Laars Heating Systems

What Laars Heating Systems does

Laars Heating Systems is a Rochester, New Hampshire-based manufacturer of hydronic heating equipment founded in 1948 by engineer Avy Miller, operating today as a wholly-owned subsidiary of Bradford White Corporation. The company designs and builds residential and commercial boilers, combination boilers, tankless and indirect water heaters, commercial pool heaters, electric boilers, heat-pump water heaters, and accessory tanks, in capacity ranges from 50,000 to 5,000,000 BTU/hr across more than 20 product lines including FT Series, NeoTherm, MagnaTherm (FT and HTD), Pennant, Mighty Therm, LT Series, Laars-Stor, and E-Therm. Core technology centers on proprietary heat-exchanger designs — including low-mass stainless steel firetube construction and finned copper-tube legacy designs — combined with a proprietary control stack (Laars Linc touch-screen, Tru Trac oxygen trim, VARI-PRIME variable-speed pumping, DHW Smart Priority) and BMS/BACnet integration hardware (M4-LHS, S8, X-BAC, FieldServer gateway).

Laars sells exclusively through a two-tier channel: manufacturer representatives serving enterprise/specifying-engineer accounts, with fulfillment through a nationwide network of wholesale distributors, the tiered LaarsPro contractor loyalty program, and Certified Service Centers for warranty work. Direct-to-consumer and direct-to-contractor sales are explicitly avoided. The footprint spans the United States, Canada (Halton Hills ON, served via Bradford White Canada with bilingual support), and Mexico (via Heating Systems Mexico). Products are manufactured at the 20 Industrial Way Rochester NH headquarters plant, with additional manufacturing capacity in Monticello MN following the January 2024 acquisition of Electro Industries — a deal that pulled Laars into electric boilers and heat-pump water-heater technology.

The end-customer mix spans commercial and institutional buildings (office, education such as Marquette University High School and Hofstra, hospitality such as JW Marriott Dallas, healthcare such as Ronald McDonald House New York, multi-family residential including luxury Boston and Salt Lake City high-rises, and government such as the Ohio State Police Academy) plus single-family residential via contractor-installed residential boilers. Revenue is generated almost entirely through hardware sales via the channel, with no recurring software or service ARR product evident. Recent strategic emphasis is on electrification: the AHR Expo 2026 showing introduced ElectriFLEX MD, AeroTherm G2, eF XT, eF Series Turbo, and Infiniti product lines.

Broad incumbents

• Viessmann: Viessmann is a broad incumbent — global hydronic heating manufacturer with condensing boilers, heat pumps, and combined heat & power. Overlaps with Laars' commercial and residential boiler portfolio, but Viessmann has materially broader European footprint and deeper heat pump catalog.
• Rinnai: Rinnai is a broad incumbent in tankless water heaters and combi boilers for residential and commercial markets. Both share a Japanese heritage of high-efficiency condensing technology and contractor-channel distribution in North America.
• A. O. Smith: A. O. Smith is a broad incumbent in residential and commercial water heaters (gas, electric, tankless, heat pump) with significant overlap to Laars' water heating portfolio. A. O. Smith operates at materially larger scale with global manufacturing footprint.
• Bosch Thermotechnology: Bosch Thermotechnology is a broad incumbent in residential and commercial boilers, water heaters, and heat pumps. Overlap with Laars' wall-hung boilers, combi boilers, and commercial condensing lines, but Bosch operates at significantly greater scale and broader product breadth.

Direct peers

• Burnham Holdings: Burnham Holdings owns U.S. Boiler Company, Burnham, and Crown — all direct competitors in cast iron and condensing boilers for residential and commercial hydronic markets. Highly comparable go-to-market via wholesale distributors and contractor networks.
• IBC Technologies: IBC Technologies manufactures modulating condensing boilers (VFC and SL Series) for commercial applications. Direct overlap in high-efficiency hydronic boiler technology, cascade systems, and North American contractor/specifier distribution.
• Lochinvar: Lochinvar is a direct peer in high-efficiency commercial condensing boilers and water heaters (e.g., FTXL, Knight, Crest). Both compete head-to-head in the commercial specification channel with overlapping condensing firetube, BMS integration, and cascade capability offerings.
• Weil-McLain: U.S. Boiler Company / Weil-McLain is a direct peer — both manufacture hydronic and condensing boilers for residential and light commercial markets, sold through wholesale distribution and contractor channels in North America. Overlapping product categories include wall-hung and floor-standing cast iron, stainless steel firetube, and modulating condensing boilers.
• Navien: Navien is a direct peer in residential and commercial condensing combination boilers and tankless water heaters. Both sell exclusively through plumbing/HVAC contractor channels and compete on stainless steel heat exchangers and high-efficiency modulation.
• HTP (Heat Transfer Products): HTP is a direct peer in high-efficiency residential and commercial boilers, indirect water heaters, and tankless water heaters. Overlap in stainless steel firetube design, modulating combustion, and contractor-channel distribution makes it a close comparable.
