Common Concerns Answered
Some users report thermostat accuracy issues.
Ensure the thermostat is properly calibrated during installation and maintenance. Following the manual's guidelines will optimize temperature regulation for consistent hot water output.
The engine heat exchanger takes time to produce hot water initially.
The engine heat exchanger relies on engine coolant circulation. Allow sufficient engine run time after startup to achieve optimal water temperature, especially during initial heating cycles.
Installation complexity for the heat exchanger connections might deter DIYers.
While requiring basic plumbing knowledge, the heat exchanger connections are straightforward. Referencing the provided installation manual (https://www.raritaneng.com/wp-content/uploads/2019/09/1700-Series-Water-Heater-Manual.pdf) is recommended; professional installation is advised for those unfamiliar with marine systems.
Frequently Asked Questions
How does the engine heat exchanger work on this Raritan water heater?
The engine heat exchanger draws hot coolant from your vessel's engine and circulates it through a series of coiled tubes inside the water heater tank. This heat transfer process warms the potable water within the tank without directly consuming engine power beyond the coolant circulation.
What is the temperature range for the adjustable thermostat?
The ignition-protected thermostat is adjustable between 110°F and 160°F, allowing you to set your desired hot water temperature for galley use or showering.
What is the pressure rating of the T&P relief valve?
The unit is equipped with a 75 PSI Temperature and Pressure (T&P) relief valve, designed to safely release excess pressure or temperature from the tank.
What are the plumbing connection sizes for this unit?
The hot and cold water connections are 3/4" male NPT. The engine heat exchanger connections are 3/4" female NPT.
How long is the warranty on this Raritan water heater?
The Raritan 12-gallon hot water heater comes with a 5-year limited warranty on the tank and a 2-year limited warranty on the overall unit.
