Whale Seaward 11 Gallon Hot Water Heater w/Front Heat Exchanger - Galvanized Steel - 240V - 1500W

The Whale Seaward 11 Gallon Hot Water Heater with Front Heat Exchanger is a marine-grade water heating solution engineered to deliver consistent hot water in demanding saltwater environments. Built by Whale Marine with galvanized steel construction, this 240V electric unit produces 1500W of heating power and is specifically designed to withstand the corrosive conditions of offshore and coastal boating operations.

The 11-gallon capacity strikes a practical balance for cruising vessels and fishing boats, providing adequate hot water reserves without consuming excessive electrical load when underway or docked. The front-mounted heat exchanger configuration allows integration with engine cooling systems, offering dual-source heating capability that maximizes energy efficiency during extended trips. Galvanized steel outer construction resists rust and corrosion far longer than untreated materials, a critical consideration in salt-air exposure where standard steel fails within months. At 33.6 lbs and compact dimensions (17 x 17 x 26 inches), the unit fits tight engine compartments and cabin storage spaces found on sport fishermen, cruisers, and commercial fishing vessels alike.

This heater serves weekend anglers who need reliable fresh-water showers after days on the water, as well as serious offshore operators running multi-week expeditions. The front heat exchanger design reduces dependence on shore power or generator fuel, lowering operational costs on extended passages. Installation requires 240V electrical service and basic plumbing connections—standard configurations on most modern marine electrical systems.

Whale Marine's marine water heaters are purpose-built for saltwater use, addressing the material fatigue and corrosion failures that plague automotive or RV-grade heaters deployed aboard vessels. The galvanized steel option delivers durability and affordability for operators prioritizing longevity in harsh marine conditions over premium weight savings.
