Food warmers are available through online retailers Amazon.com, Ebay and WebstaurantStore, as of 2015. National retailers, such as Walmart and Target, also sell food warmers online. Home, catering and commercial food warmers are available.
Amazon.com carries commercial and consumer food warmers. Consumers can choose between small infrared heat lamps with one to three bulbs, chafing dishes and fried food countertop warmers. Commercial food warmers include food wells with and without drains, food warming cabinets and warming drawers. The retailer also carries buffet warmers with multiple pans. Auction site Ebay also carries commercial and consumer food items; however, its inventory changes daily. The site has sections dedicated to buffet, catering and commercial food warmers.
WebstaurantStore carries commercial countertop food warmers with either infinite or thermostatic controls and adjustable heat settings. It offers pass-through, insulated and movable heating cabinets and correctional holding cabinets as large as 50 cubic feet. The store has both electric and gas steam tables, and it has industrial-size fried food warmers.
Target and Walmart sell food warmers for home and catering. Warming trays can be used to keep a dish warm between courses, while buffet servers can keep up to three dishes warm using separate compartments. Fold-away warmers look similar to buffet servers but are disposable. Both stores sell dip warmers, and Walmart also sells chafing dishes.
