating maintains the temperature of storage tanks holding fluids that would freeze, thicken, or degrade below a minimum temperature.

The difference is the added kit hardware — the factory termination and plug — which have a shorter rated service life than the heating cable itself. The SR cable inside the kit is identical to the bulk SR cable with the 10-year warranty. For permanent installations where long-term performance is the priority, bulk cable terminated by a licensed electrician carries the full 10-year warranty. For plug-and-play residential applications where convenience is the priority, the kit format offers a practical, ready-to-install solution at the 5-year warranty tier.

Each Outpipe kit includes self-regulating heating cable factory-terminated with a 120V power cord and plug, fiberglass tape for securing the cable to the pipe, and a complete installation and instruction guide. The kit format is designed for straightforward residential and light commercial pipe freeze protection — plug-and-play without any field splicing or electrical panel connection.

Pre-configured Outpipe 120V kits are available in 11 standard lengths: 5, 10, 15, 20, 25, 30, 35, 40, 60, 80, and 100 linear feet. Each kit includes the self-regulating heating cable factory-terminated with a power cord and plug, plus fiberglass tape and installation instructions. Kits are ready to install — no electrical connection beyond plugging into a GFCI-protected 120V outlet required.

Outpipe SR cable produces 5, 9, or 12 watts per linear foot at 50°F depending on the watt rating selected. MI cable produces up to 24 watts per linear foot. Pre-configured 120V kits use SR cable rated at 5 watts per foot. The correct wattage for a project depends on pipe diameter, ambient temperature, insulation thickness, and the fluid being protected — contact a Heatizon distributor for guidance on the right wattage for the specific application.

Choose MI Outpipe for large commercial and industrial pipe heating applications where consistent, high watt output is required across long runs — process pipes, industrial fluid lines, and large tank heating where the SR cable’s maximum output is insufficient. The MI variant is ordered to exact length before installation. Choose SR bulk cable for most residential and light commercial freeze protection applications where the SR variant’s self-regulating characteristics provide built-in energy efficiency and plastic pipe safety.

Self-regulating Outpipe cable automatically adjusts its heat output based on the temperature of the pipe surface it is wrapped around — producing more heat when the pipe is cold and less as the pipe warms. This means the cable cannot overheat and is safe for plastic pipe materials. Because output varies with temperature along the cable’s full length, a single SR cable can protect a pipe that passes through varying ambient conditions — from a warm indoor section to a cold exterior section — without any additional controls or zone management.

Yes. Outpipe SR cable is safe for plastic pipes because of its self-regulating characteristics — the cable automatically reduces its output as the pipe temperature rises, preventing overheating that could warp or damage plastic pipe materials. Outpipe is compatible with both plastic and metal pipe types including PVC, CPVC, PEX, copper, and steel.

Outpipe bulk SR cable and MI fixed-length cable carry a 10-year manufacturer warranty. Pre-configured 120V kits carry a 5-year warranty. The difference comes from the kit’s added components — the factory termination and plug — which have a shorter rated service life than the heating cable itself. The cable in both formats is identical; the warranty difference reflects the additional hardware that makes the kit plug-and-play.

Yes. Outpipe is ETL listed for the United States and Canada across all three formats — bulk SR cable, MI fixed-length cable, and pre-configured 120V kits. ETL listing is issued by Intertek, an OSHA-recognized Nationally Recognized Testing Laboratory carrying equal legal standing to UL and CSA listings in the United States.

Outpipe and GutterMelt share the same fundamental cable construction and the same three formats — bulk SR cable, MI fixed-length cable, and pre-configured 120V kits. The difference is application. GutterMelt is designed for gutters, downspouts, and roof eaves. Outpipe is designed for pipes, valves, and tanks. Both are ETL listed for US and Canada, carry a 10-year warranty on bulk and MI cable and a 5-year warranty on pre-configured kits, and use the same self-regulating technology that prevents overheating on temperature-sensitive materials.

Outpipe is Heatizon’s heat trace cable for pipe freeze protection, pipe temperature maintenance, valve freeze protection, and tank heating. It is available in three formats. Bulk self-regulating (SR) cable is sold by the foot, cut to length in the field, and available in 120V, 208V, 240V, and 277V. MI (mineral-insulated) fixed-length cable is ordered to exact project length and delivers higher watt output for demanding commercial and industrial pipe heating applications. Pre-configured 120V kits come factory-terminated with a plug, ready to install, at 5 watts per foot in standard lengths from 5 to 100 linear feet. All three formats are ETL listed for the United States and Canada.
