gutter/roof heat strip same as pipe heat tape?

[The Cobbler]

Is gutter/roof heat cable useable as indoor pipe heat tape?
I don't have the original package & nothing on the cable says for outdoor use only.
Thanks

I know late reply, but I was searching garagejournal for gutter cables reviews.

im finding the gutter cables only heat between 15*-35* which is completely different than the electric heat tape I have on my water pipes. The heat tape heats from 35* and lower. Hope that helps.
