1.0 Product Specications
WarmlyYours Heating Cable is designed for outdoor driveways, walkways, stairs and
patios. It is well suited for large areas like driveways.
The Heating Cable is comprised of a dual, multistrand heating element with a primary
insulation of Fluoropolymer. The insulated core is then protected with a woven metal
braid and an outer jacket of PVC, EPR or Zero Halogen Polyolen based compound
to make it sturdier and to provide corrosion protection. These cables are terminated
with 20’ (6.1m) for 120V/240V or 50’ (15.2m) for 208V/277V long standard cold leads.
The hot and cold junction is uniquely designed to make it 100% fool proof.
The Snow Melting Mat is a cable in mat (1.25” x 1.25” mesh openings) construction
which consists of the Heating Cable taped on a Polypropylene (PP) mat. The Heating
Cable is laid in a serpentine fashion so that it is equally spaced and distributed on
the (PP) mat.
Available in a wide range of capacities and sizes to suit your requirements, the Snow
Melting Mats and Heating Cables are identied as indicated below.
Item Number: AAAA-BBB-CCCC
Ex: Item Number: WHMA-240-0250
(product type) (voltage) (width & length = 2’x50’)
• AAAA = WHMA for Snow Melting Mat, WHCA for Snow Melting Cable
• BBB = Operating Voltage available in 120V, 208V, 240V and 277V
• CCCC = Mat width in ft. (rst two digits) and Mat length in ft. (third and fourth
digits) for Snow Melting Mat, Cable length in ft. for Snow Melting Cable
The available sizes of Snow Melting Mats are shown in Appendix A. The available
lengths of Snow Melting Cables are shown in Appendix B. Both Appendices include
the following attributes for each Item Number.
