Product Description
Product Overview:
The Bosch HNG978QB1A is a premium 60cm built-in combi steam oven from the Bosch Series 8 collection, finished in Carbon Black glass with integrated microwave functionality. Combining conventional oven cooking, steam assistance, microwave cooking and assisted automatic programmes within a single appliance, it is designed for kitchens seeking advanced multi-function cooking flexibility without separate steam or microwave appliances.
The 67L oven cavity incorporates Bosch’s 4D HotAir system for even heat distribution across multiple shelf levels, while integrated steam support assists with moisture retention during roasting, baking and reheating. Microwave combination cooking reduces cooking times by combining microwave energy with traditional oven heating methods. The appliance also features Bosch’s Air Fry functionality with a dedicated Air Fry & Grill tray for crisp cooking results with reduced oil usage.
Bosch’s Series 8 cooking assistance technologies include PerfectBake Plus, PerfectRoast Plus and Individual Browning with integrated camera functionality. The TFT Touchdisplay Pro interface with Digital Control Ring provides touchscreen operation with guided programme selection, while Home Connect enables remote access, recipe integration and appliance monitoring through compatible smart devices.

Extra Information:
The HNG978QB1A combines multiple appliance categories within a single built-in cavity, reducing the requirement for separate steam ovens or dedicated built-in microwaves. Bosch’s inverter microwave technology provides more consistent microwave energy control during lower power operation compared with conventional pulsed microwave systems.
The integrated oven camera supports Bosch’s Individual Browning functionality through Home Connect compatible devices, allowing users to monitor browning levels remotely and automatically stop cooking once the selected browning result is achieved.
The pyrolytic cleaning cycle locks the oven door during operation while heating the cavity to extremely high temperatures, reducing food residue to ash which can be wiped away after cooling. HydroClean assistance may be used between pyrolytic cycles for lighter cleaning maintenance.
