Superior Marine Water Heating Performance

The Raritan 1700 Series Water Heater is designed to deliver reliable hot water for onboard galleys and showers, ensuring comfort while at sea. Engineered with dense foam insulation, it provides superior heat retention compared to traditional fiberglass insulation, reducing energy consumption and extending warm water availability. The tank is safeguarded by a 75 PSI temperature and pressure relief valve, ensuring safe operation under marine conditions.

The cylindrical design enhances the tank’s durability, allowing it to withstand higher pressure compared to cube-shaped tanks. For added convenience, heat exchanger models can be integrated with the engine’s cooling system, supplying hot water even when underway or when generator power is unavailable. The built-in heat exchanger is over seven feet long and evenly coiled throughout the tank, ensuring rapid and efficient heating.

Advanced Safety and Efficiency Features

The Raritan 1700 Series Water Heater includes an ignition-protected thermostat for enhanced safety. Factory-set at 120°F, the thermostat can be adjusted between 110°F and 160°F, with a safety shut-off limit at 190°F. Designed for straightforward installation, all models feature plumbing connections on the same side, making integration into onboard systems seamless.
