Thermwell Products HC18 Pipe Heat Cable 18 ft.

Amazing product. They simply work. I did not have to play weeks of games battling freezing pipes during this cold snap, which is ongoing. The days of dripping water, leaving cupboard doors ajar, and heating the freeze points with a hair dryer or small torch are over. Nothing worked before. Neither insulated tape nor pipe foam nor fiberglass packing. These do. I am so very happy.

I bought this about a year ago due to a recurring freezing pipe in our basement when the outdoor temperature is in the single digits (or less). I finally got to try it out with this past week's (Jan 2026) negative degree temperatures in western PA. It worked GREAT! Our pipes did not freeze and the cable did not get hot - just warm.

Easy to install. Works great. I installed these on the supply lines to my sinks in a new bathroom I had built out in an unfinished attic space at my vacation lake house in NC. The plumbers ran those lines on a day I was not there as I would have preferred that they run them under the floor because the attic gets very cold in the winter and the house sits empty most of the winter. I was concerned the supply lines would freeze and rupture, flooding the house. So far, I’ve made it through the coldest part of the winter without any issues. I also installed older Wi-Fi enabled thermostats to monitor the attic spaces. They did get well below freezing on a few days so am glad I installed these!

I’ve used these before very reliable and works great but had to return this one I ordered the wrong size my bad

worked great. thawed out a frozen pipe in minutes

Very good heat kit. I used to use the Frostex heat kit, used them for many years, but there expensive and their controller cannot get wet. This Frost King is waterproof which is a big plus. This Frost King does Not have an adjustable wire length, you could cut the Frostex to fit but not these Frost Kings, so get an accurate measurement of what length you need. I had installed a 12-foot Frost King but it turned out to be too long, I had to remove it and install this 9 footer.

I live in Frazier Park and my plumber said I need to replace my heat strip on my water line. It was easy to install and is a good quality product, I recommend buying it and it is reasonably priced. I have used other Frost King products and I have never been disappointed...

Works great. Our well kept freezing up, no longer a problem. I also combined this with the frost king insulation. I would suggest reading the installation booklet. I see some review pics where the heat tape was obviously installed wrong. (You are not supposed to coil it around the pipe) Plus the black sensor is to be placed against the pipe.
