Self-Regulating Heat Cable Splice – End-to-End Connection Kit
Product Overview
This heat cable splice kit allows secure end-to-end connection of self-regulating cable for pipe freeze protection and roof deicing systems.
What’s In The Box:
-
(1) Large Heat Shrink Tubing: The outer armor that seals the entire connection.
-
(1) Long Mastic Strip: The primary moisture barrier.
-
(2) Small Mastic Strips: For sealing the individual bus wire connections.
-
(2) Yellow Insulated Crimps: For securely joining the conductive bus wires.
-
(1) Copper Crimp: For maintaining ground braid continuity across the splice.
Extend Your Run. Repair a Cut. Do It Permanently.
Did you come up ten feet short on a roof line? Did a gutter cleaning accident slice your cable? Don’t scrap the whole run.
The Wasatch Heat Cable Splice Kit is the professional solution for connecting two pieces of self-regulating heat cable together. This isn’t a “twist-and-tape” fix. This is the exact industrial-grade splice kit we use on our trucks every day. When installed correctly, this connection creates a completely water-tight, electrically sound bond that is just as tough as the cable itself.
Why Pros Trust This Kit:
- Zero Water Ingress: Moisture is the enemy of heat cable. Our kit relies on high-grade mastic sealant and dual-wall adhesive heat shrink tubing to create a seal that stands up to standing water and freeze/thaw cycles.
- Mechanical Integrity: We don’t rely on soldering which can become brittle in the cold. We use heavy-duty crimps to ensure the electrical current passes through the splice without resistance or heat buildup.

🔥 Pro-Tips from the Field
Advice from Eric Wimmer to ensure your splice lasts 20+ years.
-
Stagger Your Cuts: Don’t cut both bus wires at the exact same length. Cut one about 1/2 inch shorter than the other on both sides of the cable. When you crimp them, the crimps won’t be right next to each other. This keeps the splice thin and prevents it from looking like a “snake that ate a rat” inside the gutter.
-
Heat Gun Required: Do not use a lighter or a torch. You need even, consistent heat to shrink the tubing and melt the adhesive liner inside. If you burn the tubing, you compromise the waterproof seal.
-
Test Before You Shrink: Always use an Ohm meter to check continuity after you crimp but before you shrink the tubing. It saves you from having to cut it all open if a crimp isn’t tight enough.
-
Stagger Your Cuts: Don’t cut both bus wires at the exact same length. Cut one about 1/2 inch shorter than the other on both sides of the cable you are joining. When you crimp them, the connectors won’t sit side-by-side. This keeps the splice thin (low profile) and prevents it from looking like a “snake that ate a rat” inside your gutter.
-
The “Tug Test”: After you crimp your wires, give them a firm tug. If they move, crimp them again. A loose connection is a fire hazard and the #1 reason splices fail.
-
Don’t Overheat: When shrinking the tubing, keep the heat gun moving. You want to see the sealant ooze out the ends slightly—that’s your visual indicator of a waterproof seal—but you don’t want to char the jacket.
🛠 Tools You Will Need:
This kit provides the parts, but you will need the following tools to complete the install:
-
Heat Gun: A lighter or hair dryer gets not hot enough. You need a heat gun to properly activate the adhesive lining in the shrink tubing.
-
Wire Strippers/Utility Knife: To carefully strip back the outer jacket and expose the bus wires.
-
Crimping Tool: A solid pair of crimpers to ensure the wires never pull loose.
⚠️ Critical Warning: Watch Your Lengths!
Just because you can extend the cable doesn’t mean you always should. Every heat cable circuit has a “Maximum Circuit Length” based on the voltage (120V vs 240V) and the amperage of your breaker.
-
Example: If your breaker can only handle 100 feet of cable, splicing an extra 50 feet onto an existing 80-foot run will trip the breaker.
-
Always check the spec sheet for your specific cable type to ensure the total combined length of the spliced run stays within safe electrical limits.

WHAT’S INCLUDED
- Drexan MultiTrace® Self-Regulating Cable (The gold standard for longevity)
- Factory-Terminated Power Plug (Grounded & Lighted) OR
- GFEP Factory-Terminated Power Plug (Grounded & Not lighted)
OTHER MATERIALS NEEDED:
- Aluminum Roof Clips: These corrosion-resistant clips are designed to hold the cable firmly in the “zig-zag” pattern on both asphalt shingles and metal roofs. Click Here
- M-1 Structural Adhesive: This is the only glue we trust. Unlike silicone that peels off in a year, M-1 creates a permanent chemical bond (up to 400 PSI) that cures even in damp or cold conditions. Requires a caulk gun. Click Here
How many Clips & Glue do I need? For a standard zig-zag or valley installation, a good starting point is to estimate 1 clip for every 24 inches (2 feet) of run.
- Note: This is an approximation based on typical roof layouts. Every project is unique, so don’t stress about getting the number perfect—you can always purchase extra clips or tubes of M-1 adhesive later if you find you need tighter spacing.
WHY CHOOSE A Heatcable.com ‘N’ PLAY KIT?
