What drives the difference
- Warming drawer: Built-in warming drawers use 400-500 W heaters and cycle to hold 140-200°F; buffet servers 200-300 W.
- Electric oven: A standard 30-inch electric oven has a 2.5-3.5 kW bake element. One hour at 350°F, including about 15 minutes of preheat, uses roughly 1.5-2 kWh as the element cycles.
