Whale Seaward 11 Gallon Hot Water Heater w/Front Heat Exchanger - Galvanized Steel - 120V - 1500W

The Whale Seaward 11 Gallon Hot Water Heater with Front Heat Exchanger is designed specifically for marine applications, providing reliable on-demand hot water for extended cruises, fishing expeditions, and liveaboard vessels where shore power is available. Built by Whale Marine, a trusted name in marine plumbing systems, this 120V unit ensures comfort during cold-water washdowns and showers in temperate or cooler climates.

Constructed from galvanized steel for corrosion resistance in saltwater environments, the Whale Seaward employs a front-mounted heat exchanger that efficiently utilizes waste engine heat to maintain water temperature while underway. The 1500W electric heating element activates when the vessel is docked or anchored, allowing the unit to reach its full 11-gallon capacity without delay. This dual-mode approach minimizes energy draw and fuel consumption while maximizing hot water availability.

Anglers and cruisers who spend extended time away from the dock will benefit most from this system, as the 11-gallon reservoir can supply multiple showers or galley tasks without rapid depletion. Installation requires 120V shore power access and basic plumbing connections to both the engine cooling circuit and hot water distribution lines, making it a practical choice for marine environments.
