Question

Power supplied to maintain wire temperature at 110 in water bath of 100

Answer 1

I am a complete newbie to anything electrical/electronics. I am doing a project where I need to heat a 1 km long (Nichrome/Kanthal) wire to up to 110 degree Celcius. The only power supply available is 12V from car cigarette lighter. Can someone explain what is the best way to attain this using the available resources please.

Thanks for your replies.

Thanks for your replies. I am intending to weave the wire onto a fabric which can easily withstand over 200 C. The wire will be in a continuous forms and the purpose of the wire is to heat all of the fabric. Imagine a blanket that is covering the back seat. something similar to heated car seats, but much hotter. It will only be used inside the car.

I could possibly connect the wires in parallel, but is not preferred due to the work involved. The thickness of the wire can be anywhere from 0.3 to 0.6 mm. Any thicker or thinner is not practical to lay into fabric. The 1 km of wire will be laid with in a 2-3 square meter of fabric.

By the way, this is to heat the whole car (atleast passenger area) so that the kids can sit in a warm car, rather than a cold car.
