What U.S. Boiler Company does
U.S. Boiler Company, LLC is a privately held U.S. manufacturer of residential and commercial hydronic heating equipment headquartered in Lancaster, Pennsylvania, with a cast iron heat exchanger production facility in Zanesville, Ohio, and a workforce of nearly 300 people. The company was previously known as Burnham and carries that legacy brand heritage. Its product portfolio spans high-efficiency condensing gas boilers (Alta, Alpine, Aspen, Citadel), mid-efficiency cast iron gas and steam boilers (ES2, Series 2/3/X-2, Independence, SteamMax), oil-fired boilers (MPO-IQ, EMP, MegaSteam, V8H), the Ambient electric boiler and Ambient HP hydronic heat pump for electrification applications, Alliance indirect water heaters in stainless steel, thermoplastic, and stone-lined configurations, cast iron radiators, and proprietary boiler control systems (Sage2.3, IQ, IHC) plus the USB Connect Bluetooth/app accessory.
The company's technology stack centers on three heat exchanger architectures — stainless steel for condensing units, cast iron (made in Zanesville from recycled material) for legacy and oil-fired lines, and electric / air-to-water for the electrification line — wrapped by an internally developed control layer. Five models are ENERGY STAR certified (Alta, Alpine, Aspen, MPO-IQ, EMP) with documented efficiencies ranging from 82% on legacy cast iron steam units to 98% on the Citadel commercial boiler and up to 395% on the Ambient HP heat pump. The company also holds an IRS Qualified Manufacturer registration (QMID: Y6C3) that lets qualifying products access the federal Energy Efficient Home Improvement Credit through December 31, 2025.
U.S. Boiler sells exclusively through a two-tier indirect channel: professional heating contractors who design, quote, and install systems for end homeowners and commercial building operators, plus regional distributors and wholesalers who supply those contractors. The company does not sell directly to consumers. Revenue is generated from one-time hardware sales of boilers, water heaters, radiators, and control accessories, with pricing set on a quote basis through the channel. Geographic reach is North America — primarily the United States with active distribution in Canada — and the entire product line is designed, engineered, and manufactured domestically for that market. Supporting programs include U.S. Boiler University contractor training (online plus live-fire sessions in PA and CT), a public Find a Contractor locator, an ENERGY STAR rebates and federal tax credit resource center, and a dedicated distributor customer service portal.
