preventing pipes from freezing

[RUGMAN]

Has anyone had experience with the heat cables used to prevent pipes from freezing. I have a new crawl space under my cottage, the water service pipe runs up from the floor and runs across the ceiling and up into house. I looked on line and saw home depot sells a cable ( frost Line) that one runs along pipe has a thermostat attached that will keep pipes from freezing. It will be our first winter in our newly renovated cottage and want to be prepared.
