Pipe heating tape, also known as heat tape, is an electrical device used to prevent pipes from freezing in cold temperatures. It consists of a flexible heating element that is wrapped around the pipe and connected to an electrical source. The tape is designed to maintain a constant temperature that is warm enough to prevent the water inside the pipe from freezing. Pipe heating tape is commonly used in areas where the temperature drops below freezing, such as in northern climates or in unheated areas of a building. It is particularly useful for pipes that are located in areas that are difficult to insulate, such as outdoor pipes or pipes located in crawl spaces. There are two main types of pipe heating tape: self-regulating and constant wattage. Self-regulating tape adjusts its heat output based on the temperature of the pipe, while constant wattage tape maintains a constant level of heat output regardless of the pipe temperature. Self-regulating tape is generally more energy-efficient and easier to install, while constant wattage tape is better suited for longer pipes or pipes with a consistent diameter. In addition to preventing pipes from freezing, pipe heating tape can also be used to thaw frozen pipes. However, it is important to use caution when using heat tape for this purpose, as excessive heat can damage the pipe or cause a fire.
