I'm trying to figure out what temps I can get and how wire gauge and length effect temp. I need a low temp heating element anything from 25 - 100 C.

I calculated that

26g - 25ft = 1 ohm

24g - 39ft = 1 ohm

The thing is that I don't know how to calculate what wire to use to try this and if I can add a pot or resistors to change the temp.

I have 17, 24, 26, 28 & 30g copper wire that I can try with this.

Can anyone point me in the direction to figure this out or give me some insight into this?

I just calculated the wire parameters and it says that a single 24g wire would draw 3.18 amps. If I apply 12v then I should get about 38.16 watts - or about 1 watt per foot. What I am not sure of is how resistance comes into play here.
