Using Electrical Resistance Wire Outdoors
Electrical cords are not meant to be used for heating. They may warm up a little under load but if they should get very warm they will be unsafe.
You can get roof heating cables (normally installed zigzagged at the roof eaves) and lay them where you want; you leave them uncovered.
You can get heating strips intended for such purposes as keeping pipes from freezing or for thawing them; the instructions suggest what (if any) kinds of insulation are safe for wrapping the pipe after you put the strip on the pipe.
Both of these heating items plug into extension cords, usually heavy duty cords are needed.
Do not string bare resistance wire such as Nichrome about the place.
The disadvantages of crab apple trees. In summer, the apples are too sour to pick and eat. In winter the birds come and leave dropping all over the place.
