Is it temperature controlled?
Most heated shelves are temperature controlled. Units should feature a control dial, offering complete control over the shelf’s surface. Some of the shelves can get as hot as 220 degrees Fahrenheit.
Can it be used as a cold shelf if not plugged in?
Unless otherwise stated, heated shelves cannot be used as a cold shelf. The temperature controls will only hold the temperatures mentioned in the specification sheet. They can’t be set below the given range.
Can you cook things on it like a flat top griddle?
No. Heated shelves are designed as merchandising equipment to keep cooked food at optimal serving temperatures. Although it has a dial to keep the temperature controlled, it should not be used as a cooking tool. These units have a heating system meant to distribute heat evenly to keep foods fresh and ready to serve for extended periods of time.
