WarmUp Snow Melting Questions & Answers

Warmup Snow Melting WSM

Q. How long does a snow melting system take to melt snow?

During typical Winter conditions, Warmup systems are designed to keep driveways and walkways clear of snow and ice with no waiting time.

To operate efficiently Warmup systems are designed to turn on before or at the first sign of precipitation below freezing. By anticipating a storm or sensing it quickly, Warmup systems are able to get slabs above freezing quickly to maintain constantly clear surfaces. With a warm slab, snow and ice quickly melt away without any waiting time.

Q. How far can you space snow melting cables?

If you are installing snow melting cable you may be wondering how far you can space the cable. Read more here about cable spacing.

Warmup recommends spacing snow melting cable at 3″ to deliver 50 watts per square foot. At 3″ spacing Warmup snow melting cable can deliver optimum results even under the harshest conditions.

Indoors or out, spacing heating cable further will decrease the heat output resulting in slower ramp-up times. Please refer to the chart below for a spacing guide.

Q. Should I use snow melting mats or snow melting cables?

Warmup offers two forms of surface heating: snow melting mats and snow melting cables.

Q. Can I Still Install my Snow melt System with Expansion Joints in the Concrete?

Installing Snow melt System with Expansion Joints

Yes, however careful planning is necessary to avoid any issues when the expansion joints are cut.

To avoid any issues, plan out where the joints are cut.

Ensure one length of the cable is tied to the floating rebar. The cable should be tied to either side of where the joint will be. At the end, the cable loops, connecting both runs of cable. Use a landscape hook to secure the loop far enough down to avoid the joint cuts.
