No, it is not safe to place one oven directly on top of another oven. Placing an oven on top of another oven can create a fire hazard and pose serious safety risks. Ovens generate heat during operation, and stacking them can lead to excessive heat buildup, potentially causing damage to the ovens and surrounding cabinetry or countertops.
If you require additional cooking space or a stacked oven configuration, it is recommended to consult with a professional appliance installer or kitchen designer who can evaluate the space and provide appropriate solutions. They can help ensure that the installation meets safety standards and that the necessary structural modifications are made to accommodate the stacked ovens safely.
