Easyheat NPRO-50 Self-regulating Heat Cable 120V 50 Ft

Product Description

The EASYHEAT NPRO-50 is a self-regulating heat protection cable designed to prevent pipe freeze damage in residential applications. Rated at 120 volts and 3 watts per foot, this 50-foot cable automatically adjusts its heat output based on the surrounding temperature, consuming more energy in colder conditions and less as temperatures rise. At 3 pounds, it is lightweight enough for a single technician to handle during installation. Plumbers and HVAC technicians install this cable on water supply lines, including both metallic and plastic pipe, to maintain safe operating temperatures through winter. Self-regulating technology eliminates the risk of overheating associated with fixed-wattage heat tape.

The NPRO-50 is suited for residential pipe freeze protection on exposed or semi-exposed water lines, including pipes running through unheated crawl spaces, attics, garages, and exterior walls. At 50 feet in length, it covers longer pipe runs without splicing. Typical installs include cold-water supply lines and drain lines that pass through unconditioned spaces. Licensed plumbers and HVAC technicians are the primary installers, though knowledgeable DIYers familiar with low-voltage electrical work can handle this cable in residential settings.

Key Features

• Self-regulating output automatically increases wattage in colder ambient temps and reduces it as temps rise, preventing overheating
• 50-foot length covers extended pipe runs without mid-run splicing
• 120-volt input compatible with standard residential electrical circuits
• 3 watts per foot output provides consistent low-level freeze protection on water lines
• Lightweight at 3 pounds for single-technician handling and installation

Compatibility

Designed as an OEM-style self-regulating heat cable for residential pipe freeze protection applications on standard water supply and drain lines in unconditioned spaces.

Installation Notes

Installation should be performed by a licensed plumber or qualified electrician in accordance with NEC guidelines for heat tracing systems. Shut off water supply and de-energize any adjacent circuits before beginning work. Secure the cable along the pipe following manufacturer spacing recommendations and avoid overlapping the cable on itself, as this can cause localized overheating even on self-regulating models. Connect the cable end plug to a properly grounded 120-volt GFCI-protected outlet as required by code for heat tracing installations.
