How to cut the cost
- Use it instead of the full oven for 1-4 servings; it uses roughly a third to half the energy.
- Use the convection setting and reduce temperature by 25°F.
- Keep the crumb tray clean so heat reflects back to the food.
- Don't preheat for toasting or reheating.
Cheaper ways to get the job done
Convection airflow cooks faster at lower temperatures, trimming run time.
