Microwave Buying Guide: Avoiding Costly Mistakes

Shopping for a new microwave can quickly become overwhelming. Manufacturers advertise high wattages, countless automatic programmes, and innovative designs. But not every feature is worth the extra cost. Many buyers fall into common traps, leading to an unsuitable appliance or unnecessary expense. This guide will help you cut through the noise and make an informed decision.

The 3 Most Common Traps When Buying a Microwave

1. The Wattage Trap: A high wattage (e.g., 1000W and above) is often promoted as a mark of quality. However, for everyday use like heating food or defrosting, 700 to 800 watts is perfectly sufficient. Higher power is only relevant if you plan to regularly cook complex dishes in the microwave.
2. The Capacity Illusion: A large volume in litres doesn't automatically mean more usable space. An awkwardly positioned turntable or a curved interior wall can severely restrict the effective area, preventing square dishes from fitting inside. Therefore, pay attention not only to the litre specification but also to the usable interior dimensions and the design of the cavity.
3. Superfluous Extra Features: Dozens of automatic programmes for yoghurt, pizza, or cake sound tempting but are rarely used in daily life. Every additional function drives up the price. Honestly consider whether you truly need more than the core functions (heating, defrosting, and perhaps a grill).

What Really Matters: The Key Criteria

Before you decide on a model, three fundamental parameters should be clear. These determine whether the appliance fits your needs and your kitchen.

1. Form Factor: Freestanding or Built-in?

Choosing the form factor is the first and most important decision.

• A freestanding microwave offers maximum flexibility. It can be placed on any worktop or shelf and is easy to take with you when you move. These models are often more affordable and available in a wide variety.
• A built-in microwave is seamlessly integrated into a kitchen cabinet, creating a cohesive, clean look. This requires precise measurement of the existing cabinet space. Installation is more complex, and the appliances are generally more expensive.

2. Cavity: Capacity and Turntable Technology

The cavity capacity, specified in litres, should match your household size.

• Up to 20 litres: A compact microwave with a cavity of up to 20 litres is ideal for singles or couples. It is sufficient for standard plates and small casserole dishes.
• 20 to 25 litres: This is the most common size for families. It offers enough space for larger plates and most ready-made meals.
• Over 25 litres: Large appliances are suitable for households that use the microwave intensively or often cook for several people.

An often-overlooked aspect is the turntable. A microwave without a turntable (with a flat ceramic base) offers a completely flat surface. This allows for the use of square casserole dishes and maximises the usable space.

3. Features: From Solo to Combination Models

The range of functions determines what you can do with the appliance.

• Solo microwave: This is the basic model, designed for heating, cooking, and defrosting food. It is the most straightforward and affordable option.
• Microwave with grill: An additional grill function allows for browning and gratinating dishes like casseroles or pizza. A quartz grill heats up faster than conventional heating elements.
• Microwave with grill and convection: These combination models are true all-rounders. The convection function distributes heat evenly throughout the cavity, enabling you to bake cakes or prepare a crispy chicken. In many cases, it can replace a conventional oven.

Frequently Asked Questions

1. How many watts should a microwave have? For most everyday tasks like reheating leftovers, defrosting frozen food, or cooking vegetables, 700 to 800 watts of power is perfectly adequate. While higher-wattage appliances can potentially heat food faster, the difference is often marginal in daily use. Higher power is most useful in combination models with a grill or convection function to achieve good baking and browning results.

2. What is the advantage of a microwave without a turntable? A microwave without a turntable (also known as a flatbed microwave) uses special technology to distribute the microwaves evenly throughout the cavity. The biggest advantage is the gain in usable space. Since nothing rotates, you can also fit large, square casserole dishes or multiple small containers inside at the same time. Furthermore, cleaning the smooth ceramic base is much easier than cleaning a turntable and its roller ring.

3. What is the most effective way to clean a microwave? For a simple clean, place a microwave-safe bowl of water with a few lemon slices inside the appliance. Heat it on the highest setting for about five minutes. The resulting steam will loosen grease and dried-on food residue. Afterwards, you can simply wipe the interior with a soft cloth. Some models, like the Siemens FF020LMB2, offer special cleaning programmes (e.g., humidClean) that simplify this process even further.
