What Smith Cast Iron Boilers does
Smith Cast Iron Boilers is a Westfield, Massachusetts-based manufacturer of cast iron hydronic heating boilers serving residential, light commercial, and large institutional customers across North America. Founded in 1853 by brothers Henry and Edwin Smith as the HB Smith Company, the firm holds the distinction of creating the first sectional cast iron boiler — a design that allowed individual sections to be isolated and repaired without disabling the entire system. Today's product portfolio centers on three active commercial series — the 19HE (308-1,750 MBH), 28HE Steam (931-4,622 MBH), and 28HE RTS Water (931-4,622 MBH) — built around rugged cast iron heat exchangers with forced-draft firing. Residential offerings (GVX, GBX, GSX, GC160, 8HE) have been discontinued, narrowing the company's strategic focus toward commercial and institutional applications including schools, universities, hospitals, and government buildings, particularly in the Northeast and Midwest United States.
The business operates an indirect go-to-market model, selling exclusively through a territory-based network of independent sales representatives and a digital Smith Specifier configuration tool used by contractors and engineers to size, configure, and generate specifications. Pricing is quote-based and not publicly disclosed. The commercial product line supports integration with major building automation systems via BACnet IP/MSTP, LonWorks, and Johnson Controls Metasys N2 protocols, and the company holds Buy American Act compliance certification. Smith Cast Iron Boilers operates as a subsidiary of Mestek, a diversified HVAC manufacturing conglomerate, with corporate documentation, software, and legal infrastructure hosted under the mestek.com domain. Headcount is in the 11-50 range, consistent with a focused specialty manufacturer rather than a scaled industrial player.
