Can i heat a wire to above degrees with a low cost battery source

[Asare]

Firstly i need to heat a wire to around 20 degrees or over using a low power battery which could last up to 24hours.

what kind of wire is easiest to heat up?

would AA battery's work?

what would be a long lasting battery source?

can it be done?

please help me!

thanks

You need wire with high resistance, or you could also put resistors in parallel circut.
What do you want to do with such wire?
Nichrome V is one of wires that has high resistance.

i need the wires to keep an outdoor component above 10degrees or at room temperature during winter months. i was planning to use a thermistor to activate the heat when the temperature drops below a certain point. do you recon a battery source can keep the wire heated for up to 24hours?

Oh well, it would be pain in the *** honestly, It does not matter what battery you use, it will run out pretty fast, so you would need to buy them every day, it's just the higher the voltage, the faster heating element will heat up. Thermistor would definately work for fast heat up, but your wires will keep getting hotter and hotter draining remaining inch of battery power.

You should get heating cables, there's nice operating display to set temperature and to keep electrical costs down, it would pay itself off after about one month compared to buying batteries every day.

There's that company called Devi, there are many different heating cables with reasonable price, they supply most of the world(US & EU)

Good luck.
