Raritan Water Heaters

Raritan Water Heaters provide hot water for galleys and showers. Dense foaminsulation provides better and longer heat retention than traditional fiberglass. The tank itself is protected by a 75 PSI T&P (temperatureand pressure) relief valve. The cylindrical design of the tank enables it to withstand more pressure than a cube shaped tank. Heat exchanger models can be connected to the engine cooling system. This provides the added convenience of hot water underway or when generator power is not available.
