The HR 612 CH built-in Ceramic Hob from Hotpoint, in a stylish & contemporary black glass finish, measures just under 60cm in width & has four cooking zones. Easy touch controls give you precise temperature control. It has a Double Ring Zone, which is a dual zone that increases cooking flexibility so the hob can be used for various pan sizes & power levels. There are nine power levels to choose from, so you can choose the perfect power level for the food you're cooking. For safety, there are residual heat indicators where the indicator lights stay on until the surface has cooled down to a temperature which is safe enough to touch. For extra safety, the heat controls cannot be adjusted or switched on when the child lock function is activated, which gives peace of mind should your children be able to access the hob. Please note: there should be a minimum height clearance of 65cm between an electric hob & the cooker hood above it.
