Unlike the hazardous propane systems, it uses diesel in its task as a responsive high temperature stove that will give years of service.

The Wallas diesel stove draws combustion air from inside the cabin and carries exhaust outside the cabin. In a boat, this feature forces fresh air into the cabin area, drying the vessel interior and reducing the effects of mildew.

A red indication LED in the ceramic glass top warns if the stove is hot.

Get rid of propane and forget about carrying heavy gas bottles into your boat. Save gas bottle lockers space for better uses. The Wallas diesel combustion process eliminates the need for hazardous heavier-than-air gaseous fuels.

No naked flame
An open flame is always hazardous and also creates moisture in your boat or RV/caravan. Unlike propane systems, Wallas stoves draw combustion air from the cabin and exhaust overboard. This process dries the interior.

To ensure highest quality, every single Wallas product hand made in Finland and is carefully tested before delivery.

People often ask, “How do diesel cooktops compare with gas, and how long does it take to boil the jug?” Well, it depends on a few factors, but to keep it short the answer is it does take a little longer.

We have done some heating tests on our Wallas cooktops. We used an XC Duo, but the following applies to all Wallas diesel cooktops. Lets look at a few things. Gas is instantaneous heat, Wallas diesel cooktops require time to get started. After doing some tests we found that with 2.0L of water in a jug at 16.5 °C using gas it takes 13 minutes while using a diesel cooktop it takes 18 minutes to boil.

The drawback with diesel cooktops is that it takes 12 minutes for the cooktop to reach maximum temperature (500 °C ) making the total time to “boil the jug” 30 minutes from stove switch on. It does take some planning when using diesel; when you get up in the morning to “boil the jug” and do what nature needs you to do, just turn the cooktop on and when you come back it is up to temperature ready to put the jug on. Of course, if the stove is already on from boiling the jug, cooking brekkie right after will save that startup time.

When you are on holidays, does 10-15 minutes extra make a difference when compared to the enormous advantages of Wallas diesel cooktops over gas (safer, no condensation, cheaper to run, easier to fill, no compliance issues)? You, the customer, need to work that out for yourselves, but here at Dieselheat, we think the benefits usually speak for themselves.
