I want to make a low temperature (<30C), low wattage (<30W) heater for keeping wine warm enough during fermentation in a cool room.
I thought about using common green plastic covered garden wire. Since it's the current through a resistance which generates the heat, would there be any disadvantage to using iron instead of copper? It would be temperature controlled and I can't see any problems but maybe you can.
