Heating element or furnace

[iafshin]

There is a big feature in this game that allowing us to convert materials together (like fertilizer to dirt or ... ) which needs high temperature and we can't use space heater because of low overheat value . now only thing we have is lava, but if you heat it more then that you will get tungsten almost 4000c . we can make tungsten from even steam(with ONI logic's), and that is a unlimited resource for very late game. i think this device should have 5000c overheat value and should be like space heater or integrated into a isolated tile because not getting damage from itself heat and it wire doesn't get hot. this system also need two isolated door for intake and outlet and some automation(heat resistor automation).
