How long does it take for pipes to unfreeze if heat tape is installed?

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.

There are too many variables to provide an accurate answer. Even though this product is designed to keep pipes from freezing, it is not designed to thaw pipes. If your pipe has frozen with the heat tape installed and energized, please check the placement of the built-in thermostat and verify that the insulation has been properly installed and waterproofed.

What is the power output of this self-regulating pipe freeze protection cable?

We sell three different max power outputs: 10W/ft. 8W/ft., and 5W/ft. Because these cables are self-regulating, the actual power output will depend on the temperature (i.e. the lower the temperature, the higher the power output).Ā

How does this type of pipe freeze protection cable work?

Self-regulating heating cables, like PRO-Tect: Pipe Freeze Protection cables, use a conductive polymer core, which continually adjusts its heat output.
This is why Ā­Ā­Ā­Ā­Ā­this type of cable, unlike some heat tapes, wonā€™t burn out if it is wrapped closely together, overlapped, or over-insulated. This also means lower operating costs and increased energy efficiency.Ā

How much heat tape for pipes will I need for my project?

The amount of cable needed depends on the size and type of pipe, and on the lowest expected temperature. Once you know the type of pipe (metal or plastic), pipe diameter, length of pipe, and the minimum expected temperature, you can use this formĀ to request a quote. Just follow the instructions on the form to get it back to us.Ā

Is the self-regulating pipe freeze protection cable always on? Is there a built-in thermostat?

There is no built-in thermostat, but we do have recommended WarmlyYours controls which will activate the system for continuous operation at 40Ā°F or below.Ā

Do I have to use insulation when installing self-regulating heat trace cable?

Yes, insulation is highly recommended for use with a pipe freeze protection system for the following reasons:

Ā·Ā  Ā  Ā  It helps cut down on heat loss from the heated water pipe.Ā 
Ā·Ā  Ā  Ā  Properly installed insulation helps keep the cable in good contact with the water pipe so that maximum surface area contact is achieved.Ā 
Ā·Ā  Ā  Ā  While the cable is wet location approved, weatherproofed insulation adds an extra layer of protection. Ideally, the insulation will be nonflammable and waterproofed.Ā

How do I attach the heat trace cable to the pipe?

We recommend using a fiberglass-based tape, which is available from WarmlyYours.

Is there a maximum length for self-regulating pipe freeze protection cables?

Yes, there is a maximum cable length that can be supported. However, this maximum length depends on the cable type (in terms of wattage per linear foot), the cable's voltage, and the ambient starting temperature. You can find out more by referring to the Maximum Length vs. Circuit Breaker Size chart found in the manual.Ā

Can I plug self regulating cable into an electrical outlet?

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 140ā€˜ in length.

Can pipe heat be installed in walls?

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 10ā€œ away from combustible surfaces, such as wood, and it should not be embedded in insulation or roofing material.

Once we installed the Self-Regulating cable and plugged it in, we noticed it was heating. Doesn't this self-regulate and not turn on until is is cold?

Self-regulating cable heats to the specified watts per linear foot when energized

What is the difference between WarmlyYours Ice Shield and WarmlyYours Pro-Tect self regulating cable?

Ice Shield is 120V or 240V and outputs 5W/ft, and is designed for roof and gutter deicing.
PRO-Tect is 120V or 240V and outputs 5W/ft, 8W/ft, or 10W/ft, and is designed for pipe freeze protection.
