Whale Seaward 6 Gallon Hot Water Heater w/Rear Heat Exchanger - White Epoxy - 120V - 1500W

The Whale Seaward 6 Gallon Hot Water Heater with Rear Heat Exchanger is purpose-built for marine vessels that demand reliable hot water in demanding saltwater environments. This 120V, 1500W electric water heater combines efficient heating capacity with corrosion-resistant construction, making it an essential upgrade for cruising boats, fishing vessels, and cabin cruisers where freshwater comfort matters.

The white epoxy-coated aluminum case provides superior protection against salt spray and marine atmospheric corrosion—a critical consideration for any system installed in engine rooms or exposed deck areas. The rear heat exchanger design enables integration with existing engine cooling loops, allowing the water heater to draw waste heat from the engine and reduce electrical load during underway operation. The 6-gallon capacity supplies adequate hot water for galley use, showers, and washing without requiring excessive storage space in tight marine environments. At 1500W of heating power, the unit reaches target temperatures efficiently while remaining compatible with standard 120V marine electrical systems.

This heater suits cruising boats, fishing vessels, and offshore yachts where fresh water and comfort are valued but space and electrical draw are constraints. Weekend fishermen appreciate the compact footprint for cabin vessels; serious offshore anglers benefit from the waste-heat exchanger feature that reduces fuel consumption during extended trips. The robust epoxy coating ensures years of reliable service in harsh marine conditions where uncoated aluminum would corrode rapidly.

Whale Marine water heaters are engineered to withstand the corrosive marine environment, making the Seaward 6 Gallon model a dependable choice for boat owners who prioritize durability and self-sufficiency at anchor. Installation requires basic plumbing and electrical work; consult your vessel's wiring diagrams to confirm 120V circuit capacity and heat exchanger compatibility with your engine cooling system.
