The Diesel Heater 30 Viking Combi 12V is built for serious boaters who want reliable warmth without sacrificing space or battery life. Designed specifically for outboard engine boats, this compact unit heats cabin air and the onboard hot water tank (boiler size recommended 25 L), delivering comfort where you need it most—whether you’re cruising in chilly mornings or preparing for a cozy night aboard.

Smart, efficient, and quietly powerful

• Low-voltage start begins at 9.6 V, so you can rely on a modest 12 V system without draining your battery.
• Low amperage operation consumes only 0.4–2.6 A, enabling warmth even on boats with smaller battery banks.
• Laminar combustion delivers clean, efficient flames with reduced exhaust noise, helping you keep the marina neighbor-friendly and your cabin serene.
• Very low surface temperatures on the unit and exhaust pipe enhance safety and allow flexible installation closer to living spaces.
• Green boost burner promotes cleaner burning and better fuel efficiency for extended trips.

Powerful, flexible heating for air and water

The Viking Combi delivers steady warmth across a broad range: 950–2500 W of heating output, with a capacity to heat between 33 and 73 cubic meters per hour. It can split heat between air (50–90%) and water (10–40%), enabling simultaneous cabin comfort and hot water supply for showers or galley needs. This makes it a practical all-in-one solution for boats where space and weight matter.

Advanced control, modern connectivity

Equipped with a new PCB and an advanced control panel, the Viking Combi moves beyond basic warmth. It supports Bluetooth and WiFi connectivity, RPM-controlled fans for optimal performance, and program updates to refine how it heats your space over time. It’s designed to work with the Askeladden C-command screen, offering intuitive, on-demand control from a familiar interface. A detachable Bluetooth thermostat beacon adds flexible, wireless temperature management—perfect for adjusting comfort from anywhere aboard.

Future-ready and easy to install

With intelligent temperature control at its core, the heater optimizes both heating and fresh air exchange for a healthier cabin environment. The system offers a floor or wall installation option, letting you choose the layout that best fits your vessel’s interior. It’s designed with future program options in mind, so you can benefit from enhancements without replacing the unit. Silent operation means peaceful nights at anchor or a quiet passage through open water, letting you enjoy the surroundings without engine-room noise intruding on your crew’s downtime.

Ideal use cases and who should consider it

• Boat owners with outboard engines who need reliable cabin warmth and hot water without adding a bulky heater footprint.
• Yacht or fishing vessel owners seeking a 12V diesel heater that can run on modest battery capacity during weekend trips or extended cruising.
• Mariners who value low emissions, cleaner burning, and a system that stays comfortable in varying weather conditions.
• Users who want seamless integration with existing marine control screens (Askeladden C-command) and future-ready software updates.
