UNSPSC 40101849: Hot water distribution header

A type of device that gathers the valves in one place to distribute the hot water generated from the hot water heater, such as boiler and others, to several zones like cabinet panel or distributing board.

UNSPSC 40101849 Hot water distribution header is a Commodity code that captures state and local procurement of hot water system components, including water heaters, expansion tanks, heat exchangers, distribution piping assemblies, and related thermal distribution equipment serving residential and municipal facilities. Recent solicitations show governments buying both complete water heater units with ancillary compliance components and standalone system infrastructure to replace aging heating and hot water systems in housing, correctional facilities, and municipal buildings. Issuing bodies include city community development departments managing housing rehabilitation programs, state correctional and veterans facilities, municipal utility authorities, county property management operations, and local housing authorities. Water heater replacement and hot water system upgrades appear across diverse issuing-body types and geography, with procurement driven by aging infrastructure, code compliance requirements, and energy efficiency mandates rather than concentrated in any single jurisdiction type.

The code sees recent activity across California, Michigan, Connecticut, Georgia, Pennsylvania, Illinois, and Minnesota, with no dominant state concentration. Representative recent solicitations include the Housing Authority of the City of Alameda (RFP 2026RFPAHAHD001, April 2026) seeking furnace and water heater replacement with code-compliance upgrades in 17 residential units in Alameda County, requiring new 40-gallon water heaters with expansion tanks and seismic straps to meet SCAQMD Rule 1121; the City of Jackson Community Development Department (IFB 2026COMMUNITYDEVELOPMENT028, July 2026) procuring water heater and furnace replacement at 237 N Gorham Street, Jackson, Michigan, with sealed-bid submission by July 7, 2026; the State of Illinois Department of Corrections at Sheridan Correctional Center (BOA 26426DOCSHERIB52254, May 2026) issuing a small-purchase order for HVAC system components including air conditioning units, furnaces, evaporator coils, and related accessories with delivery by June 15, 2026; and the Veterans Home of California—Redding (RFP 25RS0032, April 2026) seeking design, engineering, and installation of domestic hot water system upgrades. CDBG-funded housing rehabilitation, prevailing wage compliance, and code-compliance requirements appear consistently across solicitations. Performance bonds, liability insurance, state licensing, and multi-year warranty provisions are standard contract terms.
