Built-in ovens: which functions you will actually use

An oven's feature list reads just as impressively at every price. The trouble is that half of it is wanted twice a year, while two or three functions decide everything. Here is a calm look at what the mode names actually mean, and at what to weigh once the kitchen is designed and only the oven is left to choose.

Heating modes

The basic set is top heat, bottom heat, the two together and convection. Top and bottom together is the classic for baking that likes steady, still heat. Convection adds a fan that evens the temperature across the cavity: that is what lets you bake on two shelves at once and shortens the preheat. Bottom heat on its own rescues tarts with a wet filling whose base otherwise stays pale.

Grill and steam

The grill is a more powerful top element; paired with the fan it behaves like fan-assisted roasting and browns evenly without turning the tray. Steam is a category of its own: an oven that keeps moisture in the cavity gives bread a better crust and dries out a joint of meat less. If you bake bread or often cook large cuts, that is a function you will reach for regularly.

Automatic cooking programmes deserve a separate word. They help at the start, before you have a feel for your own oven, but most people drift back to a manual mode with convection and a probe. Treat them as a hint rather than as an argument for a more expensive model. Something much simpler will matter more often: even lighting inside the cavity and glass you can genuinely see through, so a dish can be checked without opening the door and dropping the temperature.

What to look at besides the modes

• cavity volume and the number of shelf levels, measured against your trays rather than the brochure;
• telescopic runners, which let a hot tray come out without acrobatics;
• a food probe, if you cook meat and would rather watch the core temperature than the clock;
• the cleaning system: catalytic liners, hydrolytic cleaning or pyrolysis — the last of which wants its own supply;
• the number of panes in the door and a cool front, if there are children in the house;
• the controls: mechanical knobs are simpler to repair, touch panels simpler to wipe.

About the installation

An oven is far more comfortable in a tall unit at chest height than under the hob: no bending, and a hot tray travels in a straight line. Check the ventilation gaps given in the instructions and the cable cross-section: a built-in oven is a powerful appliance, and its supply is planned separately while the wiring is still open.

The practical conclusion is short: choose by the heating, by how usable the cavity is and by the cleaning system, and treat the long list of exotic programmes as a bonus. Those three things are what you will feel every week for the next ten years.
