The size and capacity of box ovens are crucial factors in making the right decision for your family. Picking the wrong size could lead to waste or a loss of aesthetic appeal. To assist you in selecting the most suitable oven with the right capacity and size, refer to the article below!
1. What is the size of a box oven?
A box oven is a rectangular-shaped oven, with a design and heating mechanism similar to convection ovens. The front-facing door design is convenient, and it uses an electric resistor to cook food thoroughly.
The size of the oven will be determined by length × width × height. The size mentioned here refers to the overall oven size, not just the oven cavity size. Be careful not to confuse the two!
2. Family Usage Purposes
Depending on the family's usage needs, you can choose a suitable oven. For example, if you're roasting meat, fish, or vegetables, you can go for any oven.
If you enjoy occasionally or regularly baking cakes for the family, you should opt for an oven with a capacity of 25 liters or more, stable temperature, interior light, double-layered glass door, convection baking, dual heating elements, and more.
3. What is the Capacity of a Box Oven?
The capacity of the oven here refers to the volume inside the oven cavity. If you have complete information on both the size and capacity of the box oven, you will undoubtedly choose the most suitable products for your cooking needs.
4. Frequency of Usage (Frequent or Infrequent)
When determining your family's oven usage level and the primary user (who uses it regularly? What type of dishes are often cooked? Whom do you cook for?), you'll easily receive advice on the suitable size.
For example, if you have many young children at home and want their food to always be warm or if you want to quickly cook soup, then you should choose ovens with a capacity of around 25 – 35 liters.
5. Capacity for Cooking Suitable for Different Dishes
Each type of oven will have different capacities, suitable for usage needs and the number of family members.
– Ovens with a capacity below 20 liters can roast meat, bake whole chickens under 1.5 kg.
– Ovens with a capacity from 20 – 35 liters can bake whole chickens up to 1.5 kg.
– Ovens with a capacity above 35 liters can roast whole chickens from 2 kg and above.
6. Choosing the Appropriate Power
Power and capacity are often proportional, so the larger the capacity, the higher the power, resulting in shorter cooking times.
– Ovens with a capacity below 20 liters: power is 1300 W.
– Ovens with a capacity from 20 – 35 liters: power is around 1400 W – 1600 W.
– Ovens with a capacity above 35 liters: power is around 1800 W – 2980 W.
