The simple, yet stylish frameless design of the Bosch PIE675N14E induction hob makes a smart addition to your home. 4 powerful zones provide fast and efficient heat for quick cooking results. Ultra-efficient induction works by creating a magnetic field between the hob and steel or iron pan. The heat is instant, easily controlled and energy efficient. 17 variable heat settings for each zone make it easier to control your cooking and 2 stage residual heat indicators provide a clear indication of when a zone is still hot after it has been turned off. There are 2 levels - "H" if there is sufficient heat to continue cooking and "h" if there is insufficient heat to cook with, but it's still hot enough for caution. There’s also a timer for each zone, so you can set the zone to heat for a specified time and it will switch itself off afterwards. The DirectSelect feature allows you to choose the heat setting straight away without having to move through the range and what ’s more, a power management function keeps you in control of your cooking session. A power boost function is on hand for an extra burst of heat and a handy control panel lock function provides peace of mind. Note: Only use pans suitable for induction hobs. These include: enamelled steel, iron, stainless steel (depending on the alloy) and some aluminium pans with a ferromagnetic base. Glass and copper bases are unsuitable.
