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.
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.
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.Ā
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.
In addition to showing the status of the snow/ice melting system and controlling the hold-on time, the RCO will turn on/off the heat for these controllers.
Note:Ā When the Heater Cycle switch is momentarily depressed, it will start a manual Heater Cycle for the Cycle Time setting.Ā Momentarily depressed while heaters are being operated by a Hold-On Timer or during manual Heater Cycle will end the Heater Cycle. Heater operation during snow conditions cannot be canceled in this manner.
The snow melting system is not operated by a thermostat, it is operated by either an automatic or manual controller.Ā AĀ snow melting controller does not maintain temperatures like an indoor thermostat does.Ā An automatic snow melting controllerĀ only turns the snow melting system on when it detects precipitation and the temperature outdoors is below the set temp (typically 37.4Ā°F / 3Ā°C).
