Snow Melt Cables Description
Protect your commercial parking garage ramp, sidewalk or patio — and your investment — with WarmlyYours’ 277V snow-melting cable. This 277V 100-foot-long cable installs in asphalt, in concrete, and under pavers to safely and effectively remove snow and ice. It is ideal for commercial projects and can accommodate spaces at a lower amperage than 120V, 208V or 240V systems.
The free-form cable measures ¼” (6mm) in diameter and generates 12 watts per lineal foot (50 watts per square foot at 3” spacing). It includes 50 feet of cold lead to minimize the number of junction boxes needed for each system.
All WarmlyYours snow-melting cables are CSA certified for outdoor use in the U.S. and Canada.

Customer Questions & Answers
Snow Melt Cables has 40 Questions and Answers.
How quickly do these systems melt the snow?
That depends on a number of variables (like the temperature outside) but generally speaking these snow melting systems are designed to melt 1" - 3" of snow per hour. Anything above 3" per hour is typically considered blizzard conditions.
Is it okay to cut the snow melting cable if it is too long for the application for which it was designed?
Never cut the heating cable. A heating cable will not work if it has been cut. If the heating cable is too long, call WarmlyYours to consult with a technician who will guide you in utilizing the additional length of cable.
How does the electric snow melting system compare to hot water tubing (hydronic) systems?
The material costs are similar. However, electric systems are easier to install, with fewer components and significantly lower maintenance costs. Electric systems will run for a shorter period of time to give the same level of performance but with much higher energy efficiency (typically 95%-98% efficient). Controls and sensors required for the two types of systems are very similar. Electric systems do not usually require slab insulation and do not create the concerns typically associated with hydronic systems. These concerns include, but are not limited to, return temperatures, flue gas venting, waterway shrinkage and property damage caused by leaking pipes or tubes.
May I cross or overlap the WarmlyYours snow melt heating cable?
When installing outdoor WarmlyYours snow melting cables for your driveway, patio, walkway, terrace, stairs, ramp, etc. - NEVER cross, overlap, or allow the heating cables to touch each other. Doing so will quickly cause a circuit failure due to excessive heat build up. Always follow the installation instructions and/or design layout plan to ensure the cable is installed with the correct spacing required for proper operation.
Does the factory splice need to be completely embedded during installation?
Yes. The manufacturer's splice that connects the heating element to the cold lead should be entirely embedded in a noncombustible material (like asphalt, concrete, or mortar) within the outdoor surface that is being heated.

Best service ever!
Marc C., Salt Lake City, UT on 10/19/2023
Mary was fantastic at listening and helping me find the best solution to melt ice and snow on my exterior stairs. Mary was kind and patient as this had many challenges and Mary worked through them all like a champ. We love our new system and love not shoveling.
Heating. Wire for driveway.
Vincent S., Wasaga Beach, ON on 06/07/2023
Easy to install, mostly because I have pavers on the driveway Your wiring looks very durable. My only concern is the exsesiers are very expensive. I had to look elsewhere for snow detectors for the unit. Otherwise I think your products are great.
Fantastic, knowledgeable, customer service
Jay R., Damascus, MD on 06/03/2023
Always a great experience with WarmlyYours. Efficient effective technology helps us with melting walkways and driveways as well as warming my feet in the bathroom etc.
Must have this if you live in a snowy region
Anonymous, Colorado Springs, CO on 01/03/2023
Works great! No more salt or shoveling!
No ice in front of the garage doors for the first time in years!
Anonymous, Leawood, KS on 05/06/2022
Our snow melting system was installed this fall and for the first time in years we did not have ice in front of the garage doors for weeks in the winter. The WarmlyYours staff were great to work with and answered our many questions with patience and knowledge.
Scott R., Omaha, NE on 02/01/2022
There is definitely a learning curve but after that it was great to see the finished product working. Customer was extremely happy.
Your online and telephone support system is the greatest!
Bonnie P., Sterling, AK on 10/17/2021
We just finished laying in the wire and poured our cement, just a day before it started snowing-so we are curing the cement as I type. The men are now hooking up the electrical inside portions. The instructions have been so easy to follow step by step. I wanted to let you know it was so easy, I decided to do the one side of my garage with both systems to have a longer driveway of warmth/snow melt...because it was so cost effective that our family man-power did the labor. I plan on contacting you next Spring after the thaw to order up more wire, etc to do the smaller 14 foot section, which will be turned into a bedroom with a big front window I hope to enjoy looking out during the winter, instead of looking at by past 6 foot snow falling off my roof and building a wall I can't see through. I will send the end result after the electrical is finished plus a photo. :):)
Will have to wait and see!
Cwhr R., Morrison, CO on 06/18/2021
Only the wire is installed in the new walk. I will not be able to give a full review till next winter.
Just as advertised!
Cory W., Sidney, MT on 02/15/2021
We have only had the chance to use it during the last storm~not complaining about that at all. The heated sidewalk worked just as it had been represented. Melted the snow enough to make it easy to remove & when it froze later, turning the heat on for a few hours took care of it. Very happy with this purchase.
Problem finding a breaker for this system!
Paul B., Lake Zurich, IL on 02/15/2021
Having difficulty finding the appropriate beaker to run this system. Tech support at WarmlyYours says one thing and the supply house where you need to purchase the breaker says another (not available at local Home Depot or Menards). It would be nice if there were a part number, a suggested list of preferred vendors and an up front price range before making this purchase. The prices quoted for this breaker were between $200-$700 (for one breaker)...the entire sidewalk heating system was $1,000. Still cannot locate to correct breaker! Frustrating...
Response from WarmlyYours:
Paul, We are sorry to hear that you are not able to locate the correct breaker for your installation. The GFEP breaker type for outdoor heating is dictated by the National Electric Code and should be selected based on your breaker panel type/brand. For your installation, one 15 Amp 240V GFEP Circuit is required as indicated in the installation and electrical plan. Feel free to reach out to us with the brand of your breaker panel and we will do our best to assist you and find the right parts or direct you to the right place.
