A halogen hob (also known as a halogen cooking zone ) is a hob in which the cookware is heated by infrared radiation .
Underneath the hob, which is usually made of glass ceramic (e.g. Ceran ), there is a heating coil in which a glass tube filled with halogen is accommodated. This emitter generates short-wave infrared rays. In principle, the halogen hob works like a halogen light bulb . While a halogen incandescent lamp shines at 3,500 K, a halogen hob does so at 2,500 K. About 10% of the energy is visible light , which is why the heating coil under the transparent glass plate appears reddish. The rest is infrared radiation that passes through the glass hotplate.
Often, combinations (semi-halogen) of halogen heaters and conventional radiant heaters (free radiating heat conductors) are offered as halogen cooking zones.
Comparison with other hobs
Compared to a conventional cast iron hotplate, the halogen cooking zone has a shorter reaction time when the settings are changed, which shortens the preheating time and enables quicker and more easily dosed searing. Compared to an induction hob , the halogen cooking zone has the advantage that no special cookware is required.
A disadvantage of the halogen cooking zones compared to conventional hotplates is their high cost. In comparison to the induction hob, the worse reaction times are to be mentioned. Burning things off the hob is more difficult and is often said to leave scratches.
In terms of energy efficiency , the halogen hob is better than a cast iron hob, but worse than an induction hob.
