Easyheat NPRO-100 Self-regulating Heat Cable 100 Ft 120V

Product Description

The EASYHEAT NPRO-100 is a self-regulating heat protection cable designed to prevent pipe freeze damage in residential plumbing systems. Running 100 feet in length and operating at 120 volts, this cable outputs 3 watts per foot and automatically adjusts its heat output based on ambient temperature conditions — increasing output as temperatures drop and reducing output as conditions warm. Licensed plumbers and HVAC technicians install this cable along exposed or vulnerable pipe runs to maintain safe temperatures during cold weather. The self-regulating design eliminates the risk of overheating and reduces energy consumption compared to fixed-wattage heat tape.

This cable is suited for residential applications where water supply lines, drain pipes, or other plumbing runs are exposed to freezing temperatures — including crawl spaces, attics, exterior walls, and unheated utility spaces. It is commonly installed on copper, PVC, and other standard pipe materials. The 100-foot length accommodates longer pipe runs or routing around obstacles without splicing. Installation is completed without special high-voltage wiring — the cable plugs into a standard 120-volt outlet.

Key Features

• Self-regulating technology automatically adjusts heat output to match ambient temperature
• 100-foot cable length suits extended or complex pipe runs
• Operates on standard 120-volt residential power
• 3 watts per foot output provides reliable freeze protection
• Reduces energy use compared to constant-wattage heat tape by cutting back output in warmer conditions

Compatibility

Designed as an OEM-style residential self-regulating heat cable for use on standard pipe materials in freeze-prone locations. Consult the manufacturer installation guide for specific pipe diameter and insulation pairing recommendations.

Installation Notes

Installation is typically performed by a licensed plumber or experienced HVAC technician in accordance with applicable local plumbing and electrical codes. Before installation, ensure the pipe surface is clean and dry, and confirm the circuit breaker serving the outlet is rated appropriately for the cable load. The cable should be spiraled or run straight along the pipe per manufacturer instructions and covered with pipe insulation to maximize efficiency. Do not overlap the cable on itself, as concentrated heat buildup can damage the cable jacket.
