Hubbell

The Hubbell Heater Company has functioned as a premier global authority in engineered water heating solutions since its founding in 1920. Headquartered in Stratford, Connecticut, the company remains a third-generation, family-owned American manufacturer. Hubbell serves as a primary infrastructure provider for the most demanding environments on earth—and at sea—supplying specialized water heaters for the US Navy, offshore oil platforms, nuclear power plants, and high-volume commercial kitchens.

The brand's technical identity is defined by its mastery of corrosion-resistant metallurgy and heavy-duty vessel engineering. A primary engineering hallmark is the use of HydraStone™ cement lining. Unlike standard glass-lined tanks that can crack or flake over time, Hubbell's HydraStone is a 1/2-inch thick, seamless cement coating that is centrifugally spun into the tank at 250 RPM. This creates a tank that is essentially impervious to the corrosive effects of hot water, eliminating the need for sacrificial anode rods and often extending the equipment’s lifespan to double or triple that of conventional units.

Innovation at Hubbell is concentrated on "Application-Specific" logic and extreme-environment durability. Key technical pillars across the portfolio include:

• Incoloy® Sheathed Elements: Standard across their electric lines, these heating elements utilize a high-nickel-chromium alloy. This provides superior resistance to scale buildup and high-temperature oxidation, ensuring the heater maintains 98%+ thermal efficiency even in "hard water" regions.
• Non-Ferrous Tappings: Every connection point on a Hubbell tank utilizes solid copper-silicon alloy threads. This prevents the "galvanic corrosion" that often occurs when plumbing dissimilar metals, ensuring that the tank's entry and exit points remain as durable as the vessel itself.
• TX and TXA Tankless Logic: A sophisticated digital control system that utilizes zero-cross firing and triac modulation. It calculates the exact power (kW) required based on real-time flow and temperature sensors, providing a +/- 1°F stability that is critical for industrial process systems and safety eye-wash stations.
• Steam-Fired STX Technology: A semi-instantaneous system utilizing a U-tube bundle design. This architecture allows for massive hot water recovery (up to 10,500 GPH) using a facility’s existing steam supply, featuring a baffled coil that optimizes heat transfer without the footprint of a massive storage tank.

Technical Note: Hubbell is one of the few manufacturers capable of building to MIL-spec requirements. Their naval heaters are engineered to withstand the extreme shock (MIL-S-901), vibration (MIL-STD-167), and electromagnetic interference (MIL-STD-461) required for life aboard an aircraft carrier or submarine.

The product portfolio is strategically categorized by energy source and specialized application:

• Electric Storage & Point-of-Use: Ranging from the Model SE (the commercial workhorse) to the CE series compact units designed to fit directly under a sink.
• High-Efficiency Tankless: Featuring the HX/TX series for commercial demand and the TXA for ASME-stamped industrial requirements, offering on-demand heating with zero standby heat loss.
• Indirect & Steam-Fired Systems: Including the Model STX and BWX, which utilize steam or boiler water to heat domestic water via high-efficiency heat exchangers.
• Foodservice Booster Heaters: Specialized J-Series electric units designed to provide the 180°F (82°C) final rinse water required for commercial dishwashing sanitization.
• Ultrapure & RO/DI Series: Constructed with 316L stainless steel pressure vessels specifically for laboratories, pharmaceutical plants, and microelectronics manufacturing.

The strategic value of Hubbell lies in its "Total Lifecycle" reliability. By maintaining its entire manufacturing footprint in New England, the brand provides a high-yield foundation for engineers who cannot afford a failure in critical infrastructure. This commitment to heavy-gauge construction—backed by their signature 10-year non-pro-rated warranties—makes Hubbell the foundational choice for operations where water heating is not just a utility, but a mission-critical component.
