Why choose diesel?

Wallas Diesel

Installing a cabin heater will significantly increase the length of your boating and camping season and keep you and your guests warm on cooler days. While you are out and about, heating with electricity is not the most practical option as it would deplete your battery too quickly. It may be better to consider other energy sources that won’t leave you stranded with an empty battery. Fuel burning or hydronic heating options typically work better if you stay away from the marina for long periods of time.

Diesel is a safe and convenient option for heating

As the combustion takes place in an enclosed chamber, the case surface temperature of a diesel heater stays low making it a safe option for all passengers and surrounding materials. Furthermore, Diesel heaters, stoves, and ovens do not have any exposed flame giving you peace of mind. They can be incorporated into the existing fuel system, so the fuel for the unit can be drawn directly from the fuel tank of your vehicle or vessel, which saves valuable space. Diesel is also conveniently available almost everywhere you go.

Silent combustion produces dry heat

Silent laminar combustion assures that you and your neighbors can sleep well without disturbing noise. Wallas units run smooth with a sound level similar to a humming of a refrigerator. For maximum comfort, a silencer can be installed, which reduces the sound level even further. Another factor that quality-conscious customers appreciate is laminar combustion produces clean dry heat, which keeps the interior upholstery and linens dry. Propane operated heaters, unfortunately, produce a considerable amount of moisture in the space leaving condensation on the windows and surfaces.

On the leading edge of ultra-low emissions

Despite the powerful air-flow, the burners in Wallas units produce ultra-low emissions, including very low CO2 and NOx levels. The exhaust gas is vented outside, so you can safely keep it running all night and keep windows and doors closed. Wallas-Marin develops products that can be run with current road and boat diesel, as well as renewable fossil-free diesel types. Wallas Greenboost burner has been calibrated to burn just the minimum amount of fuel that is needed. Typically only 0.1-0.5 l/h (3.4-16.9 oz/h).

If you plan to travel in snowy locations, diesel is recommended as propane is not suitable for freezing cold temperatures. When selecting the fuel type, take note of the temperature limits of each particular diesel fuel. The values provided here are to be treated as guidelines. Confirm the actual temperature limits from the fuel supplier.

HVO-Diesel, Diesel; summer grade: temperature must not fall below -5 °C (23 °F).

HVO-Diesel, Diesel; winter grade: temperature must not fall below -24 °C (-11 °F).

Diesel; arctic winter grade: temperature must not fall below -40 °C (-40 °F).

If the temperature drops below the minimum level, paraffin may form in the fuel. This may clog the fuel filter and pump. The clog will dissolve only if the fuel temperature rises well above +0 °C (32 °F). The less aromatic substances the fuel contains, the less deposits will be formed. Normal furnace oils contain 35-40 % of aromatic substances. In city diesel and green furnace oils (green diesel heating oil) the concentration is 20 %.
