Support Page

Snow Melting Sensors Description

This kit includes a pavement sensor for detecting snow and ice along with a specialized housing unit for the sensor. 

The SIT–6E Pavement-Mounted Snow and Ice Sensor reliably detects snow and ice conditions on pavement surfaces when used with SC-MZ-TOUCH, SCA-DUAL, or SCP-120 controls. The SIT–6E pavement sensor ensures that deicing heaters operate only while needed which minimizes energy costs without sacrificing snow melting effectiveness.

As part of a snow melting system, a SIT–6E sensor will signal for snow and ice melting at pavement temperatures below 38°F (3.3°C) while moisture in any form—including water, snow, sleet or ice—is present.

It’s important for the sensor to be level with the pavement surrounding it. This is why a pavement sensor housing unit, ETI part number 23832 (included in this kit), is needed for each pavement sensor. This housing supports the sensor within the pavement and includes adjustment screws that allow proper leveling with the pavement surface.

For best results, consider using the SIT–6E pavement sensor together with an AIR-SS-2 aerial snow sensor. Including an AIR-SS-2 sensor will allow the snow/ice melting system to energize as soon as falling precipitation (e.g., snow or freezing rain) is detectable.

Customer Questions & Answers

Snow Melting Sensors has 26 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.

Jenn has provided one of the best customer support experience

Seward H., Gardnerville, NV on 06/03/2024

Jenn has provided one of the best customer support experiences we have ever had, every time we deal with her.

Very professional

Llc G., White Plains, NY on 04/19/2024

I needed this product asap.. They were on time and readily available for any questions!

Good product for the price

Mark G., Aston, PA on 01/02/2024

Other than some miscommunication on individual heat cable rolls versus pre-fabricated mats with cables already attached, the installation went pretty well. the control box I ordered was also backordered so needed to go with a more expensive model.

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.

Outstanding customer service, Pedro and the rest of the team

Vito P., College Point, NY on 11/01/2023

Outstanding customer service, Pedro and the rest of the team is always willing to help with any questions you may have. The heating mats are top notch and easy to install.

Great experience

Bill, Hawthorne, NY on 10/30/2023

From customer service to product quality, it was nice to have a company in your corner to help tackle a project.

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!
