Waterproof Outdoor Thermostat Support

Heat tape is electrical equipment: improper installation, damaged cable, or misuse can cause fire or electric shock. Select cable approved for your pipe and location, follow its layout and insulation requirements, provide the specified electrical protection, and inspect it before each cold season. Do not use damaged equipment or overlap cable unless the exact product instructions permit it.

Yes, it can be used for both application types to prevent pipes from freezing and bursting during cold weather.

No. They are not designed to be powered by DC voltage. They must be used with AC voltage. 

Heat trace, heat tape, or heating cable for pipes is typically an electric heating cable that can be attached to the pipe which helps keep non-flowing water pipes in poorly insulated perimeter walls flowing despite harsh winter temperatures.

Pipe heat tape is intended for freeze prevention, not as a guaranteed way to thaw an already frozen pipe. A frozen pipe may be damaged. Have the plumbing assessed and thawed safely by a qualified professional; never use an open flame. Before future cold weather, verify cable selection, thermostat placement, insulation, and electrical protection.

By attaching a heating cable to the exterior of a pipe, it will transfer the heat to the pipe to prevent frozen pipes. And with the use of pipe insulation the heat will be evenly spread and won't dissipate as quickly.

WarmlyYours does not recommend using an extension cord for permanent installations. Pipe heat should always be plugged directly into a receptacle or hardwired to the circuit that is powering it.

No.  It is not listed for this application, and it is not warrantied for use in direct burial or wet applications.

No. Only install pipe heat (heat trace cable) in accessible locations. Do not install this self regulating cable in walls or any place where the cable is hidden. Do not run it through walls, ceilings, or floors. The cable must be installed 10“ away from combustible surfaces, such as wood, and it should not be embedded in insulation or roofing material.

Do not wrap self regulating cable around the pipe in a coiled or spiral fashion, and do not use electric tape to attach it. WarmlyYours recommends attaching the cable in a straight run and to use aluminum or fiberglass tape, pipe straps, or plastic zip ties to attach the cable. Then cover the assembly with fire-resistant insulation and assure it is waterproof. Place electrical heating cable WARNING labels every 10‘, and where the label will be clearly visible.
