Convection microwave oven or an OTG: What to buy for your kitchen?

  • Highlights

  • An OTG is a combination of an oven, toaster, and grill

  • A convection microwave cooks food using micro-waves

  • OTG ovens cook food with heated coils

  • Microwaves are costlier and more energy efficient than OTG

What is an OTG?

An OTG or an oven, toaster, grill is essentially a smaller version of a traditional oven. It uses heated coils to cook meals and requires much less setting up.

What is a convection microwave?

A convection microwave is more sophisticated than a normal microwave and has many additional features apart from reheating and boiling. As its name suggests, it uses microwaves to cook your meals.

Factors to consider before purchase

Here are the factors that you need to consider before purchasing either:

The science behind cooking

When cooking with an OTG, the heat is radiated by the coils and absorbed by the food. There is a fan present to distribute the heat, but most of the heat is dispensed directly below the coils. On the other hand, convection microwaves heat the water molecules present in food, thereby cooking it. A rotating plate and the microwaves ensure that the food is cooked evenly.

What to cook

An OTG is best used for baking, toasting and grilling. You can bake cakes, grill meat and toast bread with ease. A convection microwave can perform all of these functions, along with being able to reheat, cook and de-freeze, which the OTG cannot.


An OTG’s capacity may reach up to 60 litres, whereas convection microwaves reach a capacity of just 32 litres. So, for large batches of food, an OTG might be the better option. Additionally, the rotating surface in a microwave is quite small, which makes putting large dishes in it a problem. Moreover, though OTGs have larger capacities, they are much easier to handle owing to their light weight.


The temperature range of both a convection oven and an OTG are almost the same, but the preheat time varies. Where an OTG can take up to 15-20 minutes to preheat, the convection oven only takes around 5 minutes. This can considerably decrease the cooking time.

What is 100% finance?

Ease of use

Convection microwaves have a digital display, that allows an easier track of the temperature and time as compared to the knobs on an OTG.

The upfront cost of buying an OTG is around Rs.10,000 for 42 litres, whereas a convection microwave costs around Rs.16,000 for 30 litres. Although the upfront cost of an OTG is lesser, the energy efficiency of a microwave oven is greater. The microwave oven uses 20% less energy than an OTG, saving money in the long run.
