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 freeze protection for cabins, well water lines, seasonal homes, farm water systems, outdoor plumbing, 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.

Quick Fit Snapshot

In-Pipe Freeze Protection Installed inside the water pipe to help protect freeze-prone sections from within.

For Pressurized Water Lines Designed mainly for potable water pipes and pressurized water supply lines.

3/4 in and Larger Pipes Actual cable path must maintain at least 17mm / 0.67 in inner opening.

Cable Only or Kit Choose Cable Only for manual use or Kit for automatic temperature control.

Choose the Right Option

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

Cable & Controller Kit Choose the Kit if you want automatic temperature control, easier winter operation, and improved energy efficiency for seasonal or long-term use.

Self-regulating does not mean the cable turns fully off by itself.

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

For easier winter operation, better energy control, and automatic temperature-based switching, use this cable with a compatible temperature controller, sold separately.

FAQ & Resources

Frequently Asked Questions

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.

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, fitting type, and actual inner opening before ordering.

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.

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.

Can I cut the cable shorter?

For standard plug-in products, choose the correct length before purchase.

If you need a special length, select the Custom option or contact us before ordering.

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.

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.

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.

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.

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.

Both are designed for pressurized supply lines, but they differ in how the heating cable enters the pipe, how they adapt to pipe sizes, and how they affect water flow:

Entry Method

Y Fitting: Uses a Y-pipe with hose barbs sized for 3/4 in, 1 in, and 1-1/4 in pipes. Beyond 1-1/4 in, it becomes unsuitable because the 1 in throat creates a bottleneck.
T Fitting: Requires an additional T-pipe fitting and an adapter. With the adapter, it can accommodate a wider range of pipe sizes, making it more flexible.

Effect on Flow

Y Fitting: Maintains a straight flow path; no change in the water direction.
T Fitting: Alters the flow direction into an L-shape, since the cable enters through the side branch of the T.

Best For

Y Fitting: Quick installs on small to mid-sized pipes (≤1-1/4 in) where keeping a straight flow is important.
T Fitting: Larger or mixed pipe systems where you need more flexibility in pipe sizes and installation points, even if the flow path changes.

No, this in-pipe heating cable is not suitable for sharp bends like 90-degree or 45-degree elbows. If your pipe has such abrupt turns, you'll need to replace those sections with smoother, sweeping bends to allow the cable to pass through easily.

Yes, it can be used, but we also offer heating cables specifically designed for sewage and wastewater pipes. The main difference between this in-pipe cable and the dedicated version is that the latter is not as pressure-resistant. However, it works perfectly for open-ended sewage pipes or drainage channels, and it’s also more cost-effective.

For more details, please check the link--In Drain Pipe Heating Cable.

No, you generally do not need to reset the GFCI (Ground Fault Circuit Interrupter) after a regular power outage. The GFCI only requires a manual reset if it detects a ground fault (leakage).

In the event of a standard power outage, the GFCI should not trip, and once the power is restored, the system should resume operation normally unless a ground fault is detected at that time.

No, the heating cable can be inserted without directional limitations. It works effectively in either direction, making it ideal for both water supply and drainage systems, no matter the direction of water flow.

Applicable for:

Supply Pipes: Pumping water from lakes or rivers.
Drainage Pipes: Removing water from inside your home.

Yes, this product is designed for use with pipes in 3/4-inch and above. However, please ensure there are no sections of your pipe, such as at fittings or connectors, where the inner diameter is reduced to less than 17mm (0.67 inches). If such restrictions exist, the heating cable may not fit properly.

Ask a Question

I have approximately 40 feet of 1 1/2 inch pipe running between two buildings. The water line connection is pretty straight. The pipe runs underground and recently froze due to extreme cold. The plumbers thawed it out but now we are looking for a solution to keep it from happening again. Will this line dramatically (or materially) reduce the volume of water going to the second building? Second, the cold spot is in the middle of the "run" between the two buildings. Can the sensor be placed in the middle and the run continue on to the end of the run? Third, is there a "smart" feature that I can log on to and see what the water temp is? Finally, is it one end only, meaning I don't need to do anything at the other end?

Dear Mr. Drapeau,
Thank you for your questions regarding our Food-Grade In-Pipe Heating Cable. We are happy to provide the following clarifications:
Regarding water flow volume: A 1 1/2 inch pipe will not dramatically or materially reduce the volume of water going to the second building. We have not received any customer feedback indicating flow restrictions with this pipe size when using our heating cable.
Regarding sensor placement: The sensor probe is designed to be placed at the coldest spot of the pipe run. It can absolutely be placed in the middle of the run between the two buildings, and the heating cable can continue to the end of the pipe as needed.
Regarding "smart" features: Our intelligent thermostat controls the heating cable based on the pipe or air temperature detected by the sensor, activating it when temperatures drop to a set threshold. While it effectively prevents freezing, it does not currently support direct logging or remote viewing of water temperature.
Regarding installation: Our heating cable is designed for single-end connection. This means all electrical connections and controls are at one end, and no additional work is required at the opposite end of the pipe run.
We hope this information helps you make an informed decision. Please let us know if you have any further questions or need additional details.
Best regards,
Hello can I leave my heating cable always plugged in Thank- you

Hello Floyd,
Thank you for reaching out.
You can keep the heating cable plugged in if you have anti-freezing requirements.
However, when the weather is warm and there is no need for pipe-freezing protection,
please unplug the cable to ensure safety and energy efficiency.
Thanks and regards,
Demi
What diameter is the heating cable?

The heating cable diameter is 10.7*5.0mm (0.42*0.2in).
How flexible is the inline heating cable. Can I feed it through a 1" 90 degree fitting

Thanks for your question！
No, this in-pipe heating cable is not designed to bend around sharp 90-degree or 45-degree elbow fittings. If your pipe has abrupt elbows, they need to be replaced with sections that create sweeping bends to allow the cable to pass smoothly. Important Notice: Forcing the cable through sharp elbows can damage the end seal, potentially causing water leakage. Many leakage issues result from improper installation, so please ensure careful installation.
At what temp does the line kick in and heat up

Thank you for your question! Since this product does not have a built-in thermostat, it begins heating as soon as it’s plugged in, regardless of the external temperature. However, due to its self-regulating feature, it adjusts the output power based on the surrounding temperature—when the temperature is higher, the output is lower, though it’s still in a heating state.
If you’d like more precise temperature control, we also offer a bundle that includes a Pipe Heat Tape Thermostat, allowing you to manually set the temperature at which it turns on and off.
Is the 6’ power cord in addition to the 15’ measurement of the actual heat cable, or included with the entire measurement(6’ power cord, 9’ heat cable)?

The length indicated on our product pages refers only to the length of the heating cable and does not include the power cord.
However, please note that for the in-pipe heating cable you inquired about, the power cord is actually 4 feet long.
