Two brands of American-made water heaters, Bradford White and Niagara, are available for purchase on Amazon.com, as of 2015. Amazon offers a 40-gallon and 50-gallon Bradford White natural gas water heater and multiple Titan digital tankless water heaters manufactured by Niagara.
Bradford White manufactures its water heaters in a rapidly expanding plant in Middleville, Michigan. The company has a new training facility, as well as a 100,000 square foot expansion for increased manufacturing and shipping capabilities. The company also has other manufacturing plants in Rochester, New Hampshire and Niles, Michigan through the acquisition of Laars Heating Systems and Niles Steel Tank. The company headquarters is currently located in Ambler, Pennsylvania.
Niagara Industries began in 1985 in Miami, Florida with the creation of the first electronic tankless water heater for the whole house. Niagara received help from engineers at Florida's International University and other electronics companies to create the new product. After it was given a patent for the tankless water heater in 1995, Niagara moved to a larger location in Miami. At the new location, the company started a research and development section to create new products and improve on old ones. Niagara has 10 different products, as well as a custom line to meet any customer's need.
