Stainless steel tea kettles can be used to make tea, coffee, and other beverages in the commercial kitchen. You should look for a kettle with the ability to hold at least 2 quarts, made with durable stainless steel. The tea kettle should heat quickly and have a wide enough spout to make it easy to pour the water. The stainless steel handle should be covered with heat-resistant material or at least tell you to use a potholder or oven mitt when you use it. The opening should be wide enough to fill it with water and the lid easy to remove. A wider spout is easier to pour than very narrow spouts.
