Navigating the corrosive environments of the UK’s inland waterways requires more than just standard heating components. Our high-performance ventilation systems are engineered specifically for boat owners who demand the highest levels of durability and thermal performance. By utilising marine-grade materials, these kits ensure that your exhaust gases are safely and efficiently vented, even in the most demanding conditions. At Marine Heating Solutions, we provide specialised engineering support for all flue installations, ensuring your system integrates perfectly with your professional boat heating installation.
Free Installation Offer Winter 2025/2026
We are currently providing professional fitting services at no extra cost for all flue kits purchased between November 15th, 2025, and February 15th, 2026. This limited-time offer ensures your system is fitted according to our rigorous safety standards by our qualified team.
The Specialist Difference: Efficiency-Led Marine Engineering
Our technical approach is built on providing long-term value through superior metallurgy. When it comes to longevity on the water, the choice of metal is critical. Unlike standard residential flues that may use lower-grade alloys, our kits are manufactured using 316L grade stainless steel for both the inner and outer skins. This material is exceptionally resistant to the acidic condensates produced by wood and diesel combustion, as well as the constant moisture and salt air common in coastal and canal settings.
Safety First: The 25mm insulation layer keeps the outer skin cool to prevent heat damage to your boat’s roof and bulkheads.
Corrosion Resistance: 316L grade steel prevents the “pitting” and premature failure often seen in cheaper alternatives.
Optimal Thermal Draw: High-density mineral wool insulation maintains hot internal gas temperatures for a stronger chimney draw.
High-Performance Thermal Insulation
Maintaining a high internal temperature is essential for creating a strong “draw” in the chimney. This ensures that smoke and harmful gases are pulled up and out of the cabin, significantly reducing the risk of carbon monoxide buildup—a vital consideration for compliance with Boat Safety Scheme (BSS) certificates.
