Raritan Engineering 172001 20 Gallon Marine Water Heater 120V Without Heat Exchanger

The Raritan Engineering 1700 Series 20-gallon marine water heater delivers reliable hot water for galleys and showers on boats and RVs. This 120V model operates without an engine heat exchanger, relying on electric heating for consistent performance. The glass-lined steel tank features dense CFC-free foam insulation that provides superior heat retention compared to traditional fiberglass insulation, keeping water hot longer and reducing energy consumption.

Key Features:

• 20-gallon capacity with glass-lined steel tank for durability and corrosion resistance
• 120V electric operation with ignition-protected thermostat (factory set to 120°F, adjustable from 110° to 160°F)
• Dense foam insulation for superior heat retention and energy efficiency
• Cylindrical tank design withstands higher pressures than square tank configurations
• 75 PSI temperature and pressure relief valve for safety
• Hot and cold water connections: 3/4" male NPT on same side for simplified installation
• Corrosion-resistant polymer jacket designed for harsh marine environments
• Replaceable magnesium anode rod protects tank and neutralizes water acidity
• Safety shut-down limit at 190°F prevents overheating

Each Raritan water heater is hand-assembled and individually tested to ensure quality. The glass-lined steel construction offers greater durability than stainless steel alternatives, while the attractive polymer exterior resists corrosion from dampness and salt air. This model retrofits easily to most onboard pressure water systems. Backed by a five-year limited warranty on the tank and two-year limited warranty on components.
