Frequently Asked Questions
Showing all 5 questions
Power requirements are measured in Amps and based on three factors: the watts per sq. ft. of the snow melting cable or mat, the area powered and the voltage used for the application. Our PowerMat product is rated at approximately 50 watts per sq. ft. (with 3" cable spacing), so that is a constant factor. Most snowmelt projects are powered with 240V AC – not all, but most. The one factor that is always variable is the area to be heated/powered. That is based on your project. For a point of reference, let's use the example of a 350 sq. ft. concrete patio.
The formula is (50 W/sq. ft. x area of 350 sq. ft.) / V (240V) = Amps, so 17,500 / 240V = 72.9 Amps
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.
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.
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.
Our systems can handle low temperatures, but many controls come equipped with a Low-Temperature Lockout Feature. This feature prevents the system from running in very low temperatures. At very low temperatures it can become difficult for the system to effectively melt the snow. It is however possible to turn off this feature should you need the system to keep running during such low temperatures.
