Thanks for your suggestion, I will definitely look into it. and I was wondering, what if I reduce the length to 10 meters instead? could you tell me the specs of the wire in that case?

I think the loss is going to be small since I am trying to heat up a sheet of woven polyester that will sit on a wall to prevent it from getting frozen. it's whole purpose is to melt the snow off that sheet

Hello, I have an 80-meter nichrome wire and I want it to heat up to 40 degrees Celsius maximum (30 to 40 is ok). I want to connect it to a battery that is enough to make it hot for at least 10 hours. The ambient's temperature is negative 15 degrees Celsius. What is the diameter for this wire? what is the resistance? What are the spec of that battery in this case?
