Customer Questions & Answers
Relay Panels has 26 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.

So glad I went with WarmlyYours
William M., Three Lakes, WI on 01/09/2024
I was slow to decide on a company to help me with my metal roof deicing project. I had a budget I needed to stay under. I wanted to do the work myself including the Electrical (my Dad is an electrician retired but would help). I decided on WarmlyYours because they had the best help video's, and staff to help plan and install my project. I didn't think I would get it up and running this year because of my late start. A slow start to winter let me get one leg of a two leg plan done up and running. Now we finally have snow and my one leg works great. This spring laying out the other leg will be easy (and warmer) this spring.

The WarmlyYours ice melt I recently installed is working great. They clearly have a 5 star product. I have only two slight complaints: none of the contractors referred by WY ever bothered to call back, so I had to find electrician and concrete guy myself. The plastic cover on the Snow Switch should be hinged instead of fastened with screws.
Excellent support, product, documentation, and stock
Mitchell S., Richmond Hill, ON on 11/15/2023
I had many questions, both while planning, and just before installation. WarmlyYours was great and answers, their on-line documentation is detailed and helpful, and everything was in-stock for pick-up. Looking forward to the snow.

From customer service to product quality, it was nice to have a company in your corner to help tackle a project.
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.
Wonderful as usually
Jasmine U., Oak Grove, MO on 06/04/2023
Pedro and the tech team were wonderful as usual
Great Customer Service for an Excellent Product
Richard K., Lakewood, NJ on 03/17/2023
Our experience with WarmlyYours was great from the beginning. They were easy to work with and provided a custom plan and all the necessary hardware to accomplish the job. We changed the design in the process and we were helped every step of the way. The system was on just this week and everything functioned accordingly.
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!
Mary knows her stuff. If she doesn't know , she calls you bac

Mary knows her stuff. If she doesn't know , she calls you back within minutes with an answer.
Good quality product
John E., Lakewood, CO on 06/21/2022
WarmlyYours is a good quality product. The mat was installed this spring. I haven't connected it to power yet. Technical support through the process was excellent . The product shipped and arrived on time. The price seemed a little high but sales staff worked with me to eliminate items I didn't really need to reduce the overall costs to a more palatable level. Recommend it!
