How to Choose a Built-In Oven in 2026: Complete Guide (Multifunction, Litres, Cleaning and Energy Use)

Changing your oven is one of those purchases you make once every ten or fifteen years, so it pays to get it right. At Híper Ocio, in Albox, we have been selling and fitting appliances in kitchens across the Valle del Almanzora since 1923, and the oven is one of the products that raises the most questions: how many litres do I need? Is a fan oven worth it? What is this built-in air fryer? And what about the pyrolytic cleaning you see in the adverts?

This guide is meant to help you arrive at the shop (or write to us) knowing exactly what you are looking for. No marketing smoke: we explain what a shopkeeper really looks at when advising on an oven, with real models that we stock or work with at Híper Ocio, their prices and who each one suits. Most of them are 60 cm built-in ovens, the standard size in Spanish kitchens.

An important note before we start: we deliver and fit built-in ovens and the rest of our white goods ourselves, with our own van, in the Almanzora area, the Levante almeriense and Los Vélez. We do not ship large appliances nationwide, because we prefer to leave them installed and working. For toys and small appliances we do ship across Spain.

Updated in August 2026. We have checked prices and availability, and we have added a clarification on energy labelling that causes constant confusion at the counter: ovens still use the old A+++ to D scale, while dishwashers were relabelled to the A-G scale in 2021. So seeing a dishwasher rated "class E" does not mean it is a bad one: the new scale was deliberately redrawn to leave room at the top. We go into it in our guide to choosing a dishwasher in 2026, useful if you are renovating the whole kitchen and want to match oven, hob and dishwasher in the same finish and with the same delivery.

First things first: measurements and the built-in recess

Before falling for any model, measure. 95% of the built-in ovens we sell are 60 cm wide, which is the size of the standard recess in kitchen units. What changes between models is the depth and, above all, the cut-out size of the recess (the inside height and width of the unit), which is given in each oven's manual.

Points worth checking before you buy:

• Width: 60 cm is the norm. There are compact 45 cm-high ovens for tall units, but they are a minority.
• Ventilation: the unit needs an air gap underneath and behind. If the recess is very tight, mention it before buying.
• Electrical connection: an oven needs a socket with enough amperage. If your installation is old, it is best to have it checked by whoever will fit the oven.
• Separate oven or under-hob: today almost all ovens are independent of the hob, which lets you combine an oven from one brand with a hob from another.

This is exactly the kind of detail where buying from a shop with its own installation service helps: we come, measure and leave it fitted, with no last-minute surprises.

Cooking functions: fan oven, grill, turbo and air fryer

This is the heart of an oven. Do not be dazzled by the number of programmes: what matters is understanding the basic functions and using them well.

• Conventional heat (top + bottom): the traditional one. Perfect for sponge cakes, bread and roasts on a single tray.
• Convection / hot air: a fan spreads the heat around the whole interior. It lets you cook on several trays at once with even results and usually shortens cooking times. It is the function you will miss most if you do not have it.
• Grill: intense heat from above for gratinating, browning and giving meat and vegetables a final crust.
• Turbo (grill + fan): combines the grill with the fan for roasts that are juicy inside and golden outside.
• Built-in Air Fryer: the novelty of recent years. The oven circulates air at high speed to give an "air fryer" effect with far less fat, but with the capacity of a full-size oven.

A concrete example: the Infiniton B698 stainless steel oven (around €229) has 8 cooking functions, including turbo convection and the grill + turbo combination, with energy rating A. It is a complete multifunction oven at a very contained price, ideal if you cook often without wanting to overspend.

Capacity: how many litres do I need?

Capacity is measured in litres and tells you how much fits inside. As a practical guide:

• Under 60 L: compact ovens, for small flats or second homes.
• 60-70 L: the sweet spot for most families. A whole chicken, a standard baking tray and a family lasagne fit comfortably.
• Over 70 L: for those who bake a lot, cook for many people or want to use several levels at once.

In our selection, the Infiniton CB6516 65-litre (around €229) is the classic good-value choice: stainless steel, convection, grill and a 56 × 32 cm tray included. If you want something bigger, the Infiniton CA6516 70-litre (around €259) adds capacity and 8 functions. And at the top end, the Balay 3HB5131N3 71-litre (around €359) offers 71 L, elegant black glass, a double-glazed door and A+ efficiency.

Cleaning systems: pyrolysis, hydrolysis, catalytic and easy-clean enamel

There is a lot of confusion here, so let's be clear. There are four main ways of keeping the inside of an oven clean, from the most automatic to the most manual:

• Pyrolysis: the oven heats up to around 480-500 °C and turns all the residue into a fine ash that you then wipe away with a cloth. It is the most convenient, but it makes the appliance more expensive and uses quite a lot of electricity on each cycle.
• Hydrolysis (or aquolysis): you pour water into the base of the oven and, with gentle heat (around 90 °C), the steam softens the dirt so it comes off easily. It uses much less than pyrolysis.
• Catalytic: porous panels on the walls absorb grease while you cook and break it down with the normal cooking heat.
• Easy-clean enamel: a smooth enamelled interior where residue does not stick hard and comes off with a damp cloth. It is what most mid-range and budget ovens have.

