BOSCH HQA334EB4 Serie 4 oven with added steam function
The BOSCH HQA334EB4 Serie 4 built-in oven features an added steam function that ensures perfect baking for bread and other dishes. The gentle steam prevents food from drying out, creates a deliciously crispy crust, and keeps the inside fluffy and juicy. Simply fill the removable water bowl, located at the bottom of the oven cavity, and select the 'hot air + steam' programme. This makes all baked or roasted dishes tastier and perfectly cooked.
Hotair Steam for perfect roasts
The BOSCH HQA334EB4 Serie 4 built-in oven uses Hotair Steam technology, which evenly distributes heat and moisture throughout the oven cavity. The result is food with a perfectly crispy crust on the outside and a soft, juicy centre on the inside. This technology guarantees perfect results every time you bake, whether you're preparing bread, meat, or other delicious dishes.
BOSCH HQA334EB4 Serie 4 oven with a clear LED display
The BOSCH HQA334EB4 Serie 4 built-in oven is equipped with an LED display that makes it easy to set all the oven's functions. It gives you full control over the temperature, heating type, and cooking time. The modern time functions also let you plan the cooking process precisely, so every meal will be prepared exactly as you wish.
3D Hotair ensures even baking on multiple levels
The 3D Hotair function in the BOSCH HQA334EB4 Serie 4 built-in oven lets you bake on up to three levels at once. Heat is distributed quickly and evenly throughout the interior, so biscuits, lasagne, or muffins are always perfectly baked. The BOSCH HQA334EB4 Serie 4 oven also lets you prepare two different dishes at the same time without their aromas or flavours mixing.
Elegant retractable dials
The BOSCH HQA334EB4 Serie 4 built-in oven offers elegant retractable dials that combine comfort and modern design. A simple turn makes it easy to set the heating type and temperature, while the smooth surface of the dials simplifies maintenance and cleaning. It’s a practical and elegant solution that makes using the oven a pleasure every day.
CleanCoating ensures economical and easy cleaning
The economical CleanCoating cleaning system makes oven maintenance easier. A special coating of micro-fine ceramic spheres on the back wall breaks down grease splatters during baking or frying. This contributes to easier cleaning throughout the appliance's use.
BOSCH HQA334EB4 Serie 4 with Cleaning Assistance for quick and efficient cleaning
Got a lightly soiled oven that needs a quick clean? Simply pour about 400ml of water with a drop of detergent onto the bottom of the oven cavity. Then set the bottom heat to 80°C and the timer for 4 minutes. The smart cleaning assistance softens baked-on residue, which you can then easily wipe away. The result is quick and effortless oven cleaning.
Energy efficiency class A+ for economical cooking without compromise
Bosch built-in ovens achieve an A+ energy efficiency rating. Optimised airflow, improved oven materials, and more effective insulation contribute to reducing energy consumption during cooking and baking.
