Food-Grade In-Pipe Heating Cable (CSA, 230 PSI, >3/4") | YeloDeer

Overview

Food-Grade In-Pipe Heating Cable for Water Pipe Freeze Protection

The YeloDeer In-Pipe Heating Cable is designed to help protect pressurized water supply lines from freezing in winter. Installed directly inside the pipe, this self-regulating heating cable provides reliable freeze protection for cabins, well water lines, seasonal homes, farm water systems, and other exposed or hard-to-insulate water lines.

Unlike external heat tape, an in-pipe heating cable delivers heat from inside the water line, making it a practical solution when the pipe is buried, exposed to extreme cold, or difficult to wrap from the outside.

Choose the Right Option

1. Cable Only: Choose Cable Only if you already have a compatible controller, prefer manual operation, or only need the in-pipe heating cable itself.

Please note: when used without a controller, the cable will continue to operate while plugged in. The self-regulating heating cable adjusts its heat output based on the surrounding temperature, but it does not fully turn itself off.

For easier winter operation, better energy control, and automatic temperature-based switching, we recommend using this cable with a compatible temperature controller. Customers who purchase the Cable Only option can also buy the controller separately at any time.

2. Cable & Controller Kit: Choose Cable & Controller Kit if you want more convenient automatic temperature control and improved energy efficiency. This kit is recommended for seasonal use, long-term winter operation, and customers who want the system to turn heating on and off based on temperature settings.

The kit includes the heating cable, a compatible temperature controller, and multiple adapter sizes to help fit common pipe connection needs.

Before You Order

Please confirm the following before purchase:
1. Your pipe size and fittings can provide a minimum inner opening of 17mm / 0.67 in.
2. The cable can enter through a proper pipe entry point, such as a T-fitting or compatible adapter.
3. The pipe does not contain sharp 90-degree or 45-degree elbows that may block cable insertion.
4. You have measured the full length of pipe that needs freeze protection.
5. For custom length, long runs, or 240V requirements, please select the Custom option or contact us before ordering.

For drain, sewer, sump, or wastewater applications, we recommend using a dedicated YeloDeer In-Drain Heating Cable instead.

Sharp 90-degree or 45-degree elbows
Pipes with blocked or unknown internal routing
Pipes without a suitable cable entry point
Pipes smaller than the required minimum inner diameter
Applications where the cable may be forced through tight fittings or sharp turns

For Drain or Sewer Pipes

Although some customers ask about using in-pipe heat cable for drainage applications, pressurized water lines and drain/sewer lines have different requirements.

For open-ended, low-pressure, non-potable drain or wastewater systems, please choose a dedicated YeloDeer In-Drain Heating Cable for a better fit and more cost-effective solution.

For best results:
Do not guess the pipe length.
Do not choose a much longer cable than needed.
Check the full cable path before ordering.
For long pipe runs, confirm whether fish tape or puller assistance is needed.
For custom layouts, send us your pipe length, pipe size, voltage requirement, and photos before purchase.

Installation & Accessories

Installation Overview

This in-pipe heating cable is installed through a suitable pipe entry point, such as a T-fitting, Y-fitting, or compatible adapter. The cable is inserted into the water line to protect the pipe from freezing from the inside.

Basic installation steps:

1. Identify the pipe section that needs freeze protection.
2. Shut off the water supply before installation.
3. Install a proper pipe entry fitting or adapter.
4. Confirm the minimum 17mm / 0.67 in inner opening.
5. Insert the heating cable into the pipe carefully.
6. Avoid forcing the cable through sharp bends or restricted fittings.
7. Connect the GFCI plug to a properly protected outlet.
8. If using the controller kit, place the sensor correctly and set the desired temperature range.

Important Installation Notes

* Do not force the cable through sharp elbows.
* Do not install through fittings with reduced inner diameter.
* Do not cut or shorten a standard plug-in cable unless the product instructions specifically allow it.
* Use proper insulation on exposed pipe sections to improve freeze protection and reduce energy use.
* For long pipe runs, fish tape or puller assistance may be required.
* For uncertain layouts, contact us before installation.

Accessories and Kit Options

Depending on your pipe system, you may need:
* T-fitting or Y-fitting

FAQ & Resources

Frequently Asked Questions

1. Can this heating cable be installed inside a drinking water pipe?
Yes. This product is designed for pressurized water supply lines and uses a food-grade jacket suitable for potable water pipe freeze protection.

2. Do I need a T-fitting or adapter?
In most installations, yes. The cable needs a proper pipe entry point, such as a T-fitting, Y-fitting, or compatible adapter. Please confirm your pipe size and fitting type before ordering.

3. What pipe size is required?
This product is designed for pipes 3/4 in and larger, but the most important requirement is the actual inner opening. The cable path must maintain at least 17mm / 0.67 in inner diameter.

4. Can this cable pass through elbows?
It is not suitable for sharp 90-degree or 45-degree elbows. Gradual bends may work, but the cable should never be forced through tight or restricted turns.

5. Can I cut the cable shorter?
For standard plug-in products, please choose the correct length before purchase. If you need a special length, select the Custom option or contact us before ordering.

6. Does this cable need a controller?
A controller is not strictly required, but it is highly recommended. Without a controller, the cable will keep operating while plugged in. A controller helps reduce energy use and provides automatic temperature-based operation.

7. Does self-regulating mean the cable turns off by itself?
No. Self-regulating means the cable adjusts its heat output based on the surrounding temperature. It reduces output in warmer areas and increases output in colder areas, but it does not fully shut off by itself. To fully stop heating, disconnect power or use a controller.

8. Can this be used for drain, sewer, or sump pipes?
For drain, sewer, sump, or wastewater applications, we recommend using a dedicated YeloDeer In-Drain Heating Cable. It is better suited for open-ended, low-pressure, non-potable drainage systems.

9. Is it safe if the pipe is dry or empty?
The self-regulating cable reaches a stable maximum temperature and is designed to reduce overheating risk. However, installation should always follow the product instructions and the cable should be used only in suitable applications.

10. What should I do if I am not sure which length or fitting I need?
Please contact us before ordering. Send your pipe size, pipe length, photos of the installation area, voltage requirement, and a brief description of your application. Our team can help you choose the right option.
