Ask Frost King: How Long Will the Heat Cables Last?

How long does the Heat cable kit last?
They have a one-year warranty built-in, but customers get three to five years - No problem.

I plan on using on a covered screen porch. Will they last longer if not exposed to sunlight and rain? Also I live in Florida, if I don’t plug them until December and unplug them in April, will they last longer?
