WHALE Seaward Marine & RV Hot Water Heaters

The WHALE Seaward family of marine and RV hot water heaters includes 3 and 6 gallon models designed to withstand harsh marine conditions. Available in 12V/300W and 120V/1500W configurations, these heaters feature double-walled heat exchangers, integrated temperature and pressure relief valves, hold-down brackets welded to the inner tank, and ignition protected designs. Case options include white epoxy-coated aluminum, galvanized steel, and stainless steel to offer varying levels of corrosion resistance and finish. Units are robustly manufactured with sturdy exteriors; magnesium anodes are available separately to help prevent corrosion and extend heater life. Some models specify double-walled exchangers with a 100 psi rating and front or rear heat exchanger arrangements to suit installation needs.
