Wallas® Viking Water Heater w/ Control Panel - 10.2K

The Wallas® Viking Water is a premium diesel-powered hydronic heating and hot water system designed for RVs, camper vans, expedition vehicles, and marine cabins. Combining quiet operation, clean-burning efficiency, and intelligent heat management, it delivers dependable all-season cabin heat alongside reliable domestic hot water for showers, sinks, and onboard living.

• Dual Intelligent Thermostat Control: Independently manages cabin coolant temperatures and domestic hot water temperatures for precise comfort and shower performance
• Variable-Output Diesel Burner: Automatically adjusts heat levels for quieter operation and reduced fuel consumption
• Sealed Combustion System: High Altitude Mode optimizes combustion performance for reliable operation in high-elevation environments

Unlike many conventional on/off heating systems, the Viking Water continuously modulates its output to maintain a more stable interior temperature and water heating performance. This results in quieter operation, lower fuel consumption, and more consistent comfort with fewer temperature fluctuations. The hydronic design allows heat to be distributed throughout the vehicle or vessel using multiple heat exchangers, making it especially effective for larger or multi-zone layouts operating in cold-weather conditions.

The Viking Water is engineered for modern overland, expedition, and marine installations where efficiency, durability, and multi-function capability are critical. Running on diesel or renewable HVO fuel, it integrates easily with existing fuel systems while eliminating the need for separate propane heating infrastructure. Summertime Mode allows the system to heat only domestic hot water without running cabin heat, providing efficient warm-weather operation when space heating is unnecessary. Combined with its compact Scandinavian-built design, low electrical consumption, and high-altitude capability, the Viking Water is exceptionally well suited for extended off-grid travel and four-season use where dependable performance matters most.
