Will the snow melting system heat the riser or lip of the stair?

When heating stairs, we recommend minimizing or eliminating overhangs/lips on stair surfaces. It is very difficult for the heat to reach these protrusions, as heat only transfers, at most, 2" to 3” laterally from the cable. This is why we recommend placing a run of the heating cable right at the front edge of the stair, which will help keep this area clear of snow or frost as much as possible. The riser of the stair is not heated--only one run of cable goes down the riser to reach from an upper stair to a lower stair.
