Raritan Water Heater Thermostat Assembly

The Raritan Water Heater Thermostat Assembly is a replacement temperature-control component for compatible Raritan marine water heaters. It cycles electrical power to the heating element as needed to maintain the selected water temperature inside the tank.

The adjustable thermostat allows the water temperature setting to be changed within the supported range. Higher settings increase scald risk, so temperature should be selected carefully and coordinated with any mixing valve or other hot-water safety measures installed aboard the boat.

Verify water-heater model compatibility, electrical rating, thermostat location, wiring, and temperature setting before installation. Disconnect shore or generator power before opening the electrical panel, replace the component according to Raritan instructions, and confirm safe water temperature after the heater returns to service.
