Industrial Precision. Residential Safety.
Stop burning money on 24/7 heating. You wouldn’t run your air conditioning with the windows open, so why run your heat cable when it’s 50°F outside? Our Single Circuit GFEP Controller is the “brain” your system needs. It combines industrial-grade switching, precise temperature control, and critical safety protection into one pre-assembled, UL-certified box.
🏭 CERTIFIED UL 508A PANEL SHOP
We don’t just “build boxes”—we engineer solutions. Wasatch Heat Cable is a Certified UL 508A Panel Shop. This distinction matters. It means this isn’t a garage DIY project; it is a professionally engineered control panel built to rigorous national safety standards. Every unit is assembled, wired, and tested in-house by certified technicians to ensure it meets the same quality benchmarks as industrial factory controls.
WHAT’S UNDER THE HOOD?
This isn’t a cheap plastic timer. We use components that professional electricians trust.
-
1x Nader GFEP Circuit Breaker: We don’t rely on standard breakers. We utilize Nader industrial-grade Ground-Fault Equipment Protectors. This critical component constantly monitors your cable for current leakage (shorts), instantly cutting power if a fault is detected to prevent fire or shock. Note: This built-in protection saves you from buying an expensive GFEP breaker for your main panel.
-
Precision Thermostat (T-Stat): The integrated thermostat ensures your system only runs when it needs to. Set your activation temperature (typically 38°F), and the system handles the rest—turning on when the freeze sets in and shutting off when the sun comes out.
-
External LED Indicator: No more guessing. The high-visibility LED light on the door gives you an instant visual status check. If the light is on, your system is fighting the ice.
WHY YOU NEED THIS CONTROLLER
-
Set It & Forget It: Stop stressing about plugging and unplugging your cable manually. This controller automates the entire process.
-
Massive Energy Savings: By running only when temperatures drop below freezing, you eliminate hundreds of hours of wasted electricity usage per season.
-
Code Compliant Safety: Electrical code requires GFEP protection for all heat trace systems. This panel has it built-in, making your installation compliant and safe immediately.

🔥 PRO-TIPS FROM ERIC WIMMER
“The light is your best friend.” “I tell people all the time: the biggest failure point in a heat cable system isn’t the cable—it’s the homeowner forgetting to turn it on. With this panel, you don’t have to remember. But that LED? That’s your peace of mind. When you look out the window in a blizzard, seeing that little light glowing tells you your roof is protected without you ever stepping foot outside.”
⚠️ INSTALLATION WARNING
Must be installed by a Qualified Electrician. While this panel simplifies the control side, it involves line-voltage wiring. 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.
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.
