The Raritan 20-Gallon Water Heater with Heat Exchanger is a top-of-the-line solution for anyone seeking a reliable and efficient way to access hot water on board. As part of the esteemed 1700 Series, this water heater is designed to provide hot water for galley and shower needs, making it an essential component of any marine vessel. The unit's dense foam insulation ensures better and longer heat retention than traditional fiberglass, ensuring that you have a steady supply of hot water whenever you need it.

The tank itself is protected by a 75 PSI T&P (temperature and pressure) relief valve, providing an added layer of safety and security. The cylindrical design of the tank enables it to withstand more pressure than a cube-shaped tank, making it a durable and reliable option for marine use. What's more, the heat exchanger models can be connected to the engine cooling system, providing the added convenience of hot water when underway or generator power is not available.

The innovative heat exchanger is over seven feet in length and is evenly coiled throughout the interior of the tank, providing hot water rapidly and efficiently. Additionally, Raritan's water heaters use an ignition-protected thermostat, which is factory set to 120°F but is adjustable from 110° to 160°F, with a safety shut-down limit of 190°F. This thermostat ensures that you have complete control over the temperature of your hot water, while also ensuring your safety and security.

The plumbing connections on the Raritan 20-Gallon Water Heater are located on the same side, simplifying installation and reducing the risk of leaks or other issues. The hot and cold water connections are 3/4" male NPT (National Pipe Thread), while the heat exchanger connections are 3/4" female NPT. This makes it easy to connect and disconnect the unit as needed, reducing downtime and maintenance costs.

In terms of construction, the Raritan 20-Gallon Water Heater features a glass-lined steel tank that is more durable than stainless steel, ensuring a long and trouble-free service life. The attractive polymer jacket resists corrosion from dampness, while the replaceable magnesium anode protects the tank and neutralizes acids in the water. The unit is also covered by a five-year Limited Warranty, with each unit assembled by hand, individually tested, and backed by Raritan's two-year Limited Warranty and legendary technical support team.

Overall, the Raritan 20-Gallon Water Heater with Heat Exchanger is a premium solution for anyone seeking a reliable and efficient way to access hot water on board. With its durable construction, innovative heat exchanger, and adjustable thermostat, this unit is sure to provide years of trouble-free service, making it an essential component of any marine vessel. Whether you're a seasoned sailor or a recreational boater, this water heater is sure to meet your hot water needs, providing you with the comfort and convenience you deserve on the water.
