Wallas 85 NDP stove

Durable Surface Mounted Diesel Stove and Heater for Boats and Camper Vans

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. The elegant-looking blower lid is a forced air heater and a protective cover for the ceramic surface. The elegant blower lid not only adds a touch of sophistication but also functions as a forced air heater and protective cover for the ceramic surface. Simply lower the lid, and the stove begins to blow warm air, creating a cozy cabin atmosphere.

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. With E-mark approval, this stove is your trusted partner, not just on the high seas but also in the heart of your camper van adventures. 

When the lid is lowered down, it blows warm air for cabin heating

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, in addition to fossil-based diesel.

Combustion air is taken from inside the boat and exhaust gas is safely vented outside keeping the indoor air clean and odorless.

The exhaust gas also carries the moisture in the indoor air out keeping the air dry.

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

Perfect for environmentally minded boaters and campers.

Brushless blower motors have a very long life-cycle, supporting reliably long service intervals.

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.

Two-in-one unit.

Ceramic stove is easy to install and keep clean.

Heating power is controlled steplessly in Manual Mode with a knob.

Laminar combustion is a safe burning process with no exposed flame.

Unlike propane stoves, diesel stoves do not require gas inspections.

Kettle holder (accessory 1110) keeps pots safely in place if used in rougher weather.
