Self-Regulating Heat Trace

Cables automatically adjust heat output with ambient temperature, helping prevent overheating and supporting cut-to-length installation.

Pipe Freeze Protection

Protects residential and light commercial metal & plastic water lines with reliable heat-trace cable options.

Roof, Gutter & Downspout De-Icing

Helps reduce ice dams and keep meltwater flowing through gutters and downspouts in freezing conditions.

Ground-Fault Protection

Designed for installations that require GFCI / ground-fault protection on heating cable branch circuits.

De-Icerman Self-Regulating Heating Cables for Pipe Freeze Protection and Roof & Gutter De-Icing

De-Icerman sells self-regulating heat-trace cables that respond to temperature changes along the cable length. Use them to help prevent frozen pipes, reduce ice dams, and keep gutters and downspouts draining during winter weather. Explore interactive sizing tools below to estimate cable length, compare maximum circuit lengths by breaker size, and choose the right heat output for your application.

Quick Specs

Supply Voltage

110–120V or 208–240V

Max Exposure Temp

85°C (185°F)

Min Install Temp

-20°C (-4°F)

Bend Radius

1 in (25 mm) @ -20°C

Tip: Use sensors/controllers to maximize efficiency since self-regulating cables reduce output but do not shut off completely.

Interactive Sizing Graphs & Calculators

Pipe Heat-Trace: Maximum Cable Length per Circuit Breaker

Select voltage, model, start-up temperature, and breaker size to see the maximum allowable cable length.
Breaker Lengths (ft)
These values help you keep each circuit within allowable maximum length.

Roof & Gutter De-Icing: Maximum Cable Length per Circuit Breaker

Compare maximum circuit lengths for DSR-RGS-12 based on voltage and start-up temperature.
Breaker Lengths (ft)
Normal power output reference: in ice/snow at 0°C ≈ 12 W/ft, in air at 0°C ≈ 10 W/ft.

Roof & Gutter Cable Length Calculator (DSR-RGS Layout)

Estimate total heating cable length for roof edge zigzag, gutters, downspouts, dormers, valleys, and connections.
Calculator uses the standard layout formula: Roof Edge × multiplier + Roof Extension + Dormers + Valleys + Gutters (+ wide gutter) + Downspouts + Connection allowances.
Estimated Total Cable Length
Use this to select a kit length and plan circuits.
Multiplier: —
