Types Of Wall Ovens

Combo microwave/ wall oven

The built-in oven with a microwave is an interesting and modern design to have in your home if your daily cooking needs are high. Especially in the current “Covid era”, cooking at home is an essential need for everyone.

This type of built-in microwave oven is very convenient because it can provide many functions at the same time. You can cook many dishes in a period of time, both quickly and easily. Therefore, this type of oven is especially suitable for chefs from amateur to professional.

Single wall oven

Single ovens are very suitable for families with people, single people because it takes up quite a modest space in the kitchen and has a thinner cross-section than other types of ovens. If you want to design a wall oven that plays a decorative role in your home, this is also the type of oven that is very suitable for you.

Double-wall oven

Using only one power source, you can operate up to 2 wall ovens, very convenient, right? This type of double oven is perfect for small and medium restaurants, or serving meals for a large family.

It takes up a bit more space than a single oven and may be more difficult to install, but it’s well worth the investment for these needs.

Triple-wall oven

This combo operates with an extremely smart system: while taking advantage of the features of a microwave oven, a convection oven can also keep food warm. The design of a triple wall oven usually combines 3 types of ovens: Convection ovens, warming compartments, and microwave ovens.

Large restaurants very often choose this special built-in oven combo. Or, if you’re a professional chef looking to practice with your creations or sell takeaways, you can also consider installing this type of oven.

How To Install A Wall Oven In a Base Cabinet

Now it’s time for you to follow these steps sequentially to start “building” your own built-in oven:

Step 1: Turn off the circuit breaker

Turn off the circuit breaker to make sure that you will not receive an electric shock or risk of fire during the operation. The circuit breaker also needs to be properly enclosed to avoid contact.

Step 2: Remove the old oven door (if any)

Unscrew the screws of the old oven door and lift it aside. Some convection ovens have very large doors, so be sure to do this step carefully.

Step 3: Turn off all power

Please find the box connection to power the storage furnace and disconnect the power. Be careful not to use it with bare hands. Remember the steps to disconnect the power so you can reset the circuit later.

Step 4: Measure inside the cabinet

This step helps you estimate whether the size of the wall oven will match the size of the wall drawer. In case you want to change to a larger oven, you will definitely have to hire a builder to repair the cabinet.

Cautions When Installing A Wall Oven In A Base Cabinet

There are two things you need to pay special attention to before installing this lavish wall oven:

  • Ensure electrical safety. Always turn off the circuit breaker and do not connect it directly when not sure about the safety. To be sure, you can use an electric tester to test it first.
  • Pay attention to the gas stove for leaks and odors.

You need to design the power outlet and the power path so that it is convenient for unplugging. Some families now often keep the oven plugs fixed because the oven is placed in the cabinet and only the front of the oven is left open, so it is quite inconvenient for the wiring and plugs. However, this is not good for your device.

When the machine is still plugged in, the machine is only in sleep mode and still consumes a certain amount of heavy electricity, especially for families that rarely use it, it is a big waste.

Therefore, when designing a kitchen cabinet to place a harmful oven, you need to have a reasonable power cord and plug convenient for you to disconnect the device when you have finished using it completely.


How to modify a wall oven cabinet?

Our first piece of advice for you is to call a team of skilled repairmen to come and modify your in-wall oven. However, if you are confident in your ability, and you have tools such as saws and professional repair tools in your home, you can completely modify it yourself.

People after a period of use will often want to expand around the wall oven to build more cabinets or redesign the surrounding kitchen shelves. We found a pretty good blog on the subject. You can refer to modify the wall oven by yourself:

How to build support for wall oven

How to install a wall oven under a cooktop?

Single wall ovens can be installed under the hob, under the counter, or integrated into a set of cabinets. For added convenience, consider combining microwave and a built-in oven. You can buy a stovetop with counters and wall ovens with cabinets to make it easier to install a wall oven underneath the cooktop.

Wall oven manufacturers recommend placing the oven 32 inches above the floor to make it easier to get food in and out. Wall ovens are quite heavy and need to be installed in a sturdy cabinet. If you place the oven in a low position, make sure the base underneath the oven is strong enough to support the weight of the oven.

To prevent fire hazards, strict installation specifications must be followed. Example: Cabinets must be at least 18 inches above the tabletop. The hob must be at least 6 inches from the wall and at least 1.5 inches from the wall and 2 inches from the front of the cooktop.

Does a wall oven need ventilation?

Wall ovens do not need ventilation like other ovens. When building the furnace, people will build vents under the door to dissipate heat for electronic devices.

  • What is your budget?
