With a Siemens 45cm oven, you can prepare meals in no time. The models from the IQ500 series preheat fast, so you can put your dish in the oven quickly. The models fit in a 45cm niche height. Don't want to scrub the oven in the weekend? Choose a model with pyrolysis. This burns the grease and dirt at a high temperature. If you make large portions of food and reheat them regularly, a combi oven suits you. In a Siemens combi steam oven, you can prepare your entire meal with steam.
