Attention Frost King Weather-strip EXPERT. Stay with your weather-stripping, you obviously don't know anything. You are steering people AWAY from exactly what they need. Absolutely this heat tape can be used outside. That's what it is designed for, especially on RV's to heat outside to inside water line hookup. Any RV store sells this for that purpose or any other thing you want to use it OUTSIDE for. I use it all the time!
The cables use 7 watts pre foot ONLY when the thermostat calls for heat. If you insulate the pipe/cable then it will need to go on for less time so it effect it will average less than 7 watts/foot. So if it is on 10% of the time that 6ft cable will average 6 x 7 x 10% = 4.2 watts. Insulate don't cut!
Per the instructions in the packaging and at the Frost King website: Not for pipes over 1-1/2" in diameter. Must be wrapped with insulation to work properly SEE: https://www.frostking.com/wp-content/uploads/Pipe_heat_cable_trifold.pdf However, the instructions also say to contact them for larger diameters so the assumption would be they have a solution.
The heat cable is designed for locations where the temperature drops below freezing (e.g., attic). Also the length would be to long for a washing machine hose. So would not use.
Sure you can, but it will take longer to thaw
It will warm 2 feet beyond where the tape ends
The orange corded part is 36 inches. The black heater part is of course 6 ft.
I have quail (aprox 45) and use this product to freeze protect the supply water lines for my birds. I use a 35gal poly tank that gravity feeds a drip watering system that is heat traced and insulated. For your use you could use this product but you will need to heat trace & insulate the vessel plus use a GFCI. The birds like to pick at the insulation so keep that in mind. I would recommend using an immersion heater for the open pale to work or go to a closed drip watering system.
No, two cannot be spliced together.
I use it on the main pipe that brings water into my home. The sensor (the orange part with the black button) senses the cold and activates once it gets to a certain temp. so it won't work on a pipe that is already heated. Hope that helps.
