Raritan Water Heater Thermostat Assembly

The Raritan Water Heater Thermostat Assembly (Model WH16) is the critical temperature control component for Raritan marine water heating systems. This thermostat assembly mounts behind the rectangular electrical panel and manages heating element operation, cycling power on and off to maintain consistent water temperature. It's an essential replacement or upgrade part for operators maintaining Raritan-equipped vessels or mobile field installations where reliable hot water supply is mission-critical.

The assembly features adjustable temperature settings, allowing users to dial in water temperature between lower and higher ranges depending on operational requirements and environmental conditions. Raritan engineers recommend keeping settings at or below 120 degrees to avoid scalding hazards during routine use. The thermostat's primary function is to regulate element power—opening and closing the circuit as needed to hold water at the user's selected setpoint. This cycling prevents overheating while ensuring rapid heat-up during cold-weather operations or extended field deployments where hot water availability affects crew readiness and sanitation protocols.

Operators of marine vessels, expedition vehicles, forward operating bases, and mobile command centers rely on Raritan water heating systems for practical hygiene and equipment maintenance. The WH16 thermostat is the wear component most likely to require replacement after extended service life. Weighing 0.45 pounds and measuring 7 × 1 × 8 inches, the assembly integrates directly into existing Raritan water heater housings. Verified OEM part number WH16 ensures proper fit and thermal performance without compatibility issues.
