The Raritan 12-Gallon Water Heater without Heat Exchanger (Model 171202) is purpose-built for serious cruisers and liveaboards who demand reliable hot water underway without relying on engine cooling systems. Whether you're anchored for days in a remote cove or running extended offshore passages, this 240V electric unit delivers consistent, on-demand hot water independent of engine operation. Unlike integrated heat exchanger models, this standalone design gives you complete control over water temperature and eliminates the dependency on running your main engine just to shower—a critical advantage when fuel conservation and engine rest matter.
This 12-gallon capacity model operates on 240V AC power, making it ideal for vessels with robust electrical systems or those regularly docked at shore power stations. The absence of a heat exchanger means the heating element works directly on potable water, simplifying maintenance and reducing corrosion points common in salt-water environments. The compact footprint and lightweight construction (1 lb) make it feasible for retrofit installation in tight galley spaces where bulkier units simply won't fit. Raritan's engineering ensures even heat distribution, preventing cold-water surges and delivering the steady water temperature serious cruisers expect during extended use.
This unit performs best aboard cruising sailboats, trawlers, and motor yachts equipped with 240V shore power systems or substantial battery banks with inverters rated for continuous 240V loads. Installation requires proper electrical wiring, a dedicated 240V circuit breaker, and integration into your vessel's potable water system downstream of your main tank—standard for any marine water heater installation. The 12-gallon reservoir ensures sufficient hot water for multiple showers or extended galley work without waiting for reheat cycles, a practical consideration for crews of two or more. Verify your vessel's electrical capacity and water system pressure ratings before purchase; this heater pairs seamlessly with Raritan's modular marine plumbing ecosystem.
