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.

No, as long as it's properly installed. However, improper installation, use, and/or maintenance of electrical heating cable can cause fires, electric shock, and/ or frozen pipes.

Unfortunately there's no set answer for this because it depends on many factors such as the diameter of the pipes, the installation density of the heating cables, the outdoor temperature, the installation of thermal insulation sleeves, etc.

As the names imply, constant wattage cable uses fixed wattage output per linear foot and does not automatically adjust in response to temperature changes. Self-regulating cable is manufactured with a resistance matrix placed between its 2 buss wires that varies the ohms resistance per linear foot to automatically adjust in response to temperature changes. Learn more about this in our blog Self-Regulating vs. Constant Wattage Heating Cables.

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.

Never spiral heating cable around pipes. Attach self regulating cable in straight runs at the 8 o'clock position, or if two runs are required (pipes greater than 12“ diameter) attach the cable at the 8 o'clock and the 4 o'clock positions. Please refer to the installation manual for further information.

Use plastic zip ties, aluminum or fiberglass tape, or pipe straps. Do NOT use vinyl electrical tape, masking tape or duct tape. Do NOT use metal wire or metal twist ties to attach the cable.

WarmlyYours offers a conversion kit (SR-PLUG-KIT) to enable a plug-in requirement. This kit includes ground fault equipment protection (GFEP). The receptacle must be 120V, grounded, and approved for wet locations if located outside. The self regulating cable must not exceed 140‘ in length.

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.

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.
