Choosing an oven for your kitchen is not simply a matter of picking the model with the most features. The right oven should suit the way you cook, the amount of food you normally prepare, the space available in your kitchen and your budget.
There are also several different types of ovens to consider, including conventional ovens, fan-assisted ovens, built-in ovens, freestanding cookers and combination models. Features such as self-cleaning, multiple cooking functions, temperature control and energy efficiency can also affect both the purchase price and your experience over many years.
For South African households, it is worth considering electricity consumption as well as the initial purchase price. An oven can be a significant electrical appliance, particularly if it is used frequently.
This guide explains what to look for before buying an oven and how to choose a model that makes sense for your kitchen.
1. Start by Considering How You Cook
Before comparing oven brands and specifications, think about how you actually use an oven.
Someone who mainly heats frozen foods and occasionally cooks a roast has very different requirements from someone who regularly bakes bread, cakes, pizzas and large family meals.
Ask yourself:
- How often do you use your oven?
- How many people do you normally cook for?
- Do you bake regularly?
- Do you cook large roasts or casseroles?
- Do you prepare several dishes at once?
- Do you need a grill?
- Do you cook pizzas frequently?
- Do you prefer simple controls or advanced cooking programmes?
- Is energy consumption an important consideration?
There is little value in paying substantially more for specialised functions that you are unlikely to use.
At the same time, buying an oven that is too basic for your cooking habits can become frustrating.
2. Decide Between a Freestanding Cooker and Built-In Oven
One of the first decisions is whether you want a conventional freestanding cooker with an oven underneath the hob or a separate built-in oven.
Freestanding cookers
A freestanding cooker combines the oven and cooking surface in one appliance.
Advantages include:
- Usually simpler to install
- Provides both an oven and hob in one appliance
- Often available at relatively accessible prices
- Suitable for kitchens where space is limited
- Easy to replace without redesigning the entire kitchen
For many households, a freestanding cooker remains a practical option.
Built-in ovens
A built-in oven is installed into the kitchen cabinetry, usually either underneath the countertop or at a more convenient raised height.
Advantages include:
- A cleaner, integrated appearance
- More flexibility when designing the kitchen
- Easier access if installed at waist or chest height
- Can be combined with a separate hob
- Allows greater flexibility in appliance placement
However, installation needs to be planned carefully. Cabinet dimensions, electrical requirements and ventilation must all be considered.
See How to Choose the Right Dishwasher for Your Kitchen for another guide to planning and selecting built-in kitchen appliances.
3. Choose the Right Oven Size
Oven capacity is usually measured in litres, but the external dimensions are equally important.
A larger oven isn’t automatically better.
A very large oven may consume more energy when heated, while a smaller oven may not provide enough usable cooking space for a family.
Think about the largest meals you normally prepare.
For example, if you regularly cook:
- Large family roasts
- Multiple trays of food
- Several loaves of bread
- Large baking dishes
- Multiple pizzas
- Large casseroles
you may benefit from a larger-capacity oven.
If you mainly cook for one or two people, a smaller oven may be sufficient.
Measure the available space
Before ordering a built-in oven, measure the opening in the cabinetry carefully.
Check:
- Width
- Height
- Depth
- Ventilation requirements
- Electrical connection
- Door clearance
- Space around the appliance
Do not rely solely on the advertised external dimensions. Installation specifications can vary between models.
If you are replacing an existing built-in oven, recording the dimensions of the current installation space can make finding a suitable replacement much easier.
4. Understand Conventional and Fan-Assisted Ovens
One of the most useful distinctions between ovens is how they distribute heat.
Conventional oven
A conventional oven generally uses heating elements to heat the oven cavity, with heat naturally circulating inside.
This can work very well for many traditional cooking tasks.
Fan-assisted oven
A fan-assisted or convection oven circulates hot air around the oven cavity.
This can provide more even heat distribution and may allow you to cook on more than one shelf.
For people who bake frequently or regularly prepare several dishes, fan-assisted cooking can be particularly useful.
However, recipes written for conventional ovens may require adjustments to temperature or cooking time when using a fan-assisted setting.
5. Look at the Cooking Functions
Modern ovens can offer a surprisingly large number of cooking programmes.
Some common functions include:
Conventional baking
Uses the standard heating elements and is suitable for many everyday dishes.
Fan cooking
Circulates hot air to distribute heat more evenly.
Grill
Uses a heating element to brown or cook food from above.
Useful for:
- Toasting
- Browning cheese
- Grilling meat
- Finishing dishes
Fan and grill
Combines the grill with air circulation and can be useful for cooking or browning larger pieces of food.
Bottom heat
Provides heat primarily from underneath and can be useful for certain baking applications.
