Snow Melting Accessories Description

This USA-made embeddable attachment grid is for installing snow melting cables under pavers or on top of existing concrete surfaces such as stairs, walkways, or driveways. The primary use of this snow melting grid is to provide a framework to attach the snow melting cables to—typically with cable ties (sold separately). This allows for you to maintain proper spacing between the heating elements which will prevent overheating or "cold spots". Another benefit is that it allows you to control the depth of the heating elements to ensure optimal performance. 

In addition to being embedded under pavers or on top of existing concrete surfaces, this product can be embedded under bluestone or under tiles with thinset. Please note that this product should not be used with snow melting mats or in projects involving asphalt or a new concrete pour. 

This product comes as a 3' x 50' with a 1" x 1" square grid that allows for quick cable installation. The grid can also be cut in the field to accommodate different shapes. 

This snow melt grid is composed of high-molecular weight, high-tenacity multi-filament polyester yarns that are woven into a stable network placed under tension and coated with PVC. Product has an additional benefit like bi-directional expansion strength that is commonly used by landscaping and paving contractors.

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.

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.

Why a GFEP (GEFP, RCCB, or heat trace circuit breaker) and not a GFCI breaker for WarmlyYours outdoor deicing and snow melting systems?

This National Electric Code (NEC) required protection for fixed outdoor deicing and snow-melting equipment may be accomplished by using circuit breakers equipped with ground-fault equipment protection (GFEP) of 30 mA. It is important to understand that this required equipment protection is not the same as a 5 mA GFCI used for personal protection.

How much does a snow melting system cost?

The heating elements for a snow melting system typically will start at $9 ($11 CAD) per sq. ft. for Snow Melting Cables and $11 ($14 CAD) per sq. ft. for Snow Melting Mats. However, you'll also want to keep in mind the cost of a control, and if required, sensor/s for your snow melting system, which will add to the cost. Use our free Quote Builder to get an idea of how much a system would cost for your project.

What happens if the snow melt cable is damaged during the installation?

If a cable is damaged during installation, recheck the system for continuity and confirm the integrity of the insulation with a megohmmeter, or "megger" tester, referring to the installation and testing instructions. If the cable fails any of these tests, take the following actions: clear a 3 foot square working area around the damaged section of cable, and record the cable part number from the UL tag and the location where you purchased the product. Call WarmlyYours with the above information. WarmlyYours will provide further assistance and supply a splice kit suitable for repairing the particular cable.
