Microwaves with the highest wattage are generally heavy-duty microwaves specially designed for a commercial setting that are capable of 2,200 watts of power. Other commercial microwave wattages include 1,000-, 1,200- and 1,800-watt models. Hourly outputs range from 13 on the 1,000-watt model to 28 on the 2,200-watt model.
Heavy-duty commercial microwaves are designed with durability in mind and may be used up to 200 times in a single day. Generally, they are used in the back of the house in restaurants for steaming vegetables or seafood, quickly heating entrees or defrosting foods. They may also be put into use in quick-service settings where fast turnarounds are necessary.
