Raritan Water Heater 1700 – Reliable, Efficient Marine Hot Water for Every Voyage
Designed for life at sea, the Raritan Water Heater 1700 Series delivers dependable hot water with robust construction, efficient performance, and a space-saving footprint ideal for marine environments. Whether you're cruising offshore, docked in a marina, or anchored in a quiet cove, this marine-grade water heater ensures that hot water is always available—safely, quickly, and without hassle.
Built for long-term durability, the 1700 Series features a corrosion-resistant stainless steel tank, high-density insulation, and an optional engine heat exchanger for dual-source heating. Its compact design allows for flexible installation in tight spaces, making it a top choice for sailboats, powerboats, and yachts alike.
Engineered for Marine Conditions
Unlike residential models, the Raritan Water Heater is built specifically to endure the harsh marine environment. Every component—from the tank to the thermostat to the heating element—is carefully selected and tested for performance, longevity, and corrosion resistance.
The stainless steel inner tank is pressure-tested and backed by Raritan’s reputation for reliability. The high-density foam insulation keeps water hot longer, reducing the frequency of reheating cycles and conserving energy while underway.
Efficient Heating with Multiple Power Options
The 1700 Series operates off a pressurized water system and offers flexibility through electric heating, engine heat exchanger capability, or a combination of both. This means you can heat water using AC shore power or onboard generator power while docked, and switch to engine-based heating when underway—ensuring hot water is always on hand.
The fast recovery element ensures rapid heating and quick replenishment, so even with limited tank size, you’re not left waiting for the next warm shower.
Compact Design, Seamless Installation
Space is at a premium on any vessel. The Raritan Water Heater 1700 is designed with a compact, low-profile form factor that allows it to fit neatly into tight mechanical spaces. It connects easily to standard plumbing and requires only a pressurized freshwater system to function.
The intuitive layout and marine-grade fittings simplify installation and future service, giving both owners and marine professionals confidence in its setup and operation.
Safety Meets Performance
Raritan incorporates reverse-polarity protection, temperature regulation, and pressure relief systems into the 1700 Series for safe, worry-free use. You get consistent, clean, hot water—without the risks associated with unregulated heat or electrical exposure in marine environments.
Trusted by Boaters Worldwide
From liveaboards to weekend cruisers, Raritan’s water heaters have become a staple in marine systems worldwide. With a focus on longevity, low maintenance, and real-world performance, the 1700 Series is engineered to keep up with the demands of life on the water.
