Wallas 85 NDP diesel stove and heater

Durable Surface Mounted Diesel Stove and Heater for Boats

85 NDP makes a good option when you are looking for a stove for harsh weather conditions with a quick installation. Superb corrosion-free stainless steel and aluminum construction keep it intact for years. Cook your recipes on the left-side plate and simmer on the right at a slightly lower temperature. The stove is as easy as a press of a button to start and a stepless control for heat. Once you are done, simply wipe it down. The elegant-looking blower lid is a forced air heater and a protective cover for the ceramic surface. By lowering the lid, the stove begins to blow warm air for cabin heating.

Unlike other systems, Wallas diesel stoves draw combustion air from inside the cabin and direct exhaust safely outside. This feature forces fresh air to be drawn into the cabin area, drying the vessel interior and reducing the effects of mildew, while enriching the cabin with fresh air.



Cleaner Burning

Updated software optimizes fuel consumption

Calibrated to burn renewable fossil free diesel (e.g. HVO)

Larger burner burns fuel slower resulting in ultra low NOX emissions

Extensively tested with Neste

Improved burner efficiency for more power

The Greenboost burner burns renewable fossil-free diesel cleanly and energy-efficiently

Exhaust gas is safely expelled outside keeping the indoor air clean and odourless

Fully enclosed laminar burning process ensures a quiet sound level and dries the indoor air

Perfect for environmentally minded boaters and campers

Variable output eliminates system cycling and reduces noise

Brushless blower motor has a longer life-cycle and requires less frequent servicing

Feeding fuel directly from the main tank of the vessel saves space and eliminates the need for a separate tank

Durable Finnish design and manufacturing keep your Wallas running through tough weather conditions

Low temperature on unit and exhaust pipe for everyone’s safety

Two-in-one unit 

Ceramic stove is easy to install and keep clean

Laminar combustion is a safe flameless burning process
