Pipe Freeze Pro

Pipe Heat Tape Kit to Protect Your Pipes from Freezing down to -40ºF: Dry Locations Only

Pipe Freeze Pro is an 8mm self-regulating heat cable that generates 3-5watts per foot, making it a perfect choice for typical indoor residential pipe freeze prevention projects. The built-in thermostat triggers the cable to turn on at 37ºF and off at 50ºF, which prevents wasting unnecessary electricity by only energizing the cable when it’s needed. Pipe Freeze Pro can be overlapped without risk of shorting or fire.

No need for a ThermaCord: PipeFreezePRO has a built-in thermostat

More About Pipe Freeze Pro

Dry Locations Only

Our Plug-in Pipe Freeze heat tape Kit is designed for residential and commercial pipe freeze protection on pipes made from both metal (copper & steel) and plastic (ABS, PVC, PEX). Our cables are self-regulating, so they only ask for the power they need to heat the pipe above freezing. This saves you a lot of money in the long run by not wasting electricity like constant wattage Pipe Trace heat tape. Kits include heat tape, high-temp fiberglass tape to affix cable to pipe, awesome installation manual and electric warning labels.

Simply plug the cable into any GFCI 120V receptacle (can also be plugged into a standard outlet as long as the circuit is GFCI protect). Pipe Freeze Pro details:

    • Self-Regulating , Includes a built-in Thermostatic Switch to control power to heat tape – The cable Automatically turns on and off, then regulates its temperature and power consumption, optimizing for the surrounding temperature. This uses less energy and save you money. The built-in thermostatic switch has a 4ºF +/- temperature sensitivity.
    • Since temperatures modulate, Pipe Freeze Pro will not overheat, or pose a risk of fire like other heat tape. Pipe Freeze Pro can overlap and touch itself. Standard heat tape can not do this.
    • Produces 3 watts per foot (at 50ºF) and 5 watts per foot (at 32ºF) and below.
    • Suitable for metal or plastic pipes up to 6″ for pipe heat tracing applications.
    • 40″ Cold lead plug-in cord
    • UL listed for use in Dry Locations
    • 10-year manufacturer’s warranty

IMPORTANT NOTES: Pipe Freeze Pro is not designed to thaw already frozen pipes, for exposure to wet environments, for installation inside pipes and drains or for burial. You must cover heat cable with insulation for it to work. Do not use this cable for applications other than pipe freeze protection.

Pipe Freeze Pro FAQs

Yes. Pipe Freeze Pro can be used on any commonly available pipe material including PEX, PVC, ABS, galvanized steel, copper and cast iron. This cable operates at somewhere between 40ºF and 90ºF so it will not melt anything (except chocolate).

No. Not even close. Our cables operate at between 40ºF to 90ºF so they will not melt or damage any surface or material they come into contact with. Except chocolate. Our cables will thoroughly melt chocolate.


It is not recommended to use pipe. Freeze pro inside of pipes. Consider using Heat Tape Pro inside of open drain pipes as that cable is rated for use in wet areas.

Sort of.

Like Heat Tape Pro, Pipe Freeze Pro should not be installed on pipes that regularly heat up to over 150ºF as this may cause longterm damage to the heat cable. It therefore depends on how hot you have your water heater set to. On average, water heaters are set to about 140ºF to prevent scalding.


Heat tape cables should not be installed in any permanently hidden areas.

Totally. Pipe Freeze PRO can be overlapped during installation. This is a fundamental advantage of self-regulating heat cable over cheap, constant wattage cable found in hardware stores is that it can be overlapped without risk of shorting out or catching fire. So yes, overlap away!

Good news. Heat Tape Pro and Pipe Freeze Pro are the only heat cables in the world you can see is working. The GlowCap™ is the LED end cap used to terminate all of our pre-terminated heat cables. If you see the green light glowing at the end of the cable, the cable is working. We also offer a GlowCap™ End Seal Kit for field assembled cable systems. Another quite obvious way of determining if your heat cable is working is to feel if it is warm.

Because our heat cable can be overlapped, there is no specific way to wrap valves. A simple loop of cable around the body of the valve will be enough. A couple things to remember. First, try to keep the cable in contact with the valve so the heat transfers effectively from the cable to the valve. Next, do your best to insulate the valve to protect it from the cold. This often means getting a little creative with the same insulation you use for the pipe. You can use a scissors to cut the insulation into one or more shapes and then secure those shapes to the valve with tape (duct tape works well). Speaking of tape, remember to use our fiberglass installation tape to secure the cable to the pipe.

The amount of heat cable needed for pipe freeze prevention is determined by a couple of simple factors including: Length of pipe, diameter of pipe, distance to power supply and number of valves.

We do not recommend a spiral cable application mostly because it’s simply not necessary. It requires 3x the cable to do the same job.

Therefore, simply use a straight, single run of cable affixed to the bottom of the pipe (think 6 o’clock position) using the provided fiberglass installation tape. Next, add 1 foot of cable for every valve because you will be wrapping the valve with cable. For pipes less than 1″ in diameter, a single cable run is sufficient. For larger pipes, two cable runs are recommended. Keep in mind that plastic pipes are less thermally conductive so you may choose to use two cable runs on larger plastic pipes to be safe. Finally, if your outlet isn’t close to the pipe you are treating, factor in enough heat cable to reach your outlet (Pipe Freeze PRO does come with a 36″ power cord).

Finally, you must install insulation on your pipe and heat cable assembly in order for the system to operate effectively. See instructions for further details.

