Description

The Wallas Viking Water is a compact diesel-powered water heater, designed to provide hot water and heating for marine and vehicle installations. Built as the most efficient solution for off-grid use, it delivers reliable performance while running directly from the main fuel tank, removing the need for gas systems, high electrical demand or separate fuel tanks.

Designed with Wallas’ latest Greenboost burner technology, the Viking Water optimises fuel and electrical consumption while delivering clean, efficient combustion. The fully enclosed laminar burning process keeps indoor air clean and odour-free, while the system can heat domestic hot water or power underfloor heating and radiators. Remote access via the Wallas mobile app also allows the heater to be started before arrival, ensuring hot water and a warm interior when you get there.

Key Features

• Wireless sensor for improved accuracy (room temperature sensor)
• Both heaters come with a 5 W brushless motor water pump and can run the 15 W water pump as well for longer coolant runs
• Combustion air drawn from outside and exhaust safely expelled outside the vehicle or vessel
• Remote operation and monitoring via the Wallas mobile app
• Advanced control panel with intelligent temperature management
• Ultra-low CO₂ and NOx emissions
• Durable Finnish design
• Advanced Control

Its typical electrical consumption of 0,6–1,0 A at 12 V significantly reduces the need for large inverters and extensive battery capacity compared to electric heating, saving system weight and offering a comparable overall cost for off-grid setups.
