What Superior Boiler does

Superior Boiler is a custom-engineered commercial and industrial boiler manufacturer headquartered in Hutchinson, Kansas. Founded in 1917 as Superior Welding Shop, the company designs and builds firetube boilers (Scotch Marine Apache, Aztec, Dakota, Mohawk, Mohican, Seminole, Ohio Special), watertube boilers (Appalachia, Denali, Iroquois, Lakota, Ottawa, Shawnee, Tomahawk, Saponi), condensing boilers (Cheyenne), vertical firetubes (Triad Series, Ute), firebox boilers (Arrowhead, Osage), waste heat recovery units, heat recovery steam generators (Huron), boiler skid packages, and supporting boiler room equipment. The company holds multiple granted U.S. patents on watertube designs (including the patented DFW O-type platform granted June 2022) and emphasizes thicker-than-ASME steel construction, non-proprietary parts, and broad fuel capability including hydrogen-ready burners. Manufacturing is concentrated in three Hutchinson facilities totaling 317,000 sq. ft., and the company maintains ISO 9001:2015 certification re-certified in October 2023.

The business model is quote-based, sales-led, and project-driven. Superior Boiler sells primarily through an internal sales force and an authorized network of regional sales representatives across the United States, with a dedicated regional office in Houston, Texas for Gulf Coast coverage and an exclusive distribution partnership with Nationwide Boiler Inc. for the DFW product line. Customers span commercial buildings, industrial manufacturing, healthcare, education, government, and equipment-rental end-markets, with named case-study deployments at Stennis Space Center, Scripps Mercy Hospital, Mayo Clinic Health System, Alderson-Broaddus College, and the Beef Processing Facility, among others. Revenue is generated from custom-built hardware sales plus an aftermarket parts and services stream that covers both Superior and competitive equipment.

Following the November 2025 acquisition by Watts Water Technologies (NYSE: WTS) as part of a $257.1M three-deal Q4 2025 transaction, Superior Boiler operates as a wholly-owned subsidiary of the publicly traded strategic acquirer. At acquisition, annualized sales were approximately $60 million, and the deal is positioned to enable cross-selling of Superior's custom boiler capabilities into Watts' plumbing and water-quality distribution channels.
