What type of ovens are typically stacked to save space?

Deck ovens are typically stacked to save space, making them an efficient choice for commercial kitchens where maximizing floor area is essential. These ovens feature a design that allows for multiple chambers or "decks" to be placed one above the other. This stacking capability not only utilizes vertical space but also allows for greater production capacity, as multiple items can be baked simultaneously at different temperatures or with different settings.

In contrast, convection ovens circulate hot air to cook food uniformly but may not be designed to be stacked in the same way. Microwave ovens, while compact and space-saving, do not lend themselves to conventional stacking for cooking purposes. Conventional ovens generally have a standard size and design that may not allow for stacking either and are typically standalone units. Therefore, deck ovens are the most practical and space-efficient choice when considering options that can be stacked in a commercial kitchen setting.
