Whale Seaward 11 Gallon Hot Water Heater - White Epoxy - 240V - 4500W

The Whale Seaward 11 Gallon Hot Water Heater in white epoxy finish delivers reliable hot water supply for modern marine vessels operating on 240V electrical systems. Rated at 4500W, this electric water heater is engineered specifically to endure the corrosive salt-air environment and demanding conditions found aboard fishing boats, cruisers, and offshore vessels where conventional freshwater systems must handle continuous use in harsh marine conditions.

The white epoxy-coated aluminum construction resists saltwater corrosion and integrates seamlessly into engine room installations alongside existing marine equipment. The 11-gallon capacity provides adequate hot water reserves for galleys, heads, and washdown stations without excessive weight penalties—critical considerations in vessel design where every pound affects performance and fuel economy. At 23.5 lbs and compact dimensions of 17 x 17 x 26 inches, the Seaward 11 fits into space-constrained engine compartments typical of modern sport fishermen and cruising yachts. The 4500W heating element achieves efficient recovery time between usage cycles, minimizing the drain on onboard electrical systems and battery banks.

Whale Marine water heaters serve working fishing boats, weekend cruisers, and extended-range offshore vessels where dependable freshwater heating is essential for crew comfort and operational efficiency. Serious anglers appreciate systems that reduce reliance on generator runtime, while liveaboard boaters depend on consistent hot water for daily operation. This unit is purpose-built for marine electrical systems operating at standard 240V three-phase shore power or dedicated onboard electrical plants found on larger vessels.

Marine electric water heaters represent a proven alternative to direct-fire heating systems, offering simpler installation, lower maintenance, and better safety integration with modern marine electrical standards. The Seaward 11 (part number S1150EW-4500) is optimized for vessels where weight, space, and reliability cannot be compromised.
