Wallas 87 D oven-stove

Spice Up Your Off-Grid Living with an Oven-Stove Combination

Wallas 87 D diesel stove-oven is one-of-a-kind forced air cooking system 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. With no open flame, it’s safe for high-temperature use, and its fuel consumption is remarkably low, requiring only approximately 0.25 liters (8.5 oz) of fuel for an hour of cooking. Diesel can be drawn from the main fuel tank of your boat or vehicle, which saves a tremendous amount of space aboard. Wallas 87 D is as easy to operate as a domestic counterpart. Simply start it by a press of a button and choose the desired temperature by turning the knob. Cook your recipes on the left-side plate of the stove and simmer on the right at a slightly lower temperature. Wallas 87 D is perfect for long boating trips, when you want to have the same quality meals you are accustomed to have at home.

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 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.

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.

Wallas 87 D is a combination of 86 D oven and 85 DP stove.

Domestic style convection oven cooks evenly.

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

Ceramic stove is easy to operate and keep clean.

Unlike propane cooking systems, diesel stove-oven does not require gas inspections.
