Our INT31NT 30cm induction domino hob adds a new dimension of cooking to any kitchen. General Specification Whether you are looking to make the best use of space and opt for a two zone hob rather than a four or five zone, or if you are simply looking to add more zones to your kitchen, our induction domino hob offers the perfect solution. Each cooking zone has a 99 minute timer so you can simply set it and relax. Induction Technology Induction technology means that the pan* is heated directly rather than wasting energy heating the cooking surface. As a result of this, food heats up quickly and there is little residual heat from the cooking surface. *Pans must have a high iron content due to induction working on magnetism.
