Customer Questions & Answers

Can it be used to keep a truck engine block warm?

I'm thinking about wrapping it around my truck's radiator hoses and radiator at the bottom with tie-wraps. How hot in degrees Fahrenheit does it get?
Asked by: gearhed
you might be better off with a dip stick heater to keep the block warm. Your anti freeze should keep the coolant from freezing. You could use a digital temperature controller and a heat lamp or incandescent bulb under the engine. Digital temp controllers are 15 bucks or so on line.

can heat tape be used over a white drinking water hose on a camper

Asked by: anne
Yes, but you have to secure it. Used outdoor cable ties,then covered both hose and heat tape with pipe insulation, then secured both together with more cable ties. Worked to -4° with no problems.

The product video shows insulating the pipe once the wire is taped on. Is this necessary, or just for efficiency?

Asked by: Bns
You do not need to insulate the pipe the heat cable is on.

Can this be used outside and placed in a gutter to prevent freezing?

Asked by: tlinmaine
No, Do not use outside. A roof cable kit is what is needed to run through a gutter.

I have used this product, and others like it, before to help regulate metal pipe temperatures and was assisting someone else this time. While the product works well in any application, you need to read all the instructions to be sure that you don't do something wrong: like try to install it inside a wall where it becomes a fire hazard. This, like any other electrically-driven item, is a power tool and needs to be used with caution. So long as you are smart in how you use it and follow the directions, it CAN make the difference for your exposed pipes.

Rated 5 out of 5 by from Frost King Heating Coil for Water Pipes Wow. I wish I had installed this years ago. Every year our water pipes, on the north side of the cottage, would freeze up when the temperatures dropped into the teens. I would have to run the electric heater for several hours to get the water to flow again or blow heat from the kerosene heater into the crawl space, which I did last year. The foam insulation I put on the pipes did little to prevent the pipes from freezing. After I install a 12 foot heating coil on the cold water pipe and a six foot line on the hot water pipe, it worked like a charm. Hardest part was wrapping the foil back fiberglass installatiion around the pipes after installing the heating coil. Be sure to wear a good air mask and goggles. Temperatures were in the low single digits last night and even below zero the other day and still the water didn't freeze. Didn't even have to drip the faucets. I am so grateful I put it in this year. I would highly recommend this for anyone having frozen pipes. Also I called Frost King to ask them a question about the installation and it was great to have a real person on the other side of the line. I'm a happy customer. Thanks Frost King and thanks Home Depot.

Rated 5 out of 5 by from Works as advertised I have used this product for years under my house where the waterline comes out of the ground and up into the house. Since it is controlled by thermostat I leave it plugged in year round. Never had ANY problems and my pipe does not freeze anymore.

Rated 5 out of 5 by from Works Flawlessly Worked perfectly to un-freeze an outside frost free water hydrant in my horse barn, and kept water flowing in sub zero temps. Installed easily, and works perfectly.

Rated 1 out of 5 by from Failed right out of the box Glad I tested it. Left alone in a room that was 15° for 45 minutes and the cable was not heated at all. Tested the voltage draw and it was just one watt (for the light at the end of the cord).

Rated 1 out of 5 by from Manufacturer Contact Very difficult When trying to call the manufacturer to ask clarifying questions about product questions, like “what temp does the cable operate at” for product uses (details specify copper but also plastic pipe other places so I wanted clarification) was impossible to do because repeatedly, and I mean “very” repeatedly, I tried calling. The each time after waiting my position it the call queue, my turn would come and I’d get disconnected because it would go to voice mail and the queue was full. All that can do is hurt business. I started looking for different products.
