The Whale Seaward 11 Gallon Hot Water Heater with Rear Heat Exchanger is purpose-built for cruising vessels, liveaboards, and serious anglers who spend extended time on the water and demand reliable hot water comfort. After years running the Gulf and Atlantic coastal routes, nothing ruins a trip like cold showers in harsh weather or overnight passages—this stainless steel unit delivers consistent, efficient hot water when you need it most.
Built from marine-grade stainless steel, the Whale Seaward model S1200 uses a rear heat exchanger design that maximizes thermal transfer from your engine cooling loop, reducing fuel consumption and electrical load compared to direct-element heating alone. The 1500-watt, 120-volt heating element provides supplemental warmth during idle periods or when the engine isn't running—critical for maintaining water temperature during extended anchorages or cold-weather layovers.
The 11-gallon capacity strikes an ideal balance for vessels up to 45 feet, providing sufficient hot water for showers, galley use, and deck washdowns without excessive weight or cabin space demands. Compact dimensions of 17 x 17 x 26 inches allow flexible installation in engine rooms, lazarettes, or galley lockers where space is premium. This heater is ideal for enhancing the comfort of your boating experience.
