Yes.
Heat Tape Pro & Piper Freeze Pro can both overlap and/or touch itself in your installation.
Heat Tape Pro
It’s fine to overlap your heat tape pro, or have it touching itself in your install. The cable only itself heats up to less than 100ºF at most. This is plenty of warmth to stop ice dams from forming, but isn’t that much warmer than the temperature of your body. Sometimes it won’t even feel that warm to the touch.
This is different than a lot of heat tape that can be purchased at stores: contestant wattage cable can get much hotter and can even be dangerous if you overlap them. Not our cable, however.
Pipe Freeze Pro
Pipe Freeze Pro can touch itself, overlap with itself, or be wrapped around itself on the pipe. It won’t get too hot because not only is it designed to have a maximum output temperature that is less than 100ºF, it is self-regulating –so it’s output adjusts to the ambient temperature near the cable.
