Review: A great solution to prevent pipes from freezing! - I bought this about a year ago due to a recurring freezing pipe in our basement when the outdoor temperature is in the single digits (or less). I finally got to try it out with this past week's (Jan 2026) negative degree temperatures in western PA. It worked GREAT! Our pipes did not freeze and the cable did not get hot - just warm.
Review: The Best! - Amazing product. They simply work. I did not have to play weeks of games battling freezing pipes during this cold snap, which is ongoing. The days of dripping water, leaving cupboard doors ajar, and heating the freeze points with a hair dryer or small torch are over. Nothing worked before. Neither insulated tape nor pipe foam nor fiberglass packing. These do. I am so very happy.

## Questions & Answers

**Q: what are the monthly expense to run**
A: To update Mike's answer for 2022. 7 watts per foot @ 30ft = 210watts. Divide by 1,000 = .21kW x 24 hrs = 5.04 kWh per day x cost of electricity in your area (this ranges from $0.2254 to $0.0937 depending on your state) so it could range anywhere from ~$0.47 to ~$1.14.

**Q: Can this be used on pex plastic pipe?**
A: You can use it on plastic pipe if the pipe will always be filled with water, but don't wrap it - just run a straight line. See the Frost King website: http://www.frostking.com/wp-content/uploads/Pipe_heat_cable_trifold.pdf

**Q: is it thermostat controlled and if not, at what temperature will it be activated? there is existing pipe insulation can the cable go on top of it?**
A: Frost King HC6A 6 Feet Automatic Electric Heat Cable Kits, Black

**Q: Is it safe to have the cable wrap the pipe inside a foam pipe insulator cover, or will it melt the foam insulator?**
A: I ABSOLUTELY had it melt foam insulator before.  Do NOT overlap it.  I have pics of where it burned through foam pipe insulator because I sued contractor for almost catching my home on fire

### ⭐⭐⭐⭐⭐ Easy to install. Works great!
*by S***B on February 20, 2026*

Easy to install. Works great. I installed these on the supply lines to my sinks in a new bathroom I had built out in an unfinished attic space at my vacation lake house in NC. The plumbers ran those lines on a day I was not there as I would have preferred that they run them under the floor because the attic gets very cold in the winter and the house sits empty most of the winter. I was concerned the supply lines would freeze and rupture, flooding the house. So far, I’ve made it through the coldest part of the winter without any issues. I also installed older Wi-Fi enabled thermostats to monitor the attic spaces. They did get well below freezing on a few days so am glad I installed these!
