Review on Pre-Assembled 6Ft Self-Regulating Pipe Heating Cable - 120V By HEATIT For Efficient Winter Protection by Ryan Eastman

I installed this on a water line in an area that was prone to freezing if you did not leave the faucet running in cold weather. At the time I installed this I also installed a temperature sensor on the pipe tied into my home automation system. I was then able to trend the pipe temperature and saw that the built in thermostat worked well cutting the heater on when the pipe reached 37 degrees, and off around 50 degrees. It was quite consistent. For a note, it actually called for a GFI receptacle, so get one and do it all at once.
