Combi Oven vs Convection Oven: Which Should You Buy?

Choosing between a combi oven and a convection oven is one of the most important equipment decisions for a professional or serious home kitchen. Here is a comprehensive breakdown of how the two compare.

What Is a Combi Oven?

A combi oven (combination steam oven) combines three cooking modes in a single unit: convection (dry hot air), steam (100% humidity), and combination (hot air + steam simultaneously). This versatility allows a single machine to replace a steamer, convection oven, and braising pan.

What Is a Convection Oven?

A convection oven uses a fan to circulate hot dry air, cooking food faster and more evenly than a conventional oven. Convection ovens are available in both commercial and home models and excel at baking, roasting, and browning.
