Siemens built-in microwaves come in two types. Compact combination ovens can grill and bake as well as microwave, and microwave-only models handle reheating and defrosting. Both types come in the iQ500 and iQ700 series. The iQ700 models have TFT displays, and the iQ700 combination ovens can also connect to the internet.

The Siemens built-in combi microwaves have 44 to 45 litres of gross capacity and a drop-down door, like a compact oven. Each one can pair microwave power with grill or convection heat. That lets you brown a gratin or bake faster than with conventional heat alone, so a combi works well as a second oven. Cleaning differs between models. Some use humidClean, which vaporises soapy water to soften dirt so you can wipe it away. Two iQ700 models add pyrolytic activeClean, which heats the cavity to a high temperature and turns grease to ash.

The Siemens built-in microwave ovens are smaller, at 20 to 25 litres, with 800 W or 900 W of microwave power. Each has a left-hinged door that opens with a button rather than a handle, which suits fitting at eye level. The iQ500 models have seven automatic programmes. Cleaning varies by model: manual wipe-clean, humidClean or hydrolytic.

Start by deciding whether you want a second oven or a dedicated microwave. If you plan to grill or bake, choose a combi. If you'll mostly reheat and defrost, a microwave-only model takes up less space. Then compare cleaning methods and decide whether app control matters to you.
