Buying a Combination Microwave: How to Avoid Common Mistakes

A combination microwave seems like the ideal all-in-one solution, especially if your kitchen space is limited. It can heat, bake, grill, and sometimes even air fry, all in a single appliance. However, in practice, many models fail to live up to their marketing promises. Before you buy a combination microwave, it's crucial to know the pitfalls to avoid making a purchase you'll regret.

As a Joybuy Product Recommendation Officer, I'll help you cut through the noise of specifications and features. We'll focus on what truly matters for daily use in UK households.

The 3 pitfalls of choosing a combination microwave:

  1. The "Oven Function" That Isn't an Oven: Many cheaper models advertise an oven function but only have top and bottom heating elements or just a grill. To bake a cake, bread, or a crispy pizza, you need a combination microwave with convection (hot air). Without that fan, heat isn't distributed evenly, leading to undercooked or burnt results.
  2. Unrealistic Capacity: A 30-litre capacity sounds spacious, but due to a large, non-deactivatable turntable, a standard rectangular oven dish often won't fit. The stated litre capacity, therefore, says little about the actual usable space.
  3. Overhyped "Healthy" Features: A combination microwave with an air fryer function sounds like a great two-in-one deal. However, this is often nothing more than the standard convection function combined with a perforated baking tray. While the result can be good, it's not always comparable to a dedicated air fryer.

What to Look For: The Specifications That Really Matter

To make the right choice, it's important to understand a few technical specifications. These determine whether the appliance is suitable for your cooking needs.

Functions: More Than Just Reheating

A true combination microwave combines multiple appliances. Pay attention to the presence and power of the following functions:

  • Microwave Power: For reheating and defrosting, a power rating of 900 to 1000 watts is a good standard.
  • Convection (Hot Air): This is the most important feature for a fully-fledged microwave with a true oven function. A fan circulates the hot air evenly. A convection power of 1500 to 2500 watts is common for good baking and roasting results.
  • Grill: A combination microwave with a grill is ideal for creating a crispy top on a casserole or browning cheese. A grill power of 1000 to 1500 watts is sufficient for most tasks.

Capacity and Dimensions: Will That Casserole Dish Actually Fit?

Capacity is expressed in litres. For a one or two-person household, 20-28 litres is sufficient. Families should look for models of 30 litres or more.

More important than the number of litres is the usable internal space. A freestanding combination microwave with a deactivatable turntable offers significantly more flexibility. This allows you to use the entire base for large, square oven dishes. Some models have no turntable at all (a 'flatbed' design), which maximises the usable space.

New Technologies: What Do 'AirFry' or 'Crisp' Really Mean?

Brands are constantly introducing new technologies. A Samsung combination microwave with 'Slim Fry' technology, for example, combines the grill with hot air circulation for a fried effect with less oil. According to Samsung, the included 'Crusty Plate' ensures an extra crispy base. These are useful additions, but it's good to know that they build on the basic principles of grilling and convection.

## Frequently Asked Questions about Combination Microwaves

What's the difference between a combination microwave with convection and one with just an "oven function"? An "oven function" can be misleading. Sometimes it just means there's a grill element or top and bottom heating. A combination microwave with convection has a fan that circulates hot air evenly throughout the cavity. This is essential for baking cakes, bread, and evenly cooking larger dishes.

How many watts does a good combination microwave need? This depends on the function. For the microwave function, 900-1000W is a good guideline. For the convection function (oven), you ideally want 1500W or more for good baking results. A powerful grill (1200W+) will ensure a nice brown and crispy finish.

Can a combination microwave completely replace a conventional oven? For many households, especially those in smaller kitchens, a combination microwave can certainly replace a full-sized oven. A good model can bake, roast, and grill. However, keep in mind that the internal space is smaller than that of a traditional built-in oven. For large families or avid bakers who want to cook multiple dishes at once, a combination microwave might be more of a handy supplement than a complete replacement.
