Raritan 12-Gallon 120V Marine Hot Water Heater

The Raritan 12-Gallon 120V Marine Hot Water Heater gives stored hot water for onboard galley and shower use. Its cylindrical tank design is built to handle pressurized freshwater service, while dense foam insulation helps retain heat longer between heating cycles.

The 120V electric element gives hot water from shore power or generator power. This model is supplied without an engine heat exchanger, so it is a straightforward electric-only solution for boats that do not need engine-coolant-assisted water heating.

Confirm available space, electrical supply, circuit protection, freshwater plumbing, pressure-relief routing, and drain access before installation. Support the heater securely, follow all wiring and pressure-relief requirements, and fill the tank completely before energizing the element to avoid damage.
