REHOSEUP Hpt-5w-110v-A 18 ft Self-Regulating Pipe Heat Tape, 5W/ft, 120V

For protecting exposed water lines from winter freezes, this 18 ft REHOSEUP heat tape brings active heat to plumbing in outdoor and other cold-weather settings. Its self-regulating design adjusts heat output to surrounding temperatures, helping keep warmth responsive to changing conditions.

At 5W per foot and 120V, it is designed for pipe freeze protection along the cable’s length. The flexible tape supports straight, spiral, and overlap installation, making it easier to follow different pipe layouts.

A UV-resistant TPE jacket helps the cable withstand sunlight, moisture, and outdoor exposure. Use it on compatible PVC, PEX, or metal pipes in plumbing setups such as cabins, farms, barns, and RVs.

Fit and sizing

The 18 ft length suits exposed pipe runs where a heat cable can be routed along the plumbing. Plan the route around the section that needs freeze protection, then choose a straight or spiral wrap to follow the pipe layout. Overlap installation is also supported, offering another way to position the tape where the run calls for it.

The cable is designed for PVC, PEX, and metal pipes. This makes it relevant across a range of plumbing materials, from water lines at a cabin or barn to exposed plumbing on an RV. For a project that relies only on passive pipe insulation, this product takes a different approach: it adds regulated heat along the line. Its 120V power specification is important when planning the installation.

Benefits

Self-regulation adjusts heat output in response to ambient conditions, while built-in temperature control helps regulate warmth during extended operation. That combination is intended to provide consistent pipe warming and help reduce overheating. Rather than applying a fixed heat output regardless of surrounding temperature, the cable responds to the conditions around it.

For exposed outdoor plumbing, the UV-resistant TPE outer jacket is designed to handle sunlight, moisture, and weather exposure. This construction supports seasonal winter use on water lines and other outdoor plumbing applications. The flexible format also helps the cable conform to different pipe routes, so installation can follow the layout instead of requiring one wrapping pattern.

In practical use, the tape can be routed along an exposed water line at a cabin or farm before cold weather arrives. Its 5W/ft output provides heat along the cable, while the self-regulating design adjusts to ambient temperatures. For RVs and barns, the same pipe-focused design addresses exposed plumbing where maintaining water flow through cold weather matters.
