Pipe heating cables, also known as heat trace or heat tape, are electric cables designed to be attached to pipes, ensuring that water continues to flow through poorly insulated pipes even in the harshest winter conditions.

Yes, this is normal. All YeloDeer heating cables with built-in thermostats use a mechanical thermostat, which has a typical tolerance of ±3°C. This means one cable may turn on around 5°C, while another may turn on closer to 1°C, and both fall within the normal activation range (ON at approx. 3°C/37°F, OFF at approx. 10°C/50°F).

To test the thermostat, place the sensor section in an ice-water mixture (0°C/32°F) — if the cable begins heating, it is functioning normally. These small temperature differences do not affect freeze-protection performance.

Deciding between in-pipe and on-pipe installations might seem straightforward based on application, but each method has unique benefits. For more details, please check out our blog-- In-Pipe vs. On-Pipe Installation for Pipe Freeze-Protection

Not at all, as long as the installation is done correctly. That said, improper installation, usage, or maintenance of heating cables can result in fires, electric shocks, or frozen pipes. Especially when using constant wattage cables, it's crucial to avoid bending or overlapping the cables.

By securing a heating cable to the outside of a pipe, it effectively transfers heat to the pipe, preventing it from freezing. Adding pipe insulation ensures that the heat is distributed evenly and retained longer, reducing the risk of heat loss.

If you are using self-regulating heating cables (e.g., our Blue Cable and Yellow Cable):

ꔷ You can wrap the remaining cable around the insulated water pipe. Overlapping is not a concern since our heating cable is self-regulating, allowing for greater heat output and improved freeze protection.

ꔷ Alternatively, if you have electrical skills, you can DIY by cutting off the excess cable and re-sealing the cut end with a waterproof heating cable end cap or using 2-3 layers of heat shrink tubing for waterproofing.

If you are using constant wattage cables (e.g., our Red Cable):

ꔷ Leave the excess cable outside, ensuring it does not come into contact with flammable materials or cause burns. You can cover it with insulation for safety.

ꔷ Do not attempt to wrap the excess cable, as this can lead to overheating.

ꔷ If necessary, consider replacing it with a more appropriately sized cable. Under no circumstances should you cut or re-seal constant wattage cables, as this is not suitable for this type of heating cable.

This approach ensures optimal performance and safety for your heating system.
