Raritan Engineering 172011 20 Gallon Marine Water Heater with Heat Exchanger 120V

The Raritan Engineering 1700 Series marine water heater delivers reliable hot water for your galley and shower needs, whether you're docked or underway. This 20-gallon model features both 120V electric heating and an integrated engine heat exchanger, allowing you to generate hot water using shore power or your vessel's engine cooling system.

Key Features:

• 20-gallon capacity with glass-lined steel tank construction for superior durability and corrosion resistance
• Dual heating options: 120V electric element plus engine heat exchanger (over 7 feet of coiled tubing for rapid, efficient heating)
• Dense CFC-free foam insulation provides superior heat retention compared to traditional fiberglass
• Ignition-protected thermostat factory set to 120°F, adjustable from 110°F to 160°F with 190°F safety shutoff
• Cylindrical tank design withstands higher pressure than rectangular tanks
• 75 PSI temperature and pressure relief valve for safety
• Replaceable magnesium anode rod protects tank and neutralizes water acidity
• Corrosion-resistant polymer jacket built for harsh marine environments
• Same-side plumbing connections simplify installation: 3/4" male NPT for hot/cold water, 3/4" female NPT for heat exchanger

Benefits:

• Hot water availability even when generator power is unavailable—heat exchanger utilizes engine waste heat
• Retrofits easily to most onboard pressure water systems
• Glass-lined steel construction offers better longevity than stainless steel in marine applications
• Hand-assembled and individually tested for quality assurance
• Backed by 5-year limited warranty on tank, 2-year limited warranty on complete unit

Ideal for cruisers and liveaboards who demand consistent hot water performance in the demanding marine environment. The innovative heat exchanger coil ensures you'll have hot water after extended motoring, while the electric element provides convenience at the dock.
