Which the heat tape or cable won’t get damaged by crossing or touching itself when installed once...

Asked by Tad March 9, 2021

Answers

What happens when the cable is crossed against itself, is rubbing, which could lead to a short by rubbing through the insulation. The cable should run parallel to the water line pipe only. If the cable is a bit too long, it can be run back on the other side of the pipe. Make sure it does not touch.

The heat cables have a 1 year warranty and have a normal lifespan of 3-5 years.

Do the tapes come in different links?

Answers

Do you mean "lengths"? You cannot 'link' one cable to another. If you answered "Yes", then yes, they do come in different lengths.

After you install the cable can you put foam rap over it or will it melt the foam insulation

Asked by Tony February 12, 2021

Answers

Yes, you can use Foam Pipe insulation over the Heat Cable. It does not get hot enough to melt, only approx.90 degrees. However, we recommend using Fiberglass Pipe Wrap to overwrap the cable. It does a much better job distributing the heat along the pipe protecting it form freezing.

The light indicates power only. It illuminates the instant the cord is plugged in regardless of temperature.

Yes it is ok to use under foam. However, fiberglass would be a better option.

No, it will not work for this. The cable will not come on. It contains an automatic thermostat that senses temperature and does not have a manual setting.

The Frost King heat cable turns on at 38 degrees and turns off at 45 degrees

Works in gutters too!
Contrary to what the Home Depot employees will tell you, this item can be used in a gutter. The manufacturer confirms this on the Home Depot Q&A section. It works well to eliminate ice dams in gutters. I only plug the cable in when needed and has lasted all winter.

Great heat!!
Used this to prevent bulk rock salt from freezing in salt spreader. ( Not designed use) bulk salt if moist will freeze in single digits rendering salt useless when needed most. In stead of having to break apart and shovel out of hopper I can leave it in for frequent snow storms. Kept salt from freezing last night when it got down to -5f. Same salt froze in my loader bucket. Bottom line if it can do this it will work for your pipes.