Defrost
Some ovens offer a low-temperature setting designed to help defrost food.
Pizza setting
Some models have a dedicated pizza programme that combines heating elements and fan operation to create conditions suited to pizza.
The important point is not to count the number of programmes.
Instead, identify the functions you will genuinely use.
An oven with 15 cooking programmes isn’t necessarily more useful to you than one with six well-designed functions.
6. Check the Temperature Range and Control
Accurate temperature control is particularly important if you bake.
Look for an oven with:
- A clearly adjustable temperature range
- Easy-to-read controls
- Consistent temperature regulation
- A useful thermostat
- A clear display where appropriate
Some ovens use traditional rotary controls, while others have digital touch controls.
Neither approach is automatically better.
Consider which type of control you find easiest to use, particularly if several members of the household will operate the oven.
7. Consider Fan-Assisted Cooking if You Bake Regularly
If baking is an important part of your cooking, the way an oven distributes heat deserves particular attention.
Uneven heating can result in:
- Cakes browning unevenly
- One side of a tray cooking faster than the other
- Biscuits cooking differently depending on their position
- Bread developing inconsistent crusts
A good fan-assisted oven can help distribute heat throughout the cavity.
However, the actual performance of different ovens can vary. Reading specifications is useful, but customer reviews can also provide insight into real-world cooking performance.
8. Look at the Shelves and Interior Layout
The internal layout of an oven is easy to overlook when shopping.
Check how many shelf positions are available and whether the shelves can be moved easily.
Useful features can include:
- Multiple shelf levels
- Telescopic runners
- Sturdy oven racks
- Easy-to-remove shelves
- Full-width baking trays
- Adequate space between shelves
Telescopic runners can be particularly convenient because they allow a tray or rack to slide out more easily.
This can make it easier to check food without reaching deep into a hot oven.
9. Think About Oven Cleaning
Cleaning an oven is one of the less enjoyable parts of cooking.
Different ovens use different approaches to make cleaning easier.
Easy-clean interiors
Some ovens have specially designed surfaces that are easier to wipe clean.
Steam cleaning
Some models use steam or moisture to loosen food residue.
Catalytic cleaning
Certain ovens use special internal surfaces designed to break down grease at high temperatures.
Pyrolytic cleaning
Higher-end ovens may offer a pyrolytic cleaning cycle that uses very high temperatures to turn food residue into ash that can then be wiped away.
These systems can be convenient, but they may add to the purchase price.
If you rarely use your oven, paying considerably more for advanced cleaning technology may not make financial sense.
10. Check the Oven Door
The oven door is another feature worth examining.
A good oven door should open smoothly and provide a clear view of the food.
Features worth considering include:
- Double or triple glazing
- A large viewing window
- A cool-touch exterior
- A sturdy handle
- Smooth hinges
- Easy-to-clean glass
Multiple layers of glass can help reduce heat transfer to the outside of the door.
This can be particularly useful in households with children.
11. Consider Energy Efficiency
Electricity costs are an important consideration when buying a major appliance.
An oven can use significant amounts of electricity, particularly when used frequently and for long cooking periods.
However, energy efficiency is not determined solely by the oven’s advertised efficiency rating.
Your actual electricity consumption will also depend on:
- Cooking temperature
- Cooking time
- Frequency of use
- Oven capacity
- Preheating habits
- Whether the oven is opened repeatedly
- The type of food being cooked
Avoid opening the door unnecessarily while cooking. Every time the door is opened, heat escapes and the oven needs to replace it.
Using the appropriate cooking temperature and avoiding unnecessarily long cooking times can also help.
12. Think About Preheating
Some ovens heat to the required temperature more quickly than others.
Rapid preheating can be convenient, particularly if you cook frequently.
However, don’t assume that a “fast preheat” feature is essential.
If you normally plan your meals in advance, saving a few minutes may not justify a significant increase in purchase price.
Instead, consider how the oven performs across the features that you will use every day.
13. Check the Electrical Requirements
This is particularly important when replacing an old oven.
Don’t assume that a new oven can simply be plugged into the existing connection.
Some larger ovens have specific electrical requirements and may need professional installation.
Before purchasing, check:
- Voltage requirements
- Power rating
- Plug or hard-wiring requirements
- Circuit requirements
- Installation instructions
- Ventilation requirements
If you are uncertain, have the installation requirements checked by a suitably qualified electrician before buying the appliance.
The cost and complexity of installation should be included in your overall budget.
14. Consider a Combination Oven
Some appliances combine several cooking methods in one unit.
Depending on the model, a combination oven may include functions such as conventional oven cooking, fan cooking, grilling and microwave cooking.
These appliances can be useful when kitchen space is limited.
However, there is a trade-off.
