Competitors readily acknowledge that Johnston Boiler Company, founded in 1864, is the industry leader in the large packaged firetube boiler market. Johnston enjoys the enviable position of supplying high pressure boilers known for their efficiency and durability. Solving engineering challenges has been the company’s specialty, earning it a well-deserved reputation for quality, dependability and efficiency. Johnston Boiler manufactures water-back firetube boilers from 75 to 3,000 HP (2,500 to 105,000 pounds per hour of steam). Johnston is the only boiler manufacturer with a 15-year warranty.

In 1987, Hines Corporation purchased Johnston Boiler and provided the financial stability to allow innovation in burner design and expansion into new markets. Johnston Boiler’s proprietary burner design allows an exclusive edge as the only manufacturer of single source, very large packaged firetube boilers.
