Which pipe heating cable is best?

Freezing temperatures are deadly to more than just living things. They are also more than capable of causing irreparable damage to your water pipes by freezing them until they expand and eventually burst. If you live in cold weather areas, using a pipe heating cable can mean the difference between a survivable winter and a bank-shattering pipe replacement bill.

The best pipe heating cable is the HEATIT Pipe Heating Cable. This best-of-the-best option comes in more than a dozen sizes from 3 feet long to 120 feet long. With an automatic on and off based on the included thermostat, you’ll never have to worry about your pipes again.

What to know before you buy a pipe heating cable


Installing a pipe heating cable is usually a difficult task, mostly due to the location of the pipes themselves rather than the mechanics of installation. Before you install your pipe heating cable, make sure you have the materials you need to attach the cable, as well as double-checking the instructions to know if you have to install your cable in a straight line or wrap it all the way around the pipe. Be sure to plug your cable in to make sure it heats up. With all of this done, you can begin installing.


A pipe heating cable is meant to help save your water pipes from the dangers of freezing weather, but they’re useless if they can’t resist that same exact weather. You also don’t want to have to repeatedly install a new cable. Read the user reviews on your prospective pipe heating cable to see how long they’ve lasted for other consumers.


Another key metric of reliability is the presence of two different certifications that each ensure that a pipe heating cable meets qualitative and operating standards. These certifications are UL approval for the United States only and CSA certified for the U.S. and other countries.

What to look for in a quality pipe heating cable

Ease of use

Pipe heating cables can have none, one or both of the following ease of use features.

Built-in thermostat: Selecting a pipe heating cable with a built-in thermostat is the easiest way to ensure you never forget to turn on your pipe heating cable. With a built-in thermostat, the pipe heating cable will automatically turn off and on when it detects the temperature of the pipe to be within a specified range, usually 50 and 38 degrees Fahrenheit.

Indicator light: Even if the pipe heating cable does include a built-in thermostat, you still can’t truly be sure it’s working without physically touching the pipe heating cable. Available options, including an LED indicator light, eliminate this problem by switching on the LED when the cable is plugged in and functioning correctly.

How much you can expect to spend on a pipe heating cable

Generally speaking, most brands of pipe heating cable will cost similarly enough to be a negligible variable, so all you need to worry about is how long of a pipe heating cable you need. Short pipe heating cables under 10 feet tend to cost less than $20, while you can get longer pipe heating cables up to 30 feet for $40 or less. The longest pipe heating cables, the 100+ foot options, can cost up to $120.