Let's be honest: most of the ovens we usually stock at Híper Ocio, such as the CB6516 or the Infiniton DualDial DD13SA (around €299), use an easy-clean enamel interior, not pyrolysis. For a family that cleans the oven regularly, it is more than enough and saves money both at purchase and on the bill. If you really want a pyrolytic oven, tell us and we will find it for you: we work with Balay, Beko and Infiniton and can order the self-cleaning model you need.

Energy use and energy label: what you really need to know

One detail that confuses many people: ovens have NOT been relabelled, unlike fridges, washing machines or dishwashers. While those appliances moved to the new A to G scale, the energy label on ovens still shows the old rating, from A+++ (the most efficient) down to D. On the market today you will mostly find A+++, A++ and A+ ovens and the occasional B; the B models are the least efficient ones on sale.

The label gives the consumption (in kWh) in two modes: fan-assisted and top-and-bottom heat. In practice, a modern oven rated A or above uses little per cook, and what weighs most on the bill is how long you have it on and at what temperature. Shopkeeper's tips for spending less: use the residual heat by switching off a few minutes early, do not preheat more than needed, cook several things at once with the fan, and avoid opening the door all the time (every opening drops the temperature and lengthens the cooking time).

Ovens with Air Fryer: fad or good choice?

The air fryer built into the oven has become fashionable, and with good reason: it lets you get crispy chips, wings or vegetables with up to 90% less fat, but with the space of a full oven instead of one more gadget taking up the worktop.

If this function interests you, the Beko BBIMA13300XS (around €329) is a 72-litre multifunction oven with Turbo and built-in Air Fryer, 10 functions, a range of 35 to 275 °C and a low-consumption black stainless finish. For a family that wants to modernise the kitchen without filling the cupboards with gadgets, it is a very well-rounded purchase.

Oven and built-in microwave, matching

If you are renovating the whole kitchen, it is worth thinking about the set. Placing the oven and a built-in microwave in a column, one above the other, looks very clean and frees up the worktop. The trick is for both to share the same finish (stainless, black) so the front looks harmonious.

An example that goes well with our stainless steel ovens is the Infiniton IMW-SS25L 25-litre built-in microwave (around €229), in Dark Inox with quartz grill. If you would rather have it in black to match a dark oven, we also work with other finishes: ask us and we will fit the combination.

Our real selection by budget

To sum up, this is our honest recommendation according to what you are looking for and what we stock in the shop (indicative prices; ask us about availability, because we order white goods on demand):

• Best value (basic multifunction): Infiniton CB6516, 65 L, stainless steel, grill and convection: around €229.
• More functions without spending much more: Infiniton CA6516, 70 L, 8 functions: around €259.
• Full turbo: Infiniton B698, 8 functions, class A: around €229.
• Design and a trusted brand: Balay 3HB5131N3, 71 L, A+, black glass: around €359.
• With built-in Air Fryer: Beko BBIMA13300XS, 72 L, 10 functions: around €329.

All of them are 60 cm built-in ovens, so they fit the standard recess in most kitchens. If you are unsure which one suits your unit best, come into the shop with your measurements and we will look at it together.

Frequently asked questions about built-in ovens

Which is better, a pyrolytic oven or an easy-clean one?

It depends on how much you value convenience. A pyrolytic oven cleans itself by burning off the residue at high temperature and is the most convenient, but it costs more and uses more electricity on each cycle. Easy-clean enamel, which most mid-range ovens have, is more than enough if you clean the oven regularly and it saves you money.

How many litres does a family need in an oven?

For a standard family, 60 to 70 litres is the ideal range: a whole chicken, a baking tray or a family lasagne fits. Under 60 L is for small flats; over 70 L is for those who bake a lot or cook for many people.

Is an oven with convection or hot air worth it?

Yes. Convection spreads the heat evenly and lets you cook on several trays at once with good results, as well as shortening cooking times. It is the function you miss most when you do not have it, so we recommend it almost every time.

Do ovens use the new A to G energy label?

No. Unlike fridges, washing machines or dishwashers, ovens have not been relabelled and still use the old scale, from A+++ (the most efficient) to D. On the market you will mostly find A+++, A++ and A+ models and the occasional B.

Do you install the oven at home?

Yes. We deliver and install ovens and the rest of our white goods with our own van in the Almanzora area, the Levante almeriense and Los Vélez. We do not ship large appliances nationwide because we prefer to leave them installed and working.

Can I combine an oven from one brand with a hob from another?

Yes. Today almost all ovens are independent of the hob, so you can choose each appliance separately. You only need to make sure the built-in measurements fit your unit; we are happy to check it with you.
