2,000 feet below the ocean's surface. That's how deep naval submarines can navigate, plunging into the silent, shadowy depths of the ocean. Since 1952, every U.S. Navy submarine has been equipped with Hubbell marine water heaters. And since 1945, most surface combatant naval vessels have trusted our products.

Defense-grade. Hubbell water heaters are fortified with the high-grade material options like HydraStone™cement lining, 316L stainless steel, or 90/10 copper-nickel for long-lasting performance. Our maritime solutions meet the standards set by UL, CSA, USCG, ABS, DNV, ASME, NR13, and MIL as applicable. They're proudly built in ISO 9001:2015 certified facilities in the U.S. (containing imported components and Buy American Act compliant).

Hubbell has been involved in various naval programs and initiatives including: DDG-51, DDG-1000, LPD, FRC, NSC, T-AKE, T-AO, T-AKR, LCS, LHD/LHA, LSD, MCM, BP, WLB, WLM, CG, WAGB, MLP, CVN, YRBM, APL. Hubbell water heaters perform reliably in the most extreme environments. As a defense distributor/contractor, we're committed to ensuring our armed forces are mission-ready with long-lasting equipment.