PipeFreezePRO comes with one or more 30ft tools of high-quality fiberglass tape, but you can use any tape with a minimum temperature rating of 176º F. Self-adhesive aluminum foil tape can be used but avoid standard tapes, including electrical tape and duct tape because they lose their adhesion when exposed to heat. Remember, it’s imperative to cover the pipe/heat tape assembly with pipe insulation (1/2″ minimum thickness). Think four easy steps: 1) cable on pipe, 2) tape on cable, 3) insulation on pipe/cable and 4) tape on insulation. 

The Thermostat keeps the heat cable turned off (and thus draw no power) until it detects temperatures below 37ºF. Once it turns on, the self-regulating aspect takes over and directs heat to the area(s) of the cable that are in contact with the cold. The thermostat should be positioned outside of the insulating layer so it can effectively read the temperature of the air.


While the cable itself can be exposed to moisture you should keep the thermostat in a dry location.


You must cover pipe, freeze prevention, cable with insulation under all circumstances. Otherwise it will likely fail to do its job. This includes both Pipe Freeze Pro and Heat Tape Pro.

Use a minimum 1/2″ thickness standard pipe insulation.

Pipe Freeze Pro’s integrated thermostat turns power on and off automatically to the cable to save electricity. The thermostat is the lump located between the power cord and the heat cable. The thermostat triggers the cable to turn on at 37ºF and off at 50ºF, with a sensitivity range of +/- 4ºF.  It’s a great feature that makes Pipe Freeze Pro unique among heat cables on the market.

Can Pipe Freeze Pro get wet?

Yes and no. The cable is approved for exposure to wet conditions but you should keep the thermostat dry for proper operation.

Does the thermostat/sensor need to be touching the Pipe?

No. The thermostat need only be exposed to cold air. It does not hurt to have the thermostat attached to the pipe but it is not necessary. If you choose to attach it to the pipe keep in mind that the thermostat should not be covered with insulation.

Should the thermostat be under the insulation?

No. You want the thermostat to react to the cold environment so it triggers the Pipe Freeze Pro to turn on.

Heat Tape Pro is our line of robust, outdoor rated cable. It’s designed specifically for the demands of extreme environments including wet locations such as outdoor pipes, open drain lines and of course roof and gutter de-icing applications.nnDo not use Pipe Freeze Pro as it is rated for dry locations only.

Heat Tape purchased in big-box stores is most often constant wattage heat tape. “Constant Wattage” means: it’s always on. It is always drawing full power and is costing you peak energy expenses, which –over the length of a season can add up huge. Thought you were saving money on that heat tape you got at that home improvement store? Guess again.

Radiant Solutions’ Heat Tape PRO™ heating cable is Self-Regulating. This means, as the temperature gets colder, the cable creates more heat by drawing more power and when it gets warmer it creates less heat by drawing less power. This allows you to consume only the energy you need to help protect your home from damage caused by the ice and cold.

How can it do this?

The core of our ice dam heat tape is comprised of two bus wires encased in a material that is infused with carbon. As ambient temperatures decrease, the core material shrinks pulling the bus wires closer to each other, creating more electrical pathways through the carbon which makes the cables heat up. When ambient temperatures get warmer, the inner core expands and the cable demands less energy and creates less heat.

Can’t I just accomplish this with constant wattage heat tape and a “switch” or thermostatic control?

No, not really. Because any control or switch is still going to tell your constant wattage cable to be either off or on at 100% power. It is very binary. Conversely, Self-regulating Heat Tape will output variable temperatures based on the external, ambient temperature. So when it’s 31ºF or 10ºF constant wattage heat tape will always be on full heat, where self-regulating heat tape will only use just enough power to be at the temperature you need to prevent ice dams on the roof or frozen pipes around your property.

There’s also some safety considerations.

Among other things, constant wattage heat cable cannot be overlapped without creating risk of over heating or shorting out. It cannot be used under 15°F, it cannot be used on wood roofs, rubber roofs, metal roofs, or anything other than asphalt shingle roofs. You must clean combustibles such as leaves away from constant wattage cable throughout the operating season. The warranty on most constant wattage heat cable systems is no more than two years. Lastly, unlike self-regulating heat cable systems, constant wattage heat cables cannot be repaired in the field if they are damaged. One knick in the jacketing, and the cable is done.

Pipe heat trace cable is the same thing as heat tape or heat cable. The terms are used interchangeably to refer to a category of cables designed to keep water in pipes from freezing.

Heat Tape Pro is rated for wet locations and outdoor environments. It is ideally suited for outdoor pipes and can be installed in open drains, such as 4″ PVC pipes for gutter system drainage. Do not use Pipe Freeze Pro for wet location pipe freeze protection.

The short answer is NO. Self-regulating heat cable does not turn itself on and off automatically. To do that you need to put the cable on a switched circuit or outlet or on a controller. Of course, you can also be old-school about it and simply plug and unplug as needed.

“Self-Regulating” refers to the fact that these cables are temperature sensitive. Due to their construction, these cables sense changes in temperature along their entire length, demanding more power as temps fall and less when they rise.

PipeFreeeze Pro™, Pipe Freeze Protection Solution has a built in thermostatic switch, meaning it will turn on and off on it’s own.

Heat Tape Pro™, does not contain a built-in thermostatic controller. We recommend adding the ThermaCord™ Thermostatic controller to turn your Heat Tape PRO to turn the cable on and off with changes in temperature.
