Living or leisure use of a narrowboat presents unique challenges and opportunities, particularly when it comes to cooking. Traditional gas cookers have long been the standard, but diesel-powered alternatives like the Wallas 88DU Diesel Hob and the Wallas 86D Diesel Oven offer a safer, more efficient, and more convenient option. Here’s why boats with Wallas diesel appliances make sense for narrowboaters.
1. Safety First: No Gas, No Worries
One of the biggest concerns with gas cookers is the risk of gas leaks, which can lead to fires or carbon monoxide poisoning, especially dangerous in the confined space of a narrowboat. Diesel, by contrast, is a far more stable fuel. It doesn’t ignite easily, and Wallas diesel appliances don’t rely on pressurised tanks or open flames.
- No gas leaks: Diesel systems eliminate the need for LPG cylinders, regulators, and piping, reducing the number of failure points.
- No open flame: The Wallas 88DU and 86D operate with a sealed combustion system, drastically reducing fire risk.
- External exhaust: Fumes and moisture are vented outside the boat, improving onboard air quality and reducing condensation.
2. Cleaner and Drier Operation
Cooking with gas introduces moisture and exhaust fumes into your cabin, contributing to condensation and mould. Wallas diesel appliances burn fuel extremely efficiently and are externally vented, meaning the byproducts of combustion—heat, water vapour, and exhaust—exit the boat entirely.
- Reduced condensation inside the cabin.
- Better air quality, especially important during winter when windows and vents stay shut.
- More comfortable environment for extended onboard use.
3. Fuel Efficiency and Simplicity
Diesel is already widely used on narrowboats for propulsion and heating, so choosing diesel cooking appliances means one fuel system for everything. No need to haul heavy LPG bottles down towpaths or make special trips to refill them.
- Easier logistics—top up diesel at most marinas.
- Lower running costs over time.
- Integrated system simplifies boat maintenance and refuelling routines.
4. Modern Technology and Scandinavian Reliability
Wallas, a Finnish brand with decades of marine heating and cooking experience, builds their products for harsh Nordic conditions, making them perfect for British waterways. The 88DU and 86D feature:
- Thermostatic controls for precise cooking and baking.
- Electric ignition for ease of use—no matches or gas lighters required.
- Quiet operation and sleek, minimal design.
5. Compliance and Insurance Benefits
Many insurers are increasingly wary of LPG systems due to the associated risks. Switching to diesel appliances like the Wallas 88DU and 86D can:
- Lower insurance premiums by reducing fire and explosion risks.
- Simplify Boat Safety Scheme (BSS) compliance, as fewer gas-related checks are needed.
Final Thoughts
Switching from a gas cooker to the Wallas 88DU diesel hob and 86D diesel oven is not just an upgrade in convenience—it’s a significant step forward in safety, efficiency, and comfort.
With cleaner air, less moisture, reduced risk of fire or leaks, and the convenience of one fuel source, diesel cooking systems are a smart choice for today’s narrowboaters. In a space where every square inch counts and safety is paramount, Wallas diesel appliances offer peace of mind without compromise.
Now, having said all that, it’s probably not cost-effective to swap from gas to diesel. However, if you are having a new narrowboat built to your specification or you are planning or are in the process of a big refit, then you could do worse than consider the diesel hob and over alternative.
