Whale F700/F600W 6 Gallon 120V Marine Water Heater with Front Heat Exchanger - Stainless Steel or White Epoxy

The Whale F700 and F600W are 6 gallon, 120V marine water heaters built to deliver reliable onboard hot water for galleys, heads, and showers. Both models use a front-mounted, double-wall heat exchanger that keeps the freshwater supply physically isolated from the engine heating circuit, so you get safe, code-compliant hot water whether you are docked and running on shore power or underway drawing heat from the engine. Rated to 100 PSI and finished for the marine environment, this line is available in a durable stainless steel tank (F700) or a white epoxy-coated tank (F600W) to match your onboard finishes and budget.

Installation is straightforward in a horizontal orientation, and the compact 13 x 19 x 13 inch footprint fits the tight lockers and lazarettes typical of cruising boats. Each unit is ignition protected for safe installation in gasoline-powered engine spaces, and the 1500 watt 120V heating element brings a full tank up to temperature efficiently at the dock.
