why does heating coil not produce any visible light?

Put enough electrical energy into it and it surely will.
As objects heat they emit increasing amounts of Infrared; at a critical temperature atoms will start to produce a first order harmonic - i.e red light. With increasing energy, the statistical population of atoms emitting red light will increase until the object glows bright red.
Push in even more energy and you add a second order harmonic one musical fifth above red light - this light is green. Add to the red light and you now have orange. With increasing energy, the statistical population of atoms emitting both red and green light will then increase until the object is bright yellow.
Push in yet more energy and a third order harmonic is added; this is one musical octave above red; this light is blue. Eventually, you will be pushing in sufficient energy that the object glows brilliant white.
That's how a light bulb does it. However, a heater coil has been designed so that under normal operating conditions it will only produce Infrared

Answer:
It does not produce visible light because the heat radiations do not match the frequency of the visible light
