Raritan Engineering 171211 12 Gallon Marine Water Heater with Heat Exchanger 120V

The Raritan Engineering 171211 is a 12-gallon marine water heater designed specifically for the demanding conditions of life on the water. This dual-source heating system provides reliable hot water for galley and shower applications on boats, yachts, and other marine vessels.

Dual Heating System:

This model features both electric heating and an integrated heat exchanger, offering maximum flexibility for hot water production. The 1250-watt electric heating element operates on 120V AC power when dockside or running a generator, delivering a recovery rate of 13 gallons per hour. The heat exchanger allows you to heat water while underway by circulating engine coolant through the 7-foot coiled tube inside the tank, ensuring hot water is always available without consuming generator power.

Key Features:

• 12-gallon capacity glass-lined steel tank for superior corrosion resistance and longevity
• Corrosion-resistant polymer exterior jacket that will not rust or corrode from marine dampness
• High-density CFC-free foam insulation maintains water temperature longer than traditional fiberglass insulation
• Replaceable sacrificial magnesium anode protects tank and neutralizes acids in water
• Ignition-protected adjustable thermostat (factory set at 120°F, adjustable 110°-160°F)
• 75 PSI temperature and pressure relief valve for safe operation
• Cylindrical tank design withstands more pressure than square tanks
• Hot and cold water connections: 3/4" male NPT
• Heat exchanger connections: 3/4" female NPT

Built for Marine Durability:

Each unit is hand-assembled and individually tested to ensure trouble-free operation in harsh marine environments. The glass-lined steel tank construction has proven more durable than stainless steel alternatives, while the impact-resistant polymer jacket resists damage during installation and handling. The compact cylindrical design fits easily into tight marine spaces and retrofits to most onboard pressurized water systems.

Backed by Raritan's 5-year limited warranty on the tank and 2-year limited warranty on the complete unit, plus legendary technical support from a company with over 65 years of marine product experience.
