With the Siemens HB634GBS1, you'll get yourself a spacious, versatile built-in oven with 7 preparation systems. In addition to upper and lower heat, you'll also have a hot air and grill function at your disposal. This way, you can easily prepare large or multiple meals simultaneously, or you give your lasagna a crispy layer of cheese. With the 5 rack levels, there's plenty of space to prepare the appetizer, main dish, and dessert at the same time. Done cooking? The oven turns off automatically. This prevents your food from overcooking and keeps your oven from getting overheated. Your children are also safe while you're baking: thanks to the cool front and child safety lock, the oven stays cool on the outside and your little ones can't open the door.
