General Installation Tips for Low-voltage De-icing System

Warmzone's RoofHeat™ STEP® radiant roof heating systems feature a unique, thin, flexible heating panel that can be installed directly under shingles or metal roofs. The low-voltage polymer heating element can be nailed or stapled through, making installation much easier than that of other roof heating systems. The discreet roof heating system is easily installed under the roof material to heat the roof edges as well as valleys. Potentially damaging snow buildups and ice dams can be eliminated with the use of this effective, low-profile roof heating system. Because the heating element is self-regulating, less energy is used as the material gets warmer, making RoofHeat STEP a very efficient roof de-icing solution, and a favorite among installers and homeowners alike.

General Information About Warmzone's Low-voltage Roof Heating SystemLow-voltage roof heating element being installed to heat resort hotel roof

The low-voltage roof de-icing system is one of the most effective systems for keeping roof areas clear of snow and ice. The thin, self-regulating polymer heating element can be discreetly installed under shingles and metal (standing seam) roofs. The semi-conductive heating panels are available in different widths, so they can be installed along the roof eaves as well as in roof valleys and even gutters.

RoofHeat STEP low-voltage systems are relatively easy to install. The panels are laid out over the area to be heated and then the bus wires are connected. Transformers are used to step down high voltage to low voltage (60 V or less) while controlling a specific section of the roof de-icing system. These individual control boxes are the source for monitoring the power and output to the heating element to ensure safe, accurate, and efficient performance. The advanced TOUCH thermostat is recommended for controlling the roof heating system. Warmzone's low-voltage roof de-icing systems have been providing effective snow and ice melting for residential and commercial properties for nearly two decades.

General Features and Installation Tips

Low-voltage roof de-icing system heating elements being installed

Even though the heating elements are self-regulating, they should not touch, cross, or overlap. at any point.

The heating element can be easily cut to the desired length on site.

The heating element can be bent up to 90 degrees to fit roof valleys, or almost any contour or crease.

RoofHeat STEP is a low-voltage product and should only be energized via the supplied power packs.

Do not exceed the maximum run of material as indicated in the design details from Warmzone.

This product should only be installed in accordance with local and national codes, ordinances, trade practices and manufacturer instructions.

Heating elements should be installed in temperatures between 40°F and 140°F (4°C to 60°C).

In cold conditions, the polymer heating element can be stiff and brittle, and therefore must not be bent or folded. Rolled up heating elements may be energized for a short period of time to make them warm and softer, but they must be constantly observed to avoid overheating while in the roll.

Installation of Roof De-icing System Components

RoofHeat STEP radiant roof heating and de-icing systems contain three main components: The step-down transformer, polymer heating element, and the STEP Touch thermostat (activation device).

Specially Constructed Low-Voltage Heating Element: The thin RoofHeat STEP heating element is polypropylene fused during fabrication to achieve water proofing and ensure that the panel is protected against UV rays and other potential physical damages.

To expose the two longitudinal bus braids, cut the plastic on each side of the braid with scissors or make a score in the plastic, front and back, with a knife.

Bend the element where the cut is made and pull off the corners to remove the surplus of plastic. Make sure that the bus braid is not cut or damaged; should this occur, re-cut the element and re-strip the bus braids.

Connect the bus braid to an extension wire, #12AWG (4 mm2) PVC insulated, stranded tinned copper wire, 105 C, 600V. Crimp the joint using the recommended tinned copper connectors and crimp tool. IMPORTANT: Check that the connections are secure. NOTE: Using components not recommended by the manufacturer will void the warranty.

Warmzone radiant roof de-icing systems are fairly easy to install when compared to other radiant roof heating systems. A qualified electrician should be able to easily install the system. Roofing contractors should be able to install a majority of the system before having an electrician hook up the power. In addition to our free installation training and complete system design services, Warmzone also provides technical support five days a week. Radiant heat product literature such as installation manuals and system diagrams are also available online on our product literature page.
