## 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

### ⭐⭐⭐⭐⭐ Works in extreme low temperatures

### ⭐⭐⭐⭐⭐ 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!
