Enjoy hot water on your boat with a dependable Seaward Water Heater.

Heat water dockside with 120V AC power or when underway, using engine heat. This water heater features an ignition-protected design, cladded aluminum tank, dual-wall heat exchanger and stainless steel case. Heat exchanger ports are located at the “Rear”, on the side opposite the electrical box and cold in/hot out ports. To protect against galvanic corrosion and extend tank life, use of a magnesium anode is highly recommended. For installation and maintenance, see the Seaward Water Heater Owner’s Manual.
