A powerful, stylish and functional addition to your kitchen, with four heat zones and 9 power levels, you're guaranteed quick and consistent cooking. Designed with simplicity in mind this all-black glass hob will look good in any kitchen. Advanced heating Ultra-efficient induction heating technology works by creating a magnetic field between the hob and steel or iron pan. The heat is instant, easily controlled and energy efficient, localising temperature for efficiency and perfect cooking results. Touch Control Front location touch controls give this John Lewis hob a contemporary feel, while also having the advantage of being very easy to clean. Once the temperature is set, you can lock the control panel for extra safety and it will automatically switch off if a large spillage occurs. Safety controls With the Child Lock you can make sure little hands are prevented from adjusting the controls, giving you complete peace of mind. Residual Heat Indicators are an invaluable safety feature. The indicators light up to tell you if the surface of a ceramic hob is still hot, even after you have turned off the controls. Please note: If you have a heart pacemaker, do seek advice from your doctor before using an induction hob.
