Customer Questions & Answers

Snow Melting System Junction Boxes has 30 Questions and Answers.

Don't see the answer you're looking for? Post your question

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.

Excellent customer service

Paul S., Manhattan, MT on 07/09/2024

Every item in multiple orders was received promptly.

Good choice

Mike M., Lakewood, CO on 12/11/2023

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.

Wonderful as usually

Jasmine U., Oak Grove, MO on 06/04/2023

Pedro and the tech team were wonderful as usual

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.

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.

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!

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.

Learning Curve

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. :):)
