## 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
