The most common spacing for snow melting systems is 3“ from wire to wire. However, we can design snow melting systems based on your local climate and weather expectations that might have different cable spacings to ensure the most efficient system possible. We also offer snow melting mats with 3" and 4" spacing.

In an area free of obstruction and able to detect rain or snow, yet low enough so that it is easily accessible if service is needed. Atop a fence post or on an 'L' bracket on the side of a building are common.

A 2 pole single-phase 240V circuit works by continuously monitoring the current flowing through both hot wires of the circuit. If it detects even a slight imbalance between the current on each hot wire (indicating a ground fault), it will quickly trip, cutting off power to the circuit. Essentially, it compares each leg of the 240V circuit and trips if they are not precisely equal.

This feature prevents the snow melting system from running, by default, in temperatures below 17°F (–8.33°C), or as set by the user. At temperatures this low, it becomes difficult for the system to effectively melt the snow. It is, however, possible to turn off this feature should the system be required to keep running during these low temperatures.

Yes. After the snow melting cable is installed, ensure that a minimum of 1.5" (Max 3") of non-combustible medium (concrete, mortar, stone) is placed on top.

Was this helpful? Yes No

Yes, your contractor would need to remove the existing tiles (if present) from the staircase and flatten the surface prior to installing the grid.

Was this helpful? Yes No

Start at the top and work your way down.

Was this helpful? Yes No

The grid could be attached with concrete screws and washers.

Was this helpful? Yes No

Cut a slit in the area of the lift or distortion to flatten it out.

Was this helpful? Yes No

It is recommended to install a screw every 1 sq ft to ensure the grid does not shift or distort when the heating cable is installed.

Was this helpful? Yes No

It is easiest to start on one end of the grid and pull the grid tight as you go working the way across.

Was this helpful? Yes No

Yes, it is important to ensure the grid is stretched taut in the same direction as the snow melting cable.

Was this helpful? Yes No

The best home features for cold climates include a simple gable roof to shed snow, covered entrances for protection, airtight triple-pane windows to prevent heat loss, and radiant heating systems. These features work together to maintain interior warmth, reduce energy bills by up to 25%, and ensure structural safety during harsh winters.
