What Ace Heaters does
Ace Heaters, LLC is a U.S.-based commercial and industrial water heating equipment manufacturer headquartered in Corona, California, with operational roots dating to the 1930s and currently operating as a subsidiary of The Nudyne Group LLC, a third-generation privately held conglomerate that also owns Hubbell, Vaughn, Reco, Warren, and Howard's Engineering. The company designs and builds a focused product line including semi-instantaneous water heaters (Mini-Pack), packaged storage water heaters (Mega-Pack), ASME potable water storage tanks (S-Series), unfired clean steam generators, atmospheric and high-efficiency condensing boilers (B Series, Ajax E Series, Liberty Series), and replacement U-tube bundles, with proprietary semi-instantaneous and condensate sub-cooling technology delivering up to 99%+ thermal efficiency and ±4°F temperature control. Manufacturing is performed in the U.S. using ASME-certified construction and non-proprietary parts, with applications in healthcare, hospitality, education, pharmaceutical manufacturing, sports venues, museums, correctional facilities, and federal/defense facilities.
The business operates a sales-led, quote-based commercial model with no direct e-commerce; products are specified and sold through a network of 50+ authorized sales representative firms covering all U.S. states plus international markets (Canada, Mexico, Colombia, and Asia), supported by a dedicated rep portal, technical white papers, and case-study content targeting consulting engineers and facility managers. Revenue is generated primarily through one-time hardware sales of custom-engineered systems and recurring replacement tube bundle orders, with the May 2024 asset acquisition of Howard's Engineering Heat Transfer Products Corp. extending the portfolio into industrial steam and water-to-water process heating. The company has no disclosed revenue, no funding history, and operates with 11-50 employees.
