NIGP 03192: Unit Heaters, Gas-Fired (Duct and Suspended Types)

NIGP 03192 Unit Heaters, Gas-Fired (Duct And Suspended Types) is an Item code covering gas-fired unit heater procurement and installation by state and local governments. Recent solicitations show this code activity spans water and wastewater infrastructure projects, facility maintenance operations, and public safety infrastructure upgrades. The Great Lakes Water Authority's 2027 Job Order Contract (REQ0009487), posted July 17, 2026, with response due August 27, 2026, requires contractors to manage three or more concurrent water and wastewater projects across Wayne County, Michigan, with demonstrated five-year experience coordinating electrical, controls, mechanical, HVAC, and site/civil trades—indicating that unit heater specification and installation feature within broader mechanical systems integration on large public utility and infrastructure contracts. Issuing bodies under this code include regional water authorities, county departments managing public facilities, and other special-purpose districts. The scope extends to HVAC system maintenance and upgrade work where unit heaters are component elements of larger facility conditioning systems serving training campuses, administrative buildings, and operational centers.

Geographic activity centers on Michigan and the Upper Midwest through the Great Lakes Water Authority's ongoing capital and maintenance contracting, with secondary activity in other regions where county and municipal facilities management drives equipment replacement cycles. Montgomery County's February 2026 HVAC duct cleaning solicitation (6597), due March 25, 2026, illustrates the facility operations context in which unit heater systems operate, though that particular RFQ targeted duct cleaning rather than heater procurement directly. The present market shows episodic rather than continuous solicitation activity under this code; unit heater specification typically emerges as a line item within broader mechanical or HVAC scope RFPs and job order contracts rather than as standalone equipment procurements, limiting visibility of dedicated unit heater opportunities in recent state and local notice boards.
