What Heat Fab does
HeatFab, founded in 1978 and headquartered in Turners Falls, Massachusetts, is a specialty manufacturer of residential and commercial venting systems for gas-fired heating appliances. The company's Saf-T Vent product family comprises four core platforms: the double-wall Model CI Plus/CI 316 (4"-32" ID) for condensing appliances, the concentric direct-vent Model SC Plus/SC 316 (3"/5" and 4"/7" ID/OD) for zero-clearance applications, the single-wall Model GC Plus/GC 316 (18"-32") for Category I-IV gas appliances, and the single-wall Model EZ Seal Plus/EZ 316 (3"-16") featuring factory-installed integral seals. All products are constructed from super ferritic stainless steel (UNS S44735, designated 29-4C) with grade 316L available as an alternative, engineered with overlapping joint designs to keep acidic condensate away from seals and patented Ring-and-Tab or Sure Seal locking systems that allow tool-free installation. Maximum temperature ratings reach 550°F with zero clearance to combustibles in some applications.
The business operates as a B2B, sales-led manufacturer specified by OEMs for more than 20 years, serving heating-equipment manufacturers, HVAC contractors, and distributors. Pricing is quote-based, configured by diameter, material, and quantity, and distributed through direct sales, sales representatives, a myDVG portal, and a Duravent Group-integrated brand store. HeatFab is a brand within Duravent Group, a diversified climate-technology platform unifying 14 venting and air-control brands including Selkirk, Hart & Cooley, and Security Chimneys, with which HeatFab shares sales contacts, marketing infrastructure, and distribution. Certifications (UL 1738, ULC-S636, UL 641, ULC-S609, ULC-ORD-441) and proprietary patents form the regulatory and intangible-asset backbone of the company's specification-based competitive position across commercial, institutional, and residential end markets including schools, hospitals, hotels, offices, restaurants, and multi-family housing.
