I dunno about using the electric heating cables normally used for on
house eaves and in gutters......Are they approved for submersion?
Being in ice or in a rain / sleet storm on a rood is not really
submerged. Same for outside extension cords, while they may work fine
in wet rainy weather, even with the plug ends out of water they sure
are not supposed to be submerged...... While I don;t have a dog in
this conversation in regards to having a pond in a potential freeze
situation, the use of a de-icing cable just spurs my interest in
regards to it being safe for such a use......
