Two innovative features that deliver HD Cooking performance. The patented Direct Flame technology is delivered via the revolutionary design of the new burners. Each burner consists of a single piece cap, covered in 420 tiny, carefully arranged holes. The flame burns directly upwards through these micro-perforations in a completely uniform manner. While the Flexizone feature goes one step further, intelligently detecting the position and size of your pan, whether it's a small cafetiere or a large fish kettle and heating the hob accordingly. The results - perfectly even heat distribution for High Definition results.
