If you often reheat and defrost meals, and would also like to bake in a single built-in appliance, a microwave combi oven is worth considering, provided its compact housing and settings suit your needs. If you mainly cook in the oven and have a housing designed for a 60 cm appliance, a fan oven is a more direct fit. According to the ADEME-INC summary, combi ovens have no general energy-efficiency advantage: results vary by dish, model and brand.
If you want to reheat and defrost food without a separate appliance, while still having oven cooking modes, take a look at built-in combi ovens. Check that their programmes and dimensions suit your dishes and kitchen unit.
If you mostly prepare roasts, gratins or bakes and don’t need a built-in microwave, focus on the cooking modes and capacity of a fan oven that fits your housing.
Measure the housing before choosing a type of appliance: a compact combi oven and a standard fan oven may have different heights. Then check the ventilation and electrical connection requirements in the instructions for the specific model.
Consider this if: oven cooking is central to your meals and your housing suits the model you choose.
Bear in mind: microwave reheating and defrosting aren’t built in.
Consider this if: you want to cook, reheat and defrost in one built-in appliance that fits your housing.
Worth noting: according to the ADEME-INC summary, efficiency varies by dish, model and brand, with no general advantage over a fan oven established.
| Criteria | What to check | Your needs |
|---|---|---|
| Cooking modes | Check whether it has a microwave-only mode, combination modes and programmes suited to your recipes. Also check which containers are suitable according to the instructions. | I want to reheat and defrost food without giving up oven cooking in the same space. |
| Cooking and energy use | Compare the features that are useful for your dishes and the energy label details for each model. The ADEME-INC summary finds no general energy-efficiency advantage for combi ovens: results depend on the dish, model and brand. | My usual recipes matter more than general claims about saving energy or cooking faster. |
| Installation | Compare the housing’s height, width and depth with the instructions, then check the ventilation and electrical connection requirements. Electrolux specifies a housing measuring 450 × 560 × 550 mm for the KVLAE2ST combi oven; these measurements don’t apply to every model. | My kitchen unit needs to fit the oven I choose. I shouldn’t assume that a similar front width means the height will be the same. |
| Cleaning | Check the cleaning system listed for the exact model number and consult its user manual. | I’d prefer to choose a cleaning method that suits how often I cook. |
The ADEME-INC summary says that efficiency varies by dish, model and brand; it doesn’t establish a general advantage for combi ovens over fan ovens.
Start with the way you usually cook, then check the settings and energy label of each model you’re considering.
Bosch, Siemens and Electrolux product specifications show compact appliances and standard ovens in different heights. A similar width alone doesn’t guarantee that an appliance will fit.
Measure the housing and compare all its dimensions, ventilation and connection requirements with the installation instructions for the model you choose.
A combination mode won’t guarantee the same result for every recipe. The ADEME-INC summary highlights that performance depends in particular on the dish and the model.
Check which modes are designed for the dishes you make regularly, along with the relevant instructions for use.
Bosch’s French product specifications let you compare a compact combi oven, the CMG7761B1, with a built-in fan oven, the HBG578ES7.
The CM776G1B1 is an example of a compact built-in microwave combi oven featured on Siemens’ French product page.
The KVLAE2ST is an example of a compact combi oven that combines microwave and oven cooking modes.
This Joybuy option is for cooking in a built-in fan oven; it isn’t a fan oven and microwave combi.

Consider this if you prefer oven cooking to a built-in microwave function. The product name indicates a 71 L capacity and 3D hot air function. Before buying, check the number of cavities, as well as the housing dimensions, ventilation and connection requirements for this model.
No. According to the ADEME-INC summary, efficiency varies by dish, model and brand, with no general advantage established for combi ovens. Compare the models’ features based on the dishes you actually cook.
Not without comparing the built-in dimensions. Electrolux specifies a housing measuring 450 × 560 × 550 mm for the KVLAE2ST combi oven, while the Bosch HBG578ES7 fan oven is 595 mm tall as an appliance. Measure your housing and check the instructions for your chosen model to confirm the ventilation and connection requirements.
First, check the installation instructions for the housing dimensions, ventilation and connection requirements, then make sure it has the modes you need for your recipes. ADEME also recommends checking the energy label to assess the appliance’s energy performance.
No. In France, the Ministry of the Economy states that the statutory guarantee of conformity is mandatory for goods sold by a business to a consumer, whether new, second-hand or refurbished. This right is separate from any additional commercial warranty offered.
