Buying an Oven: A Guide to Built-in Models, Combination Microwaves and Grill Solutions

A new oven should suit your kitchen dimensions, cooking habits and household energy consumption. In practice, however, it is not only technical differences that can lead to a poor purchase. Features that are rarely used in everyday life are often heavily promoted, while important details such as interior dimensions, connection requirements and cleaning effort receive less attention.

This guide from the Joybuy Product Recommendation Officer provides an objective overview of the key features and shows which appliances suit different usage profiles.

Common pitfalls when buying an oven

1. Too many functions without enough space

A multifunction oven can combine, for example, conventional top and bottom heat, fan-assisted cooking, a grill and a pizza function. However, the crucial question is whether you have enough space. A built-in oven measuring 60 cm wide will not automatically fit every kitchen aperture. Before buying, compare the niche width, niche height, depth and position of the power connection with the manufacturer's specifications.

With a combination microwave, you should also check whether it is freestanding or designed for built-in installation. Appliances with a convection function require sufficient clearance for ventilation.

2. Confusing the energy class with actual consumption

The energy efficiency class, such as energy class A, is a comparison value within the applicable labelling system. Actual consumption also depends on the temperature, operating mode, preheating and usage time. An energy-efficient oven can be a sensible choice if you frequently use fan-assisted cooking or ECO mode, but it does not replace checking the specific consumption figures on the energy label.

3. Overestimating cleaning systems

A steam or AquaClean function can soften residues. It normally does not replace removing baked-on grease, cleaning accessories and wiping the door. For heavy soiling, a suitable oven cleaner may be necessary. Chemical cleaners should only be used in accordance with the instructions on the packaging and appliance. Gloves, good ventilation and thorough cleaning afterwards are important.

Technical details to check before buying

Interior and features

Capacity is stated in litres. A 70-litre oven provides more room for large roasting dishes or several shelves than a 20- to 25-litre appliance. For smaller households, however, a microwave with grill may take up less space.

You should also look at:

  • Number and position of shelf levels
  • Dimensions of the baking tray, wire rack and turntable
  • Grill power and included grill accessories
  • Timer, display and automatic programmes
  • Child lock and ECO mode
  • Type of cleaning system and removable accessories

An oven with grill function is suitable for topping dishes with cheese and browning food. A pizza function is practical if the temperature control and suitable accessories match your cooking style. With a combination microwave, it should be clear whether a genuine convection function is also included. This is what distinguishes a basic grill microwave from an appliance with fan-assisted or convection cooking.

Connection, ventilation and safety

With an electric oven, you need to consider the mains voltage, connected load and requirements for the electrical connection. Built-in appliances should be installed professionally if the connection is not clearly designed for the intended operation.

Freestanding microwaves need air circulation around them. The Sharp YC-MG01E-B, for example, is specified as having a 20-litre capacity, 800 watts of microwave power, 1,000 watts of grill power and five power levels. Such figures should always be considered in relation to the available worktop space and frequency of use.

For microwaves, the rule is simple: metal containers, unsuitable foil and sealed containers must not be placed in the cooking chamber when using microwave mode. In grill mode, metal accessories may only be used if the instruction manual expressly permits this.

Materials and care

Smooth interior surfaces make wiping easier, but they do not automatically prevent baked-on residues. Cleaning pads such as the abrazo Pot & Pan Cleaning Pads may be suitable for pots, grill racks and robust kitchen utensils. Before use, check whether the surface is susceptible to scratching.

Outdoor applications involve additional requirements. A BBQ grill with smoker should have adjustable air vents, an easy-to-read thermometer and sturdy, heat-resistant components. The appliance must be placed on a level, sufficiently ventilated surface away from easily flammable materials.

Cleaning and additional accessories

For baked-on residues on suitable, cooled surfaces, the Bref Power Oven & Grill Cleaner 500 ml can be used. According to the description, the product is intended for ovens, grills and BBQ surfaces. Beforehand, check any delicate coatings, seals and the manufacturer's instructions.

If you are furnishing a smaller kitchen, you could also consider the Bauknecht MWK 253 B, with a 25-litre capacity, 900 watts, seven power levels and grill function, or the compact Sharp YC-MG01E-B, with a 20-litre capacity. However, the two appliances differ in terms of convection cooking, controls and features. Comparing the specifications directly helps ensure you do not pay for a function you do not need.

Frequently asked questions about ovens

What size oven is suitable for a household?

For families and regular baking, 60 cm built-in appliances with a capacity of around 60 to 70 litres are often a good choice. Smaller households can manage with 20 to 25 litres, particularly if a combination microwave is mainly used for reheating and preparing smaller portions.

How much does it cost to run an oven?

The cost depends on the power rating, operating mode, temperature, preheating time and usage duration. As a guide, multiply the power in kilowatts by the operating time and your personal electricity tariff. The information on the energy label enables a more objective comparison than broad advertising claims.

How long does an oven last?

A specific service life cannot be guaranteed in general. It depends, among other things, on frequency of use, cleaning, maintenance and the quality of the components. Regularly wiping the appliance, keeping the ventilation openings clear and following the instruction manual can help support proper operation.
