The Bubble 4B solid fuel boat stove is a robust and highly efficient rectangular multi-fuel burner designed to meet the rigorous demands of marine life. Delivering a powerful 5kW heat output, this stove is the perfect solution for medium-to-large narrowboats and cruisers where consistent, reliable warmth is a priority. Featuring a large firebox and deep ashpan capable of holding enough fuel for 24-hour continuous burning, the Bubble 4B ensures your vessel remains dry and comfortable even during the peak of winter.
Bubble 4B: High-Performance Multi-Fuel Marine Heating
The Bubble 4B stove is engineered with advanced thermal technology to squeeze every drop of heat from your fuel, whether you are burning seasoned wood, peat, or smokeless fuel. Its high-temperature firebox lining system ensures complete combustion, significantly reducing smoke and particulate emissions. For added versatility, the 4B includes a lovely cook top as standard, allowing you to simmer or fry meals while the stove is in operation. This model also features an airwash system to keep the door glass clear, providing a beautiful view of the pyrotechnics within.
Hot Water and Central Heating Options
To extend the reach of your heating system, the Bubble 4B can be equipped with an optional 2kW back boiler. This allows the stove to function as a central heating boiler, powering radiators at the far ends of the boat or heating domestic hot water via a calorifier. To ensure safety and regulatory compliance, all installations should follow the official Boat Safety Scheme (BSS) guidelines for solid fuel stoves. We also recommend our Bubble 4B Solid Fuel Narrowboat Stove Kit, which includes a BSS-compliant twin-wall flue kit to prevent heat transfer to the boat’s structure.
