Wallas 86 D oven

See Your Boating Life in a New Light

Wallas 86 D is one-of-a-kind diesel oven that will bring your off-grid life to a new level. The world’s first automatic diesel convection oven has a thermostat-controlled fan for fast and accurate cooking times. As there is no open flame, it is safe to use at high temperatures and the fuel consumption is so low that an hour of cooking will only require approximately 0,25 l (8.5 oz) of fuel. Diesel can be drawn from the main fuel tank of your boat, which saves a tremendous amount of space aboard. High-grade aluminum and stainless steel keep your Wallas oven looking great for years. 86 D is as easy to operate as a domestic oven. Simply start it by a press of a button and choose the desired temperature by turning the stepless thermostat knob. It can be installed together with Wallas stoves for a complete off-grid cooking solution for demanding chefs.

Cleaner Burning

Updated software optimizes fuel and electricity consumption

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

Larger burner burns fuel slower resulting in ultra low CO2 and 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.

Perfect for environmentally minded boaters and campers.

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

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

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

Domestic style convection oven cooks evenly.

Thermo sensors maintain a precise temperature level for fast and accurate cooking times.

Unlike propane cooking systems, Wallas 86 D diesel oven does not require gas inspections.
