No. The Light should be a solid color. If the light is flickering it could mean the cable is not working correctly and you should not install the cable on your pipes.

No, never install the Heating Cable kits in walls, floors, and ceilings.

Yes. The Heat Cable Kits can be used on plastic water pipes only if they are primary supply pipes with an outside diameter between 3/8" and 1½". The pipes should have, "Schedule 40," printed on the side.

Yes. For hot pipes, it is recommended that the heating cables should not be installed on pipes heated above 155 F. You should use the Heat Cable Kit on both your hot and cold water pipes if the pipes are exposed to the cold outside air. So, if your pipes are under the house, in an exposed crawl space, or against an exterior uninsulated wall; then it might be a good idea to use the Heat Cables on both hot and cold pipes. Remember, the water in the hot water line turns cold unless it is being used constantly.

No! The Electric Heat Cable Kits are made for copper, iron or Schedule 40 plastic water pipes only. Don't do it! No, never install the Heat Cable Kits on any type of hoses.

No, you should use each product as per the instructions. The Roof Cable Kit is made for roofs only. For pipe application, you will need a Heat Cable Kit.

No. Never ever overwrap the heat cable! Over-wrapping may cause the heating cable to overheat. Never use a cable longer than the pipe it is intended to protect. So don't do it.

Rubber Tubular Pipe Insulation can be used over the Heat Cable. But Fiberglass Pipe Wrap with Plastic overwrap or Faced Fiberglass Pipe Wrap is a better choice. The Wrap does a better job completely encapsulating the heat cable to hold in the heat and better protect the pipe. So... Yes, it is recommended that the heating cable is applied on the pipe, covered with  ½  inch fiberglass insulation or any equivalent non-combustible insulation with vapor seal.

When Installing the Roof Cable Kits on your roof edge using the "WWWW" pattern, a good rule of thumb is, for every 20 feet (including the downspout) of roof you plan to cover, you will need approximately 80 feet of Roof Cable. Ultimately though, it depends on the given overhang and other parts of the roof that needs to be protected. Take a look at the instruction manual for more information.  

If you plan on running the cable down the downspouts, you could use either the 160 ft or 200ft Roof Cable Kits.

All the Frost King Roof De-Icing Cable Kits (30 feet through 200 feet) carry a rating of 120V, 5 Watts per foot.
