Weil-McLain began in Chicago in the year 1881. Founded by Isadora and Benjamin Weil, the company operated under the name Weil Brothers until 1918 with the acquisition of the J.H. McLain Company. The newly minted Weil-McLain moved boiler plant operations to their current headquarters in Michigan City, Indiana. The Weil-McLain company then went on to grow into a U.S. leader in the manufacture of cast iron boilers.
Never a company to rest on their laurels, Weil-McLain spent the end of the 20th and the first part of the 21st Century in expanding their product line and corporate reach. With the purchase of the Williamson Thermoflo, Weil-McLain expanded into the oil furnace market. This expansion caused the company to outgrow their initial Michigan City facilities. On the strength of Weil-McLain boilers, the company opened a training and manufacturing facility in Eden, North Carolina. Further expansion overseas occurred in 2006 when Weil-McLain purchased the Taishan Maeda Boiler Co. in Tai’an, China. From this base, Weil-McLain can provide Weil-McLain oil fired boilers and boiler parts to the Chinese market. As they stand today, Weil-McLain employs over 700 international employees.
Weil-McLain oil boilers work much the same as a standard hydronic boiler, except in its use of heating oil rather than natural gas for the fire. Competitive Weil-McLain pricing structures across their whole line of oil-fired boilers have helped the company maintain its status as an industry leader. In addition to their array of oil-fired boilers, Weil-McLain also offers furnaces, air conditioners, water heaters and a variety of temperature regulation devices for their HVAC products.