- Skip the Electrician: No hard-wiring required. These kits come with a pre-terminated, grounded power plug. Just mount the cable and plug it in.
- Instant Visual Check: The integrated Lighted Plug gives you instant peace of mind. One look tells you the system is powered up and melting snow. (Note: Actual plug brightness and color may vary).
VOLTAGE MISMATCH
WHY 120V MATTERS. DO NOT PLUG THIS 120V KIT INTO A 240V POWER SOURCE. HERE IS WHAT HAPPENS IF YOU DO:
The “Fixed Resistance” Danger: Old-school cables have a fixed resistance. If you double the voltage (by plugging into 240V), they get hotter and hotter until they burn themselves out or start a fire.
The Drexan Difference (Fail-Safe): Our self-regulating cable is smarter. If you hit it with 240V, it tries to generate 4x the power. However, because it is self-regulating, it senses that massive heat spike and fights to regulate it downward.
The Result: The cable wins the safety battle, but loses the war. The internal core is pushed beyond its limit trying to keep you safe. Instead of catching fire, it will simply “fail cold”—meaning the core degrades and will permanently stop producing heat.
Bottom Line: Plugging this kit into 240V won’t burn down your house, but it will ruin your cable and void the manufacturer warranty.
⚠️ CRITICAL WARNING
- It is recommended not to cut this cable. If a qualified technician cuts or modifies the cable for any reason, the warranty from Heatcable.com is immediately void. In this instance, the responsibility of the warranty falls entirely on the qualified technician performing the work. If you have excess cable, instead of cutting it, we recommend doubling it back into the gutter or downspout to increase melting power in that area.
- Code Compliance: Installation must strictly adhere to all applicable state and local electrical codes. We recommend consulting with a licensed electrician or your local building authority to ensure full compliance.
⚠️ INSTALLATION WARNING
Must be installed by a Qualified Electrician. To maintain the UL 508A Certification and ensuring the GFEP functions correctly, all input and output wiring must adhere to local, state, and national electrical codes.
✅ COMPATIBILITY CHECKLIST
Before you buy, confirm this kit fits your home:
- Voltage: 120V standard outlet (Verify your power outlet is 120V, not 240V).
- Gutter Type: Safe for Aluminum, Steel, and Copper gutters/downspouts.
- Outlet Proximity: Measure the distance from your roof edge to the outlet. You cannot use an extension cord. Ensure the kit length + lead is sufficient to reach the power source directly.
❌ INCOMPATIBLE / DANGER
To prevent fire, shock, or system failure, AVOID the following:
- NO EXTENSION CORDS: Never plug this kit into an extension cord. The resistance can cause overheating and fire. It must be plugged directly into a wall receptacle or controller.
- NO BURIED CABLE: Do not install this cable inside walls, under shingles, or buried in building insulation. The cable can be installed under our Patented Thermal Cartridge System.
- NO COILING: While Drexan cable is self-regulating, do not leave the cable coiled up in a tight spool while powered on. Unspool the cable completely before plugging it in to test.
⛑️ Important Safety & Specs:
- GFEP Protection: Safety is non-negotiable. If you do not select a kit with a built-in GFEP plug, the device must be used with a Ground-Fault Equipment Protected (GFEP) circuit.
- System Compatibility: The GFEP can also be applied in a custom or standard controller box, provided the controller already includes a GFEP component.
- Factory-Built Confidence: We don’t outsource our quality. These are assembled right here in Utah by pros who know winter.
TOOLS & TIPS
- Caulk Gun: Required for applying the M-1 Structural Adhesive. (We recommend a high-ratio “dripless” gun for easier application in cold weather).
- Extension Ladder: To safely access your roofline.
- Clean Rags & Isopropyl Alcohol: Essential for cleaning smooth surface areas—such as membrane and metal roofs—where clips will be glued. Any dust or grime left on the surface will cause the adhesive to fail.
- Light Duty Brush: Essential for brushing away loose granules and debris on asphalt shingle roofs before installing clips.
- Measuring Tape: To ensure consistent spacing for your “zig-zag” pattern.
- Pliers: Helpful for crimping the roof clips slightly if needed for a tighter hold on the cable.
🔥 PRO-TIPS FROM THE FIELD
- Don’t just install it—install it like a pro.
- The “Hershey Kiss” Method: When using the M-1 glue, don’t smear it flat like paint. Apply a nickel-sized dollop (shaped like a Hershey Kiss) under the clip. Press the clip down until glue pushes through the holes, but leave a layer of adhesive between the clip and the roof. This creates a chemical bond that lasts for decades.
- Create the “Melt Channel”: Remember, the cable doesn’t melt the whole roof; it creates a path for water to escape. Ensure your cable extends past the roof edge (1 inches or more) over the gutter to prevent an ice dam from forming right at the lip.
- Check Your GFEP: If you aren’t buying the GFEP plug option, you must plug this into an outlet protected by a GFEP breaker. We recommend testing the breaker before every winter season. Note: Your GFEP may also be in your controller.
- The “Drip Loop”: When plugging the unit in, make sure there is a small loop in the power cord below the outlet. This prevents water from running down the cord and directly into your electrical socket.
