ThermaCord FAQs

What does a heat tape thermostat cord like ThermaCord do?

ThermaCord is a smart power cord with a built-in thermostat that automatically turns roof de-icing cables on and off based on temperature. It powers on at 37°F to prevent freezing and shuts off at 50°F to save energy. This keeps your heat tape from running 24/7 when it isn’t needed, lowering your electric bill while keeping your home protected.

Will ThermaCord work with any 120v plug-in heat tape system?

Yes. ThermaCord works with any plug-in roof de-icing cable or pipe heat cable that plugs into a standard 120V outlet and draws 1500 watts or less. It’s a perfect match for Heat Tape Pro, but also works with most heat tape brands you’ll find at hardware stores.

How much can I save on electricity with ThermaCord?

Savings vary by climate and electricity rates, but in most cold regions ThermaCord cuts energy use by up to 30-50%, depending on outdoor temperature fluctuations and the duration it’s used. For many homeowners, it pays for itself in the first winter season and then keeps saving money year after year.

Can I change the on/off temperature settings?

No. ThermaCord is pre-programmed to turn on at 37°F and off at 50°F. These settings are based on decades of ice dam prevention experience to balance maximum protection with maximum energy savings. The fixed settings mean there’s nothing for you to adjust or program.

Is ThermaCord safe for outdoor use?

Absolutely. ThermaCord is outdoor rated, weather resistant, and built to handle snow, rain, and subzero temperatures. The 16-inch cord length gives flexibility for outlet placement while keeping the connection protected.

Why not just unplug my heat tape when it’s warm out?

You could, but most people forget — and a surprise cold snap could leave your home unprotected. ThermaCord responds automatically, even in the middle of the night, so your roof and gutters are always protected when temperatures drop.

Can I use ThermaCord for things other than roof heat cable?

Yes. ThermaCord is often used to control livestock water tank heaters, greenhouse heaters, poultry warming lamps and pads and other equipment that benefits from automatic temperature control. As long as the device plugs into a standard 120V outlet and draws under 1500 watts, ThermaCord can control it.

How do I know if ThermaCord is working?

The ThermaCord comes with indicator lights in both the plug and receptacle. The plug will glow when it's being energized so you know your outlet is working. When the thermostatic switch allows power to the receptacle, the indicator light in the receptacle will glow as well. When the ThermaCord is supplying power to your heat tape it will warm up. If you’re using Heat Tape Pro with GlowCap™ LED end cap, you’ll see the green light illuminate when it’s active. The controller itself operates silently.

What kind of warranty comes with ThermaCord?

ThermaCord includes a 3-year warranty and is UL approved for safety. It’s engineered to last through years of harsh outdoor use. Since most customers save enough in electricity during the first winter to cover the cost, the warranty gives you extra peace of mind.

Do I need an electrician to install ThermaCord?

Not at all. Installation takes 30 seconds. Plug ThermaCord into your outlet, then plug your heat tape (or other device) into ThermaCord. That’s it.

How quickly can I get ThermaCord?

We keep them in stock and ship same day from Minnesota, don’t ‘cha know. (As long as you don’t order it too late in the day, of course). Orders placed over the weekend will ship the next business day.

Where can I find the specs on my ThermaCord?

Easy. Click here to view the spec sheet.

Can ThermaCord be used with pipe heat cables?

Yes. ThermaCord is commonly paired with pipe freeze heat cables that don’t already come with built-in thermostats. It automatically powers the cable only when temperatures drop, keeping pipes protected while cutting unnecessary run time.

Will ThermaCord work for sump pump discharge lines or condensate drains?

Yes. Sump pump and furnace drain lines often freeze in cold climates. Plugging heat tape into ThermaCord ensures those lines stay clear during cold snaps but don’t waste energy during warm spells

Can I use ThermaCord with RV or boat water lines?

Absolutely. ThermaCord works with heat tape applied to RV water hoses, boat shore hoses and other seasonal water lines as long as it draws less than 1500 watts. It’s a simple way to protect your system without having to remember to plug and unplug.

How is ThermaCord different from a timer?

A timer just turns heat tape on and off at set hours. ThermaCord responds to actual outdoor temperature. That means it turns on during unexpected cold snaps (even in the middle of the night) and stays off when it’s warm, which saves more energy and gives better protection.

Is ThermaCord basically an extension cord with a thermostat?

Yes, that’s a good way to think of it, but with professional-grade outdoor durability and UL approval. Unlike a basic extension cord, ThermaCord is purpose-built for roof de-icing cable, pipe heat tape and outdoor heating devices.

Does ThermaCord work with 240V systems?

No. ThermaCord is designed for 120V plug-in devices only. If you need to control a 240V hardwired system, check out our controllers designed for field-assembled Heat Tape Pro spools.

Can ThermaCord prevent my heat tape from running all the time?

Yes, that’s one of its biggest benefits. Without a controller, plug-in heat tape runs constantly whenever it’s plugged in. ThermaCord only powers the cable when temperatures are between 37°F and 50°F, saving 30–50% in electricity use.

Is ThermaCord compatible with GFCI outlets?

Yes. ThermaCord is designed to work safely with GFCI-protected outlets, which are required for outdoor use. If your outlet doesn’t have GFCI protection, we recommend upgrading before installation.

Can I run multiple heat tape runs on one ThermaCord?

We recommend getting one ThermaCord for each heat cable to keep things simple.

General FAQs

PipeFreezePRO comes with one or more 30ft rolls of high-quality fiberglass tape, but you can use any tape with a temperature rating of 150º F and above. 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. 

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!

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. 

Most of the time, we do not recommend a spiral cable application 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.

No. Pipe Freeze PRO is not designed for use in outdoor conditions.

The cable can be exposed to wetness but the thermostat must stay dry to function properly. Use Pipe Freeze PRO for pipe freeze prevention applications only.

No. 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.

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.