A combination appliance may not perform every function as well as a dedicated appliance.
If you regularly use a microwave and conventional oven, a combination model may make sense. If baking is your main priority, however, a dedicated oven may be more appropriate.
15. Don’t Ignore the Oven’s Exterior Dimensions
Oven capacity and external size are not the same thing.
A model may have a relatively large internal cavity but require considerable cabinet space.
Before buying, check the manufacturer’s installation diagram rather than relying only on the product photograph or basic dimensions displayed by a retailer.
Also check whether the oven door requires additional clearance when fully opened.
This is particularly important in smaller kitchens.
16. Look at the Accessories Included
Two ovens at similar prices may come with quite different accessories.
Check whether the oven includes:
- Baking trays
- Grill racks
- Roasting trays
- Telescopic runners
- Pizza trays
- Additional shelves
- Temperature probes
Accessories that you would otherwise have to purchase separately can affect the real value of an oven.
However, don’t allow a long list of accessories to distract you from the basic performance and suitability of the appliance.
17. Consider the Brand and After-Sales Support
An oven is normally a long-term purchase, so the company behind the appliance matters.
Before buying, check:
- Warranty period
- Availability of replacement parts
- Service network
- Local technical support
- Availability of accessories
- Cost of common replacement components
This is especially relevant in South Africa, where obtaining parts or servicing less-established brands can sometimes be more difficult.
A slightly cheaper appliance may not represent good value if servicing becomes difficult later.
18. Read Reviews Carefully
Online reviews can be useful, but they need to be interpreted carefully.
Look for repeated comments rather than relying on a single very positive or negative review.
Pay particular attention to comments about:
- Temperature accuracy
- Heating consistency
- Fan noise
- Door quality
- Ease of cleaning
- Control reliability
- Installation
- Long-term reliability
A review saying that an oven “looks beautiful” is much less useful than several customers commenting on how evenly it cooks.
19. Decide Which Features You Actually Need
It is easy to become distracted by features when comparing modern ovens.
Make three lists before shopping:
Essential
Features you definitely need.
For example:
- Suitable capacity
- Fan-assisted cooking
- Grill
- Accurate temperature control
Useful
Features that would be convenient but aren’t essential.
For example:
- Telescopic runners
- Self-cleaning function
- Digital timer
- Rapid preheating
Unnecessary
Features you are unlikely to use.
This approach can help prevent you from spending extra money simply because a more expensive model has a longer specification list.
20. Set a Realistic Total Budget
The purchase price isn’t the only cost involved.
Your total budget may include:
- Oven
- Delivery
- Installation
- Electrical work
- Cabinet modifications
- Accessories
- Future servicing
- Electricity consumption
This is particularly important for built-in ovens.
A model that appears affordable initially may become considerably more expensive if the kitchen needs modification before installation.
21. Oven vs Air Fryer: Do You Need Both?
Many South African households now use air fryers alongside conventional ovens.
An air fryer can be convenient for smaller quantities and relatively quick meals, while an oven remains more practical for larger dishes and family-sized cooking.
If you already own an air fryer, consider how you use it before deciding what your new oven needs to do.
For a separate guide to choosing an air fryer, see How to Choose the Right Air Fryer for Your Home.
The two appliances can complement each other rather than necessarily replacing one another.
22. Oven Buying Checklist
Before purchasing, work through this checklist:
Size
- Will it fit the available space?
- Is the internal capacity sufficient?
- Can the door open fully?
Cooking
- Does it have the cooking functions you need?
- Is fan-assisted cooking available?
- Does it include a grill?
Controls
- Are the controls easy to understand?
- Is the temperature range suitable?
- Is there a useful timer?
Cleaning
- Is the interior easy to clean?
- Would a specialised cleaning system be worthwhile?
Energy
- What is the power rating?
- How frequently will you use the oven?
- Are there useful energy-saving features?
Installation
- What electrical connection is required?
- Will the existing kitchen accommodate it?
- Will professional installation be necessary?
Long-term ownership
- What is the warranty?
- Are replacement parts available locally?
- Is there a local service network?
Final Thoughts
The best oven for your kitchen is not necessarily the most expensive model or the one with the longest list of features.
Start by considering how you actually cook, then choose an appropriate size and type. From there, compare useful features such as fan-assisted cooking, temperature control, shelf configuration, cleaning systems and energy consumption.
For many households, a reliable oven with good temperature control, useful cooking functions and straightforward operation will provide more value than an expensive model filled with features that rarely get used.
Take measurements before shopping, check installation requirements carefully and compare the total cost of ownership rather than simply looking at the advertised purchase price.
Most importantly, choose an oven that matches your cooking habits. A well-chosen appliance should make everyday cooking easier without paying for capabilities you don’t need.
