ualified Boat Safety Scheme (BSS) examiner for inland waterway vessel inspections

Gas Safe Registered engineer for marine LPG gas installations and safety certificates

OFTEC certified technician for marine diesel heating and oil-fired appliance servicing

For inland waterway vessels, LPG remains a premier choice for integrated heating and hot water solutions due to its high energy density and immediate availability. However, the installation of gas-fired boilers and space heaters requires a specialised engineering approach to mitigate the risks associated with fuel density and combustion in confined marine environments. At Marine Heating Solutions, we provide expert technical integration for gas systems, ensuring that your on-board climate control is both high-performing and rigorously safe.

The Specialist Difference: Precision Marine Gas Engineering

The installation of an LPG boiler or heater is a complex task that must account for vessel movement, vibration, and strict ventilation requirements. Our engineering-led philosophy ensures every system is built to last.

  • System Soundness Testing: We utilise high-precision manometry to perform rigorous soundness tests, ensuring the entire gas circuit from the locker to the appliance is 100% leak-free.
  • Calculated Ventilation: We perform detailed fixed-air calculations to ensure your vessel meets the mandatory oxygen supply requirements for safe appliance combustion.
  • ISO 10239 Compliance: Every installation is engineered to meet the latest BS EN ISO 10239:2025 standards, utilising marine-grade materials and professional-grade mechanical joints.

Safety/Regulatory: GasSafe and Canal & River Trust (CRT)

To maintain your Canal & River Trust (CRT) license, all gas installations must strictly adhere to the Boat Safety Scheme (BSS) requirements. This includes specific mandates for flue terminals, gas locker drainage, and the installation of certified Carbon Monoxide alarms.

Our team consists of GasSafe registered engineers with specific marine competencies, ensuring that your heating system is installed to BS EN ISO 10239:2025 standards. We provide the necessary certification upon completion, which is essential for insurance validity and BSS certification.
