Efficient 5kW Water Heating for Marine Comfort.
HYDRONIC S3 D5E
The Modern Standard for Marine Heating Upgrade your boat with the Eberspacher Hydronic S3 D5E, the latest evolution in compact 5kW water heating. Designed to integrate seamlessly into your vessel's coolant system, it provides powerful, consistent heat to radiators and matrix blowers throughout your cabins and saloon. Additionally, it connects effortlessly to a calorifier, ensuring you have a reliable supply of hot water for showers and the galley, bringing the comforts of home to your life at sea.
Stepless Control & Whisper-Quiet Operation Enjoy a peaceful environment on board thanks to the S3's advanced "stepless" heating control. Unlike older models that cycle noisily between high and low, this intelligent system modulates its output smoothly from 1.3kW to 5kW to maintain a steady temperature. Combined with the new, ultra-quiet Eberspacher digital dosing pump and optimized marine exhaust silencers, the S3 offers an almost silent operation, perfect for undisturbed sleep in the marina or at anchor.
Reliable & Efficient for Long Voyages Built for durability and efficiency, the Hydronic S3 features a robust brushless fan motor and a service life of up to 3,000 hours. It utilizes residual heat from the engine to save fuel and can also pre-heat the engine before you set sail, reducing wear during cold starts. Compatible with the modern EasyStart Pro controller and ready for CAN bus integration, this heater offers precise diagnostics and control, ensuring your marine heating system is both smart and dependable for years to come.
Compact 5kW Water Heating: All-in-One Efficiency
HYDRONIC D5 WSC
Space-Saving Design for Tight Engine Bays Maximize the available space on your vessel with the Eberspacher Hydronic D5WSC, the ideal "Compact" water heater for marine applications. Unlike standard modular heaters, the D5WSC cleverly integrates the water pump and fuel metering pump directly inside the unit's housing. This all-in-one design significantly reduces the installation footprint, making it the perfect choice for crowded engine rooms or smaller boats where mounting space for external components is limited.
Powerful Heating & Hot Water on Demand Despite its small stature, the D5WSC packs a punch, delivering a full 5kW of heat output. It integrates seamlessly into your boat’s coolant circuit to heat radiators and blower matrix units, ensuring a warm and dry cabin environment. Crucially, it can also be plumbed into a calorifier, providing you with a reliable supply of domestic hot water for showers and washing up, effectively turning your boat into a comfortable floating home.
Simplified Installation & Robust Protection The integrated nature of the D5WSC simplifies the installation process by reducing the number of external parts and wiring connections needed. This not only makes for a neater, faster fit but also offers better protection for critical components like the fuel pump, shielding them within the robust heater casing. Combined with Eberspacher’s proven reliability in marine environments, this compact unit offers a durable and efficient heating solution for sailing yachts and motorboats alike.
High-Capacity Heating for Large Yachts & Commercial Vessels
HYDRONIC M2
The Powerhouse for Larger Vessels When standard heaters aren't enough, the Eberspacher Hydronic M2 (MII) steps up. Available in powerful 8kW, 10kW, and 12kW variants, this heavy-duty hydronic system is engineered specifically for larger boats, yachts, and commercial vessels. Its high output capacity ensures it can effectively heat large volumes of coolant, making it capable of warming spacious saloons, multiple cabins, and even the engine bays of substantial marine craft.
Comprehensive Heating & Hot Water The Hydronic M2 is the heart of a complete onboard comfort system. By integrating with your vessel's coolant circuit or a dedicated heating loop, it powers extensive radiator networks, underfloor heating, and large matrix blowers to eliminate damp and cold. Furthermore, its significant thermal power makes it ideal for heating large calorifiers, guaranteeing an abundant supply of hot water for showers, galleys, and deck washes, ensuring luxury comfort for everyone on board.
Commercial-Grade Reliability Derived from robust commercial vehicle technology, the M2 series is built to withstand the rigors of continuous operation. It features a brushless motor for extended service life and is designed for ease of maintenance. With biodiesel-compatible versions (like the M2 D12L) available, it offers flexibility for modern fuels. Whether crossing oceans or moored in a winter marina, the Hydronic M2 delivers the reliable, heavy-duty performance required for serious marine applications.
