Chimney flue sizingFlue for canal Boat

When selecting a twin wall flue for your canal boat stove, you will want to make sure that you select the correct diameter of flue. The diameter you require will generally be determined by your stove. If you are not sure, check the stove manufacturer’s specification sheet. This will tell you what diameter flue pipe will connect with your stove’s chimney pipe.

Some customers remove the twin wall length when the boat passes under low bridges. Therefor we offer flue pipes with handles. Its just easier to lift with the handles.

We developed a special Deck Plate. Its to go on the top of the metal boat deck with bolts/screws and heat proof silicone sealant.

The winter closure plate fits over the top of the short length attached to  the deck plate, it just stops rain etc coming in if the length with handles is removed.

Most customers only have very short chimneys on boats typically 2.5 metres

Key Features of Our Twin Wall Boat Kit

Premium Material

Our twin wall boat kit is crafted from high-grade, weather-resistant materials. The inner and outer layers are engineered to withstand the toughest outdoor environments, ensuring longevity and reliability.

Optimal Insulation

The twin wall construction provides exceptional insulation, maintaining a comfortable interior temperature even in extreme weather. This insulation capability is crucial for prolonged outdoor trips, enhancing your overall experience.

Easy Installation

Setting up the twin wall boat kit is a breeze. The straightforward installation process ensures you spend less time assembling and more time enjoying your adventure. Consider how well the heat will spread through the boat. On a narrowboat, for example, it is better to locate the stove as central as possible. It will otherwise be difficult to spread the heat throughout the boat. Even though this can be overcome with radiators fitted to a back boiler, an even heat distribution is preferable.

British Standard

In response to calls around boat safety our reliable twin wall for narrow boats meets the  code of practice BSi 8511:2010, that requires the flue leaving to be twin wall insulated. 

This British Standard code of practice was published in Feb 2010 by the BSi and came into effect in Feb 2011. The code covers appliance selection, design considerations, installation requirements (including chimney arrangements), inspection and testing, and necessary safety information concerning maintenance and the safe use of solid fuel appliances on boats.

Available in 4” or 5” this is the perfect boat flue installation range for installing a small stove in  your canal boat, Dutch barge or wide beam.
