Buying an electric oven: how to choose the right size and features

An electric oven can be a practical addition to a student room, flat or family kitchen. However, making a quick choice is not always wise. A compact mini oven may seem convenient, for example, but could be too small for a standard oven dish. A spacious freestanding oven may not fit on your worktop. With a built-in oven, just a few millimetres’ difference can cause installation problems.

This buying guide explains what to look out for before you buy an oven. The selection is based on verifiable product specifications, such as capacity, dimensions, features, power and cleaning method.

Three common pitfalls when choosing an electric oven

1. Looking only at the number of functions

An oven with lots of programmes sounds appealing, but features you never use add little value. For everyday baking, top and bottom heat are often more important than a long list of automatic programmes. For pizza, bread and several baking trays, a fan oven may be more useful.

Also check exactly what each function means. “Turbo fan”, “3D hot air” and “convection” may be described differently from one model to another. Always check the official specifications rather than relying solely on the marketing name.

2. Confusing capacity with usable space

A 65-litre oven has more internal space than a 35-litre model, but the external dimensions and interior layout determine whether your baking trays will actually fit. Pay attention to:

  • the maximum diameter of an oven dish or baking tin;
  • the number of shelf positions;
  • the width and depth of the interior;
  • the position of the heating elements and fan;
  • the clearance required around a freestanding oven.

A 10-litre oven, such as the Rommelsbacher BG 950, is designed for small portions and baking trays up to 20 cm. That makes it practical for toast, muffins or a small pizza, but not for a family meal.

3. Assuming self-cleaning means no maintenance

An oven with a self-cleaning function still requires maintenance. Pyrolysis heats up residue intensely, after which you need to remove the ash. Hydrolytic or steam cleaning loosens dirt with water, but you will usually still need to wipe the interior by hand afterwards. An enamel or non-stick coating can make cleaning easier, but it does not prevent grease and food residue from building up.

Which electric oven is right for your kitchen?

Compact mini oven for small portions

A compact oven takes up little space and is suitable for students, single-person households and use as an additional oven. Pay particular attention to the temperature control, timer, door insulation and included baking tray. A grill oven with top and bottom heat may already be suitable for toast, small oven dishes and snacks.

Freestanding oven for a flexible setup

A freestanding oven sits on a stable, heat-resistant worktop and can be moved. Models with a capacity of 35 to 45 litres offer more room for oven dishes and pizzas. An oven with a grill function and fan setting is suitable for baking, roasting and browning. Beforehand, check that the socket and ventilation space are suitable for the stated power rating.

Spacious midi oven for families

An oven with a capacity of 60 to 70 litres is worth considering for larger meals, batch cooking and preparing several portions at once. According to the product specifications, the 65-litre Wiggo models have six cooking functions, five shelf positions and a power rating of 2000 watts. Do check the external dimensions: 60 cm wide, 49 cm deep and 40 cm high.

Built-in oven for a fitted kitchen

A built-in oven is installed in a kitchen cabinet. The standard size is often around 60 cm, but the niche height, width and depth must be checked precisely. The Bosch HBA571BB4, for example, has a niche height of 59.5 cm, a niche width of 56.8 cm and a niche depth of 55 cm.

Also consider the connected load. Built-in ovens rated at around 3,000 to 3,600 watts may have specific installation requirements. If in doubt, have the connection checked in accordance with local electrical regulations.

Important specifications to compare

Capacity and size

Use this guide as a starting point:

  • 10 to 22 litres: small snacks, toast and meals for one;
  • 30 to 45 litres: pizzas, oven dishes and everyday use for smaller households;
  • 60 to 72 litres: families, large dishes and several dishes at once;
  • around 70 litres: spacious built-in oven for a wide range of preparations.

Capacity alone does not tell you everything. Also compare the dimensions of the included baking tray and the available shelf positions.

Heating functions

A multifunction oven may offer different combinations of:

  • top heat;
  • bottom heat;
  • top and bottom heat;
  • fan cooking;
  • grill;
  • defrosting;
  • pizza or rotisserie programme.

An oven with fan cooking distributes hot air using a fan. This can be useful when cooking on several levels, but always follow the recommended temperature and cooking time in recipes. An oven with a grill function is suitable for browning dishes and grilling smaller portions.

Cleaning and energy information

Compare the energy label for built-in ovens and check the energy consumption per cycle where this information is available. The Bosch HBF133BR0, for example, states 0.98 kWh per cycle in conventional mode and 0.79 kWh in fan-assisted mode. Figures like these are more useful than general claims about energy efficiency.

Also check the cleaning method:

  • manual cleaning: simple system, but more cleaning work;
  • hydrolytic cleaning: water and heat help to loosen dirt;
  • EcoClean or catalytic coating: can help break down grease residue during use;
  • pyrolysis: an intensive high-temperature cleaning cycle.

Frequently asked questions about electric ovens

How many litres does an electric oven need to hold for a family?

For a small family, 35 to 45 litres is often sufficient. If you regularly prepare large oven dishes, pizzas or several dishes at once, consider a model with a capacity of 60 to 72 litres. In addition to capacity, check the dimensions of the baking tray and the available shelf positions.

How much does an electric oven cost to run?

Consumption depends on the power rating, preheating time, cooking temperature and duration of use. A 2000-watt oven does not use its maximum power continuously because the heating element switches off intermittently. For built-in models, compare the stated consumption per cycle and, where possible, use the oven fully loaded.

Can I place a freestanding oven directly on the worktop?

Only if the worktop is stable, level and heat-resistant, and the ventilation openings remain unobstructed. Maintain the clearance specified in the manual. Do not place the appliance close to curtains, paper or other flammable materials, and never leave a hot oven unattended.
