My husband and I recently moved into a new condominium, with a lovely new kitchen, with all new appliances. I'm very happy with the Wolf range, but am less than happy with the Wolf double ovens. It typically takes between 40 and 45 minutes for the oven to preheat to 425, which seems like an absurdly long period of time. In fact, with certain recipes, it takes longer to preheat the oven than to cook the food. Any thoughts or experience with these ovens?
