Frozen pipes can cause many issues in your home, cottage, RV, or business. They can range from a loss of water supply or drainage to more severe problems from a burst pipe, which can cause damage to your property from flooding and lead to expensive emergency repairs. Fortunately, there are ways to help prevent frozen pipes and, with the right solution, eliminate any concern over them.

Taking steps such as applying pipe insulation or using space heaters in drafty basements will help. Still, they are often insufficient to prevent problems in extreme cold conditions. This approach is even more complicated when protecting exterior or shallow buried pipes, which are often inaccessible without excavation.
Another method to prevent plumbing from freezing is to apply heat externally or internally to your pipes. Let’s compare the most common solutions: self-regulating heat cables and heat tape.

Heat-Line self-regulating heating cable can be installed in a single run in many applications, offering a more energy-efficient solution compared to conventional heat tape, which needs to be spiraled around the pipe.

Two distinct heating methods are used to prevent freezing and maintain desired temperatures in various residential and industrial applications. Heat tape for plumbing is frequently found in hardware stores and available online from low-cost retailers. Although it is sometimes referred to as self-regulating heat tape, the term self-regulating heat tape is mistakenly used. Heat tape is, in fact, most often constant wattage and does not offer self-regulating technology. The preferable method is to employ true self-regulating heat cables. Self-regulating technology is used in all Heat-Line heating cable products. Although heat tape attempts to serve similar purposes to self-regulating heating, it differs significantly in its technology, safety features, reliability, and energy efficiency.

How Does It Work?

• Hardware Store Heat Tape:

Traditional hardware store heating tape operates using a simple concept. It consists of a resistive heating element encased in a protective outer sheath. When plugged into a power source, the entire length of the heating tape generates a constant level of heat regardless of the surrounding temperature. One of the significant concerns when using this type of heat tape for plumbing is that you must carefully monitor it for overheating, melting and fire risk.

• Heat-Line Self-Regulating Heating Cable:

Heat-Line self-regulating heating cable employs advanced technology to adjust its heat output automatically based on the ambient temperature. The self-regulating cables contain two parallel buss wires that are embedded within a conductive polymer core that responds to changes in temperature. As the temperature drops, the amount of electrical paths increase, allowing more current to flow between the buss wires and produces heat. Conversely, when the temperature rises, the amount of electrical paths decrease, decreasing the flow of current between the two buss wires and reducing heat output. This advanced operating characteristic makes self-regulating heating cable for pipes more energy-efficient and considerably safer than the constant wattage heat tape.

Self-regulating heating cables adjust their heat output based on ambient temperature, while heat tape maintains a constant wattage regardless of temperature.

Are Self-Regulating Heating Cables or Heating Tapes Safe?

• Hardware Store Heat Tape:

Constant-wattage heating tape lacks self-regulation, which makes it prone to overheating if improperly installed, misused, not accurately controlled, or closely monitored. When applied to empty or dry pipes, the unregulated heat can cause the pipe material to overheat, potentially leading to property damage or fire hazards. Similar products sold for roof heating use the same constant-wattage technology as heat tape for pipes, causing the same safety concerns.

• Heat-Line Self-Regulating Heating Cable:

Heat-Line self-regulating heat cables are completely safe. The cable’s ability to adjust its heat output prevents overheating, reducing the risk of fire hazards and enhancing overall safety during prolonged usage. Unlike heat tape for pipes, you can safely overlap Heat-Line self-regulating heating cable for pipes. The self-regulating cables can be used with metal or plastic pipes, even if they are dry. You can safely insulate over self-regulating heat cables to further improve efficiency.

Heat-Line self-regulating heating cables are safe to overlap, safe on dry pipes, safe on metal and non-metal pipes and safe to insulate.

Which is More Reliable?

• Hardware Store Heat Tape:

Constant-wattage heating tape often has a shorter lifespan and can be prone to failure in extreme weather conditions. Due to its potential safety hazards and inefficiencies, using heat tape for pipes is not recommended for critical or continuous heating needs.

• Self-Regulating Heating Cable:

Heat-Line self-regulating heat cables are reliable and long-lasting. Highly versatile and well-suited for pipe and roof applications, self-regulating cables are effective even in extreme weather conditions. They are manufactured of robust industrial-grade materials and can handle varying heat demands along their length, making them suitable for long pipe runs and installations with diverse temperature requirements. Their enhanced safety and energy efficiency make them the preferred choice for more demanding environments.

Heat-Line self-regulating heating cables are the most reliable heating cables on the market. They outlasts and outperforms any other heating cable systems and are safe for direct earth burial.

What is the Energy-Efficiency Like?

• Hardware Store Heat Tape:

Due to its constant heat output, hardware store heat tape is not energy-efficient, especially during milder weather conditions when full heating capacity is unnecessary. Due to the risk of overheating, heat tape for pipes often cannot be insulated, compromising its energy efficiency benefits.

• Self-Regulating Heating Cable:

A self-regulating heating cable stands out in terms of energy efficiency. As the temperature drops, the cable self-adjusts its heat output, reducing power consumption when less heat is required. This dynamic feature helps conserve energy and reduce heating costs over time. When using Heat-Line heating cable for pipes, it is also safe to insulate. Insulating enables the heating cable to perform even in extreme cold weather conditions and increases energy efficiency by up to 80%.

Heat-Line heating cables are safe to insulate, unlike conventional constant wattage heat tape, which can overheat when insulated.

Self-Regulating Heating Cables are the Preferred Choice

When comparing hardware store heat tape for plumbing or roofs and Heat-Line self-regulating cables for pipe and roof applications, it becomes evident that the self-regulating cables excel in technology, safety, reliability, and energy efficiency. Self-regulating heating cable is sometimes mistakenly referred to as self-regulating heat tape, but as you can see, self-regulating heating cable surpasses constant wattage heat tape in numerous features. Heat-Line self-regulating heating cable stands out as the wise choice for safeguarding pipes and roofs against freezing temperatures, thanks to its self-regulating technology, long lifespan, enhanced safety features, and superior reliability.
